Bhringraj (Eclipta alba)

Bhringraj (Eclipta alba)



Introduction 
Since the time of Ayurveda till today Bhringraj (Eclipta alba) is a top-notch herb used in hair care industry. Bhringraj is a widely celebrated medicinal plant, especially in India, used singly or in combination with other herbs such as amala, shikaakai for making a vast range of hair care, hair rinse and conditioner products. Bhringraj oil when massaged on to the scalp; imparts a (Eclipta alba)calming effect and promotes a good sleep. [1]
Descriptions of the medicinal properties of the herb by Arab writers are similar to those by their Indian counterparts. According to J.J. Wood, in hepatic derangements Eclipta prostrata is of greater service than Taraxacum.
The Sanskrit word Bhringraj literally means that which imparts hair the splendid color like that of a humming bee. It has numerous epithets describing its properties of promoting the growth of hair, preventing balding and premature graying and making them black and lustrous.  Kesharaaja, literally means king of the hair or king for hair care, ruler of the hair, unravels its inbuilt qualities regarding the health of the hair, Markava that which prevents premature graying and Keshranjanaa that which imparts beautiful tinge to hair.
According to Waagbhata, a person who consumes a fresh juice of Bhringraj daily for a month and stays on a diet predominantly of milk, is rejuvenated and lives a strong, healthy and happy life of 100 years. [2], [3], [4]
The name of the genus Eclipta (Ek-lip-tuh --) is derived from Greek ‘ekleipo’ meaning ‘deficient’ referring to the absence of calyx. [5]
Though it is not described by Brihat-trayee in ganas and wargas, in therapeutics it is an important herb. Charaka recommended it for raktapitta. In Raja-Nighantu the blue Bhringraj is extolled to be the best (? One of the best) rasaayana (rejuvenator)
In modern times its hepatoprotective role is well documented. [6]

Geographical Distribution
Bhringraj is a creeper growing commonly in moist places. It grows as a common weed on the hills and up to the height of 6,000 ft in the Himalayas. Though the plant is widely distributed throughout India it is more common in areas of upper Gangetic plains, in pasture lands, along roadsides in Chhota Nagpur, all districts of Bihar and Orissa, Punjab, Western India and South India. It is found in China, Thailand, Brazil  and Southwestern America. Now it is cultivated all over the world. [9], [10]
Bhringraj (Eclipta alba) is a moisture-loving creeper. It is an annual, erect or prostrate, much branched, entirely pubescent (covered with hairs), rooting at the nodes. It grows 3 feet tall. The plant flowers in September and fruits in November





Roots of the plant are well developed, cylindrical and grayish in color. A number of secondary branches arise from main root











Stem is short, up to about 7 mm in diameter, flat, round or cylindrical, grayish or brown in color, rough due to hairy branches, node distinct



  



Leaves are opposite, sessile, usually oblong and lance shaped, 2.5 to 8.5  cm long, 1.2 to 2.3 cm wide, blackish green in color with white appressed (lying flat or pressed closely against something as hairs on certain plant stems) hairs on both sides and serrated edges








 Flower solitary or 2, together on unequal axillary peduncles; involucral bracts (inflorescence in a specialized leaf), about 8, ovate, obtuse or acute, herbaceous, strigose (having short, stiff, appressed hair); white disc flowers tubular, corolla often 4 toothed; stamen 5, filaments epipetalous, free, anthers united into a tube; ovary inferior, unilocular with one basal ovule. In Indian conditions the flowering time is from October to December






Fruit is achene (a type of simple dry fruit) compressed, narrowly winged and 6-8 mm in diameter, having one black colored seed









Seed 0.2 to 0.25 cm long, 0.1 cm wide, dark brown or black in color, resembling cumin seeds, cuneate (wedge shaped) with a narrow wing, hairy and non endospermic




According to the colors of the flowers the herb bears; in Ayurveda three varieties of Bhringraj are described:
1.  White (Eclipta alba) 
2.  Yellow (Widelia calendulacea)
3.   Neela Bhringraj, Neeli Bhringraj (Indigofera tinctoria) [14]
Probably this is why there are many taxonomic names. In this article the author lays stress on E. alba. In fact Eclipta alba L. andEclipta prostrata L. are synonyms. In their research works some scholars preferred E. prostrata to E. alba. I have not altered their terminology but honored it. [15]
Although the names Eclipta alba and Eclipta prostrata are used as synonyms Rechinger (1977) they are two different species.
Among North Indian populations, three morphotypes of Eclipta alba are identified i. e. erect, semierect and prostrate. The erect plants are tall and upright while the prostrate variety has all creeping branches. The semierect variety has lower parts of branches creeping and tips are ascending.[16]

Phytochemistry
The plant extract is resinous in nature and contains the alkaloid ecliptine. The herb is a rich source of ascorbic acid and thiophene derivatives.
The chief constituents of the herb are coumestan derivatives such as wedelolactone, demethylwedelolactone and desmethyl-wedelolactone-7glucoside. Wedelolactone is classified as a coumestan. Coumestan is a derivative of coumarin. Because of the estrogenic and steroid-like activity of some coumestans, a variety of synthetic coumestans have been developed so as to explore their pharmacological effects.
The other constituents are ecliptal, ß-amyrin, luteolin-7-O-glucoside, apigenin, wedelic acid, hentriacontanol, heptacosanol, stigmasterol, polypeptides, polyacetylenes, thiophene-derivatives, steroids, triterpenes and flavonoids, alkaloid ecliptine and nicotine.
The occurrence of mono-, di- and tri- thiophene acetylenes together with a-terthenyl in some species is noteworthy.

Wedelolactone
Molecular formula: C16H10O7                                                
Structural formula:
          [38]
Wedelolactone (WDL) belongs to the flavonoids category of phytoestrogens. It was originally extracted from Eclipta alba(Eclipta prostrata). Later extracted from Wedelia chinensi, is a major coumestan ingredient of the herb.
In one study wedelolactone has been shown to inhibit caspase-11 which is a key regulator of proinflammatory cytokine IL-1Beta maturation and pathological apoptosis. It also inhibits IKKy, a kinase that activates NF-kB.
Wedelolactone showed hepatoprotective activity protecting cultured liver cells from the toxicity of CCl4, Phalloidin and Galactosamine.
Wedelolactone inhibits 5-LO (lipoxygenase) activity in porcine leucocytes. [39]
The synthetic wedelolactone stimulates RNA synthesis in isolated nuclei from hepatocytes  [39], [40]
Previous findings that wedelolactone inhibited IKK activity and caspase-11 expression which resulted in the activation of NF-kB pathway suggested that wedelolactone could be a potential lead compound in anti-inflammatory therapy. However according to some experts the mechanism of anti-inflammatory activity of wedelolactone is unclear.
Previous studies have shown that wedelolactone has antihepatotoxic, antiandrogenic and anti- human immunodeficiency activities. In China it has been in vogue to treat septic shock, viral hepatitis and venom poisoning. [41], [42]
In Punjab and Gujarat, India Bhringraj has been used externally as antiseptic to treat infected wounds and ulcers in cattle and to treat many microbial infections in rural areas of India. The results of recent studies revealed that wedelolactone may be the main constituent in Bhringraj, (Eclipta alba) responsible for antimicrobial activity of the herb. Studies have also shown that wedelolactone has anti-bacterial, anti-viral and anti-fungal activity. Wedelolactone showed antibacterial activity against S. typhimurium, S. epidermidis, B. subtilis and E. coli. [43]
Wedelolactone shows a significant anti-HIV-1 activity [44]
Wedelolactone induces caspase-dependent apoptosis in prostate cancer cells. Wedwlolactone has bee found to modulate androgen receptor (AR) activation of transcription from prostate specific antigen (PSA) promoter in prostate cancer cells. [45], [46]
The anticancer activity of wedelolactone has also been shown in androgen receptor negative breast cancer cells. Wedelolactone arrested the growth of cancer cells at the S and G2/M phase of the cell cycle by damaging DNA. [47]
Human Epithelial type-2 cells originate from human laryngeal carcinoma. wedelolactone induces apoptosis in these cells in combination with LPS and Poly-isnosinic acid: Polycytidylic acid. [48]
Coumarins                      
Coumarins possess anti-inflammatory, anti-oxidant, anti-coagulant, analgesic, immunemodulatory, anti-bacterial, anti-HIV and anti-tumor (anti-cancer) activities. [49]
Coumarins are vasoconstrictors, decrease capillary permeability, inhibit histamine release from mast cells. They possess mild adrenergic activity.
Coumarins also exhibit anti-inflammatory, antipyretic, antibacterial, antifungal properties. Coumarins are also useful in the treatment of High Protein Lymphedema (HPLO), chronic infections, disorders of immune system and cancers.[50]
Oleanolic acid
Molecular formula: C30H48O3
Structural formula:
Oleanolic acid is a naturally occurring triterpenoid widely distributed in food and medicinal plants. It exhibits antiviral, hepatoprotective and anti tumor properties. [51]
Oleanolic acid has anti-inflammatory, hypolipidemic and hepatoprotective properties.
Oleanolic acid is useful in neurodegenerative disorders like Alzheimer’s disease [52], [53]
Amyrins
Molecular formula: C30H50O
Structural formula:
       
   α  Amyrin                                         β Amyrin
Amyrins are a pair of closely related triterpenes. They are designated as α Amyrin and β Amyrin. Each has the chemical formula C30H50O. They are isolated from a variety of plant sources. [54]
In mice 500mg/kg acetaminophen caused fulminant liver damage. Pre-treatment with α and β Amyrins with 50 and 100 mg/kg at 48, 24and 2 hours before acetaminophen, attenuated acute liver injury as was proved by biochemical and histopathological studies. [55]
Animals pre-treated with the oral dose of 50, 100 and 200 mg/kg of α and β Amyrins block histamine and serotonin receptors and relieve itching. In addition α and β Amyrins at the dose of 100mg/kg prevent degranulation of mast cells and are now known as mast cell stabilizers. Amyrins do not show sedative activity. These properties of Amyrins found in Bhringraj (Eclipta alba) (E. alba) can be exploited to treat pruritus associated with jaundice. These actions are due to the stabilizing action of Amyrins on the mast cell membrane. [56]
Beta-amyrin palmitate at doses of 5, 10 and 20mg/kg body weight exhibit sedative activity; the effect of course is dose dependant. [57] 

Orally administered α and β amyrins (found in E. alba) selectively bind to CB (1) and CB (2) receptors and inhibit inflammatory and persistent chronic neuropathic pain. [58]
The anti-inflammatory activity of amyrins is attributed to their ability to inhibit prostaglandins and suppress COX-2. Amyrins also block the activation of NF-κB. [59] 
Antilipoxygenase activity of amyrins suggests that they have a beneficial role in the treatment of arthritis. [60]
The mixture of α-β-amyrins exhibit anti nociceptive properties [61]

In mice α and β amyrins demonstrated significant anti-nociceptive activities against subplantar or intracolonic application of capsaicin [62]

In mice α and β amyrins demonstrated significant anti-nociceptive activities against cyclophosphamide induced bladder pain and intracolonic administration of mustard oil [63]

Alpha and beta amyrins exhibit anxiolytic activity. [64]
To evaluate beneficial effects of α and β amyrins in pancreatitis, by using cerulein acute pancreatitis was induced in mice. The animals were then treated with α and β amyrins. The treatment decreased the elevated levels of tumor necrosis factor-α, interleukin-6, lipase, amylase, myeloperoxidase (MPO) and thiobarbituric acid reactive substances (TBARS). Further more α and β amyrins suppressed the pancreatic edema, inflammatory cell infiltration, acinar cell necrosis and expression of TNF-α and iNOs suggesting α and β amyrins are useful for the treatment of acute pancreatitis.
Similar protective effects of α and β amyrins were observed in acute pancreatitis induced in rats by using L-arginine [65], [66]
In mice α and β amyrins showed gastroprotective effect against ethanol-induced gastric mucosal damage. At the dose of 100mg/kg the gastroprotective effect was maximum. The gastroprotective effect involves the activation of capsaicin-sensitive primary afferent neurons. [67]
By suppressing inflammatory cytokines and COX-2, possibly via NF-κB and CREB (cAMP response element-binding protein)-signaling pathways α and β amyrins demonstrated protective effect against trinitrobenzene sulphonic acid-induced colitis in Swiss male mice
Protective effect of α and β amyrins was also observed in mice against dextran sulphate-induced colitis. It was hypothesized that the cannabinoid pathway may be involved in this regard. [68], [69]

In experimental on isolated rabit jejunum preparations triterpene compounds α and β amyrins expressed antispasmodic activity. [70]

In mice pretreatment with α and β amyrins at the doses of 50 and 100mg/kg at 48, 24 and 2 hours before administration of acetaminophen attenuated the acetaminophen-induced liver damage [71]

In mice, α-amyrin, by reducing elevated bold sugar levels improved diabetes in streptozotocin-iduced diabetes [72]

In streptozotocin-induced diabetic rats α-β-amyrins reduced elevated levels of blood glucose, total cholesterol and serum triglycerides. At the dose of 100mg/kg there was significant reduction in TC, TG, L and VLDL levels and elevation in the level of HDL cholesterol. These amyrins also lowered the lipid levels in normoglycemic rats. [73]

Ursolic acid
Molecular formula: C30H48O3
Structural fopmula 
 
Ursolic acid is a pentacyclic triterpenoid. It is present in many medicinal plants such as Bhringraj  (E. alba), basils, apples, cranberries etc. In vitro by inhibiting the STAT3 activation pathway and inducing apoptosis, ursolic acid inhibits the proliferation of various cancer cells. Ursolic acid also inhibits JNK expression and IL-2activation of JURKAT leukemic T cells leading to the reduction in proliferation and T cell activation.
Ursolic acid can serve as a starting material for synthesis of more potent bioactive derivatives such as experimental antitumor agents. [74]
Ursolic acid has anti-inflammatory, antioxidant, anti-microbial, anti-HIV, hepatoprotective, anti-tumor, cytotoxic and anti-cancer properties. Ursolic acid prevent wrinkling of the skin. [75], [76]
Ursolic acid increases the amount of muscle and brown fat and decrease white fat. By increasing Akt activity in skeletal muscle it inhibits muscle atrophy and promotes muscle growth. Consistent with increased skeletal muscle and brown fat, ursolic acid increases energy expenditure, improves glucose tolerance and decreases fatty liver disease. Thus it is useful in the treatment of obesity. [77]
To take the advantage of these activities Korean sport scientists advise the athletes to consume 450mg of ursolic acid every day. The study of the use of ursolic acid by athletes is recorded in the Korean Journal of Physiology and Pharmacology. [78]
In experimental studies ursolic acid has been shown to target cell cycle proteins, growth factors, kinases, cytokines, chemokines, adhesion molecules and inflammatory enzymes. These targets can potentially mediate the chemopreventive and therapeutic effects. [79]
By inducing cell cycle arrest and apoptosis ursolic acid exhibits anticancer effects in various human cancer cell lines in vitro, especially in gall bladder cancer. [80] 

Luteolin

Luteolin has anti-inflammatory, anti-oxidant, antiallergic cardioprotective properties. The cardioprotective role has been shown in cardiomyocytes following ischemia-reperfusion. This suggests that leuteolin can be used for preventing and treating ischemic heart disease. [81], [82]

By blocking carcinogenic stimuli, inhibiting tumor cell proliferation and induction of cell cycle arrest or apoptosis luteolin blocks the development of cancer cells both in vitro and in vivo. [83]

By suppression of cell cycle pathways and stimulation of apoptosis leuteolin sensitizes cancer cells to anti-cancer chemotherapeutic drugs. [84]

Apigenin

Apigenin has anti-inflammatory and anti-oxidant properties. It has beneficial effect in cardiovascular and neurological disorders. [85]

A recent study shows that apigenin can inhibit the growth of cancer cells, sensitize cancer cells to chemotherapeutic agents, induce apoptosis in cancer cells and inhibit neoangiogenesis [86]

In an experimental study on Charles River Sprague-Dawly CD rats Eclipta prostrata at doses of 50mg/kg and 100mg/kg exhibited antioxidant effect. [94], [95], [96]
In an experimental study on rats global ischemia reperfusion injury was induced by occluding both common carotid arteries for 30 min, followed reperfusion for 4 hrs. Pretreatment with hydroalcoholic extract of E. alba significantly reduced the edema, the size of cerebral infarct and reversed the biochemical markers [97]
Immunomodulatory activity
Wedelolactone and demethyl-Wedelolactone in E. alba enhance the non-specific immune response and resistance to various diseases. The aqueous extract of leaves of E. alba enhances humoral and cellular immunity.
The results of the study suggest that dietary intake of the extract of E. alba leaves can enhance immunity in humanbeings. [98], [99]
Antimicrobial Activity
The wedelolactone contained in E. alba shows antibacterial action against Staphylococcus aureus, Staphylococcus epidermidis(at concentration of 15.0 μg /ml), Salmonella typhimurium (at the concentration of 25.0 μg /ml) and E. coli. [100]   
Anti-viral Activity
E.alba shows antiviral activity against Ranikhet viral disease.  Dasyscyphin-C, a newer saponin compound extracted from the leaves of E. prostrata shows antiviral activity against fish nodavirus, grouper nervous necrosis virus (GNNV).   
The methanolic extract of leaves of E. alba (Dose: 250-750 mg/kg) produced schizonticidal effect on Plasmodium berghei in mice. [101]
In an experimental study the ethanolic extract of whole plant of Eclipta alba at concentrations 1.0, 2.0, 5.0, and 10.0 mg/ ml exhibited antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Escherichia coli, Proteus mirabilis, Pseudomonas fluroescens, Pseudomonas aeruginosa and Salmonella typhi. The antibacterial activity was comparable with that of the standard antibiotic penicillin (10mg/L). [102]
Antifungal Activity:
25beta-hydroxyverazine showed good activity against Candida albicans (Abdel Kader et al., 1998). The in vitro antifungal activity of whole plant of E.alba extract was investigated against Candida tropicalis, Rhodotorula glutinis and Candida albicans. The extract showed high degree of activity against all test fungi. The inhibitory effects of extracts are very similar to those of standard antibiotics used
The extract of whole plant of E. alba and particularly 25 beta-hydroxyverazine fraction of it showed good antifungal activity against Candida albicans, Candida tropicalis and Rhodotorula glutinis and many other fungi tested. The inhibitory effects were very much similar to those of standard antifungal antibiotics. 
According to some research workers E. alba works better than Amphotericin B in fighting fungal infections.  [103] 
Anti-protozoal Activity   :
The anti-malarial activity of Eclipta alba leaves extract was evaluated against Plasmodium berghei ANKA strain in mice. A standard inoculum of 1 x 10(6) infected erythrocytes was used. The methanolic leaf extract (250-750 mg/kg) produced a dose-dependent chemosupression or schizontocidal effect during early and established infection and high mean survival time values particularly in the group administered 750 mg/kg/day of extract. [104]
Its effects on the other species of Plasmodium need be evaluated.
Eclalbosaponins are active against Giardia intestinalis.
Dasyscyphin C extracted from E. prostrata is leishmanicidal. At the concentration 450μg/ml death of the parasite L. major, was 73 percent. The other species viz. L. aethiopica and L. tropica were less sensitive to the saponins of E. prostrata.
Thiophene derivatives are active against nematodes. Triterpenoid and saponins are antiproliferative and Leishmanicidal. [105]
Antimalarial Activity
At doses 250-750 mg/kg bodyweight the methanolic extract of E. alba produced a dose-dependent schizonticidal effect against Plasmodium berghei. [106]  
Hexane, ethyl acetate, benzene, chloroform and methanol extract of leaves of E. alba exhibit larvicidal and ovicidal activities. Thus E. alba can be useful in combating malaria through its larvicidal and ovicidal activities. [107], [108]
Anthelmintic Activity
Anatomically and physiologically earthworm (Pheretima posthuma) resembles roundworm (Ascaris lumbricoides). To evaluate anthelmintic activity of Eclipta prostrata, in an experimental study, earthworm was used instead of roundworm.
At concentration with 100mg/ml ethanol and aqueous extracts of Eclipta prostrata caused paralysis in 2.5 minutes and death in 24.8 minutes of worms studied. This showed that ethanol and aqueous extracts of E. prostrata have significant anthelmintic activity against Ascaris lumbricoides (round worms). The anthelmintic activity was dose dependent. In this regard the ethanolic extract was superior to aqueous extract. The anthelmintic activity of E. prostrata was comparable to Albendazole. [109]
Actions on CNS
Ecliptalbine and verazine show analgesic activity.
In one study on albino mice, analgesic effect of E. alba was studied using ethanolic and alkaloidal extracts of E. alba in standard experimental models. Both the extract showed analgesic activity but the alkaloidal fraction was the most efficacious in all models tested. [110], [111]
The aqueous, hydroalcoholic extracts and hydrolyzed fraction of the aqueous extract of E. alba were subjected to neuropharmacological activities (sedative, muscle-relaxant, anxiolytic, nootropic and antistress activities) in rats. The findings indicated nootropic activity of the aqueous extract (300 mg/kg, p.o.) and its hydrolyzed fraction (30 mg/kg, p.o.). The aqueous extract and the hydrolyzed fraction exhibited gastro protective effect (anti-stress activity) and normalized the white blood cell count in the milk induced leukocytosis challenge model [112]
The aqueous extract of leaves of Eclipta alba when administered to mice at doses of 100 1nd 200mg/kg body weight improved their cognitive function. This activity was attributed to the presence of leuteolins present in the extract [113]
In animal model (rat) the methanolic extract of the whole plant of E. alba at the dose of 200mg/kg ameliorated oxidative stress, improved memory and arrested the progression of Alzheimer’s disease [114]
Antiepilepsy Activity
The methanol extract of leaf powder of E. alba administered to rats (Dose: 50, 100 and 200mg/kg body weight) exhibited anti-convulsant activity. This effect was attributed to wedelolactone, α and β-amyrins and luteolin present in the extract. [115], [116]
The suspension of E. alba containing 100 and 200 mg/kg was administered to rats to evaluate Transfer Latency on an elevated plus maze. Mice were placed at the center of open field apparatus to assess spatial habitual learning, observed for 20 minutes for rearing and time spent during rearing using varied doses for 30 minutes, 24 hours and 96 hours and 144 hrs. The results revealed significant improvement of retrieval memory [117]
Actions on Behavior
The aqueous extract of E. alba at the dose of 300mg/kg acts as memory enhancer and cognitive enhancer (nootropic) in rats.
The suspension of E. alba at the doses of 100 and 200 mg/kg revealed significant improvement in special habitual learning and retrieval of memory in rats [118]
Anti aggressive effect:
In rats E. alba (200mg/kg) significantly minimized dominance which is correlated to the level of aggression. A tangible behavioral submission was also observed with the dose 100 and 200 mg/kg.
It has been suggested that these effects of E. alba are probably due to its immunomodulatory action on the nervous system. [119]
Actions on Skin and Hair growth
An Ayurvedic formulation containing powder of E. alba has been shown to provide complete remission and prevent the recurrence of eczema in dogs. [120]
The antioxidant property of aqueous extract of E. alba protects the skin against ultra-violet irradiation-induced skin damage. [121]
The study was aimed to investigate the efficacy of methanol extract of E. alba as hair growth promoter. Pigmented C57/BL6 mice, preselected for their telogen phase of hair growth were used. The extract was applied topically to assess telogen to anagen transition. The methanol extract of whole plant when tested for hair growth promoting potential, exhibited dose dependent activity in C57BL6 mice (Datta et al., 2009) [122]
Bhringraj (Eclipta alba) is a topnotch herb for hair care. Hair regrowth has been noted in repeated studies with the petroleum ether extract of E. alb leaf. Its potency rivals that of 2% solution of Minoxidil. According to one study, combination thrapy of Eclipta Alba with two other herbs (Citrullus Colocynthis andCuscuta Reflexa) has outperformed Minoxidil in hair groth activity. [123]
Eclipta alba promotes hair growth and maintains its luster and black color. The appropriate concentration for this activity is 10%w/v. In the reported work, petroleum ether and ethanolic extracts were incorporated into water in oil cream base were applied topically on shaved skin of albino rats. The results of this application were better than the use of 2% and 5% minoxidil treatment [124], [125], [126]
Bhringraj (E. alba) oil is useful for the treatment of graying of hair.
A simple hair pack made with fresh leaves is effective in preventing baldness. Apply the paste of fresh leaves on the scalp. Wait for 15-20 minutes before washing. Use this once a week for good results. [127]
Effects on wound healing
Due to its antioxidant, anti-inflammatory, free radical scavenging and antimicrobial activities it promotes wound healing. (Dose: Ethanolic extract 150 to 300 mg/kg body weight).  [128]
Actions on the Eye
Eye health does not have any direct studies on it despite its historical claims, although the one human intervention noted that 7.5% of the sample consuming 3g of the leaves daily claimed they had better eyesight; this study was blinded, and constitutes the only evidence for eye health claims. In a way it is promising (3g of the leaves themselves over 60 days improving eye health even when paricipants were unaware this could be an effect of treatment) but it does not constitute sufficient evidence in and of itself.
Beyond the possible eye/hair benefits and the liver protection, other possible benefits of Eclipta Alba are lessened anger (two animal studies, moderate oral doses), pain reduction (dose dependent, which outperfomed Aspirin when consumed at higher doses of 500mg/kg rats; 80mg/kg ethanolic extract in humans) a reduction in blood pressure, diuretic effects, with at least one study suggesting some benefit to the immune system (increasing macrophage and white blood cell activity).
A possibly promising herb for wellness and beauty, but requires more studies on it. [129]
Actions against snake bite
Wedelolactone and demethylwedelolactone found in E. alba and E. prostrata have trypsin inhibitory and styptic (antihemorrhagic) activity against Malayan Pit Viper venom.
Walter B. Mors et al, Maria Helena da Silva et al and Paulo A. Melo et al showed that in Swiss mice, the ethanolic extract of the aerial parts of E. prostrata neutralized the lethal activity of South American rattle snake venom. According to them the aqueous extract of E. prostrata inhibits the release of creatine kinase from isolated rat muscles exposed to the crude venom. They attribute these effects to wedelolactone, sitosterol and stigmasterol.
Ethanolic extract of the aerial parts of E. alba neutralizes three lethal activity of the venom of South American rattle snake (Crotalus durissus terrificus) by inhibiting snake venom phospholipase A2 activity. The inhibitory activity has been attributed to wedelolactone, demethylwedelolactone, coumestan, stigmasterol, and sitosterol present in the extract.
In one study aqueous extracts of E. alba inhibited the release of creatinine kinase from isolated rat muscle exposed to crude venom. This protection was also observed in vivo, when the venom was preincubated with the plant extract in mice.
In neutralizing myotoxins wedelolactone was more effective than sitosterol and stigmasterol. Wedelolactone inhibited the hemorrhagic effects of B. jararaca venoms. This activity was attributed to inhibition of proteolytic activity of B. jararaca venom [130], [131]
Actions on Musculo-Skeletal System
Flavonoid, diosmetin, and isoflavonoids, 3’hydroxybiochanin A, and 3’O-methylorobol, isolated from the methanol extract of E. prostrata significantly increased osteoblast differentiation as assessed by the alkaline phosphatase activity [132]
Actions on RS
Wedelolactone which is anti-allergic, is a potent phytochemical against bronchial asthma. [133]
Actions on CVS
To evaluate antihypertensive effect of E. alba, dried leaf powder of E. alba was administered to mild hypertensive subjects, six capsules of 500mg each for 60 days. The sudy indicated that the leaf powder possessed diuretic, hypotensive and hypocholesterolemic properties [134]
The ethanolic extract of leaves of E. alba showed negative inotropic and negative chronotropic effects on frog heart. The extract reduces cardiac output. It antagonizes the effects of adrenaline. [135], [136]
Effect on proteolytic and hemorrhagic activities
Wedelolactone and demethylwedelolactone, isolated from E.alba demonstrated significant trypsin inhibitory effects. The partially purified ethyl acetate extract of E. prostrata (containing 47% of wedelolactone) and wedelolactone demonstrated strong antiproteolytic and antihemorrhagic activity against Malayan Pit Viper venom in a dosedependent manner. The extract, at 5 mg/ml, inhibited proteolytic activity of 100 µg of the venom and hemorrhagic activity of 3 minimum hemorrhagic doses to 95% and 65% respectively. At the same concentration, wedelolactone neutralized the proteolytic activity at around 76% and, at doses of 0.25-1.0 mg/ml, offered protection against hemorrhagic activity of the venom in the range 3-3.5%. [137]
Actions on GI System
The aqueous extract and the hydrolyzed fraction exhibited gastro-protective effect and normalized the white blood cell count in the milk injection induced leukocytosis in laboratory models. [138]
E. alba significantly reduces the gastric acid secretion, occurrence of gastritis and gastric ulcers and gastric inflammation. Its potency as anti-ulcer agent is comparable to that of various PPIs. [139]
The ethanolic extract of E. alba administered orally at doses of 50, 100 and 200 mg/kg body weight twice a day exhibits antiulcer activity in several peptic ulcer rat-models in a dose dependent manner. The antisecretary activity of the extract was evident by reduction in volume of gastric juice, total acid output and increase in gastric pH. [140]

To evaluate anti-peptic ulcer efficacy of E. alba, by administering aspirin or ethanol peptic ulcer was induced in Sprague Dawley rats. Administration of methanolic extract of E. alba prior to induction of peptic ulcer, protected the animals against drug-induced peptic ulcer. This activity of the extract of E. alba was comparable to proton pump inhibiting drug rabaprazole. [141]

Hepatoprotective Activity
CCl4 inflicts insult on the liver. The parenchyma undergoes fatty degeneration culminating into cirrhosis and death. CCl4inhibits the hepatic microsomal drug metabolizing enzymes. In experimental animals the ethanol-water (1:1) extract of E. albasignificantly restored the loss of hepatic lysosomal acid phosphatase and alkaline phosphatase caused by CCl4. [142]
In another study the ethanolic extract of leaves of E. alba and seeds of Piper longum (50mg/kg body weight) was administered orally once a day for fourteen days. All the biochemical markers of the liver function were restored to normal levels. The triterpenoid eclabasaponin fraction contained in the methanolic extract of the leaves restored the liver functions to normal levels. The coumestan fraction and triterpenoidal saponin fraction contained in the chloroform extract of roots very significantly reduced CCL4 induced increase in lysosomal enzyme levels in the blood. [143]
Administration of fresh leaf powder of E. alba at the dose of 500mg/kg bodyweight to rats exhibited a significant hepatoprotective activity against paracetamol-induced hepatotoxicity [144]
In albino rats, the ethanol extract of the whole plant of E. alba exhibits hepatoprotective activity against alcohol-induced liver dmage. Moreover the toxic effects of alcohol can be reversed with co-administration of the ethanol extract of the whole plant. E. alba not only normalizes the biochemical markers of liver injury but also reverses the histopathological changes that occur in the liver after the alcoholic liver disease. [145] 
The hepatoprotective effect of E. alba is attributed to the coumestans (wedelolactone and demethylwedelolactone) [146]
In another Indian study Eclipta alba extract and its isolates;  wedelolactone, luteolin and apigenin exhibited anti HCV activity in vitro and in cell culture system. It was further established that the inhibition of HCV replication in cell culture system was via inhibition of HCV replicase activity in the cell. Researchers suggest, standardized extract of Eclipta alba or its isolates can be used as an alternative and/or complimentary treatment against HCV. [147], [148]
Two studies by Dixit and Achar (1979 and 1981) reported efficacy of E. alba for the treatment of jaundice due to viral hepatitis in adults and in children. [149], [150]    
In my opinion E. alba, Piper longum (Pippalee), Picrorhiza kurroa (Kutakee), Phyllanthus niruri / Phyllanthus amarus(Bhoomyaamalakee, Bhui Aamalaa)  and many other hepatoprotective drugs from plant kingdom should be tried either singly or in combinations in patients with hepatitis B and C infections, alcoholic liver disease, NASH, cirrhosis of the liver etc.
The other species E. prostrata is also hepatoprotectant. In rats the alcoholic extract of aerial parts of this plant (Dose: 62.5 to 500mg/kg) restored the liver functions to normal following CCl4 induced liver injury. When administered orally or intraperitoneally the extract did not show toxicity. In mice the lethal dose was greater than 2g/kg. 
Stigmasterol and alpha-terthenyl are hepatoprotectants.
Researchers from Chandigarh, India have reported Eclipta alba to be effective in converting the HbsAg positive patients to HbsAg negative. [151], [152]
Wedelolactone present in E. alba exhibits antifibrotic effect on human hepatic stellate cell line LX-2. Hepatic stellate cells (HSC) are a major fibrogenic cell type that contributes to collagen accumulation during chronic liver disease which subsequently culminates into liver fibrosis. By inhibiting the activation of HSCs wedelolactone prevents the development of liver cirrhosis. [153]
Antidiabetic Activity
Oral administration of suspension of leaf of E. alba at doses of 2 and 4 g/kg bodyweight to alloxan-induced diabetic rats resulted in significant reduction in blood glucose from 372mg/dl to 117mg/dl and glycosylated hemoglobin, Hb A(1)c;
a decrease in the activities of glucose-6 phosphatase and fructose 1,6-bisphosphatase, and increase in the activity of liver hexokinase. These activities control diabetes and diabetes-related complications
Similar results were observed in streptozotocin (STZ)-induced diabetic rats by other researchers. [154], [155]
Actions on Metabolism
Adipocytes arise from multipotent adipogenic stem cells in the vascular stroma of adipose tissue and remote stem cells of other organs. Adipocyte hyperplasis is associated with obesity [156]
Wedelolactone has been observed to inhibit the adipogenic differentiation of human adipose tissue-derived mesenchymal stem cells. [157]
The alcoholic extract of whole plant of E. prostrata, in albino rats reduces elevated serum cholesterol, LDL and triglyceride. Needless to say the response is dose dependent. Like E. alba, E. prostrata is rich in wedelolactone which is effective in lowering the lipids. Ecliptalbine and verazine show lipid lowering activity.
The aqueous extract of the leaf of E. alba at the dose of 200mg/kg body weight administered orally to rats significantly reduced total cholesterol, triglycerides and increased high density lipoprotein cholesterol levels. [158], [159]
Actions on Urinary System
The powder of dried leaves of E. alba (3g/day) is a very good diuretic. When used at this dose the urine volume increased by 34% and excretion of urinary sodium increased by 24%. [160]
Actions on Male Reproductive System
In an experimental study male Wister rats were fed orally with boric acid at a dose of 350mg/kg bodyweight for 30 days. From 15 days onwards the toxic effects on testis, kidney and liver were evident. After 30 days the damage to testis was complete. After 30 days, the hydroalcoholic extract of Eclipta alba was administered orally to the rats at a dose of 500mg/kg body weight for 60 days. In the rats treated with the plant extract there was a complete reversal of toxicity. The levels of testosterone, estrogen and FSH returned to normal. The fertility was restored and the altered tissue morphology showed significant signs of recovery. However the mechanism of action of E. alba is not clear and needs further study. [161]
Anti-Tumor Activity
By inducing apoptosis, wedelolactone present in E. alba, kills both androgen-sensitive and androgen-independent prostate cancer cells [162]
Methanolic extract of E. alba exhibited anticancer activity against Ehrlich Ascites Carcinoma in Swiss albino mice. [163]
Recently a new saponin, Dasyscyphin-C is isolated from Eclipta prostrata. It has anticancer activity against human cervical carcinoma [164]
The hydro-alcoholic extract of E. alba inhibits the cell proliferation in a dose-dependent manner in HepG2, A498 and C6 glioma cells. The extract downregulates nuclear factor κB (NFκB) and damages the DNA of malignant cells [165]
The hydro-alcoholic extract of the plant (E. alba) demonstrated antiproliferative activities in multi-drug resistant hepatocellular carcinoma cell line [166] 
Juice obtained from E. alba inhibits the migration of liver, lung and breast cancer cells. Thus E. alba plant extract prevents cancer metastasis
The juice also demonstrates anti-angiogenic activity [167]
The methanol extract of E. alba has been shown to inhibit the growth of colonic cancer cells. [168], [169]
Culinary uses
Not used routinely. In some countries it is included in diet to prevent breast and prostate cancer.

Usages in Ayurveda
In Ayurveda the plant is considered a Rasaayana (Adaptogen) for rejuvenation of hair, teeth, bones, memory, sight, hearing and body systems imparting longevity.
It is used to promote deep sleep.
It is used for the hair care and to improve complexion.
It is used to relieve gastralgia, nausea and vomiting. 
The Roots are used as emetic and purgative.
It is strongly recommended for the treatment of jaundice, ascites and enlarged spleen (probably due to portal hypertension and not due to any other cause). It is especially rejuvenating for hair, skin and teeth. According to Ayurveda the liver is the controller of hair, nails, skin and teeth. Hence by improving the liver functions Bhringraj acts as rejuvenator for these tissues.
Bhringraj improves iron metabolism and improves the quality of the blood.
Acting as appetizer it increases bile flow from the liver into the intestines. [170]
By sedating the nervous system it relieves headache and vertigo.
It reduces BP and edema
It has been used in night blindness and myopia to improve vision.
It is useful in skin disorders and improves complexion. [171]
It is used to relieve dysuria and improve kidney function.
The leaves are used to treat Dysfunctional Uterine Bleeding (DUB) and repeated abortions.
It is used to treat scorpion stings.
Recently nasal instillation (nose drops) of Bhringraj Tailam (Bhringraj Oil) along with administration of Kaasis Bhasma internally has been used to treat premature graying of hair (Palitam, palitham). Vide infra (Additional Information)

Nimba beeja (seeds of Citrus limonum) are macerated with Bhringraj juice and decoction of wood of Asana (Pterocarpus marsupium) tree to make paste. The paste is cooked in Sesame oil. Few drops of this oil are instilled in each nostril. During the treatment the patient consumes rice and milk as staple diet. This cures premature graying of hair in men.
Chakradatta:
To relieve gastritis, hyperacidity and vomiting mix Hareetakee (Terminalia chebula) powder, Bhringraj and old jiggery and consume small pills frequently.
For healthy hair- Cook Sesame oil with Bhringraj juice, paste of triphalaa, Neelotpala (Nymphaea stellata Wild), Saariwaa (Hemidesmus indicus L.) and slag of iron (partially vitreous by-product of smelting iron ore). Use this hair oil daily. This hair oil makes the hair curled, dense and firm. [173]
