Guduchee (Tinospora cordifolia)
Guduchee (Tinospora cordifolia)
From Indian mythology to Ayurveda and modern medicine Guduchee (Tinospora cordifolia) is extolled as a remedy par excellence for the treatment of many diseases especially those of the liver.
It has a noble place in the epic Raamaayana: During the war between Raama and Raawana, to resurrect the army of Raama, Lord Indra gave “amrita” i. e. “divine nectar” to Raama’s army. The Guduchee plant grew from the few drops of ‘nectar’ that fell on the ground. 
From fever to cancer the herb protects the body from diseases; hence the epithet Guduchee (the one that protects, the one that acts as a savior from diseases). Another synonym of the plant is Madhuparnee (the one whose leaves are full of nectar). When we cut a fresh spring from Guduchee tree and hang it from a cord in the air; it will continue to grow without any visible or perceptible nutritional support. It gains its ‘life energy’ from environment. Hence in Sanskrit it is called ‘Amritaa’ meaning immortal or imperishable! As the plant confers vitality, vigor and youthful longevity or imparts immortality on any one who consumes it, the plant is called ‘Amritaa’ (divine nectar of longevity). The other Sanskrit epithets used for Guduchee are: Chhinnaruhaa/Chhinnodbhawaa (the plant that grows from the cut side), Watsadini (eaten by grazing animals), Rasaayanaa (the plant possessing capacity to improve Rasa Dhaatu), Chakraangi/Chakralakshnaa (having wheel-like appearance), Jwaranaashee/Jwaraari (potent antipyretic), Wayastha (age-stabilizer, prevents ageing), Amritasambhawaa (ambrosia) and Bhishakpriyaa (favorite of physicians). 
Guduchee has been described as “one which protects the body”. The word Amritaa is derived from ancient Hindu scriptures where Amritaa was used to bring the dead back to life and keep gods from growing ill and old. It for these reasons Guduchee is also referred to as “nectar of immortality” and “heavenly elixir” 
The name of its genus Tinospora is derived from the Greek teino which means “to stretch like a bow” and spora which means “seed”. Its leaves are heart shaped; hence the name of the species is cordifolia. 
In Ayurveda Guduchee has long been used as a tonic, vitalizer and as a drug to treat many ailments. Along with many beneficial properties of Guduchee, the noted Ayurvedic surgeon Sushruta described it as ‘shukra-shodhana’ meaning sperm purifier. Its property of imparting vigor and vitality and its ‘shukra-shodhana’ ability are probably misconstrued in the ‘Kaama-Sootra’ as ‘aphrodisiac’. In his translation of the classic text ‘Kaama-Sootra’ in 1883, Sir Richard Burton writes (free rendition by me): If the juice of fennel (English: Anise, Marathi: Badeeshepa) and milk are mixed with equal quantities of ghee, honey, sugar and liquorice (Glycyrrhiza glabra), the mixture acts like nectar and is said to be sacred, provocative of sexual vigor and stabilizer of age and life. SS Richard Montgomery Matter refers to Sir Richard Burton’s aphrodisiac formula: guduchi (Tinospora cordifolia), pippali-long pepper (Piper longum) and licorice (Glycyrrhiza glabra) boiled in milk, honey and sugar has aphrodisiac effect.
Kamasutra-SS Richard Montgomery Matter
However Ayurvedic sources express mixed opinion. Some mention it, some don’t.
George Playfair’s translation of the Indian Materia Medica, Taleef Shereef, 1833 does mention Guduchee but certainly not as being aphrodisiac!

Guduchee (T. cordifolia) is a large, deciduous, extensively spreading, perennial herbaceous vine of weak and fleshy stem found throughout India. T. cordifolia is a big twining glabrous climber which generally climbs with several elongated twining branches on large trees preferring the support of mango and neem trees.
Roots are tuberous, long thread like, aerial; arise from branches, often growing on neem or mango trees.
Bark is thin, succulent, creamy white to grey in color, with deep clefts spotted with lenticels. (A lenticel is an opening that allows gaseous exchange between air and the inner tissues of a plant)
Stem succulent, fleshy, twining, 0.5 to 5 cm in diameter, green when young, with smooth surface and swelling at nodes; older ones are brown in color with warty protuberances.
Branches are grey-green, up to 40 mm in diameter, becoming brown with age
Leaves are heart-shaped, smooth, simple, alternate, exstipulate; petiole up to 15 long, roundish, pulvinate (having a swelling), both at the base and apex with the basal one longer and twisted partially and half way around. Lamina broadly ovate or ovate-cordate, 10-20 cm long, 8-15 cm broad, 7 nerved and deeply cordate at base, membranous, pubescent above, whitish tomentose with a prominent reticulum beneath.
Flowers are small, leafless, yellowish-greenish in color, growing in lax axillary, terminal racemes (Marathee: Pushpamanjiree) emerge from nodes on old wood in spring. They are unisexual (male and female flowers are formed on different plants). Male flowers clustered, female usually solitary. Sepals six, free in two series of three each, the outer ones are smaller than the inner. Petals six, free, smaller than sepals obovate and membranous.
Fruits are drupes, pea like, aggregate of 1-3, up to 10 mm in diameter, smooth, oval, glossy, succulent, fleshy, on thick stalk, single seeded, turning scarlet or orange-red when ripe, up to 10 mm in diameter.
Seeds are curved, pea-sized.
Root: The aerial root is characterized by tetra- arch to penta- arch structure. The cortex has outer thick walled zone representing the velamen (a spongy epidermis that covers the roots of some plants) and inner parenchymatous zone containing secretory canals. Starch is present throughout the parenchyma of the aerial root. The starch grains are elliptical in shape, mostly simple but sometimes as compound grains of 2 to 5 components, with faintly marked concentric striations and central hilum appearing like a point.
Stem: Stem is characterized by the presence of bicollateral vascular bundles surrounded by pericycle fibers. The cork arises in the sub-epidermal layers giving rise to 2-3 layers of cork. Starch is present throughout the parenchyma of the stem.
(Note: The bicollateral vascular bundle consists of two patches of phloem, two strips of cambium and one patch of xylem at the center. It is confined to certain dicot stems only) 
Leaf: In transverse section the petiole is more or less circular in outline. No trichomes (fine outgrowths or appendages) found. The cross section shows a single layered epidermis and a wide zone of cortex composed of 3-4 layers of endodermis. The vascular bundles consist of radial rows of xylem on the inner side and a few rows of cambium cells on the outer side followed by phloem. The mid-rib is more or less circular in outline and palisade does not extend over the stellar tissue. The cross section of lamina shows a dorsiventral structure with its mesophyll differentiated into palisade and spongy tissue. The mesophyll is clearly differentiated into a palisade layer made up of one row of thin-walled columnar cells which occupy a little more than half of the width of mesophyll. Glandular hair are present in lower surface only. They are unicellular and somewhat club shaped. The base is surrounded by 4 to 5 epidermal cells. Starch is present throughout the tissue. 
Every part of the plant has medicinal use. In Auyrveda the whole plant is valued.
In Ayurvedic pharmacopoeia the stem is approved because of higher content of alkaloid in it. The traditional preparation ‘Guduchee Sattwa’is obtained from the herb growing with the support of neem (Azadirachta indica). The preparation is said to incorporate the medicinal values of neem. Hence the preparation is bitterer and more efficacious.
According to the class of chemical to which they belong, a large number of chemical compounds isolated from T. cordifolia can be described as:
Berberin, Tembetarine, Magnoflorine, Choline, Tinosporin, Isocolumbine, Palmatine, Tetrahydropalmatine, bitter gilonin, non-glycoside gilonin gilosterol 
18-neoclerodane glucoside, Furanoid-diterpene glucoside, Tinocordiside, Tinocordifolioside, Cordioside, Cordifolioside A to E, Syringin, Syringin-apiosyl glucoside, Palmatosides C and F, Amritoside
Furanolactone, Clerodane derivatives, Tinosporin, Tinosporides and Jateorine
Recently four new clerodane furano diterpene glucosides (amritosides A, B, C and D) have been isolated as their acetates from stems. 
Cordifolide A, a sulfur-containing Clerodane Diterpene Glycoside has been isolated from Tinospora cordifolia. Probably this is responsible for anti-microbial activity of the plant. Cordifolide B and C have also been isolated as a white powder in the form of a mixture that could not be further separated by any chromatographic methods.
Beta Sitosterol, Delta Sitosterol, 20- Beta Hydroxy ecdysterone, Makisterone A, Giloinsterol (Gilosterol)
Nonacosan, Jatrorrhizine, Tinosporidine, Cordifol, Cordifelone, N-Trans-feruloyl Tyramine diacetate, Giloin, Gilonin, Tinosporic acid,
The adaptogenic compounds for which the plant is valued most need a special mention. They are:
Diterpine compounds, Tinosporin, Tinosporides, Berberine, Giloin, Giloinin, Arabinogalactan, Picrotene and bergenin.
A new hypoglycaemic agent was isolated from the plant. It was found to be 1, 2-substituted pyrrolidine. 
The phytochemical analysis of T. cordifolia revealed that alkaloids, flavonoids, tannins, phenols, saponins, glycosides, aminoacids and steroids contained in the plant might be accountable for its antimicrobial potential.

Medowaha Srotas: Adipose system
Eons ago Ayurveda recognized Meda (Fat) as one of the components of Adipose system. Ayurveda also described some functions of Meda. However, for centuries Modern medical science did not recognize adipose tissue as a component of any system. It is only recently we say ‘Fat is not a lump of lard!’
Now according to modern view, Adipose tissue is a complex, metabolic and endocrine organ. It is highly active. The adipose tissue contains adipocytes, connective tissue matrix, nerve tissue, stromal cells, and immune cells. These components function as an integrated unit. Adipose tissue responds to afferent signals from endocrine system and the CNS. It secretes leptin, cytokines, adiponectin, complement components, plasminogen activator inhibitor-1, proteins of the renin-angiotensin system, and resistin. Adipose tissue (system?) is a major site for metabolism of sex steroids and glucocorticoids. Collectively they perform important endocrine functions.
Well! This is not the place to discuss in detail about the ‘Adipose System’. However the author decided to give only an overview necessary for the current context.

When taken internally routinely (daily) Guduchee choorna (powder) can delay aging. Thus Guduchee acts as wayahsthaapak rasaayana (anti aging, age-stabilizer-rejuvenator).
Guduchee improves microcirculation, hence it is recommended for correcting ischemic vascular diseases like PVDs.
Guduchee possesses antiseptic and analgesic properties.
Because of its Snigdha Guna and Madhur Wipaaka, Guduchee is a very good aphrodisiac. 
Guduchee (T.cordifolia) is antipyretic, antiperiodic (a remedy possessing the property of preventing the periodic exacerbations), blood purifier, paandunaashaka (anti-anemic), waataraktahaaraka (anti-gout), daaha prashamana (the one which respites or allays or relieves burning sensation), kushthanaashaka, (anti-leprotic), walee-palita naashaka (arrests and prevents balding), trishaa shaamaka (alleviates and quenches excessive thirst), bitter, appetizer, digestive (digestant), antiemetic, anthelmintic, kaamalaahara (allays jaundice), hepatoprotectant, antitussive, antiasthmatic, hridroganaashaka (relives cardiac disorders), mehanaashaka (antidiabetic), diuretic, balya (tonic, increases strength), wayah-sthaapaka (stabilizes age and prevents aging), adaptogen, rasaayana (rejuvenator), chakshushya (beneficial to eye and useful in ophthalmic disorders), nervine tonic and memory booster ( does it mean prevention of Alzheimer’s disease?), tonic and vitalizer, wrishya (aphrodisiac). The well-ground whole plant paste is applied on fractures.
Maharshi Charaka makes a special mention about it as ‘stanya shodhana’ (the one which purifies breast milk)
Sushruta the noted surgeon mentioned it as ‘shukra shodhana’ (the one which purifies the semen and sperms)
T. cordifolia has anti-inflammatory, antioxidant, immunomodulatory, antipyretic, anti-allergic, anti-leprotic, antispasmodic, antiemetic, cholagogue, hepatoprotective, detoxicating, antiarthritic, adaptogenic, antidiabetic, antimalarial and anti-neoplastic activities. The main target organs for Guduchee are liver, spleen and kidney.
Molecular formula: C6H12O6, HO (C6H10O5)n
It activates the immune system through the activation of macrophages. 
The signaling mechanism of (1, 4)-alpha-D-glucan (RR1) was investigated in macrophages to evaluate its immune-stimulating properties. 
Further study revealed that this activity is mediated via TLR6 signaling, NF kappa B translocation and cytokine production.
Pharmacological actions of AG have been discussed in detail in the chapter on Bhoomyaamalakee (P. amarus)
Molecular formula: C27H44O6
Ecdysteroids are steroids found in invertebrates and plants. In mammals they have protein anabolic effects. Beta Ecdysone has anti-osteoporosis activity. In oophorectomized rats Guduchee (Tinospora cordifolia) was found to increase the thickness of atricular cartilage of the lower end of femur and upper end of tibia and epiphyseal growth plates and trabacular bone in the region of metaphyseal region of tibia. The whole epiphyseal growth plate and its proliferative and hypertrophic zones were also increased. Therefore Guduchee (Tinospora cordifolia) can be used to prevent osteoporosis and osteo-arthritis which explains Guduchee being used as ‘Rasaayana’ in Ayurveda. 
Ecdysteroids have cytotoxic properties. 
The ethanolic extract of stem of Tinospora cordifolia has anti-osteoporotic effect. This effect is attributed to ecdysteroids contained in it. 
Molecular formula: C20H18NO4+
Berberine is strongly yellow in color. Under ultraviolet light it shows a strong yellow fluorescence.
Berberine is considered antibiotic. In combination with 5- methoxyhydnocarpin berberine breaks multidrug resistance of many microorganisms. Berberine inhibits the growth of Staphylococcus aureus. Berberine increases adiponectin expression.
Berberine prevents glucocorticoid induced osteoporosis. 
Berberine is a quaternary ammonium salt. It belongs to protoberberine group of isoquinoline alkaloids. It has pleiotropic properties and actions.
Berberine shows antifungal activity. It is synergistic to fluconazole but is active even against fluconazole resistant Candida albicans.
Berberine is active against Staphylococcus aureus and methycillin resistant Staphylococcus aureus (MRSA).
Berberine is active against trachoma virus. Hence it is used in some eye-drop formulations.
In some centers berberine is an established treatment for leishmaniasis.
Berberine is a very potent anti-inflammatory agent. It inhibits pro-inflammatory cytokines, such as E-selectin.
Berberine is a very potent antioxidant. It restores cellular REDOX balance. Its anti-inflammatory and anti-oxidant properties are beneficial to cardiovascular system (CVS). Berberine reduces elevated levels of total cholesterol, LDL, TG and apolipoprotein B by a mechanism different from that of statins. Berberin acts directly on PCSK9 (Proprotein Convertase Subtilisin Kexin 9) receptor, a natural inhibitor of LDL receptor and not through HMG-Co-A. Therefore berberine does not cause side effects typical to statins. Berberine and plant stanols acting synergistically inhibit cholesterol absorption. Thus berberine aggressively controls dyslipidemia and prevents atherosclerosis. Berberine is also useful in advanced congestive cardiac failure (CCF).
Berberine acts on insulin receptors and stimulates them, inhibits aldose reductase, and like metformin overcomes insulin resistance. Thus berberine is very useful for the treatment of metabolic syndrome.
Berberine reduces hepatic fat content in the liver. It is therefore useful for the treatment of non alcoholic steatohepatitis (NASH). Berberine also prevents proliferation of HSCs (Hepatic Stellate Cells) which are responsible for the development of liver fibrosis.
Berberine ameliorates pro-inflammatory cytokines-induced intestinal epithelial damage. Berberine can be useful in diarrhea, dysentery, chronic colitis and inflammatory bowel disease (IBD).
According to a Chinese report, berberine combined with cyclosporine A (Cs A) could markedly increase the concentration of (Cs A) in the blood. Berberine thus can reduce the dosage of (Cs A), saving the cost of therapy and avoiding the untoward side effects.
Berberine has anti-neoplastic activity. It can suppress leukemia, epidermoid carcinoma, melanoma, oral cancers, cancers of the tongue, GI cancers, hepatoma, pancreatic cancers, genito-urinary cancers, glioblastoma, breast cancer etc.
The mechanism of anti-cancer activity of berberine is nebulous. Various explanations offered are:
1. It inhibits angiogenesis
2. It modulates cyclooxygenase (COX-2), MDR, TNF, IL-6, iNOS, IL-12 etc.
3. It binds and inhibits stress induced mitogen-activated protein kinase activation
4. It induces apoptosis of cancer cells
5. Its anti-inflammatory and anti-oxidant properties prevent carcinogenesis
6. It suppresses NF-kappa B activation induced by various inflammatory agents and carcinogens.
Berberine 300 mg thrice a day taken orally inhibits complications of abdominal radiation (Radiation Induced Acute Intestinal Symptoms). Berberine is a cytostatic agent.
Berberine is antidepressant, neuroprotective in neurodegenerative conditions. Berberine is said to be useful in schizophrenia and Alzheimer’s disease (AD) by antioxidant property and through cholinesterase inhibitory and beta-amyloid pathway.
Recent studies show that, anti-inflammatory and macrophage activation properties of berberine may be useful for the treatment of HIV infection.
It seems that all the pharmacological actions of T. cordifolia are in fact the actions of berberine! 
For more details of pharmacology of berberine refer to my monograph on Daaru-haridraa (Berberis aristata)
The protection offered by T. cordifolia against afflatoxin-induced nephrotoxicity is attributed to the presence of alkaloids such as choline, tinosporin, isocolumbin, palmatine, tetrahydropalmatine and magnoflorine. 
Molecular formula: C20H24NO4
Magnoflorine (Mf) is a quaternary ammonium salt. It is ganglion blocking agent. Some curare-like action has also been noticed. It has practically no effect on the adrenergic system. The hypotensive action of magnoflorine is therefore, mainly associated with ganglionic blockade. 
Tinosporin, Tinosporic acid, Tinosporol, Cordifolioside A and Syringin are immunomodulatory agents.
N-Methyl-2-pyrollidone, N-formylannonain, magnoflorine and tinocordiside enhance phagocytic activity. 
Some testimonials from modern research:
The polysaccharides contained in T. cordifolia show anti-inflammatory activity and enhance phagocytosis in vivo. 
The alcoholic extract of T. cordifolia is effective against acute and subacute inflammations. 
T. cordifolia growing with the support of Neem (Azadirachta indica) is known as Neem Giloe. The water extract of Neem Giloe exhibits much superior anti-inflammatory activity. When given orally and intraperitoneally (50 mg/100gram of bodyweight) it significantly inhibited in mice the acute inflammation induced by carrageenan. It also significantly inhibits antibody formation by ‘typhoid H’ antigen. 
This effect is probably because of synergism with chemicals derived from Neem. 
In an animal model, aqueous extract of T. cordifolia was used to treat cotton pellet granuloma and formalin induced arthritis. The extract produced a significant anti-inflammatory activity which was comparable with indomethacin. The extract was effective in both acute and sub acute inflammations. T. cordifolia was more effective than acetylsalicylic acid in acute inflammation. But in subacute inflammation T. cordifolia was found to be inferior to phenylbutazone. 
A compound preparation ‘Rumalaya’by Himalaya Pharmaceuticals (Disclaimer: I have no financial interest) containing T. cordifolia was reported to significantly reduce pain in patients suffering from rheumatoid arthritis. 
In vitro, extract of T. cordifolia inhibits the lipid peroxidation and super oxide and hydroxyl radicals. To achieve 50 % inhibition the concentration needed was 6mg and 12.5 mg/ ml respectively. At 25mg/kg body weight for 10 days the extract also ameliorated the toxicity of cyclophosphamide. These effects are attributed to antioxidant property of T. cordifolia. 
AG isolated from T. cordifolia showed good protection against gamma-ray induced damage. This is attributed to antioxidant and free radical scavenging activity of AG. 
Oral administration of alcoholic extract of the root of T. cordifolia at 100mg/kg for six weeks to diabetic rats reinstates the depleted levels of glutathione in the liver and kidney; thus protecting these organs from oxidative stress injury. 
During and after ischemia and hypoxia of the brain, free radical insult leads to necrosis and brain cell death. Antioxidant activity of T. cordifolia counters these insults and exhibits neuroprotective activity. 
Metal chelating and free radical scavenging properties of T. cordifolia show radioprotective effect. 
In some experimental studies on mice, by modulating the proinflammatory cytokines; G1-4A, a polysaccharide from T. cordifolia protected them against septic shock. 
In some experimental studies on Swiss Albino mice of either sex weighing between 18 and 20 grams; pretreated with T. cordifolia, Thatte UM, Kulkarni MR, Dahanukar SA, injected intraperitoteally, 108 E. coli to induce peritonitis. These animals showed marked bacterial clearance and phagocytic activity against the bacteria as well. T. cordifolia also prevented the development of sepsis. 
Syringin and Cordiol contained in T. cordifolia inhibited immunohemolysis of antibody coated sheep RBCs by guinea pig serum. These compounds also increased Ig G in the serum. However the humoral and cell mediated immunity was dose dependent. Cordoside, Cordiofolioside A and Cordiol contained in the plant also activated macrophages. 
In some studies the water and ethanolic extract of the stem of T. cordifolia was found to inhibit the cyclophosphamide induced immunosuppression 
In summary one can say T. cordifolia can build up specific and nonspecific immunity against many diseases.
The alcoholic extract of the stem shows activity against E. coli. Active principles identified from the plant extract were found to inhibit in vitro the growth of Mycobacterium tuberculosis. 
The plant extract showed in vitro to inactivate Hepatitis B surface antigen. 
Dr. Nirmala Rege HOD, Dept. Pharma and Therapeutics and Ayurveda, G. S. Medical College, Mumbai, India is of the opinion that T. cordifolia is superior to P. niruri in this regard.
In a clinical trial at Regional Research Institute (Ayurveda) Jaipur, India; 20 patients of infective hepatitis (viral hepatitis, type of viruses not mentioned) were treated with tablets (500mg per tablet) prepared from stem of T. cordifolia. Each patient received 500mg tablet with water three times a day for four weeks. Fifteen patients were cured and five patients improved. 
T. cordifolia stimulates the regeneration of hepatic tissue, normalizes the hepatic enzymes and prevents the liver fibrosis.
In experimental studies on mature albino rats, extract of T. cordifolia protected the animals from CCl4 insult. This effect was attributed to hepatoprotective and immunomodulatory properties of T. cordifolia. 
In chronic liver disease Kupffer cells are damaged as indicated by suppressed Kupffer cell function. T. cordifolia improves the cell function and may even normalize it. 
The antituberculosis treatment after 3 months can induce liver damage as is evident by altered liver enzymes and histological changes of liver necrosis. However administration of 100mg/kg of T. cordifolia showed reduction of liver damage, while administration of 300mg/kg of Phyllanthus emblica prevented the liver damage.
Some researchers also tried curcumin from Curcuma longa to protect the liver from the hepatotoxicity caused by anti-tubercular drugs. , 
In Jammu, Thailand and Philippines T. cordifolia, T. crispa and T. rumphii Boerl are used as hepatoprotectants against many toxins. Recent research has shown that a combination of Turmeric extract (Curcuma longa) and Guduchee extract (T. cordifolia) offers better hepatoprotection than T. cordifolia alone to counter the side effects of anti-tubercular drugs. 
Extrahepatic obstructive jaundice is associated with immunosupression, deranged hepatic function and sepsis. This may mar the surgical outcome. Addition of T. cordifolia 16 mg/kg/day orally to conventional management (i. e. biliary drainage, antibiotics, vitamin K etc.) improved surgical outcome by boosting host defenses. 
Extracts of T. cordifolia were useful for the treatment of Hepatitis B and E. The extracts also showed in vitro activity against these viruses inactivating them in 48 to 72 hours. 
Berberine contained in T. Cordifolia reduces hepatic fat content in rats of NASH or NAFLD. Berberine also prevents proliferation of hepatic stellate cells (HSCs), which are central for the development of fibrosis during liver injury. 
Guduchee shows anti HBV, anti HCV activity, activity against obesity and NASH. These activities are due to berberine. The pharmacology of berberine has been discussed in detail in the chapter on Daaru-haridraa (Berberis aristata)
The fruit of the plant has a great capacity to absorb oxygen free radicals. Hence it should be included in daily dishes.
