Daaru-Haridraa (Berberis aristata)
Daaru-Haridraa (Berberis aristata)
Daaru-Haridraa AKA Barberry in the West is a common garden bush. Daaru- Haridra (Berberis aristata) occupied an important place in Ayurveda. In Ayurveda its pleiotropic properties were harnessed to treat a variety of ailments. In the Middle East, Barberry (Berberis aristata) attained the status of “medicine” in ancient times, since Egyptian pharaohs and queens used Barberry with fennel seeds to prevent and ward off the plague. In Egypt, it is still in vogue for fevers associated with pestilence. In the medieval times, it was recommended for liver and gallbladder disorders. For many years, in Europe and America, it has been used for the treatment of fever, disorders of the stomach, loss of appetite, diarrhea and to improve ‘energy’ and well being. In Russia, it has been used for inflammations and high arterial tension. In Italy, it is known as “Holy Thorn”. The Italians believe that the plant is wrapped in Christ’s thorns he wore around his skull. Early physicians thought that the yellow wood of Barberry could allay jaundice. This belief was based on the philosophy of the doctrine of signatures. Native American Indians used Daaru-Haridraa in cases of general debility and as an appetizer. The colonists used the root of the herb as bitter tonic. In traditional folk medicine, Barberry is used to improve appetite, to treat fever, diarrhea and to increase vitality. . 
The philosophy of the “Doctrine of Signatures”, dating from the time of Dioscurides and Galen, states that, herbs that resemble various parts of the body can be used to treat ailments of that part of the body. A theological justification offered by botanists like William Coles for this philosophy, was that God would have wanted to show men what plants would be useful for treating ailments of various parts of the body. “It was reasoned that the Almighty must have set his sign upon the various means of curing disease which he provided.” Since the wood of the tree Daaru-Haridraa AKA Barberry (Berberis aristata) is yellow in color, early physicians used it to treat jaundice. (Daaru stands for wood and Haridraa for yellow color resembling the color of Haridraa i. e. Turmeric)
There is no scientific evidence to prove the “Doctrine of Signatures”. Scientists therefore see the doctrine as a superstition.

Berberrine is a strongly yellow colored, crystalline alkaloid. Under UV light berberine shows a strong yellow fluorescence. Berberine is a quaternary ammonium salt from protoberberine group of isoquinoline alkaloids. 
Phytopharmacology of berberine is also described in detail in the chapter on Guduchee (T. cordifolia)
Pharmacodynamics/ Pharmacokinetics of Berberine
No pharmacokinetic data on animal studies about Daaruharidraa (Berberis aristata) is available. However, in humans, oral administration of 1.2 g of berberine significantly delays small intestinal transit time. 
Absorption: Eight hours after administration of 500 mg/ kg of berberine to infant rabbits, the blood concentration was 0.8 microgram/ml. Berberine can be absorbed through skin 
Metabolism: Peak concentration of berberine reaches after 12 hours in the muscles and liver.
Distribution: In rats, after the oral dose of 0.1g/kg maximum serum concentration is 0.083mcg/ml and time to maximum concentration is 2.4 hours. The blood levels plateau at 4 to 24 hours. 
Excretion: Berberine is excreted through urine and feces. The elimination half-life of berberine in rats is between 5 and 6 hours, peak urinary excretion is between 12 and 24 hours while peak fecal excretion is seen after 48 hours. , 
Anti-inflammatory activity of Berberine
Berberine inhibits activator protein-1activity which is essential for inflammation.
Berberine inhibits cyclo-oxygenase-2 (COX-2) enzyme.
Berberine significantly inhibits interleukin-1 (IL-1) and interleukin-8 (IL-8) and decreases leukotriene formation.
Berberine significantly decreases leukotriene formation and monocyte production. It inhibits PGE2 generation by monocytes.
By decreasing vascular permeability, berberine inhibits inflammatory edema. 
Anti-oxidant activity of Berberine
Berberine has anti-oxidant effects in the riboflavin system. In xanthine oxidase system its anti-oxidant effect is greater than that of vitamin E. It exhibits anti-oxidant activity via inhibition of lipooxygenase and lipid peroxidation. 
Immunomodulating activity of Berberine
Berberine shows significant inhibition of mitogen induced lymphocyte transformation.
Berberine inhibits neutrophil adherence and chemotaxis. 
Anti-microbial activity of Berberine
Berberine has significant anti-microbial activity against Gram positive and Gram negative bacteria and fungi. 
In vivo study with white mice berberine showed antibacterial activity against Streptococcus pneumoniae. 
In vitro (in mice) methyl extract of berberine demonstrated ‘cidal’ activity against T. vaginalis, G. lamblia, and E. histolytica. 
Berberine sulphate is bactericidal against Vibrio cholera at 35 mcg/ml concentration, against Staphylococcus aureus at 50mcg/ml concentration and Streptococcus pyogenes at 30mcg/mL concentration. Berberine also shows anti-bacterial activity against Escherichia coli, Shigella dysenteriae, Salmonella paratyphi and various Klebsiella species. Berberine sulphate also exhibits antimicrobial activity against Gram-positive, Gram-negative bacteria, fungi and protozoal organisms through the inhibition of RNA and protein synthesis. , 
In an in vitro study, berberine was shown to suppress the growth of Helicobacter pylori in a dose dependant manner. 
Actions of Berberine on Nervous System
To evaluate cholinergic activity of berberine, in one study, berberine was administered to rats at the dose of 0.1 g/kg and 0.5/kg for 14 days. This treatment improved scopolamine-induced amnesia in rats. This effect was augmented by physostigmine and neostygmine. 
Berberine has muscle relaxant effect on smooth muscles. In one study at the dose of 20mcg/kg body weight berberine sulphate blocked the response of ileum, trachea and rectal muscles to acetylcholine. 
In animal study berberine sulphate produced sedation and potentiated the sedative effects of pentobarbitone. 
In mice berberine has shown to lower rectal temperature, reduce spontaneous motor activity and prolong hexobarbitone-induced sleeping time. 
Actionsons of Berberine on Endocrine System
In an animal study berberine has been shown to inhibit parathyroid hormone-stimulated bone resorption. At doses of 30-50mg/kg/day berberine prevents the decrease in bone mineral density of lumbar vertebrae in oophorectomised rats and induces apoptosis of osteoclastic cells. 
Actions of Berberine on GI system:
Given orally to mice at doses of 0.06 mg to 20 mg/kg daily decreases the frequency of purging by delaying intestinal motility. In mice at doses of 40 and 80 mg/kg bodyweight berberine sulphate decreases the occurrence of purging induced by castor oil. , 
By delaying intestinal motility berberine shows anti-diarrheal activity. Berberine significantly inhibited the actions of Vibrio cholera enterotoxin and E. coli enterotoxin when administered before or up to four hours after toxin injection.
In experimental studies berberine reduced the secretion of water, sodium, chloride and bicarbonate induced by cholera-toxin in rat ilea. It also inhibited the secretary response to E. coli enterotoxin.
Results suggest that the antidiarrheal property of berberine is mediated via its ability to delay the small intestinal transit. , , 
Actions of berberine on hepato-biliary system:
Berberine increases the secretion of bilirubin in rats with hyperbilirubinemia but this effect diminishes on continued administration of berberine. 
However a recent study shows that berberine displaces bilirubin from albumin in both in vitro and in animal studies, resulting in an increase in serum total and direct bilirubin concentrations. 
In an in vitro study, berberine has been shown to be hepatoprotective when administered twice a day for two days before receiving toxic doses of paracetamol. 
CCl4 is a known hepatotoxic agent. The CCl4 toxicity is manifested by elevation of liver enzymes and histological changes in the hepatic tissue. On administration of berberine the elevated levels of liver enzymes come to normal and histological study shows reversal of the damage. Berberine at the dose 10mg/kg markedly attenuates the expression of TNF-α, COX-2 and iNOS. Thus berberine inhibits the inflammatory response of CCl4 toxicity in the liver. 
At doses of 2mg/kg intramuscularly or 3mg/kg orally thrice a day berberine prevents the development of amoebic hepatitis in hamsters. 
For in vitro study of anti-hepatitis B activity of berberine, HepG2.2.15 cell model was selected. The result of the study revealed that berberine can inhibit hepatitis B virus in vitro. The antiviral effect may be related to AP-1 up-regulation and CHOP down regulation. Further study is necessary to confirm the mechanism of anti-hepatitis B activity of berberine. However in Feb. 2010, the researchers have applied for patent for this work. 
On Feb 20, 2013, the application for a patent (Code No C12) was rejected. 
The precise mechanism of development of non alcoholic fatty liver disease (NAFLD) is not understood. Obesity, dyslipidemia, insulin resistance, deposition of intra hepatic fat and inflammation are crucial players in the process of NAFLD. NAFLD is the hepatic manifestation of obesity and metabolic syndrome.
By correcting hyperlipidemia, berberine strongly reduces storage of fat in the liver. Treatment with berberine for sixteen weeks alleviates hepatic steatosis. Berberine also reduces hyperlipidemia in statin-intolerant subjects. Diabetes predisposes to steatosis. Berberine reduces the insulin resistance, controls diabetes, and prevents hepatic steatosis. Further berberine prevents the development of obesity, insulin resiastance and reverts hypertriglycerinemia to normal levels. Thus berberine prevents and arrests the progression of fatty degeneration of the liver. Investigations show that berberine supplement reduces alanine and aspertate transaminases in type 2 diabetes, indicating the restoration of liver function. Furthermore, berberine has been shown to reduce liver necrosis in NAFLD and in steatosis due to hepatitis C infection. The recent literature suggests that berberine may be integrated into glucose and lipid regulation for combating NAFLD and metabolic syndrome. 
Actions of berberine on Cardiovascular System (CVS)
Berberine extract inhibits adrenalin-induced aortic contraction, improves the left ventricular function in dogs with failing heart, decreases the peripheral resistance, increases significantly the cardiac output and ejection fraction. It also exhibits anti-arrhythmic activity and restores normal sinus rhythm. 
The bolus dose of 1mg/kg of berberine sulfate injection administered to rats one minute after undergoing coronary artery occlusion significantly reduced early mortality from ventricular fibrillation. 
Berberine sulfate decreases the blood pressure in experimental animals. The effect is dose-dependent. This hypotension is not inhibited by atropine, mepyramine maleate, propranolol and phenoxybenzamine. 
In rats at 20mg/kg berberine inhibits platelet-activating factor. It inhibits platelet aggregation caused by ADP, arachidonic acid and collagen. 
Antineoplastic activity of berberine
Berberine inhibits etoposide and campothecin induced DNA fragmentation and apoptosis of thymocytes.
Berberine inhibits activator protein-1 activity which is essential for carcinogenesis.

Isotetrandrine can enhance the cytotoxicity of doxorubicin. Researchers suggest that isotetrandrine might become a candidate for multidrug resistant cancers. 
Some Testiminials from Modern research
Berberine is the prime important pharmacologically active molecule in all the species of Berberis. Hence the pharmacology of Daaruharidraa (Berberis aristata) is the pharmacology of berberine. It is described in detail above. However in the experimental studies where all parts of the herb are used to observe the pharmacological actions are described here.
Berberis aristata protects the liver from CCl4 toxicity. This activity is mediated through inhibition of microsomal drug metabolizing enzyme. 
Often Berberis vulgaris and Berberis aristata are used as synonyms for Barberry. Berberis vulgaris exhibits anti-hepatitis C activity. This effect is attributed to immunostimulant potential as it enhances the phagocytic activity of mononuclear cells in the blood. 
To evaluate anti-cirrhotic activity of Daaruharidraa (Berberis aristata), cirrhosis was induced in rats by using Dimethylnitrosamine. The cirrhosis was proved by elevated liver enzymes, hematological abnormalities and histological changes. The oral administration of Ethanolic Extract of Berberis aristata (EEBA) and Aqueous Extract of Berberis aristata (AEBA) at the dose of 200mg/kg, decreased the size of cirrhotic nodules, improved the biochemical and hematological parameters. These results were compared with the dose of 100mg/kg of silymarin, the standard drug used as a hepatoprotectant. The results showed that EEBA and AEBA exhibit anti-cirrhosis activity similar to silymarin. However EEBA is more effective than AEBA.
In one study Earlich-Ascites-Carcinoma was induced in Swiss albino mice by injecting 106 cell/ml of tumor cell suspension. EEBA and AEBA were used to treat these animals. Daaruharidraa (Berberis aristata) improved the general condition of the animals. The animals gained weight. The survival of the animals was prolonged. But these results were inferior to the anti-tumor effect of 3.5 mg/kg dose of cisplatin. Of the two extracts of Daaruharidraa (Berberis aristata), EEBA was more effective. 
The fruits are eaten as dessert. They are succulent, sweet and contain nutrients and antioxidants. The roots and fruits are used to prepare alcoholic drinks. The acidic flower buds are made into sauce.

LD50 value of berberine in mice was found to be 25.3 mg/kg I. P. But in human beings berberine is free from any serious toxicity.
In larger doses B. aristata can be toxic giving rise to symptoms such as vomiting, severe diarrhea, excessive sweating, lethargy, nose bleed, severe hypotension, skin and eye irritation and urinary problems. In such cases the drug or any preparations containing B. aristata should be withdrawn.
Standardized extracts of the plant can cause stomach upset and should not be used for more than two weeks at a time.
It is contraindicated for infants and young children. In pregnant women it can cause uterine contractions and in first trimester can cause abortion. It is contraindicated during lactation.
It is toxic to growing sperm cells. Hence males of reproductive age group should not use it as it may contribute to sterility.
It interacts with doxycycline, tetracycline. Interactions with other antibiotics should also be borne in mind.
