HP-1 a herbal formulation comprising of Phyllanthus niruri and extracts of Terminalia belerica, Terminalia chebula, Phyllanthus emblica and Tinospora cordifolia has been evaluated for hepatoprotective activity against carbon tetrachloride (CCl4) induced toxicity. Results show that HP-1 reversed the leakage of lactate dehydrogenase (LDH) and glutamate pyruvate transaminase (GPT) and prevented the depletion of glutathione (GSH) levels in a primary monolayer culture of rat hepatocytes (in vitro).
Experimental study was conducted to evaluate the hepato- and renoprotective effect of silymarin and Terminalia chebula against experimentally-induced acetaminophen (APAP) toxicity in rats. Oral administration of APAP @ 500 mg/kg for 1 to 3 days to all the four groups (six rats in each) resulted in significant elevation of serum triglycerides, total cholesterol, blood urea nitrogen, serum creatinine, and aspartate transaminase activity. Post-treatment with silymarin @ 25 mg/kg and T.

The tannoid principles of the fruits of the plant Emblica officinalis Gaertn comprising of emblicanin A. emblicanin B, punigluconin and pedunculagin, have been reported to exhibit antioxidant activity in vitro and in vivo.
Herbal medicines have been used in the treatment of liver diseases for a long time. A number of herbal preparations are available in the market. This article reviews four commonly used herbal preparations: (1) Phyllanthus, (2) Silybum marianum (milk thistle), (3) glycyrrhizin (licorice root extract), and (4) Liv 52 (mixture of herbs).
Terminalia belerica Roxb. is one of the oldest medicinal herb of India, is an ingredient of Indian Ayurvedic drug 'triphala' used for the treatment of digestion and liver disorders. Present study is aimed to evaluate the protective effect of Terminalia belerica fruit extract and its active principle, gallic acid (3,4,5-trihydroxybenzoic acid) at different doses against carbon tetrachloride intoxication. Toxicant caused significant increase in the activities of serum transaminases and serum alkaline phosphatase.

Lampito mauritii, an earthworm widely used in Siddha as well as Ayurveda, has been reported to have anti-inflammatory, anti-ulceral and anti-oxidative properties. The present investigation shows its hepatoprotective role. Whole tissue extract of Lampito mauritii protect the paracetamol (2 g/kg body weight. p.o.) induced liver damage rat as a dose dependent manner (100, 200 and 300 mg/kg body weight p.o.) by significantly (P < 0.05) decreasing the hepatic marker enzymes--aspartate transaminase, alanine transaminase and alkaline phosphatase similar to silymarin (150 mg/kg b.w. p.o.).
ETHNOPHARMACOLOGICAL RELEVANCE: Different parts of the plant Trichosanthes cucumerina Var cucumerina L. (cucurbitaceae) are used to treat liver disorders, traditionally. It is one among the constituents in various Ayurvedic formulations used for the treatment of liver disorders and other diseases. AIMS OF STUDY: The aim of the present study is to evaluate the protective effect of Trichosanthes cucumerina against experimentally induced liver injury.
OBJECTIVE: Punarnavashtak kwath (PNK) is a classical Ayurvedic formulation, mentioned in Ayurvedic literature Bhaishajya Ratnavali, for hepatic disorders and asthma. This study investigated the hepatoprotective activity of PNK to validate the traditional use of this formulation. MATERIALS AND METHODS: PNK was prepared in the laboratory according to the method given in Ayurvedic literature. Phytochemical screening was performed to determine the presence of phytoconstituents.
Justicia adhatoda (vasaka) leaves have long been used in Indian Ayurvedic system of medicine as antitussive. Its crude extract has been previously reported to have hepatoprotective activity. Vasicinone was isolated from leaves of J. adhatoda, column purified and characterized using, TLC UV, FT-IR and 1H NMR. The isolated vasicinone was evaluated for hepatoprotective activity using (CCl4)-induced acute hepatotoxicity model in mice. CCl4 treatments lead to significant increase in SGOT, SGPT, ALP levels.
Drug Metabolism and Disposition: The Biological Fate of Chemicals
Silymarin, a mixture of polyphenolic flavonoids extracted from milk thistle (Silybum marianum), is composed mainly of silychristin, silydianin, silybin A, silybin B (SB(B)), isosilybin A (ISB(A)), and isosilybin B. In this study, the plasma concentrations of free (unconjugated), conjugated (sulfated and glucuronidated), and total (free and conjugated) silymarin flavonolignans were measured using liquid chromatography-electrospray ionization-mass spectrometry, after a single oral dose of 600 mg of standardized milk thistle extracts to three healthy volunteers.
