Phyllanthus niruri L., (Syn. P. fraternus Webster), Euphorbiaceae, is a common kharif (rainy season) weed found in both cultivated fields and wastelands. In different Indian languages it is known as bhuiaonla (Hindi) kiranelligida (Canarese), bhuiavli (Marathi), ajata, amala, bbumyamalaki, sukshmadala, vituntika (Sanskrit). Although considered a problematic wee for farmers it is a valuable medicinal for herbalists (Oudhia and Tripathi 2002) and holds a reputed position in both Ayurvedic and Unani systems of medicine. Recently it has attracted the attention of researchers, because of its hepatoprotective properties.

In different parts of India, specially, in Chhattisgarh state, there is a rich traditional medicinal tradition concerning this weed (Caius 1986; Oudhia and Tiwari 2001). In many parts of India, it is commonly used for the treatment of snake bite. The active compounds phyllanthin and hypophyllanthin have been isolated from leaves. Recently, lignansniranthin, nirtetralin, and phyltetralin have been isolated from leaves. (Rastogi and Mehrotra, 1991) It is a major component of many popular liver tonics in India including Liv.-52. Fresh juice and powder of dried plant are used most frequently in Ayurvedic preparations (Sastry and Kavatherkar, 1991). The plant is used as a fish poison. In many parts of India specially in deserts, the roots mixed with Commiphora mukul are given to camels to cure indigestion. The decoction of leaves and stem are used for dyeing cotton black.
