Phyllanthus

Parts Used & Where Grown

Phyllanthus is an herb found in central and southern India. It can grow from 30–60 centimeters in height and blooms with many yellow flowers. Phyllanthus species are also found in other countries, including China (e.g., Phyllanthus urinaria), the Philippines, Cuba, Nigeria, and Guam.1All parts of the plant are used medicinally.

How It Works

Phyllanthus primarily contains lignans (e.g., phyllanthine and hypophyllanthine), alkaloids, and flavonoids (e.g., quercetin).

Phyllanthus blocks DNA polymerase, the enzyme needed for the hepatitis B virus to reproduce. In one study, 59% of those infected with chronic viral hepatitis B lost one of the major blood markers of HBV infection (e.g., hepatitis B surface antigen) after using 900 mg of phyllanthus per day for 30 days.2 While clinical trials on the effectiveness of phyllanthus for HBV have been mixed, the species P. urinaria and P. niruri seem to work better than P. amarus.3 Clinical trials with hepatitis B patients have used 900–2,700 mg of phyllanthus per day.
