Historical or traditional use (may or may not be supported by scientific studies)
Phyllanthus has been used in Ayurvedic medicine for over 2,000 years and has a wide number of traditional uses including internal use for jaundice, gonorrhea, frequent menstruation, and diabetes and topical use as a poultice for skin ulcers, sores, swelling, and itchiness. The young shoots of the plant are administered in the form of an infusion for the treatment of chronic dysentery.2
Active constituents
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.3 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.4 Clinical trials with hepatitis B patients have used 900-2,700 mg of phyllanthus per day.
How much is usually taken?
Research has used the powdered form of phyllanthus ranging from 900-2,700 mg per day for three months.5
Are there any side effects or interactions?
No side effects have been reported using phyllanthus as recommended in the amounts above.
At the time of writing, there were no well-known drug interactions with phyllanthus.
