Phyllanthus are low shrubs common across southern Asia and Australia. In parts of India the herb is renowned for its success in treating hepatitis and jaundice. Direct antiviral effects have been demonstrated in human and animal HVB studies, which could be measured by a reduction in the virus surface antigen. Several Australian species have also shown antiviral properties in animal studies on HVB but no clinical data is available. In India fresh roots are considered the most effective for jaundice.
Australian use is restricted to prescription by medical herbalists.
