Phyllanthin is a natural compound with multiple biological activities, particularly for liver health. It is used in herbal medicine and traditional formulations as a key ingredient in supplements and remedies to support and restore liver function, reduce liver inflammation, and protect against damage from toxins or viruses, such as the hepatitis B virus. It helps in treating liver disorders like hepatitis and jaundice.

It exhibits antioxidant and anti-inflammatory properties, contributing to cellular protection and reducing oxidative stress in the body, which may aid in anti-aging and preventing certain chronic diseases, such as diabetes and heart disease.

Some research indicates potential anti-cancer effects, particularly against liver and breast cancer cells, though these are still in laboratory studies.

Overall, phyllanthin is primarily employed in herbal products for liver protection, detoxification, and immune health, with ongoing research for future pharmaceutical applications.
