Phyllanthus has a long tradition of use in the Hindu Ayurvedic system of medicine and it has long been used as a medicinal agent in cultures around the world. It is usually found in central and southern India, where it can grow from one to two feet in height and have blooms with many yellow flowers. Phyllanthus can also be found in many other countries including the Philippines, Cuba, Nigeria and Guam.

Traditionally, phyllanthus has been used to treat jaundice, gonorrhea, frequent menstruation, dysentery and diabetes. It has also been used topically as a treatment for skin ulcers, sores, swelling, and itchiness. Modern research with phyllanthus focuses on its potential for fighting viruses, specifically the hepatitis B virus. Presented at the 3rd International Congress on Phytomedicine in Munich, a laboratory study reported that phyllanthus seems to have the ability to inhibit two of the pro-inflammatory enzymes (COX-2 and iNOS), making it potentially useful in the fight against inflammatory diseases such as arthritis.

One important note: There is another species of phyllanthus, Phyllanthus emblica, that is also commonly used in the Ayurvedic system of medicine and should not be confused with the varieties we’re discussing here.

Reported Uses

Current research has focused on phyllanthus’ potential for the treatment of hepatitis B. Indeed, studies suggest that it may suppress the growth and replication of the virus. (2) , (3) , (4) It is important to note that scientists believe that two particular varieties of phyllanthus, Phyllanthus niruri and Phyllanthus urinaria, may be more effective in the treatment of hepatitis B than Phyllanthus amarus. What’s more, while phyllanthus may help decrease the amount of hepatitis B virus found in the blood stream, it has not been reported to remove all of the virus and should not be considered a cure. Medical assistance should always be sought in hepatitis infections.

In addition to helping the body fight hepatitis B, phyllanthus may also support the overall health of the liver. Other studies have looked at the potential use of phyllanthus in protecting against liver injuries, as well as cancerous tumors of the liver. (5) , (6)

Finally, some research suggests that phyllanthus may help fight the malaria parasite. (7)
