Phyllanthus Urinaria (Euphorbiaceae)

Latin: Phyllanthus Urinaria (common names: Phyllanthus Amarus, Phyllanthus Niruri)

Pinyin:  Zhen Zhu Cao



Physical Characteristics*

Phyllanthus is an herb that grows in remote Asian tropical, sea breeze type climates especially in the Indonesian islands as well as central and southern India.  It can grow to 30-60 cm in height and blooms with many yellow flowers. All parts of the plant are employed therapeutically. Phyllanthus species are also found in other countries, including China (e.g., Phyllanthus urinaria), the Philippines, Cuba, Nigeria, and Guam.[1]

Other similar species are Phyllanthus amarus and Phyllanthus niruri. The difference between Phyllanthus urinaria and p. amarus or p. niruri is that the urinaria has larger leaves than the latter and the fruit of p. urinaria is wart-like.

Traditional Chinese Medicinal (TCM) Uses*

Phyllanthus has been used for generations in China to promote healthy elimination of gallstones and kidney stones, as an immune system stimulator and for those with liver disease.  In TCM, practitioners use this herb, with its “cool” nature, to clear dampness, heat and toxicity. Phyllanthus urinaria primarily contains lignans (e.g. phyllanthine and hypophyllanthine), gallic acid, alkaloids, and bioflavonoids (e.g. quercetin). While it remains unknown as to which of these substances has an antiviral effect, researchers believe that this herb acts primarily on the liver.*

Research in China has shown that Phyllanthus has been shown to block DNA polymerase, which is the enzyme needed for the hepatitis B virus to reproduce. In one 30 day 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 phyllanthus.[2]  While clinical studies on the outcome of phyllanthus and HBV have been mixed, the species P. urinaria and P. niruri seem to work better than P. amarus.[3]*

Other research has revealed other possible benefits like helping to soothe the liver, detoxification of the liver and kidneys, relief from pain and inflammation, reducing oxidative stress, and an ability to inhibit hepatitis B virus DNA replication. [4,5]*

It is believed that the possible benefit that phyllanthus urinaria provides in cases of liver damage could be due to the plants anti-viral activity.*

Additional Info: in Ayurvedic medicine, Phyllanthus has been used for over 2000 years in India for many medicinal uses for those with liver disease including hepatitis.*
