Andrographis paniculata is an annual herbaceous plant in the family Acanthaceae, native to India and Sri Lanka. It is widely cultivated in Southern and Southeastern Asia, where it has been traditionally used to treat infections and some diseases. Mostly the leaves and roots were used for medicinal purposes.

Medicinal use
Since ancient times, A. paniculata is used in traditional Siddha and Ayurvedic[5] systems of medicine as well as in tribal medicine in India and some other countries for multiple clinical applications. The herb has a number of purported medicinal uses, although research has found evidence of its effectiveness is limited to treatment of upper respiratory infection, ulcerative colitis and rheumatic symptoms; in particular, there is no evidence of its effectiveness in cancer treatment.[6] According to the Mayo Clinic Book of Alternative Medicine from Wikipedia
