About Andrographis Paniculata

Andrographis paniculata, the Kalmegh of the Ayurveda, is an erect annual herb extremely bitter in taste in each and every part of the plant body. The plant is known in north-eastern India as 'Maha-tita', literally 'king of bitters', and known by various vernacular names . It is also known as 'Bhui-neem', since the plant, though much smaller in size has a similar appearance and has the same bitter taste as that of Neem (Azadirachta indica).

In Malaysia, it is known as 'Hempedu Bumi' literally means 'bile of earth' since it is one of the most bitter plants that are used in traditional medicine. In Tamil it is called 'Sirunangai' or 'Siriyanangai'. The genus Andrographis consists of 28 species of small annual shrubs essentially distributed in tropical Asia. Only a few species are medicinal, of which Andrographis Paniculata is the most popular.

The plant is well known in Bengal by the name 'Kalmegh'. It is a principal herb in the domestic medicine called 'Alui', which is given to infants. Both in Ayurveda and Unani, it is confused with 'Chitetta' (Swertia chirata), but both are different plants. It is widely available in Arabia. It is mentioned in the official pharmacopoeia of India.. It is given for fever along with several herbs. It was advertised in England as a substitute for quinine.

It is widely cultivated in southern Asia, where it is used to treat infections and some diseases, often being used before antibiotics were created.

Andrographolide, the major constituent of the extract, is implicated in its pharmacological activity. A study has been conducted on the cellular processes and targets modulated by andrographolide treatment in human cancer and immune cells.

Results suggest that andrographolide is an interesting pharmacophore with anticancer and immunomodulatory activities and hence has the potential for being developed as a cancer therapeutic agent. The Tamils have been using Nilavempu - as it is called in Tamil for centuries. In Siddha medicine, Andrographis Paniculata is used widely to treat fevers like chikenguinea, swine-flu, typhoid etc.
