edit]Etymology
Andrographis paniculata 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 (see the table below). As an Ayurveda herb it is known as Kalmegh or Kalamegha, meaning `dark cloud.' It is also known as ‘Bhui-neem’, ‘neem of the ground,’ since the plant, though being a small annual herb, has a similar strong bitter taste as that of the large Neem tree (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. The genus Andrographis consists of 28 species of small annual shrubs essentially distributed in tropical Asia. Only a few species are medicinal, of which A. paniculata is the most popular.
