Kalmegh (Andrographis paniculata Nees.) is an important medicinal plant which is employed in the Indian traditional system of medicine (Folk medicine), Homeopathy, Ayurveda and Unani system of medicine. Its leaves, stem and infl orescence are used as medicine. Its major bitter principles are diterpenoids - andrographolide and neo-andrographolide. It is useful in the treatment of liver disorders, hepatitis, dysentery, febrifuge etc. Th e herb kalmegh is also used as a liver tonic, in hyperdispsia, wounds, ulcers, chronic fever, malarial and intermittent fevers, infl ammations, coughs, bronchitis, skin diseases, leprosy, colic, fl atulence, diarrhoea, dysentery, haemorrhoids. Th is study of germination revealed that germination was essentially complete aft er 16 d. KNO3 and GA3 improved the seed germination percentage. Germination in the presence of NaHClO3 was rapid, taking only 8 d. Being a medicinal plant, KNO3 and NaHClO3 treatments are economic and easily applied by nursery workers and poor farmers in developing mass planting stocks.
