 '''Bahuvadini''' or '''Cannabis sativa''' is an annual herbaceous plant in the Cannabis genus, a species of the Cannabaceae family. People have cultivated Cannabis sativa throughout recorded history as a source of industrial fibre, seed oil, food, recreation, religious and spiritual moods, and medicine. Each part of the plant is harvested differently, depending on the purpose of its use. 

Most varieties contain cannabinol and cannabinin; Egyptian variety contains cannabidine, cannabol and cannabinol, their biological activity being due to the alcohols and phenolic compounds. Resin contains crystalline compound cannin. Cannabis yields 421 chemicals of various classes—cannabinoids, cannabispirans and alkaloids. More than 60 cannabinoids have been isolated, the most important one is delta-9 tetrahydrocannabinol (THC).<ref name="chemical composition"/>

Propagation mainly by seed. Experimentally, drug plants have been propagated from cuttings but such plants do not come true as to drug content of parent. Seeds stored in cool, dry place remain viable for up to two years. Hemp seed sown as early in spring as possible. Before sowing, land is plowed (in fall) several times to a depth of about 20-23 cm and repeatedly harrowed the land. In spring the land is harrowed again and rolled, making a firm tilth over the entire surface. In some areas a first plowing is done in the fall and red clover or lupin planted; in January or February a second plowing turns these under as a green-manure<ref name="How to plant/cultivate"/>
