Origin, Distribution and Composition
Indian Hemp is a robust, tall, erect, annual herb, 1 to 5 metres high, usually with male and female plants in roughly equal numbers. It has angular stems bearing palmately or hand shaped divided leaves with greenish flowers. The hemp plant provides three products, namely, fibre from the stems, oil from the seeds and narcotic from the leaves and flowers.
The hemp plant was originally a native of Western and Central Asia. It has been cultivated since ancient times in Asia and Europe. The plant is said to have reached China more than 4,500 years ago. It spread to the New World in post-Columbian times.
In India cultivation of this plant is controlled and permitted only in the districts of Almora, Garhwal and Nainital (excluding the Terai and Bhabar) in U.P. To a small extent it is also cultivated in Kashmir, Travancore and Nepal.
The chief constituents of Indian hemp are cannabinol, pseudocannabinol and cannabinin. It also contains cannin, a resin. The biological activity of cannabis is due to alcoholic and phenolic compounds. The resin contains a crystalline compound, cannin.

Healing Power and Curative Properties
Preparations of Indian hemp have been in use as intoxicants in Asiatic countries and Africa from time immemorial. Bhang, ganja and charas have been habitually used in these parts of the world. Its narcotic and anodyne properties were appreciated by Western
medical men in the early years of the last century and as incorpared
in the British and United States Pharmacopoeias.
The leaves of the plant are used as a drug to reduce excitement, irritation and pain as well as to induce deep
sleep. They are also used as a drug to counteract spasmodic disorders, to increase the secretion or bleeding. As sedative and anodyne, they are given in doses of 2.5 grams.
Three types of narcotics are produced from the hemp plant, namely bhang or hashish which constitute the dried leaves and flowering shoots of male and female plants— has a low resin content. Ganja which is the dried unfertilized female inflorescences of special varieties grown in India and charas, which is the crude resin collected by rubbing the tops of the plant with the hands or beating them with a cloth. In all these drugs, the active principle is a resin from the
glandular hairs on its leaves, stems and inflorescences.
