The leaves and flowers of Cannabis are narcotic and astringent. They are chewed and smoked. The seeds, mixed with opium, areca, and sugar, produce a kind of intoxication, and are used for this purpose by the people of India. An alcoholic extract of the plant, Churrus-Extractum Cannabis (Ph. U. S.)-has been used in India, and since then in Europe and in this country, as a narcotic and anti-convulsive, in the dose of from half a grain to ten or more. It requires, however, great caution in its administration. The pure resin- Cannabine, Haschischine- is active in the dose of two-thirds of a grain. The dried plant, which has flowered, and from which the resin has not been removed, called Gunjah, Ganjah, Guaza, and Guazah, Haschisch, Haschich, Hachisch, Hashish, or Chaschisch; of the Arabs, consists of the tops and tender parts only of the plant, collected immediately after inflorescence, and simply dried.
