Med. Prop. and Action. From its physical characters and physiological effects, it appears to rank amongst the nervine stimulants, approximating probably more nearly to Valerian than to any other drug. It is used by the Russian physicians in Low Typhoid Fevers and in cases of Asthenic Dysentery and Diarrhoea. It has also been employed by them with alleged success in Cholera. Dr. Thielmann, of St. Petersburg, informed Drs. Wood and Bache that he depended mainly on this remedy in Delirium Tremens, having found it superior to Opium in its composing influence over that complaint.* Dr. Granville recommends it in Gastric Spasm, Hysteria, Chlorosis, Amenorrha, Dysmenorrha. Paralysis of the Extremities, Epilepsy, and other Nervous Disorders: but its efficacy in these cases is far from being established. Dr. Murawieff, a Russian physician, has employed a resinous extract from this root, which he regards as its active principle, in doses of gr. j. - ij. three or four times a day, and affirms its utility in Chronic Bronchitis. Chronic Pneumonia, Moist Asthma of old, anmic. and scorbutic patients, in Atonic Dysentery, Leucorrha, Hypochondriasis, and Hysteria.
