Nerves Sarpagandha’s sedative properties are legendary. It nourishes majja dhatu and reduces vatato benefit insomnia and agitation. It is also used in manic psychological disturbance as a sedating tranquilliser. It is a wonderful brain tonic going directly to manovahasrotas (Gogte 2000).
Heart Its affinity for the blood takes it directly to the heart. It swiftly dilates the blood vessels, causing high blood pressure to drop and the heart rate to reduce. Use drop-by-drop doses until the blood pressure has reduced. If the dose is wrong it can cause hypotension and lead to giddiness and sleepiness. It is a symptomatic remedy that treats the high blood pressure via the nervous system and so benefits high blood pressure caused by high vata and arteriosclerosis. It should be used with a diuretic to prevent fluid retention and to support its antihypertensive effect (WHO 1999, Tillotson 2001).
Pain Its analgesic properties are useful in dysmenorrhoea with a spasmodic uterus and also in colic from intestinal inflammation and spasm (Gogte 2000).
