What is use of Rauwolfia ?

  • A.Analgesic
  • B.Antihypertensive
  • C.Expectorant
  • D.Laxative

Answer: B

Rauwolfia is used as an antihypertensive.

The root of Rauwolfia serpentina (sarpagandha) contains the alkaloid reserpine. Reserpine depletes noradrenaline from sympathetic nerve endings, which lowers blood pressure, and it was once also used as a tranquilliser.

It is not an analgesic, an expectorant or a laxative. Those uses belong to other drugs: opium alkaloids for pain, ipecacuanha or ammonium chloride for expectoration, and senna for constipation.
