Himalaya Serpina Tablet is an Ayurvedic formulation for the management of mild to moderate hypertension. Serpina decreases the adrenergic tone and controls anxiety. It is therefore beneficial in the treatment of anxiety disorders as well.

Rauwolfia (Sarpagandha) is a pungent smelling herb, which is a potent anti-hypertensive. Its Sanskrit name, Sarpagandha, literally translates to 'smells like a serpent'. Reserpine, an active compound found in Rauwolfia, renders the herb its antihypertensive property. Its anti-hypertensive activity is attributed to a decrease in peripheral resistance and the resulting decrease in cardiac output.
