Vetasa

(Willow)
Sanskrit: वेतस • Botanical: Salix caprea Linn.

Vetasa (Salix caprea) is a tree found near water bodies and rivers. It grows commonly along riverbanks. The name Vetasa is used for several species of willow. Three species are mentioned: Salix caprea (Sallow), S. tetrasperma (Indian Willow), and S. acmophylla. The bark is the main part used medicinally and contains Salicin (4-10%), the precursor to aspirin. Vetasa is cold in potency and useful in Pitta disorders, bleeding conditions, and fevers. The bark is astringent and antipyretic. It is mentioned as growing near water - 'Nadija' meaning river-born is one of its names. The text confirms Bhavamishra's description that Vetasa bark when used in decoction acts as a febrifuge. Calamus tenuis (a reed/cane) is also sometimes called Vetasa but is a different plant. Dose: bark decoction 1-2 tola; bark powder 5-10 ratti.
