About

Justicia adhatoda commonly known in English as Malabar nut, adulsa, adhatoda, vasa, vasaka, is native to Asia. Adathoda means 'untouched by goats' in Tamil. The name derives from the fact that animals like goats do not eat this plant due to its extreme bitter taste.

The plant's native range is Afghanistan, the Indian subcontinent (Bangladesh, India, Pakistan, Nepal and Sri Lanka), Laos, Myanmar and Vietnam. It has been introduced elsewhere.
