Description

The seeds of Celastrus paniculatus, the black oil plant or staff vine, represent a distinct Ayurvedic drug with a well-documented classical history. The woody climbing vine is native to the tropical and subtropical forests of the Indian subcontinent, Sri Lanka, and Southeast Asia, occurring in forest margins, riverine vegetation, and open woodland from the Himalayan foothills to peninsular India. Known in Ayurveda as Jyotishmati — ‘the luminous one’ — the seeds are documented in the Charaka Samhita and Sushruta Samhita as a primary Medhya (cognitive) Rasayana, traditionally incorporated into formulations for memory enhancement, intelligence, and nervous system tonic action. The fixed and essential oil from the seeds contains sesquiterpene alkaloids including celastrine and paniculatine. This entry covers the seeds specifically, as distinguished from the whole plant form.
