Hyoscyamus niger - Pārasīkayavānī, Henbane
Pārasīkayavānī consists of the seed of Hyoscyamus niger. It is an annual or biennial herb. It is native to the Mediterranean region and temperate Asia, occurring in Western Himalayas from Kashmir to Kumaon at an altitude of 1600 to 4000 m, imported into India.
The chief constituent of Henbane leaves is the alkaloid Hyoscyamine, together with smaller quantities of Atropine and Hyoscine, also known as Scopolamine. The proportion of alkaloid in the British Pharmacopoeia dried drug varies from 0.045 to 0.14 per cent.
