Ativisa

Ativisa (Aconitum beterophyllum)

Ativisa is mentioned in ancient scriptures of Ayurveda and has been used since centuries. Aconite is one of the oldest known drugs identified by Susruta. Poisonous aconite is called as Vatsa nabha – Aconitum ferox, which is one of the thirteen poisonous bulbs. In Ayurvedic pharmacy, aconite is used after mitigation by boiling the roots in cow’s urine. It is believed that by this process not only detoxification is achieved, but the visa (poison) present in the roots changes to nectar Ativisa has numerous synonyms delineating its peculiarities viz. Mahausadhi – a divine drug, sisu bhaisjya – medicament for paediatric diseases, bhangura – fragile , kasmira – gruws in Kashmir etc. Maharsi Caraka has categorized the plant as lekhaniya – a reducing herb and arsoghna – anti – haemorrhoidal.. Susruta has cited it as stanya sodhana – lactodepurant. The other few properties like atisaraghna – antidiarrhoeal, amapacaka – digests ama or toxins and visaghna – anti – toxin, of ativisa have been mentioned in various tests of Ayurveda.

The flowers are blue or violet coloured, in slender raceme. The fruit of 5 follicles, pericarp papery, slightly veined, minutely downy. The seeds are large, irregularly angled, bright brown, smooth or somewhat wrinkled. The roots are tuberous, biennial, paired and are very friable (hence called, bhangura) and taste very bitter. The roots vary in colour white, yellow, red and black out of which, the white variant is the best.
