Abstract

Bhallataka (Semecarpus anacardium Linn.; Ancardiaceae) is mentioned under Upavisha group in Ayurvedic classics and it is described as a poisonous medicinal plant in Drugs and Cosmetics Act (India), 1940. Fruit of Bhallataka is used either as a single drug or as an ingredient in many compound formulations of Indian systems of medicine to cure many diseases. Tarry oil present in the pericarp of the fruit causes blisters on contact. The major constituent of the tarry oil is anacardic acid and bhilawanol, a mixture of 3-n-pentadec(en)yl catechols. Bhilawanol A and B are known as Urushiols, and also, anacardic acid is closely related to Urushiol. Urushiol-induced contact dermatitis is the medical name given to allergic rashes produced by the oil Urushiol. This paper deals with five case reports of contact dermatitis caused during different stages of Shodhana (purificatory measures) of Bhallataka fruit due to improper handling of the utensils and disposal of media used in Shodhana procedure and their Ayurvedic management. To combat these clinical conditions, the affected persons were advised external application with pounded Nimba (Azadirachta indica A. Juss.) leaves on the affected parts and internal administration of Sarivadyasava 30 ml thrice daily after food and Triphala Churna 5 g before food twice daily. Reduction of itching and burning sensation was observed after topical application.
