Abstract

Neeli or Indian indigo is an Ayurvedic herb used in the management of visha (poison) and its related conditions. Many references regarding the visha hara (anti-toxic) property of the drug is available in the classics. It forms the ingredient of various Agada yogas (formulations for the treatment of poison and toxic conditions) and other commonly practiced formulations. In addition to the brihat trayis (three main treatise in Ayurveda classics), the drug is frequently mentioned in Keraleeya visha chikitsa granthas (Classic books followed in Kerala for the treatment of poisonous conditions) like Prayogasammucchayam, Kriyakaoumudi, Kodasherymargam etc which highlights its potency and the important role played by Neeli even in the management of high potent poisons like mandali visha (viper bite). Proper evaluation of the drug and its properties with genuine research studies may help practitioners of Agadatantra to tackle the innumerable ailments arising due to exposure to various toxins, seen in the present era, with a better and cost effective treatment. In this article, an attempt is made to throw light on the significance of the anti toxic property of the drug Neeli and its potency in treating various poisonous conditions including snake bites.
