A conceptual study on Trividha Atisevaniya Varjya Dravya w.s.r. to Kshara (Alkali)
Kshara has been used as medicine as well as food since ancient times. In Charaka Samhita it has been mentioned that three medicinal substances viz. Pippali, Kshara (alkali) and Lavana (salt) can be used as emergency medicine, but they should not be consumed in excess (Ati Upayunjita). If they are consumed in excess quantity they will cause several adverse effects in the body. There is no specific explanation available for the term Ati Upayunjita. However excess use also can be taken in two ways i.e. in high dose and/ or for continuous use for long duration. For the drug Kshara, the word Ati Upayunjita is mentioned for continuous use for longer duration. What time period considered being a long time to use has not been clarified by the Acaryas. So this present review article highlights the conceptual aspects of Trividha Atisevaniya Varjya Dravya w.s.r. to Kshara.
