A Review on Synergy of Visha-Upavisha through its ADME Profiling and Pharmacological Validation

Abstract

Ayurveda, with its profound pharmaco-toxicological wisdom, describes Visha and Upavisha as potent substances that, despite their inherent toxicity, possess significant therapeutic potential when subjected to proper purification and formulation protocols. In recent years, the integration of traditional knowledge with modern biomedical science has enabled a renewed evaluation of these agents through ADME (Absorption, Distribution, Metabolism, and Excretion) profiling and pharmacological validation. This review highlights the emerging scientific understanding of these substances, focusing on their synergistic roles when combined with other herbs or minerals. It underscores the critical importance of detoxification processes in reducing toxicity and enhancing pharmacological efficacy, particularly by influencing the ADME characteristics of these compounds. Recent pharmacological studies employing advanced analytical techniques such as LC-MS/MS, molecular docking, and in vitro cytotoxicity assays validate their roles in diverse therapeutic domains, including immunomodulation, anticancer activity, antimicrobial effects, and inflammatory disorders. This work primarily aims to elucidate how inherently toxic drugs (Visadravyas, Rasaoushadhis), after undergoing accurate purification can act along with Herbal drugs (Kasthoushadhi) specifically on targeted sites to deliver desired therapeutic outcomes through their active constituents. Moreover, it emphasizes the judicious use of these drugs, advocating for strict adherence to traditional detoxification and dosing protocols to maximize benefits while minimizing risks, thereby ensuring their safe and effective incorporation into contemporary integrative medicine.
