Traditional Suthi Muraigal (Purification) of Metals A Review

Siddha medicine is one of the oldest traditional healing systems that utilise metals to transform hazardous components into potent therapeutic agents. The traditional Indian medicine “Siddha†uses metals that are toxic or have no proven toxicity. According to traditional purification methods in Siddha medicine, the toxic effects of heavy metals such as iron, copper, lead, zinc, steel, etc., are reduced [2]. These metals may act on specific diseases without purification, but at high doses they can cause severe complications. The purification techniques, collectively called “Suthi†(purification), involve a multi-step process that varies according to the metal, including washing and boiling, and are aimed at reducing toxicity and enhancing medicinal properties.[1] Scientific analysis indicates that purification yields safer components suitable for clinical applications. Metals are used after impurities and toxic components are removed. Non-purified metals can cause multi-organ failure and systemic effects. To ensure and prevent side effects, purified metals are essential for medicines [2]
