A Literature Review on Manikkadai Nool a Traditional Diagnostic Tool in Siddha Medicine

Abstract

Manikkadai Nool (wrist circumference diagnostic technique) is one of the ancient, noninvasive diagnostic methods described in Siddha medicine¹, ². It involves measuring the wrist circumference using finger units (viralkai alavu) to assess physiological and pathological conditions of an individual. ¹ This literature review aims to consolidate traditional references and clinical relevance of Manikkadai Nool in diagnosing Vatha, Pitham, and Kabha derangements and predicting prognosis ¹, ². The study compiles data from classical Siddha texts and traditional to interpret the correlation between wrist measurements and various disease states. Findings reveal that Manikkadai Nool serves as a valuable diagnostic and prognostic indicator reflecting the status of Uyir Thathukkal (vital humors) ². It emphasizes the holistic approach of Siddha medicine in assessing health without invasive procedures.
