COMPREHENSIVE LITERATURE REVIEW ON PUREESHA PAREEKSHA (AYURVEDA STOOL EXAMINATION)

Pureesha Pareeksha, the Ayurvedic examination of stool, is an important traditional method used to understand a person’s digestive health and overall internal balance. In Ayurveda, stool analysis helps assess the strength of Agni (digestive fire), the balance of the Doshas—Vata, Pitta, and Kapha—and the presence of Ama (undigested toxins). As part of classical diagnostic methods such as Ashtasthana Pariksha, physicians observe different characteristics of stool, including its color, consistency, odor, quantity, and other physical features. Ancient Ayurvedic texts like Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya describe how these features can indicate digestive disorders and various disease conditions. A unique technique called Jala Nimajjana Pariksha, in which stool is placed in water to see whether it floats or sinks, is used to understand digestive efficiency and the presence of toxins. Traditionally, this method helped diagnose conditions such as constipation, diarrhea, parasitic infections, and Dosha imbalances. Although modern stool examinations rely on laboratory tests to detect infections, blood, or chemical changes, Pureesha Pareeksha provides a broader and more holistic understanding of digestive health. Despite some limitations like subjectivity and the need for better scientific validation, current research is exploring ways to standardize and integrate this traditional method with modern diagnostic approaches for a more comprehensive evaluation of gastrointestinal health.
