Nature’s Signature in Ayurveda with an Ethnopharmacological Approach: A Narrative Review

Abstract

Abstract: The nature's signature in Āyurveda i.e. Doctrine of Signatures (DOS), which calls for utilizing natural substances that resemble a particular body part or organ, is consistent with the ethnopharmacological practice of choosing therapeutic plants based on their visible physical qualities. In order to promote health and treat ailments, the ancient Indian medical system known as Āyurveda employs natural ingredients including plants, minerals, and animal products. The study of conventional medicine and the application of natural products for therapeutic reasons are known as ethno-pharmacology. This review explores various research on ayurvedic herbs, their doctrinal signature, and the status of our understanding of ethno-pharmacology. However, by integrating Āyurveda plants' doctrinal signatures with ethnopharmacological methods, it might be better to comprehend the therapeutic potential of plants and create novel treatments for a range of ailments. Combining these two perspectives might assist in understanding how nature may heal and how natural medicines could improve health and wellness. It was believed that a plant containing parts that resembled portions of human bodies, animals, or other items had practical use for those parts, animals, or objects. This philosophy was shown in some of the Indian medicinal plants that are discussed in this article.
