AN AYURVEDIC REVIEW ON TWACHA

Twacha (skin) is described in Ayurveda as an important organ of both structural and functional significance, serving as the seat of Sparshanendriya (sense of touch) and reflecting the overall health status of an individual. Classical Ayurvedic texts such as Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya provide a detailed description of Twacha, including its origin, layers, functions, and pathological involvement in various diseases. Twacha is said to be formed from the essence of Rakta Dhatu during embryological development and is closely associated with Doshas, Dhatus, and Agni. Different Acharyas have described varying numbers of layers of Twacha, each having specific thickness, characteristics, and disease associations. Moreover, Twacha plays a vital role in thermoregulation, protection, sensation, and cosmetic appearance. This review article aims to critically analyze the Ayurvedic concept of Twacha and correlate it with modern anatomical and physiological understanding of the skin. By exploring classical references and contemporary scientific literature, this review highlights the relevance of Ayurvedic concepts in understanding skin health, disease manifestation, and holistic management. The integrative approach presented may help bridge the gap between traditional Ayurvedic knowledge and modern dermatology, opening avenues for research and clinical application.
