ROLE OF RASA DHATU AND RASAYANA THERAPY IN MAINTAINING SKIN HEALTH: AN AYURVEDIC REVIEW

Ayurveda conceptualizes skin health (Twak) as a direct manifestation of internal physiological balance rather than an isolated cosmetic entity. Among the seven fundamental bodily tissues (SaptaDhatus), Rasa Dhatu occupies a primary position as the initial nourishing essence formed after digestion, responsible for sustaining cellular vitality and tissue integrity throughout the body.[1] Classical Ayurvedic texts emphasize that the qualitative and quantitative status of Rasa Dhatu profoundly influences skin hydration, complexion, texture, radiance, and resistance to aging.[2] The present review critically examines the Ayurvedic understanding of Rasa Dhatu in relation to skin health, highlighting the concept of TwakSaarata as an indicator of optimal tissue nourishment. It further explores the mechanisms through which Rasa Dhatu contributes to skin rejuvenation, immune competence, and anti-aging effects. Contemporary scientific evidence supporting the dermatological and rejuvenative potential of Ayurvedic herbs and Rasayana therapy is also analyzed. Medicinal plants such as Manjistha, Neem, Turmeric, Aloe vera, Sariva, Guduchi, Shatavari, Guggul, Lodhra, and Chandana exhibit antioxidant, anti-inflammatory, antimicrobial, and tissue-nourishing properties that validate traditional claims. Ayurveda thus provides a holistic and systemic approach to dermatology by addressing digestion, tissue metabolism, immunity, and rejuvenation at the cellular level. Although existing pharmacological and clinical studies are promising, further well-designed human trials are required to strengthen the integration of Ayurvedic interventions into contemporary dermatological practice.
