Evaluating the Impact of Ayurvedic Alimentary Protocols (Pathya-Apathya) on the Gut-Skin Axis in the Management of Kustha (Skin Disorders)

Introduction: Ayurveda emphasizes the prescription of Pathya and Apathya as an essential responsibility of the Vaidya for achieving Rogaharana and Swasthya rakshana. Pathya acts as a Prakriti-sthapana Upaya, maintaining physiological balance, while Apathya functions as a Nidana responsible for disease initiation and progression. Ayurvedic alimentary protocols may influence gut microbiota, digestion (Agni), and systemic metabolism, thereby contributing to improved skin health. Materials and Methods: This article is based on a literary review of Ayurvedic texts including Brihattrayi, Bhela Samhita, Vangasena, Basavarajiya, Yogaratnakar and relevant Nighantus. Results and Discussion: Ayurveda considers Pathya–Apathya a scientific dietary and lifestyle approach in disease management. Kustha Roga is Tridoshaja Vyadhi predominantly Pitta-Kapha Pradhana; hence, Pathya Ahara-Vihara focus on Pitta-Kapha Shamana using Laghu, Ruksha, Tikta, Kaṣhaya Rasa, Shita or Ushna Virya. Pathya Ahara Vihara plays an important role in checking pathology at minute level, whereas Apathya Ahara Vihara aggravates Doshas and worsens the condition. Avoidance of Apathya, especially Viruddhahara and Abhishyandi Ahara, possibly reduces systemic inflammatory responses associated with chronic skin disorders. Conclusion: Pathya–Apathya forms an integral therapeutic component in Kustha Roga, where appropriate diet and lifestyle alone can act as effective Chikitsa by pacifying Doshas and preventing Ama formation and recurrence.
