Langhana is an important therapeutic principle in Ayurveda that aims to reduce bodily heaviness, eliminate metabolic toxins(Ama), and restore the balance of Dosha by enhancing digestive fire (Agni). It is indicated in conditions associated with impaired digestive, obstruction of body channels (Srotorodha), accumulation of Ama, and metabolic disorders. Aacharya Charak and Aacharya Vagbhatt, describe various types of Langhana including fasting (Upavasa), light diet (Pachana), physical exercise (Vyayama), exposure to sun and wind (Atapa and Maruta), thirst therapy (Pipasa), which are selected according to the patient’s strength (Bala), disease severity (Roga Bala). Langhana promotes detoxification, improves digestion and metabolism, reduces excess Kapha and Meda, and enhances lightness and clarity in the body. Emerging scientific evidence also suggests beneficial effects of fasting on metabolic health and mental well-being. Thus, Langhana represents a cost-effective, preventive, and therapeutic approach with significant relevance in lifestyle and metabolic disorders.
