According to Ayurveda, Psoriasis appears due to imbalance of Vata and Kapha. Manifest in the skin and cause accumulation of toxins. These toxins accumulate in deep tissues like rasa (nutrient plasma), rakta (blood), mansa (muscles), and lasika (lymphatic). These toxins cause contamination of deeper tissues, leading to Psoriasis. Purification of blood and tissues is the primary aim of Ayurvedic treatment in cases of Psoriasis. Toxins are cleansed from the body and the digestion restored to prevent further accumulation. Nourishing herbs are then administered to strengthen and tone the tissues to promote complete healing of the skin.
