Out of the five major types of psoriasis explained in the modern science (Plaque, Guttate, Erythrodermic, Pustular and Inverse psoriasis), Plaque psoriasis is the most commonly (90%)affected type of psoriasis. It typically presents as red patches with white scales on top. Areas of the body most commonly affected are the back of the forearms, shins, navel area, and scalp.
According to Ayurveda, this disease is known as Kitibha, which results from vitiation of the Vata and Kapha dosha. In Ayurveda, we call these symptoms as Syavam(blackish discolouration), Kinakharasparsa(dry to touch), and Parusa(roughness over patches), respectively. Various sites of the body such as scalp, face, trunk, limbs, palms, and soles involve in psoriasis. The chronic nature, recurring pattern, and visibility of psoriasis produce a great adverse impact on the psychological and social aspects of patients’ life.
