Abstract
Herbs have been one of the important and unique sources of medicines from the dawn of human civilization. Psoriasis is a common skin condition where the skin develops areas that become thick covered with silvery scales. It is a common problem, and millions of people in the world have psoriasis. Pathophysiology of the disease includes mainly the activation and migration of T cells to the dermis triggering the release of cytokines (tumor necrosis factor-alpha TNF-alpha, in particular) which lead to the inflammation and the rapid production of skin cells. The possible factors and triggers causing psoriasis include emotional stress, skin injury, systemic infections, certain medications and intestinal upsets. The herb which are used in the psoriasise disease are Aloe Vera (\Aloe barbadensis), Olive Oil (Olea curopaea), Turmeric (Curcuma longa), Coleus (Coleus Forskohlii), Cayenne (Capsicum annuum) etc. Conclusion: These plants are being used for curing many diseases as such in raw condition rather the being prepared as formulation; Standardization is an essential parameter to be done. It is a vital step in formulation since it determines the quality of the product and is essential to develop a protocol on standardization of every product available in the market to avoid variation arising between batch to batch.
