Psoriasis--pathophysiology, conventional, and alternative approaches to treatment.

Psoriasis is a common T-cell-mediated immune disorder characterized by circumscribed, red, thickened plaques with an overlying silver-white scale. It occurs worldwide, although the incidence is lower in warmer, sunnier climates. The primary cause of psoriasis is unknown. During an active disease state, an underlying inflammatory mechanism is frequently involved. Many conventional treatments focus on suppressing symptoms associated with psoriasis and have significant side effects. This article reviews several of the researched natural approaches to psoriasis treatment, while addressing its underlying cause.
