Psoriasis Information


Plaque psoriasis is a chronic inflammatory disease with an unknown cause and no cure. Much research is based on the theory that psoriasis is a T cell mediated disorder. This review suggests that the pathogenesis of psoriasis fits the general picture of a type IV hypersensitivity reaction. Orthodox and herbal approaches to treatment are both shown to be more beneficial if they are tailored to the individual and address psychosocial issues.

Psoriasis is a chronic, inflammatory, non-contagious, skin disease affecting over 2% of the population world-wide. Many different forms of psoriasis exist including: guttate, flexural, scalp, erythrodermic, pustular, palmar/pedal, and psoriatic arthropathy. This review focuses on the most common form - chronic plaque psoriasis.
