Psoriasis is a chronic skin condition which often runs in families and is characterised by itchy, scaly pink patches commonly appearing on the elbows, knees, shins and scalp, while the fingernails and toenails may also be affected. It is difficult to know what causes psoriasis, but a combination of a healthy diet and appropriate skin ointments enables most sufferers to keep their symptoms under control. 

The reason that ointments are preferred is that it keeps the actives against the skin for longer. Ointments also help to prevent moisture loss.

There is some evidence to support the theory that impaired ability to neutralise and excrete dietary toxins via the liver may contribute to the condition. Traditionally, naturopathic therapies have emphasised liver health in dealing with psoriasis; for this reason it is also recommended that sufferers avoid alcohol.
