Olive oil has developed a reputation for being an effective treatment for mild cases of plaque psoriasis. It can be massaged directly onto affected areas of the skin (including the scalp) to relieve dryness and irritation as well as to facilitate healing.

Ways to administer olive oil that I have heard include rubbing light amounts of it on the skin (elbows and knees for example), adding it to regular bathwater and/or leaving it on the scalp overnight (in which case a shower cap would be needed to keep it from running all over one’s pillow).

Interesting: Ancient Egyptians used olive oil as a skin treatment over 4,000 years ago.

Generally, keeping one’s skin clean and moist is a great way to encourage the body’s natural resistance to psoriasis. Olive oil is both clean and moisturizing, and represents a huge part of the skin care industry.

Olive oil is reported to have antioxidant properties (vitamin E), which would be of use in the case of psoriasis, since free-radicals have been linked to psoriasis outbreaks.
