What is a good remedy for psoriasis

I have a severe form of psoriatic arthritis. I have come on a RX that alleviates the pain of the arthritis, but my skin is in very bad shape. ointments and creams have not helped. And we are talking about VERY expensive RX ointments. Any home remedies anyone has tried for extreme conditions that have worked?

With regular doses of intense sun, 95 percent of psoriasis sufferers improve. It's the ultraviolet waves that fight psoriasis, and the UVB rays work the fastest. But there's a catch-22. UVB's are also the ones that give you a sunburn and run up the risks for skin cancer. They can also cause psoriasis sufferers to break out in previously unaffected areas.

There is, however, an out. Sunscreen. "The benefits of sunbathing can outweigh the risks of skin cancer and spreading psoriasis if you use sunscreens on the places where you don't have psoriasis and only expose the affected areas to the full force of the sun.

Get yourself a small UVB sunlamp to treat patches of psoriasis. You may prefer the UVA light found in tanning parlors, but it's weaker and needs much more time to work.

Over-the-counter coal tar preparations are weaker than the prescription versions but can be effective in mild psoriasis. You can apply the tar directly to the plaques or immerse yourself in tar bath oil and treat your scalp with tar shampoo. Since even the OTC tars can stain and smell, they're usually washed off after a certain amount of time, but some kinds can be left on the skin to enhance the effect of sunlight or UVB treatments. "Tar makes you more sensitive to the sun, so be careful.
