I have always grown Aloe Vera for skin emergencies like sunburn and have found that it is also beneficial for treating the itching and scaling of psoriasis. All you have to do is to split open a leaf from your plant and rub it over the effected area. The gel is rapidly absorbed by the skin and is cooling, so you can apply plenty and often. It stops the itching and for those who prefer you can by aloe gel juice from health food shops.
You may also like to Burdock as a home remedy for psoriasis. All you have to do is boil two cups of water together with one cup of Burdock, then lower the heat and simmer for half an hour. When cool strain, bottle and apply to the area affected several times a day, for fast results.
Eating an Avocado is known to be good for your skin, but next time you cut open an Avocado try rubbing some over the affected areas, as many people have found this works well for psoriasis.
