In the past 30-40 years fumaric acid has been used to treat Psoriasis and many reports have indicated there is a problem of its becoming toxic in the liver. Almost everything could become toxic, even water, if a person did not use common sense.
It was about 1969 when a fellow named Schweckendiek provided some information about fumaric acid and the treatment of psoriasis.
But maybe I am getting ahead of myself. If you currently have psoriasis then you know about the disease, but if you do not and your notice people with some sort of reddish rash on their arms and legs, then that person most likely has a psoriasis condition. It is not easy to live with.
Psoriasis has been determined to be a immune-mediated disease and sometimes effects not only the skin but also the joints. The National Institute of Health (NIH) says up to 8 million Americans are affected.
When you see someone with psoriasis you may think it is "catching". It is not. The lesions may look ugly and sometimes because of scratching (they itch) you may see scabs and possibly broken skin. It is not contagious.
Psoriasis has been around for along time, the Greek Physician, Hippocrates spoke of it. That could make it a centuries old disease. A Roman author Cornelius described the condition. After all this time the cause is still unknown and a total cure is rare.
The total surface skin of a human being is replaced every 28-30 days, normally. With a person that has a psoriasis condition this cycle is reduced to 7-10 days.
There has been some interest in activated vitamin D (Rx only) that reduces the growth of skin cells and also some of the itching. It sometimes takes up to one month to see any effective improvement. Of course the sun produces vitamin D and the Dead Sea area in the middle east has grown very popular with people with a psoriasis condition. The water of the Dead Sea is known for its heavy content of minerals as well.
Do not try to take vitamin D as a supplement as the body only needs a certain about and any excess will be eliminated by the body.
Fumaric Acid was mentioned above as a possible treatment. There is a lot of controversy over whether this will have a positive effect on psoriasis before it becomes toxic to the person. The Fumaric Acid that has been used to treat psoriasis is normally referred to as FAE's. This treatment therapy has been used in Germany since the mid-1990's. Reports vary on the success of this treatment protocol.
It seems, as usual, what will work for one person will not work for another. One just has to experiment with all suggested treatments until one is found that is successful, Fumaric Acid together with 20 minutes of full sun exposure to the psoriasis affected area just may be the answer to some improvement in the condition.
