One of the most effective things to do for psoriasis is to soak in bicarbonate rich baths for full body coverage. Here is an excerpt from Dr. Sircus' work showing the efficacy of this:
“For centuries, medicated baths have been one of the first lines of treatment for psoriasis. Even today, with sophisticated immuno- suppressive treatments available, Dead Sea salts and spa waters are recognized to be beneficial in the management of psoriatic patients.
To assess statistically the efficacy of sodium bicarbonate baths in psoriasis patients, thirty-one patients with mild-moderate psoriasis were studied. Almost all patients who used NaHCO3- reported a statistically valuable improvement. NaHCO3- baths reduced itchiness and irritation; in general, the patients themselves recognized a beneficial impact on their psoriasis, so much so that they have continued to bathe in NaHCO3- even after the end of the study.”
In addition to sodium bicarbonate, spraying magnesium chloride on the skin will also help to greatly reduce psoriatic lesions. Use the magnesium spray liberally as long as your kidney function is good. You can also combine the magnesium and sodium bicarbonate together in baths. Use about 1 lb. of sodium bicarbonate to start and 1-2 cups of magnesium bath flakes to start out with and then increase the amounts depending on your tolerance. Increase or decrease depending on your own reaction and check your pH daily to make sure it doesn't go above 7.4.
It is necessary to get to a more alkaline pH and so lifestyle dietary changes need to also be a part of this therapy.
For iodine dosages and further information you will need to obtain a personal consultation with Dr. Sircus. Other supplements can be added, such as vitamin C.
