I've been using 20 Mule Team Borax for a week now with 500mg of Magnesium and I'm almost fully psoriasis free. Dose 1 tsp of Borax in one liter of water to make a concentrate. Then take only 2 tsp of the concentrate and mix it into a glass of water. Drink that with food. I do it at breakfast. Be sure to take a 500 mg magnesium pill with it also, or the Borax WILL NOT activate. Borax alone will do nothing for psoriasis. You have to have the magnesium with it. Hope this works better for you. It's working for me. I'm actually stunned that I've had this stupid psoriasis all these years and it was such a simple fix. Summer time shorts here I come.
