A natural medicine doctor who sees and treats a wide variety of mold patients, recommended Nature’s Way Pau d’arco supplements. I take 3 capsules twice a day. I noticed that the constant dull headache I have always had, went away the 2nd day. I think it’s very effective, but who knows which of the multiple treatments did it. (exercize, infrared sauna, epsom salt baths, all veggie diet high in sulphorafane)
