Desert Harvest produces an IC safe form of aloe vera. I have read research that indicates that aloe vera has a positive affect on mast cells. It is important to take aloe vera in capsule form and avoid aloe juice as the juice is often preserved with citric acid.
Desert Harvest has reviews and testimonials from IC patients who have improved their symptomology by taking aloe. Personally, I tried it years ago and am interested in trying it again. I remember thinking I had experienced a reduction in pain but at the time I was less well versed on the diet and perhaps now I would have even better success. Let us know your experiences if you have tried aloe.
