ive just tested one capsule of that boswellia suplement i've mentioned (it contained not only boswellia but other antiinflamatory extracts as well) and it turned black as a coal. will reconsider boswellia if i will be able to find out some non starchy capsules.
Try to find this brand: "Pure Encapsulations"
