A chemical in sangre de grado known as crofelemer (SP-303) was approved as a drug by the U.S. Food and Drug Administration (FDA) for diarrhea in people with HIV/AIDS. It is also sometimes used for travelers' diarrhea and irritable bowel syndrome (IBS), but it has not been approved by the FDA for these uses. Sangra de grado supplement products have not been studied for these conditions.
Sangre de grado supplements are sometimes used for the common cold, upper airway infections, ulcers, and many other conditions. But there is no good scientific evidence to support these uses.
