Frangula purshiana (emodin/cascarosides)

Limited Evidence evidence: moderate

Scientific Summary

Cascara Sagrada is the dried bark of the Frangula purshiana tree, harvested from wild Pacific‑Coast populations. It is primarily used as a natural laxative to relieve occasional constipation and may support digestive health. Because it can cause cramping, diarrhea, and nausea, it should not be taken during pregnancy, for prolonged periods, or without consulting a healthcare provider, and it can interact with other medications.
