Evidence notes
Cascara sagrada has long historical use and established pharmacological activity as a stimulant laxative. Evidence is solid for short-term constipation relief, but B rather than A due to limited modern RCTs and significant safety concerns limiting research. FDA recognized it as an active laxative ingredient, though it has faced regulatory restrictions.
Grade B: Some human trials support key claims; further confirmation needed.
