**Senna** is a stimulant laxative herb, and this 500 mg capsule is made for one job: relieving occasional, short-term constipation — not daily wellness. Its active sennosides work by irritating the bowel lining to trigger a movement, which is why senna is an FDA-approved over-the-counter laxative with solid clinical backing for a few days of use.
The catch: the label lists 500 mg of senna leaf but never states the sennoside content — the standardized active that determines strength. Leaf potency varies, so you can't know exactly how strong each capsule is. The FDA target is 15–30 mg of sennosides daily, which whole-leaf products usually reach around 1–2 g.
Treat this like any stimulant laxative: occasional use, a few days at most. Regular daily use risks dependency — the 'lazy bowel' effect — plus cramping and electrolyte loss, and it's not appropriate during pregnancy or alongside diuretics or heart medications.
