Not all uses for senna have been approved by the FDA. Senna should not be used in place of medication prescribed for you by your doctor.

Senna is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Senna is not excreted into human milk. However, senna is a prodrug which is metabolized in vivo to the active sennosides (glucosides of rhein). Rhein is excreted into human milk in very small amounts. No adverse effects have been observed in nursing infants. The American Academy of Pediatrics considers senna to be compatible with breast-feeding.
