What are aloe and cascara sagrada?
Aloe, here meaning the bitter latex from the leaf, and cascara sagrada, the dried bark of a North American buckthorn tree, have long been used in traditional herbal preparations for their effect on the bowel. In modern terms they are known as stimulant laxatives, because they stimulate the bowel to move. The NHS describes stimulant laxatives as medicines that usually work in 6 to 12 hours.
What do regulators and medical sources say?
In 2002 the US Food and Drug Administration issued a final ruling that aloe and cascara sagrada are not generally recognised as safe and effective as stimulant laxative ingredients in over-the-counter drug products, citing inadequate safety data. See the Memorial Sloan Kettering summary. A Natural Medicines database monograph lists cascara as possibly safe when used orally for a short time, possibly unsafe long-term, and notes concerns such as electrolyte loss and potential interactions with some medicines. A related stimulant herb, senna, is described by the NIH LiverTox database as recommended for short-term use only.
Possible risks to know about
- Diarrhoea and cramping in some people.
- Fluid and electrolyte loss if used too often or for too long.
- Dependence if stimulant products are used regularly.
- Interactions with some medicines, so ask a pharmacist if you take any.
- Pregnancy and breastfeeding: cascara can pass into breast milk, so avoid unless a doctor advises otherwise.
The NHS also says that using laxatives too often or for too long can cause problems.
