Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Parsley (Petroselinum crispum) has a long history of use in traditional medicine, including applications as a digestive aid and mild laxative. In various cultures, parsley tea and infusions have been consumed to relieve digestive discomfort, bloating, and, occasionally, to support bowel movements. The rationale behind this traditional use lies in parsley’s content of volatile oils and compounds such as apiol and myristicin, which are believed to mildly stimulate the digestive system and potentially promote peristalsis.

However, scientific evidence to substantiate parsley’s efficacy for treating constipation in adults is very limited. While parsley does contain dietary fiber, which can contribute to regular bowel movements, the quantities typically consumed in culinary or herbal preparations are usually too small to have a significant laxative effect. Only a handful of preclinical studies and anecdotal reports suggest a possible mild benefit, but there are no robust clinical trials supporting its use for constipation. Thus, its use for this purpose remains rooted primarily in traditional practice rather than modern evidence.

In summary, parsley’s use for constipation is traditional, with minimal scientific backing. It may offer mild benefit as part of a diet rich in fiber and fluids, but it should not be relied upon as a primary treatment for constipation.
