Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Dandelion (Taraxacum officinale) has a long history of use in traditional herbal medicine, particularly in Europe, Asia, and North America. Traditionally, dandelion root and leaf have been used as a mild laxative and to support digestive health. The rationale for its use in constipation is largely based on its reputed ability to stimulate bile production and promote mild diuresis, which was believed to encourage regular bowel movements. Folk medicine texts from various cultures cite dandelion infusions or teas as remedies for sluggish digestion and occasional constipation.

Modern scientific studies on dandelion's effectiveness for constipation in adults are limited. Some in vitro and animal studies suggest that dandelion extracts can increase gastrointestinal motility, but high-quality human clinical trials are lacking. The plant contains inulin, a type of prebiotic fiber, which may help support healthy gut flora and indirectly improve bowel regularity in some people. However, the direct laxative effect and its clinical relevance in treating constipation have not been robustly demonstrated in controlled studies.

In summary, while the traditional use of dandelion for constipation is well documented, scientific validation remains weak. The evidence base is primarily historical and observational, with some plausible mechanisms but insufficient rigorous clinical data to strongly support its use for this purpose.
