Synopsis

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

Phenolic acids, a class of plant-derived compounds found abundantly in foods like coffee, fruits, whole grains, and vegetables, have a long history of use in traditional herbal medicine systems for supporting digestive health. While not typically referenced as isolated compounds in ancient texts, many plants rich in phenolic acids—such as certain berries, artichokes, and medicinal herbs—were traditionally recommended for relieving digestive discomfort, promoting regularity, or stimulating appetite. These traditional uses are largely attributed to the antioxidant, anti-inflammatory, and mild antimicrobial actions of such plants, which may help soothe the digestive tract and improve gut function.

Scientific studies on phenolic acids specifically for digestive improvement are limited and mostly preclinical. Some animal and in vitro studies suggest phenolic acids may positively modulate gut microbiota, reduce intestinal inflammation, and protect against oxidative stress in the gastrointestinal tract. However, robust clinical trials in humans are lacking. Thus, while traditional use of phenolic acid-rich plants for digestive complaints is well-documented, direct scientific validation remains preliminary. The evidence rating is therefore moderate but more heavily weighted toward traditional use rather than rigorous clinical proof.
