Barberry (Berberis vulgaris) has a long history of use in traditional medicine systems, particularly in the Middle East, Europe, and parts of Asia. Historically, barberry has been used as a bitter tonic to stimulate digestive secretions and enhance appetite, especially in cases of deficient appetite or digestive sluggishness. The bitter taste of barberry, due primarily to its alkaloid content such as berberine, is thought to promote the secretion of gastric juices, thereby aiding digestion and improving appetite. Traditional Persian and European herbal texts reference barberry’s use for “weak stomach,” “poor appetite,” and “digestive complaints.” Although modern clinical trials specifically evaluating barberry for appetite stimulation are lacking, the traditional rationale is consistent with the broader use of bitters in herbal medicine to encourage appetite in those with deficiency.

Scientific validation for this particular use is limited; most contemporary research on barberry focuses on its antimicrobial, anti-inflammatory, and metabolic effects rather than its impact on appetite. However, the traditional use and the pharmacological rationale (i.e., stimulation of digestive function by bitters) give moderate historical support for its application in cases of deficient appetite. Thus, while there is a strong traditional basis for using barberry as an appetite stimulant, robust scientific evidence is not yet available to confirm its efficacy for this purpose.
