Source of validity: Traditional
Rating (out of 5): 3

Sichuan pepper (Zanthoxylum spp.), known as "Huā Jiāo" (花椒) in Chinese, has a long history of use in Traditional Chinese Medicine (TCM) to stimulate appetite, particularly in cases of deficiency (poor or diminished appetite, often associated with weak digestion). According to TCM theory, Sichuan pepper is warm and pungent, able to dispel cold and dampness, promote the flow of Qi (vital energy), and harmonize the Stomach. Classic TCM texts, such as the "Shennong Bencao Jing" and later materia medica, describe its application for abdominal fullness, lack of appetite, and digestive sluggishness—conditions often interpreted as "Spleen and Stomach deficiency" in TCM. Practitioners have used it to season food and as an ingredient in herbal prescriptions targeting appetite loss and digestive complaints.

Modern scientific studies on Sichuan pepper's efficacy for appetite stimulation are limited, but its pungent components (such as hydroxy-alpha-sanshool) are known to activate sensory nerves and may increase salivation and gastric secretions, potentially aiding digestion. However, most evidence supporting its use for appetite deficiency remains rooted in tradition and empirical observation rather than rigorous clinical trials. Thus, while the historical and traditional basis is strong, scientific validation is still lacking, justifying a moderate evidence rating for its traditional use in treating deficient appetite.
