Ingredient Profile

Chinese Name薄荷脑
PinyinBo He Nao
Latin NameMentholum

Modern Research Perspective

Menthol activates sensory ion channels and has been studied for topical cooling, analgesia, airway sensation, and antimicrobial effects in experimental and human symptom studies. Effects depend on route, concentration, and formulation.

Evidence supports symptom relief in selected topical or oral contexts but not broad disease treatment. Irritation, bronchospasm in susceptible users, ingestion toxicity, interactions, and pediatric safety require caution.

Traditional Function

Menthol is pungent and cool. In traditional practice it is used to disperse wind-heat, clear the head and throat, and provide a cooling sensation. Concentrated menthol is distinct from whole Mint Herb and requires careful dose control.
