1. Overview
Bò Hé (薄荷) — Mentha haplocalyx — is known in English as Chinese peppermint / Field mint. It belongs to the category of Herbs that release the Exterior — cool and acrid in the Chinese Materia Medica and is used in Chinese herbal medicine as a component of classical herbal formulas and tailored prescriptions.
I prescribe Bò Hé as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan. Herbs are always combined with other herbs selected to match the patient’s individual TCM pattern. Online consultations are available for patients who cannot attend my clinic in person.

5. Modern research
Mentha haplocalyx (Bo He) is the Chinese mint species used medicinally, closely related to but distinct from European peppermint (Mentha piperita). Key bioactive constituents include menthol, menthone, menthyl acetate, flavonoids and rosmarinic acid. Research confirms antiviral and antibacterial effects, anti-inflammatory activity via COX-2 inhibition, analgesic properties (menthol's TRPM8 receptor activation), antispasmodic effects on smooth muscle relevant to IBS, and significant antipyretic effects. Bo He is added to formulas in small quantities (1-3g) near the end of cooking to preserve its volatile oils. The combination Chai Hu + Bo He is the core Liver-spreading element of Xiao Yao San.
6. Cautions and contraindications
Use in small doses only (1-6g) — large doses cause excessive sweating and deplete Body Fluids. Avoid in Qi deficiency with spontaneous sweating. Avoid in Yin deficiency. Add near the end of cooking raw herb decoctions to preserve volatile oils.
Important: Chinese herbs should always be prescribed by a fully qualified herbalist who is a member of the Register of Chinese Herbal Medicine (RCHM). Never self-prescribe Chinese herbs without professional guidance. Dr (TCM) Attilio D’Alberto is a member of the RCHM with over 25 years of clinical experience.
