Nerve elongation inhibitor, skin sensory hypersensitivity inhibitor and marker for detecting skin sensory hypersensitivity

摘要

Provided are a nerve growth inhibitor and a cutaneous-sensory-irritation inhibitor, with which dermal hyperesthesia and nerve extension based on newly found nerve extension mechanisms can be effectively inhibited. This nerve growth inhibitor or cutaneous-sensory-irritation inhibitor comprises one or more selected from: (1) a specific flavonoid; (2) a tannin; (3) chlorogenic acid; (4) a specific stilbenoid; and a glycoside or a pharmaceutically acceptable salt of (1)-(4); or (5) a specific crude drug extract; and (6) a walnut polyphenol.
