Specific substances such as Menthol and Camphor are higher in percentage that is 2.6% and 4.73% respectively,1 they attenuate the excitability of nerve membranes and of the specific itch mediating C-fibers and A-fibers.2 Both substances act by attaching to the transient receptor potential (TRP) receptor, but the main mechanism of action by which topical menthol reduces pruritus is by attaching onto the cold receptor TRPM8 which then goes and reaches the A-delta fibers and hence giving a cooling sensation.2 While camphor attaches onto the warm receptor TRPV3.3 Furthermore, menthol also helps in providing general anaesthesia by being a positive modulator of GABA type a receptor.
