“The detection of spicy food is not done by neurotransmitter receptors in the brain but by chemical receptors at the periphery that respond to capsaicin, the naturally occurring chemical that makes chili peppers hot and painful. In an interesting twist on drug tolerance, capsaicin can be used as an ointment to desensitize and internalize receptors and relieve pain associated with conditions like arthritis and neuropathy.” — Indira M.
