People who suffer from chronic itching say it’s more unbearable than pain. I’ll never forget a 2008 story called The Itch in The New Yorker.
Chemical and Engineering News reports that a compound in the popular psychedelic plant Salvia divinorum was found to contain a compound that is found to provide itch relief to mice.
Salvinorin A, a hallucinogen produced by the Mexican plant Salvia divinorum, holds promise for treating itch and pain because it activates the κ-opioid receptor while avoiding the μ-opioid receptor, a sister receptor that’s been associated with opioid abuse.
Chemists have tried to synthesize salvinorin A so that they could alter the structure to sidestep the compound’s psychoactive effects while preserving its analgesic properties.
