Neuroscientists at Northwestern University have made an amazing discovery about catnip, it repels mosquitoes and other insects. The active component of catnip (Nepeta catoria) is nepetalactone which stimulates a neuroreceptor called TRPA1. TRPA1 is found in most animals from insects to humans, and transmits pain sensation to the brain. TRPA1 can also be triggered by hot, cold, and irritants. <\/p>\n\n\n\n
The interesting thing is that when applied to humans as a repellant it does not trigger a pain response in the human, nor does it trigger pain in felines. In felines it triggers a different receptor involved in pleasure sensation. <\/p>\n\n\n\n
Work is underway to find an effective way to use nepetalactone in an easily applied skin vehicle to provide a non-DEET alternative for summer misery.<\/p>\n","protected":false},"excerpt":{"rendered":"
