Catnip

Catnip is not just a happy-time elixir for cats. Chewing on catnip leaves can help toothaches. It also makes you sweat, which can lower fevers. It is also known to be a mild sedative to humans. Some people use catnip oil as an insect repellent. Some research suggests that it repels mosquitoes 10 times more effectively than DEET.
