Cedarwood:
antiseptic, relieves skin inflammation, bug bites
Cinnamon Leaf:
shows promise as a great-smelling, environmentally friendly pesticide, with the ability to kill mosquito larvae, according to a new study published in the Journal of Agricultural and Food Chemistry, a peer-reviewed journal of the American Chemical Society, the world’s largest scientific society. The researchers also expect that cinnamon oil could be a good mosquito repellant, though they have not yet tested it against adult mosquitoes.
