Known as a relaxant, the scent of lavender has been recommended as a stress-buster. Peppermint oil also has long been touted as a natural pain reliever and used as a folk remedy to dispel headaches.
Some people think it prevents vein spasms associated with migraines.
Medical research has not shown any therapeutic advantage with lavender. Peppermint has a slightly better track record. As with most natural remedies, pregnant and lactating women are advised to stay away. The package also advises people experiencing epilepsy not to use it. Some people may have allergies to the oils, which could cause a skin reaction.
