I was told by a friend that she knew someone that drank Vanilla Milkshakes to get rid of her migraines, well I basically laughed this off figuring it was an excuse to have a milkshake and didn't give it another thought. After having a 5 day extremely bad bout of migraines where nothing was working, I told my husband I'm going to go get a Vanilla Milkshake, which I did and I was shocked that my migraine went away. I had had 5 days of non stop migraines and one milkshake cured it. So a googled it and this is what I learned.
For many people, vanilla may be the key for eliminating headaches. Vanilla extract contains eugenol, an essential oil that has antiseptic and analgesic properties and that helps unclog blood vessels
One headache sufferer reported that nothing had worked for his constant headaches of 40 years until he turned to vanilla. He drank a tablespoon of pure vanilla extract in 8 ounces of water before going to bed, and the next morning the usual headache pain was only half its normal intensity. Two days later it was gone completely and hasn't returned in over a year.
