AH try to research Mullein oil.
Also, a study from the Portland University Oregon, I believe it was through the nutrition studies performed, found that the enzyme in garlic, the enzyme making it have active constituents for better health, actually is disintegrated via heat. However, they found that first crushing and waiting five to ten minutes prior to heating, activates the enzyme needed and then withstands the heat! So I always ask, how was this prepared. Its very easy to make your own to ensure the proper process and the best health benefits! Other than that its just flavor, which I love garlic too!!
Gosh I'm sorry it was so long ago and I am trying to find the article for you. Its very interesting. When I find it I will post it.
