Hi LymeMommy and welcome!
Years ago when I took Dr. Jernigan's botanicals there was 20% grain alcohol in them that made me nervous as I am a recovering alcoholic. I wanted to take his botanicals but didn't want to ingest the alcohol so I called up the Hansa Center (it had another name back then) and was told to put the droppers of each botanical I was taking (it was 2 different ones most of the protocol) in a glass of water and let the glass sit for at least 15 minutes. This way most of the alcohol would evaporate.
I did that and I didn't feel any "buzz". Believe me, I would have known it!
If you use any type of heat, you will destroy the botanicals (herbs).
Hope this helps,
Denise
