Hi AB, That is a great question. I had the same thought when I was making a formula containing Lobelia too. When I back tracked on Lobelia, Doc said ideally he would use 3 parts vinegar and 7 parts hooch with 1 part Lobelia which also made me wonder so I will follow this post for the final answer 🙂 What I decided to do is keep to the formula as it was in a group already, therefore diluted in concentration by the other herbs. My tincture is still macerating so I will be interested to see what comes from this inquiry. Thanks for asking.
