If the Black-Walnut is not in liquid form, like in parastroy, it does not contain alcohol. Alcohol is a base used in some liquid extracts. There are some glycerin- based extracts of Black-Walnut that you can find in a health store or on an online herb site like iherb.com. If the ingredients don't list alcohol, there shouldn't be any included, and most will list that because of the possibility of administering it to children and severe drug interactions and company liability would be very high in that case. If you want to be on the safe side, though, just get a powdered form of the herb. Parastroy is one of them. No alcohol, period.
