Yes I have used humaworm, and the Amish formula too. They both work, but are a little too expensive for me. I buy bulk herbs by the ounce at the local herb shop and can get wormwood for $3.50/oz. I also like to mix and match and throw in something new every time to diminish the chances of developing a resistant species.
I like to marinade the herbs in brandy and put the tincture in an enema. Woo hoo! Helps with the anxiety.
