The original herb mix is Burdock Root - 16 parts, Sheep Sorrel - 1 part, Turkey Rhubarb Root - 1 part (or native Rhubarb root - 2 parts) and Slipperly Elm - 4 parts. This is brewed in a special way and can be made to produce liquid amounts as needed. Preventive dose is 2 ounces per day - treatment is 4 punces per day (taken twice per day) for 12 weeks.
I do have the herbs and I can help you make your own - but you'll have to brew it yourself - it is not a hard process, but you have to follow the exact method. Email me and let me know if you are interested. rg@humaworm.com
If you decide to go another route - just remember, the 4 herbs are all that are really needed.
