Dr. Christophers book doesn't tell you how much parts of herbs to use. It does state the herbs in each formula.
I am studing an herbal course that does tell you the amounts. I can look it up and post exacts if you need it. From memory I can tell you that its equal parts of each herb except 2 parts of cascara bark. Grind herbs or buy already powered and put them in an oo capsule or you can combine with, I think, one part of slippery elm and add a bit of water and roll into pills and let it dry for a few days and take it that way if your apposed to using capsules.
