most all of the formulas are ones i don't make and follow medicaly style theories depending on the action of each herb.....none the formula should be hard to make "if" many of these old fashion herbs can be located and this medical author used none herbal products as well with the herbal products in a manner to actual create fast/medical type corrections of the human mineral balance...not something i ever got into, but a very fasinating study of herbs; i think it would be kool to have a method where each person made the formula that the auhtor instructed and then move onward to the next and the next, etc....
