I personally believe what we call Adult De-wormer and Adult Longevity Spices are the 2 best worming formulas that exist on earth and nothing anywhere would even come close as far as a complete formula would go...both in 16 ounce syrup/tincture style formulas......seem to be practically perfected now....I do want to ad a few old time rare herbs from past history to the final mix someday, but the formulas are about as good as they possible could every be now.
They are potent, smell potent and loaded with herbal minerals as part of their preserving method, etc...Clark made de-worming popular..her 3 herb beginning (walnut-clove-wormwood)made her a forrunner to the public, while de-worming use to be popular back before the ama took over with chemical drugs.

Shelf life should be permanent!
Liquids have been taboo by most herbal companies, but now that herbal powders/capsules are on the fda hit list, I must wonder if the heral liquids will become popular again, because in general, the liquids don't need all the testing like herbal powders/teas do. Once made liquid properly, spoilage is not a problem.....a true tincture fro example should last well over 100 years.
