The book method for curring HIV is fine, but I make it stronger and I also make a formula with fresh Echinacea Rt. too!
I prefer to fill what ever your vessel is to the top with leaves. Fill with your homemade distilled water. Heat to about 150 and later back to a low simmer. Leave on stove at least 3 days. Start using, but leave on stove and strain as you use. For a problem, drink 1 quart per day for at least 2 gallons.
I may simmer Olive Leaf for 1-2 weeks when making formulas with it and also use the pure tincture and mixtures there of, I use Olive Leaf in all liquid and powder formulas. The same goes for Oregano oil or water.
I sell the pure and the Cass version of a 12-1 mixture. The pure is for the self-experimenter for sure, but a life saviour.
