Cistus is more potent than any other agent known for biofilms. Crosses the blood-brain barrier and is 100% absorbed in the gut. It is antiviral. Can rebrew the tea 4 times. Whitens the teeth (also a biofilm which causes yellow teeth), body fluid smells and odors reduce." -- Dr. Klinghardt

"One of the big hits at our retreat with Dr Klinghardt in the summer 0f 2010 was Cistus Tea, a pleasant tasting loose tea with a mild, berry-like flavor. In Germany, dogs who were given a daily dose got 1/100th the tick bites of dogs who weren’t. Since I live in one of the worst areas in the world for ticks and Lyme, and spend about an hour a day walking with my little pal Lucy in the woods, I was very eager to test it out on us both. What I find is that the ticks don’t seem to like us any more, and yay for that!
If using it consistently, I no longer find ticks on either of us, and many of my clients have had the same experience. And that’s a pretty dramatic statement. After all, we tromp in the woods four times a day, and Lucy has her nose and paws in all sorts of leaves and brush where ticks love to hang out"
