“From a traditional Chinese medicine perspective, although Houttuynia cordata extract (HCE) contains numerous phytonutrients and exhibits antioxidant activity, excessive doses of HCE can pose risks to organisms and lead to death.” 1
We have proven that huge doses fail to kill Bartonella in humans, yet LL MDs say it works based on a test-tube study. No human research as we did 20 years ago. But no one was harmed by our huge dose human trials.
But please do not think this herb is of no worth. In one science article, over 15 fascinating benefits were summarized. 2
