Houttuynia cordata (chinese lizard tail)
Has antiviral properties and has been found to inhibit the herpes viruses replication. It helps prevent mast cell degranulation which would prevent high histamines. It inhibits more inflammatory cytokines then NSAIDs do. It has been found to significantly reduce Sars-Covid infection. It has been shown to help prevent obesity and high triglycerides. It improves the detoxification of xenobiotics which have been linked to many types of cancer and hormone issues. It has been shown to help prevent insulin resistance which causes type 2 diabetes. The eye drops have been found to be effective against dry eye disease. It has been found to help with certain types of cancer like prostate cancer. It has very potent antioxidant properties.
I could find no valid side effects except when it has been directly injected into the blood stream. Not a wise move. Also I found sites sponsored by the pharmaceutical industry that made ridiculous claims and there was no science to back them. You could see the pharmaceutical ads all over the websites making the claims I searched many websites on the toxicity of of houttuynia and found nothing worth noting.
