Cure for oral herpes

Posted by iHerb Customer on November 24 2017 | Verified Purchase

I was able to use a combination of Olive Leaf from Natural Factors and Astragalus Supreme from Gaia Herbs to cure my oral herpes permanently. To help with the process I also purchased organic virgin coconut oil and an Elderberry cocktail from a local farm. I would wash my face and lips with a tea tree oil Zum bar every couple of days. Lastly I also paired it with Christopher's parasite syrup to clean out anything that might be suppressing my immune system. The only thing I was missing that might of helped was to take Vitamin C. The Prescription for Nutritional Healing by Balch recommends 5,000 to 10,000 mg daily of esterified or buffered Vitamin C combined with 30-60 mg daily of bioflavonoids in divided doses.

Thanks for your feedback!

It works!

We take this when we start to feel like we are getting a cold, sore throat, or been around someone who was sick. It helps our bodies fight to get and stay healthy.

Thanks for your feedback!

I started taking this and liked it very much, I had previously bought Now Olive leaf and used it, I didn't feel better ever....then I found out where they get most of their herbs!!!! China! I'll not buy anything else from Now.
