In Chinese Medicine the eyes and nails indicate the health of the liver.
I recently found out about Olive Leaf Extract. It is a wonderful product used for centuries. It is antibiotic, antimicrobial, antifungal, antiviral, etc. etc. Solary is a good brand take one cap. twice a day per bottle instructions. After 7 days parasites will come out in the bowel. I just got the book Olive Leaf Extract by Dr. Morton Walker. You can get it and the product at East Park Research in Nevada. call: 1-800-345-8367. They also have a website. Put the name in your search engine. I don't have it at my fingertips right now.
Good luck to you. You will never have another cold or flu.
