Working against bacteria and viruses
Humans need a strong and healthy immune system to defend the body from the possible damaging effects of bacteria and viruses. Extract from fresh olive leaves can be extremely potent in protecting the body from microbes. It is the pungent components found in the leaves or polyphenols that were found to be especially effective in preventing damage caused by bacteria. A drug company study found olive leaf extracts to be useful in the treatment of parasitic protozoan, viral, and bacterial infections.
