There are actually quite a few foods/herbs that are antiviral.
Elderberries are an excellent antiviral for the flu virus.
Other natural antivirals include garlic oregano, coconut oil, echinacea, onions, ginger, skullcap, cat’s claw, etc., etc. Many of these are also antibacterial and antifungal as well.
God’s medicine is pretty amazing. He made sure that every location will grow herbs and foods that will treat any illness.
The key with natural stuff is to take it in a high enough quantity and frequency to be effective. You can’t drink one cup of elderberry tea, for example, and expect to get over the flu with just that.
There’s TONS of info available, though. It’s just a matter of reading and learning and applying. I think it’ll be to our benefit in the future to know how to self-medicate with foods and herbs.
Don’t forget one of the biggies, curcumin from turmeric or curry, great for pain and inflammation, and bromelain from pineapple, again great for pain and inflammation. Both thin the blood and can interfere with clotting so people with bleeding disorders or already on coumadin, warfarin, NSAIDs, etcetera should exercise caution.
