Is there a natural antibiotic i could find at a health food store?
Garlic is a really good natural antibiotic. I have tried fresh garlic and odorless garlic tablets, and only the fresh garlic worked for me. You have to eat a ton of it (I was eating 3-4 cloves 3x per day), and you’ll reek like garlic for a while, but it could be effective. Also for sinus problems, neti can provide a lot of relief. However, if you’ve already taken antibiotics, chances are the bacteria left in your system is really strong, so unfortunately you may need something stronger. If this has been a persistent issue, I’d try to see a naturalist doctor, or at least a chat with the person at the health food store.
