This has been such a relief for me, as I'm naturally prone to sinus infections. Here you all go:
Combine one crushed/diced garlic clove that has been sitting out for 15 minutes (allows allicin to accumulate) with one teaspoon raw honey and ½ teaspoon cayenne pepper, and mix together.
Take appox ¼ of the mixture and swallow it, washing it down with warm tea or water. Finish the mixture.
Do this 2-3 times daily, every day while symptoms persist, and a few days afterward. Note: you can also sprinkle it on food and take it that way, if you find that more palatable. Ideas include pasta and pizza---skip the honey and put the garlic/cayenne mixture in pasta sauce or top a slice of pizza with it. Finish with tea and put the honey in that instead. If you don't have raw honey, I've used organic honey, and that worked just fine.
