My mother swore uphill and down that garlic was healthy, partly because it thins the blood. She did insist, though, that it had to be fresh and raw, not cooked or processed.
With all the summer-time bugs, it occurred to me to take another look at vampire legends that garlic repels blood suckers. Even the thought of swallowing raw garlic whole I found a little daunting, so I made a variation on a pill.
I mixed 1 teaspoon of whole wheat flour with 1/4 to 1/2 teaspoon water to make a tiny ball of dough. Then I took 1 small clove of fresh garlic (can use 1/2 of a medium-size clove or 1/4 of a large clove) and wrapped it in the dough ball. Swallowed it whole and washed it down with a glass of water.
The repellence appears to be quite effective.
