My house mate told me a trick that works wonders. I mince up four garlic cloves. You can also mash them. I put the minced garlic in a glass of grapefruit juice. Wait about twenty minutes. Then drink it. The grapefruit juice takes away the strong garlic taste. I've used this when getting flu or cold and it works every time. I had a bad cold coming on and had to do it three days in a row. I did this before going to bed. Each day I woke feeling great and the night started feeling sick again. So I would repeat. So simple and so good. I only wish I had known about this years ago.
