The recipe: take 100 grams of raw garlic, mashed as mud, add 150 grams of vinegar in a glass bottle, soak for a week and then prepare to use. If you suffer from gray finger (toe) nails, you can dip the affected finger (toe) into the garlic vinegar solution for 3-5 minutes, 4-6 times a day. Insist on 7-15 days, can be effective or healing.
The above formula, you can increase the amount, in addition, you can directly in the day of good soak, do not have to a week later, the other all right soak, do not have to limit the time, soak the longer the better, probably soak a month or two and so the new nails are all grown out on the good. If it is the foot, remember that it is best to previously worn shoes and socks are sterilized, boiling water, sun burst, socks simply do not good. In any case, you have to eliminate all the previous bacteria before, otherwise it will still be infected.
In fact, there are a lot of remedies, but this is the one I used, so I only recommend this one. I hope it works for you too.
