I. The snails used are from the river, I don't know if there is such a thing as river snails, we call them screws here. Just use the net to the river to fish. The best fishing kind of big, out of the mucus to be more, the effect is also better. If you don't have the conditions to fish for yourself, the barbecue store has the kind of small snails used for cooking is also OK, and there may be big snails for sale in the city, right?

Second, the snail with a toothbrush clean, put into the pot with water for a few days, let it spit out the dirty things. Change the water several times a day, because it has to defecate and spit out the mud. Be careful to cover the lid, the snail will climb out on its own, climb to which corner may not be found.

Three, raise the clean snail with the back of a knife and pat, carefully remove the hard shell, pick up the meat inside, put it into a small bottle, add the right amount of ice chips, put it in the refrigerator (snail meat is easy to be bad, a snail can be used for two days). It can be used after two hours. Use a cotton swab dipped into the juice of the snail meat mixed with ice chips and apply the medicine directly to the affected area. Rub five or six times a day. You will feel that the affected area is getting better day by day until there is no pain, itching or swelling. For minor patients, if you can pay attention to life, diet and exercise, etc., may be cured; for a little serious like me, it is easy to repeat, but with this method, you will give yourself peace for a while, which is better than taking medication on the effect.
