I am afraid that pouring it straight on the wound without doing any systemic cleansing will drive them deeper into your body. Would recommend putting a drop or two of 35% food grade H202 in a glass of distilled water and sipping it slowly. Be careful because it can kill you if you drink it without diluting it. Work your way slowly up from a few drops to 25 drops three times per day. Go slowly and lower the dose if you get a headache, as that means your kidneys are working over time to eliminate toxins. The most I have been able to tolerate is 20 drops twice per day and I get a mega headache. Taking it internally will insure that you are driving them out of the body instead of inward. I have even put a few drops of h202 in a quart of distilled water and done an enema. Dead worms were in the toilet the next morning. So it does kill them.
