My four and seven year olds recently got blisters that grew quickly and scarily. I now believe this was impetigo because of its appearance and aggressive progression, but at the time all we could think of is poison oak. We purchased Hylands Homeopathic Poison Ivy / Oak Remedy, a sublingual tablet and followed the directions. Interestingly, it has worked amazingly well! Within maybe two days the sores were visibly smaller and continued to clear until gone.
My friend's son caught it from my son and they went the antibiotic route. Their son's sores returned but with this homeopathic remedy it has not come back for us. The formula on the back is listed as: RHUS TOXICODENDRON 6X, HPUS; CROTON TIGLIUM 6X, HPUS; XEROPHYLLUM 6X, HPUS; IN A BASE OF A LACTOSE USP.
