When Bear was fighting an allergic reaction to plastic that manifested partially as scabby acne and then a swelling on his chin, we tried a number of different topical washes and solutions to help. It didn't go totallly away until after I removed his collar - which is made with a synthetic fibre - but one of the washes that did the best job was a boiled tea made from the herb pau d'arco. We started off with betadene washes but I found better results after the pau d'arco tea that I started to use that instead. I would make a fresh tea (boiled for several minutes) of pau d'arco root (available from most health food or natural food stores), leave the herb in the water as it cooled, and then was it was luke warm rinse his chin with the tea. He also enjoyed lapping it up, and as it is also used as a drinking tea with no reported toxicity (although lconsumption of large amounts can cause nausea), I would put some down for him as well.
There have been quite a number of tests down on pau d'arco as it is one of the herbs that is supposed to help with cancer so there is quite a bit of information available. Here is some information about it's use in North America (it is used internationally even though it originates in South America) :"In North American herbal medicine, pau d'arco is considered to be analgesic, antioxidant, antiparasitic, antimicrobial, antifungal, antiviral, antibacterial, anti-inflammatory, and laxative, as well as to have anticancerous properties. It is used for fevers, infections, colds, flu, syphilis, urinary tract infections, cancer, respiratory problems, skin ulcerations, boils, dysentery, gastrointestinal problems of all kinds, arthritis, prostatitis, and circulation disturbances. Pau d'arco also is employed in herbal medicine systems in the United States for lupus, diabetes, ulcers, leukemia, allergies, liver disease, Hodgkin's disease, osteomyelitis, Parkinson's disease, and psoriasis, and is a popular natural remedy for candida and yeast infections.

There have no reports of toxicity in human or in controlled lab testing on mice. The complete information is available here on an herbal database:
I have no hesitation in recommending it as it really did work with Bear. It is also relatively inexpensive as a little goes a long way. Good luck.
