“I followed the directions and sprayed it lightly on a test area first to see if there was a sensitivity issue. I dialed it down to the lowest possible setting. No reaction so I used it 2 days later. I sprayed a light amount onto my own hand and just did a light dab on my horses sheath. The next day his sheath was swollen to 3 times it's normal size! I have washed it with mild soapy water, given him bute and cold hose it several times a day and it's still very swollen. He has never had this kind of a reaction to anything else I've ever used before. So people need to be warned that this shouldn't be put on bare skin as it might cause a huge issue.”
