A friend has a big reddened scratch on her wrist from one of her chickens' claws, so I gave SSKI topically, 2-3 drops. She said it stung at first, and after 20 minutes the redness had reduced some. She felt heat radiating up her fingertips in the one hand for 20 minutes, and was a little hyper, and then very relaxed. hyper for 30 mins after the drops, relaxed afterwards.
Very nice to see inflammation go down so swiftly. She was very happy about the sensation of heat because of usually having cold hands.
