Blood blisters and cottonwood buds

This morning I was a little careless and gave myself a blood blister with a pair of scissors. If you've ever had a blood blister then you will know how painful these tiny little things will be. I am making a bunch of cottonwood salve today so there were a a lot of buds on the counter. Moments after I pinched myself, thus creating the blister, I picked one up and applied the bud and resins directly to the darkening area. Instantly the pain was gone and has remained so. And although blood had been forming under the surface of my skin, it's completely gone 30 minutes later. Gotta love cottonwood for first aid.
