I read years ago (can't remember where) that mimosa hostilis is used in a skin healing ointment/solution. That it has cellular regenerative properties.
About 4 1/2 years ago I got second, third, and fourth degree burns (some muscle burned) on about 1/3 of my right hand, on the palm and the fingers. It was horrible. I will try to keep a long story short. I Got burned, went to the hospital. Doctors in Spain attempted to ruin my life because I did not want to stay in the hospital( I was considered a dirty hippie...which at the time i was...lol
). They told me if I left the hospital I would never use my right hand again. They attempted to make it happen by wrapping bandage over my burns without ANY ointment or buffer. I did not notice as they were doing it, as I was a little out of it. About a day later when an incredible amount of itching started, I realized I could not get the bandage off. Well, I realized there was no other way to do it except rip it off. I proceeded to soak my hand in h2o2 water for about an hour to soften it up. Well the bandage came off, slowly, but was a horrible experience as it was bonded to skin, half skin and muscle, and had tried to scab.
Over the course of the next couple of days I used mimosa soaked in water to apply to the burns. When applying it created the most painful stinging sensation I can image. This was alternated with fresh Aloe vera. I couldn't move my fingers for about a month. I have full functionality in my right hand now..It took a few months though. And no scars. There's a couple places on the tops of my fingers where the skin is very slightly discoloured, but only I can tell, and only at certain times.
Take away from it what you will...
