I do not recommend mixing zinc chloride with bloodroot. It will leave huge scars on the skin and the disease often comes back. My skin itches around the scar on my neck to this day. And now I am using other herbs on my neck because I have a big enough scar there already.
There are much better ways to deal with wars and moles in my opinion. If I had it to do over, I would cleanse internally with bloodroot tincture exclusively (no zinc chloride) for several months, and then have a dermatologist remove the skin spots.
I have no idea where people are getting zinc chloride. I wouldn't ever use the stuff again. It is very barbaric what that stuff does. And it is excruciatingly painful. Your skin feels like it is on fire for weeks. Not to mention that it is very time consuming and tedious to care for the wound properly. And if you don't do it right, the thing won't heal.
It took for months for me to get the wound on my neck to heal up.
