I make a body butter with shea butter, coconut oil, mango butter,avocado butter and cocoa butter. I put 1c of dried yarrow and 1c of dried plantain in a qt jar, fill the1 liter/quart canning jar with the warm body butter and put it in a crock pot for 4 hours. Strain, put in 1/2 pint jars and let cool. It is analgesic, antiseptic, anti bacterial and stops bleeding, fosters healing. Works great, and can use it on broken skin. I sometimes add arnica, but then it is not usable on broken skin. You could eat it, non toxic.
