What to do against bruises?
The best herb against bruising is "Comfrey". An easy-to-find plants during the summer. You dig up the root, which differs, cut into slices, lay on the bruise and a bandage around. Helps perfectly. You can root after Schilling also dry and then grind. The thus obtained powder is thus usable throughout the year. This mix you with a spoon of olive oil and a few spoonfuls of hot water. This slurry on the bruise and first film for it, then a bandage. Also works very well with strains and with a sore back, is a whole affair on the back because it is a very sticky stuff but works incredibly well!
