Every time people ask about arnica, I have to post. Used it for years and always will. Yesterday I was rushing into a room and banged my arm in the doorway, wow it hurt so much, immediately got my arnical gel and slapped it on, minutes later no pain. There was slight bruising for a few hours later but today nothing, no bruise, signs or pain and it hurt so much when it happened I nearly cried. Now Propolis on the other hand, I really wanted it to work but it doesn't do much for me at all, I've tried it on lots of different ailments suited for it and had hardly any effect and on different people too. So Yes to arnica but No to propolis for me.
