I don't get many cuts and scrapes, but tea tree oil is good. I love the smell of that stuff. You probably can get it if you have legit reasons for buying it, say hairdressers etc, but you ask for certain stuff at the chemist, you get interrogated. I got looked at suspiciously and asked questions when i asked for ketone stixs, still not sure why, apparently used for some illicit reason. I did get them in the end, but it was embarrassing, so don't like asking for anything remotely suspect.
When there was some terroist bombs a few years ago, apparently they got small amounts at different places, to make bombs. So apparently we are all potential terroists now. LOL. To be honest i haven't actually asked for it, but it is just what i've heard.
