Hi
I love Tiger Balm, have been meaning to get some for ages but finally did and I love it. I used it on a pulled back muscle and it got rid of it over about 24hrs, it is amazing stuff!
THere are 3 tyoes, yello (or clear) red and black, they can be mixed but not the red and black. I have known about it for years as my old Kung Fu master used it when doing massage! The red type is great for muscle aches etc! not sure about the other two.
Check in moss pharmacy as well as they sell it in there! or else you may have to ask in boots as some don't sell it!
Good luck
