クレーマ ‘A’

I bruise easily and have never had arnica help me in any noticeable way. Two weeks ago, I hurt my upper arm so badly, I knew I would be living with the tennis-ball-sized purple bruise for weeks.

I was buying something on this site and read the reviews for this arnica cream and decided to give it a try. Well, I have been using it for the past week and the bruise is disappearing before my eyes! It is almost gone. I am dumbfounded. What magic is in this?
