Wonderfully fresh, but otherwise found no effect

I had bought this balm for an aching knee to rub. The scent is delightfully fresh and it feels pleasantly cool and not greasy. A curative effect / analgesic effect but it has not shown me a long time, despite the regular use, therefore: Yes, I like it, but no, due to a lack healing power, I would not buy it again. However, yes that's not say whether other people not yet the devil's claw has a healing effect. My advice, therefore, to try it.
