Great, until it wasn't

I wanted to love this so much, and I did for a few weeks. When I first started using it, I noticed it didn't do enough to stop the odour on days when I was very active but I was willing to keep using it for the benefits of being natural. After about 3 weeks, I started to react really badly to it - my under arms became very itchy and when i applied this deodorant it would actually burn! I didn't use it for a few days and tried it again but the same thing happened, so unfortunately I had to give it up.
