A friend of mine got a vail of something with rosemarry in it, the girl that gave it to him told him that he could use it on his hair. But it gave him an alergic reaction. It smelled like rosemarry but I could smell other things in it too.. it made his skin swell but only for a small amount of time. some of it got on me and it did the same thing so I know it wasn't just cause of him... she swears she only used natural things in it so my question is what els could she have put in it?
