You know those menthol ointments right? Its very popular in Malaysia as a pain reliever. It works in many ways. It contains methly salicylate which relieves pain by absorbing into the skin.
It also work as a counter irritant. It irritates the area so either the new irritant takes your mind off the current pain or that it increases the immune system activity to that area.
Its a type of aroma therapy because most of these ointment uses some sort of strongly scented oil such as mint, and cajaput oil makes it great to release nausea.
It comes in a balm or oil. Some newer ones comes in creams too. Why am I writing this? I have a headache and I need to use one and get some stuff of my chest.
