This stuff is incredible! I've always been a bit iffy on panadol and reluctant to take it unless I absolutely have to do things that require me to be a little more chipper than a bear woken midwinter. This stuff actually works. Granted it's not going to cure a full on migraine, but for your normal run of the mill headache this is definitely my go-to (alongside a giant glass of water).
I apply it to my temples and to the pressure points on the back of my neck beneath the hairline about half an inch either side of centre (google to reflexology points for headache for precise locations of this and others that you can use the product on). I think a part of why it works is just taking the time to refocus and have a little self massage session, but hey if it works it works.
The smell is incredible, gorgeous Lavender and Peppermint. Sometimes I find just sniffing the balm can stave off a headache when it's threatening to come on.
The one possible drawback I can think of is that it is greasy and thick and it may muss with your makeup when applied to the temples. Small price to pay though really.
Speaking of price, I think it's priced really modestly and a little goes a long way.
Headache or not I like the smell . It does help. I get migraines and this really helps ;) I'm not sure how but I'm.not bothered. If it works it works!!
