Reading other reviews have been way more helpful than what I'm about to write, it almost seems pointless to do it!
I have always used this for sinus issues. Recently, I made my bestie sit over a bowl of boiling water with a couple of drops in it with a towel over her head. 5 minutes and she already felt better. Placing that in a steaming hot bathroom while showering was also good.
It really makes such a difference to your breathing and clearing your airways out. This smelt so good that I just placed some in another bowl in our living room so that the air felt so much cleaner and yummier!
I really think this is something every home should have in the cupboard.
Absolutely want to try this in the vacuum cleaner thought, @chikoboo, going to try that asap!
I now carry a bottle around with me in my handbag ALWAYS. I bought it because I was going away for the weekend & forgot my pimple cream & I could feel Mt Vesuvius building itself on my chin. It totally kept the monstrosity away. I also used it on a mozzie bite, which I usually scratch until it bleeds. I was amazed that the itch was gone so quickly. I've read other reviews and am going to try many of them out. It's potent stuff!
