Tea tree oul should be a must in all bathroom cupboards. I use it for a variety of things like cold sore. I usually put a wee bit on and this helps it dry up and is usually gone fast. Pimples, treatment cleaning for after piercings. You would need to dilute it if you intend to use to clean a peircing though. I use on my daughters as a traeatment for head lice, dilute into a spray bottle and spray everyday before school, this helps to stop the nits attaching.
So many uses its the best!!
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!
Tips: A little goes a long way - this stuff is pure and therefore smells STRONG!
