We always have a bottle of Thursday Plantation tea tree oil in the cupboard, the bottle also travels with us.
Main use for us is on a damp cotton wool ball to clean face, or dab on spots, for the whole family.
It does have a strong aroma, which I quite like.
I am sure this tea tree oil can be used for a majority of other ailments, luckily we haven't experienced.
I use this on spots (great for drying out!) and on mosquito bites and it stops the scratching pretty quickly. It's so small you can take it anywhere and smells great.
Tips: I also use it as a preventative measure for nits. I put 6 drops in a water sprayer and my girls spray their hair with it everyday before brushing. Both have long hair and (touch wood) neither have had nits :)
