These two:
Lime and Vetiver combined with some fractionated coconut oil in a roller bottle is working a little.
An even amount of drops of each oil in a small roll on bottle are mixed together and applied to the back of the neck. It is a bit of a strong smell and some find it unpleasant so I add a drop of lavender to the back of the neck as well.
The question you are asking is....is it working?
Well yes and no. It is helping a little but he still needs his meds. But you never know everyone is different so this combo may work for you or your child so give it a shot.
