"Essential oils come from Mother Nature, they can’t harm you."
We see this type of assumption a lot.
When we tell a customer to be sure to skin test an oil before using it topically, or to be extremely careful around small children; they sometimes seem surprised!
Just because a product is natural, does not mean it isn't strong.
On the contrary, essential oils are very strong, and can absolutely be used in careless and unsafe ways that could harm you!
Consult with a professional if you are ever unsure about how to safely use a specific essential oil; every essential oil is different.
