Lavender oil is a special oil that is made from a purple flower called lavender. It smells really nice and is often used in things like soap, lotion, and candles.
When you use lavender oil, it can help to make you feel calm and relaxed. It can even help you to sleep better at night if you put a little bit on your pillow.
To make lavender oil, people take the flowering tops of the lavender plant and then steam or press them to get the oil out. Then, they put it in a bottle for you to use at home. It's important to remember that you should never drink lavender oil, or put it in your eyes or ears, because it can be dangerous.
Overall, lavender oil is a nice-smelling oil that can help you feel happy, calm, and ready for bed.
