My wife got interested at essential oils. She always explore and searching for the uses and benefits of different essential oils. Essential oils are natural because it is extracted from plants. I am happy because she is happy for what she is doing. We have two diffuser at home the whale diffuser and koala diffuser. It was so cute. My son always looking at them because it is attractive. Essential oils are good but we are always taking extra precautions because over using it are sometimes dangerous.
