Aromatherapy is a term that is used to describe a variety of treatments that involve essential oils. Essential oils are extracts from plants and they are believed to have many benefits, including reducing stress and improving mood. There are some risks associated with aromatherapy, however. For example, certain essential oils can be toxic if ingested in large quantities. Additionally, if essential oils are applied directly to the skin in high concentrations, it can lead to skin irritation. It's important to consult a healthcare professional before starting any aromatherapy treatment to ensure that you're aware of any potential risks and how to safely use essential oils.
