Aromatherapy inhalers are a great way to experience the benefits of aromatic blends on the go. They are reusable. The tubes are metal with a glass vial that holds a cotton wick that can be replaced once the oils dry up. Typically, each inhaler can last for several months. Aromatherapy is the perfect way to support your emotions, stress, and sleep. I have developed this products and recipes over the years to assist with stress, emotional imbalances, focus issues, lulls in energy, sadness, and sleep issues.
