What are essential oils used for?
Over hundreds of years, essential oils have been shown to treat a broad range of medical conditions including anxiety/stress, sleep, migraines, nausea, sinus congestion, even help with boosting immune system response.
One study found that those who breathed a mixture of ginger, spearmint, peppermint, and cardamom had significantly reduced nausea after surgery. Other research shows that lavender oil can lower levels of the stress hormone cortisol, resulting in reduced stress. It has been shown that inhaling lemongrass aroma before a stressful event can prevent anxiety.
