“Essential oils speak to our memories, our heart, and our emotions.” – Maren Good


AromatherapyThe term aromatherapy means “treatment using scents.” Aromatherapy is a form of herbal medicine since it utilizes plants (such as flowers, spices, or herbs) for medicinal purposes. However, whereas in traditional herbal medicine whole herbs are typically ingested, in aromatherapy only the volatile, essential oils of plants are used for their healing benefits. These essential oils are very concentrated and should not be ingested. Instead they confer their healing properties through the power of scent. When we inhale the vapors from an essential oil, the scent goes directly to our brain via the limbic system. There that scent can evoke memories, induce feelings of calm, impact alertness, and otherwise positively impact overall well-being.

In addition, essential oils are readily absorbed through the skin, which enables them to promote a variety of healing effects within the body. When utilized in massage or in skin care products, essential oils can act as pain relievers, anti-inflammatories, fungicides, diuretics, expectorants, and antibacterials.

Tips for Using Essential Oils

  • Many essential oils can cause burns or irritation, and most must be diluted with carrier oils (such as jojoba, almond, grapeseed, coconut, or sunflower oil) before using on the skin.
  • Lavender and tea tree oil are two of the few oils that don’t require dilution. They are ideal for treating cuts & scrapes as they are antibacterial and antifungal.
  • Many essential oils should not be used during pregnancy.
  • Hydrosols come from the condensed water left following essential oil extraction, which makes them more dilute and gentle.
  • Peppermint hydrosol is cooling for hot flashes. Neroli hydrosol is uplifting and acts as an antidepressant.
  • Citrus oils should ideally be organic. Citrus and needle oils are good for a year, and then they oxidize. However, you can still use them in a diffusor.
  • Essential oils are excellent for respiratory health. Eucalyptus, rosemary, pine, ravensara, niaouli, myrtle, tea tree and spruce are all helpful for that purpose.
  • It can take 5000 roses to make just 1 tsp of essential oil, making high quality rose oil very expensive.
