What Is Aromatherapy and What Are Its Benefits?

Scents can have an intense impact on our mood. They can trigger a range of feelings and memories. Some fragrances are energizing, others are calming.

Aromatherapy is a form of holistic therapy that works through sense of smell and through the skin. Aromatherapy practitioners use natural plant extracts, usually in the form of essential oils, to promote physical health and emotional well-being.

Holistic medicine takes a whole person approach—mind, body, and spirit. Aromatherapy has been used in holistic healing for thousands of years.

Ancient Wisdom for Modern Times

The term aromatherapy was first used by René-Maurice Gattefossé, a French perfumer and chemist who saw the healing potential of lavender for treating burns.1

He may have coined the term, but people around the world have been using some variation of aromatherapy for ages. Ancient cultures in China, India, and Egypt incorporated aromatic plant oils into resins, balms, and salves to treat various ailments and improve health.2 They understood through experience and passed-down knowledge that certain plants and their extracts were useful for treating a range of ailments, from respiratory infections to menstrual cramps.

Today science is uncovering why. A variety of essential oils, including lemongrass and thyme, are known to have antimicrobial, antiviral, antifungal, and insecticidal properties.3

In aromatherapy, essential oils are inhaled or applied to the skin using diffusers, spritzers, body oils, lotions and creams, massage oils, inhalers, clay masks, and facial compresses. The oils are also sometimes added to haircare products, liquid soap, toothpaste, mouthwash, and bathwater.

Aromatherapy Benefits

Aromatherapy is a complementary therapy, meaning it’s used alongside—but sometimes instead of—conventional medicine. It’s increasingly being recognized by the scientific and mainstream medical communities for its physical and mental health benefits.4 Aromatherapy can help:

  • Lift mood
  • Reduce stress and anxiety
  • Relieve pain
  • Improve sleep quality
  • Soothe achy joints
  • Fight bacteria, viruses, and fungi
  • Aid digestion
  • Treat headaches and migraines
  • Boost immunity
  • Aid menstrual problems
  • Soothe psoriasis

Some of the most popular aromatherapy oils are sage, eucalyptus, lemongrass, patchouli, lavender, ginger, peppermint, rosemary, and ylang ylang.

Using Aromatherapy Oils

Essential oils can be safely used either through inhalation or topically.

  • Inhalation: You can use a diffuser to evaporate essential oils into the air. You can also mix essential oils with water for use in a spritzer bottle or drop oils into bathwater. Aromatherapy oils not only stimulate the olfactory system, they can also act as a decongestant (e.g., peppermint and eucalyptus oils) and a respiratory disinfectant. As the scent molecules make their way from the nose and mouth to the brain, they affect the limbic system, which is tied to emotions, stress, memory, heart rate, blood pressure, and other bodily functions—it’s through this pathway that aromatherapy improves mood and sense of well-being.
  • Topical application: To use essential oils for massage, dilute them in a carrier oil (like sweet almond oil or coconut oil) or incorporate them into lotions and creams. When massaged into the skin essential oils may help improve circulation. 

Essential oils are generally safe, but some side effects are possible, including allergic reactions, skin irritation, rashes, nausea, and headaches. Never apply concentrated essential oils directly to skin—make sure they’re properly diluted in a carrier oil.
