Aromatherapy is the practice of using natural plant oils for improving the physical well-being of a person. These aroma-producing oils come from flowers, leaves, stalks, rind, and roots. Aromatherapy is an alternative medicine that considers your sense of smell’s influence over your thoughts, emotions, moods, memories, behavior and physiological functions.
The versatility of aromatherapy is immense. For this article, we will be discussing some of the therapeutic uses of oils for common complaints. There are oils that treat more than one problem including lavender and peppermint. Several scientific studies have been cited to support how these essential oils offer means for emotional and physical healing and rebalancing moods.
1. Essential Oils for Pain:
Lavender, chamomile, clary sage, juniper, eucalyptus, rosemary, peppermint, lavender, and green apple
Lavender oil is one of the most popular essential oils that are commonly used to relieve headaches and neck pain. Its analgesic and anti-inflammatory effects were confirmed by a study  published in the August 2015 issue of Brazilian medical journal Anais da Academia Brasileira de Ciencias. Another study  supports the effectiveness of lavender oil in treating pain when combined with conventional treatments such as acupressure.
2. Essential Oils For Insomnia:
Lavender, chamomile, jasmine, benzoin, neroli, rose, sandalwood oil, sweet marjoram, ylang-ylang, lemon
A Korean study  combined lavender, roman chamomile, and neroli oils to assess its effect on anxiety, sleep, and blood pressure of coronary artery disease patients. It found out the value of this blend as an independent nursing intervention for improving the sleep quality of these patients. In another study,  the oils of ylang-ylang, lavender, neroli, and marjoram were effective in improving the sleep quality of middle-aged women with hypertension.
3. Essential Oils For Stress:
Lavender, lemon, bergamot, jojoba, clary sage, peppermint, vetiver, pine, ylang-ylang, chamomile
4. Essential Oils For Anxiety:
Lavender, bergamot, rose, clary sage, lemon, Roman chamomile, orange, sandalwood, rose-scented geranium, ylang-ylang, and pine
One study  mixed lavender and bergamot oils to evaluate the blended oil’s aroma-therapeutic effects in treating anxiety. The study confirmed the relaxing effect of the synergistic blend and its potential use in medicine for curing depression or anxiety in humans. In 2006, a study published in Phytotherapy Research  provided evidence for the usage of ylang-ylang oil as a therapy for depression.
5. Essential Oils For Nausea And Vomiting:
Mint, ginger, lemon, orange, ginger, dill, fennel, chamomile, clary sage, lemon, and lavender
Yavari and colleagues  conducted research in 2014 to determine the effect of lemon inhalation aromatherapy on nausea and vomiting of pregnant women. Results showed the positive effect of lemon scent in reducing nausea and vomiting during pregnancy. In another study,  a blend of essential oils of ginger, spearmint, peppermint, and cardamom was proven to be another effective aromatherapy treatment for postoperative nausea.
6. Essential Oils For Memory And Attention:
Sage, peppermint, rosemary, lemon, and cinnamon
The effect of peppermint on memory performance has been widely explored. The International Journal of Neuroscience published a study  in 2008 that offered evidence for the impact of peppermint on increasing alertness of healthy participants. In 2009, another study  posited the potential of aromatherapy for improving the cognitive function of patients with Alzheimer’s disease. The study used rosemary and lemon essential oils.
7. Essential Oils For Low Energy:
Black pepper, peppermint, cardamom, cinnamon, clove, angelica, jasmine, tea tree, rosemary, sage, and citrus
In 2013, an experiment  was conducted to explore the effectiveness of peppermint essential oil on exercise performance. The stimulating effect of peppermint was attributed to its analgesic, anti-inflammatory, and antioxidantproperties.
8. Essential Oils For Fatigue Exhaustion And Burnout:
Basil, bergamot, clary sage, jasmine, lemon, peppermint, rosemary, ginger, cypress, sandalwood, grapefruit, and grapefruit
Inhaling a mixture of essential oils  including peppermint, basil, and helichrysum was found to be effective in reducing the perceived level of mental fatigue or burnout. This study first appeared in The Journal of Alternative and Complementary Medicine.
How To Use The Essential Oils?
As mentioned above, the most common ways to use essential oils are aromatically, topically, internally, and externally. You can diffuse the oils into the air, inhale them directly, use as perfume or cologne, or as a natural room deodorizer. Essential oils are applied topically through massage, hot or cold compress, or bathwater. Certain oils may be used in cooking or as supplements, but they should typically NOT be taken internally unless accepted as a food-grade substance, and even then in minute quantities.
Around the home, essential oils have also found applications in sprays, carpet deodorizers, insect repellent, and household cleaners.
