What Is Eucalyptus Essential Oil?

Eucalyptus essential oil is obtained from fresh leaves of the tall, evergreen eucalyptus tree (Eucalyptus globulus). The essential oil is colorless and has a distinctive taste and odor. The potent medicinal benefits of eucalyptus oil are due to a compound called [1] eucalyptol (also known as cineole), which has antimicrobial properties. The oil is used in a variety of over-the-counter drugs including rubs, inhalers, liniments, rash creams, and mouthwashes.

Eucalyptus is native to Australia and has spread in the past few centuries to other parts of the world including India, Europe, and South Africa. It is also known as fever tree, Tasmanian blue gum tree or stringy bark tree, depending on where it is located in the world. Though many countries produce eucalyptus oil in small quantities, the prime source of eucalyptus oil for the world is still Australia.

The numerous health benefits of eucalyptus oil have attracted the attention of the entire world, and it has stimulated a great deal of exploration into its usage in aromatherapy as well as in conventional medicine.

Health Benefits Of Eucalyptus Oil

Let’s take a look at the most popular health benefits and uses of eucalyptus oil in detail.

1.Treats Colds & Flu

Eucalyptus essential oil is effective for [2] treating a number of respiratory tract infections including cold, cough, running nose, sore throat, nasal congestion, bronchitis, and sinusitis. According to a research study, it has the ability to inhibit bacteria such as S. pneumonia, H. influenza, and parainfluenza that cause sinus infections, fever, and flu. Eucalyptus oil is an expectorant and helps decongest sinuses.

To treat colds, you can add a few drops of the oil to hot water and inhale the steam, or add it to your diffuser. Alternatively, rub a little oil on the pillow to ensure a good night’s sleep if you are troubled with congestion and wet cough.

2.Hair Lice Treatment

Due to its well-known qualities as an insect repellent and natural pesticide [3], eucalyptus oil is frequently used as a natural treatment for lice. Apply a few drops of the oil mixed with carrier oils on lice-infested hair to get rid of lice.

Note: Eucalyptus essential oil is usually not recommended for children below the age of 5; it’s best to consult a doctor before use.

3.Hair Care

Eucalyptus essential oil has potent antiseptic and anti-fungal properties which help remove the build-up of germs in hair follicles. This helps prevent conditions like dandruff, itchy scalp, and psoriasis.

For best results, you can blend a few drops of the herbal oil with a tablespoon of coconut or olive oil to moisturize and heal the scalp. Also, the oil acts as a stimulant and increases blood flow, when a few drops are directly applied to the scalp. This also helps boost hair growth.

4.Treats Asthma

The anti-inflammatory properties of [4] cineole in eucalyptus essential oil help relieve asthmatic symptoms. Simply massage 1-3 drops of the oil onto the chest and the soothing effect of the aroma and vapors will calm the throat and dilate the blood vessels, which will allow more oxygen into the lungs and thus, help restore normal breathing.

5.Heals Wounds

When eucalyptus essential oil is exposed to air, an ozone layer is formed that makes the oil a potent antiseptic. Therefore, it is used to [5] heal wounds, ulcers, burns, cuts, abrasions, and cold sores. It is also an effective salve for insect bites and stings. Furthermore, it protects the open wound or irritated area from developing infections due to microbial activity and exposure to air.

6.Removes Mental Exhaustion

Eucalyptus oil, a stimulant, helps remove exhaustion and mental sluggishness and rejuvenates people who are feeling under the weather or are sick. It can also be effective in treating stress and mental disorders as inhaling its vapor help increase blood circulation to the brain.

7.Improves Brain Function

Eucalyptus essential oil is commonly used to stimulate mental activity and alertness. Since the essential oil is considered [7] a vasodilator, it increases the blood flow by relaxing the blood vessels and allowing more blood to circulate. Basically, more blood to the brain means more brain power.

Eucalyptus essential oil is commonly employed in classrooms as a form of causal aromatherapy to increase student performances.

8.Relieves Muscle Pain

The volatile eucalyptus oil is analgesic and anti-inflammatory in nature. If you are experiencing muscle pain or soreness, massaging oil on affected areas in a circular motion helps relieve stress and pain.

9.Treats Joint Pain

Eucalyptus oil is often recommended for patients suffering from rheumatism, lumbago, sprained ligaments and tendons, stiff muscles, aches, fibrosis, and even nerve pain. It is a stimulant and helps increase blood circulation, providing pain relief. A research study showed that inhaling its vapor reduced pain, swelling, and inflammation in patients who underwent total knee replacement surgery.

10.Dental Care

Eucalyptus essential oil is very effective against cavities, dental plaque, gingivitis, bad breath (halitosis), and other dental infections owing to its germicidal. This is why it is so commonly found [8] as an active ingredient in mouthwash, toothpaste, and other dental hygiene products.

11.Removes Intestinal Germs

Eucalyptus oil is a vermifuge and is frequently used to remove intestinal germs [9]. Studies have shown that ingesting eucalyptus oil can deter many of the bacterial, microbial, and parasitic conditions that arise in the various parts of the body, particularly in susceptible areas like the colon and intestine.

12.Manages Diabetes

When ingested, eucalyptus oil can help control blood sugar because it contains powerful flavonoids (quercetin, kaempferol), phenolics (tannins, ellagic acid), and terpenoids (cineole, alpha-pinene). These potent compounds help reduce [10] post-prandial hyperglycemia and treat type 2 diabetes. Diabetics can also benefit by frequently massaging eucalyptus oil to the skin topically, or inhaling it as a vapor.

13.Treats Fever

Eucalyptus oil is also used [11] for treating fever, and is often referred to as “fever oil”. You can add a few drops of the herbal oil to a warm water compress and place it on the forehead frequently to reduce body temperature during high fever.

A research study by NYU detailed [12]the therapeutic use of eucalyptus oil in curing sinus infections, headaches, and allergies.

15.Treats Tuberculosis & Pneumonia

Eucalyptus essential oil has antibacterial and antiseptic qualities which help treat chronic obstructive pulmonary disease (COPD), pneumonia, and tuberculosis.

When massaged onto the chest and used as a vapor rub or inhalant, it can relieve the signs and symptoms of harmful conditions like tuberculosis by clearing the lungs and reducing inflammation. It is best if applied to both, the chest and the back.

16.Immune system

Eucalyptus oil, rich in cineole, is one of the best oils to strengthen the immune system. Apart from its ability to keep colds and flu at bay, it can be used to treat hay fever (seasonal allergy), acne, and endometriosis.

17.Skin Care & Cleanser

Eucalyptus oil is often applied topically to treat skin infections as its main compound, cineole, has antibacterial properties. The oil helps speed up healing and treat acne, eczema, sun spots, blemishes, aging, and pimples. Furthermore, it can be combined with olive or coconut oil to form a natural sunscreen and moisturizer.

18.Treats Fungal Infections
