From cooling your body in summer to treating sunburns, and restraining insects, the eucalyptus oil benefits are phenomenal. The uplifting fragrance of the eucalyptus essential oil makes it irresistible to use.

So, let’s understand about this oil in detail here.

What Is Eucalyptus Oil?

Eucalyptus essential oil is extracted from the leaves and twigs of Eucalyptus Radiata through the process of steam distillation. The eucalyptus tree belongs to the Myrtaceae family and grows to a height of 100 feet.

It has rough black bark at the lower half, a smooth bark at the top, thin leaves, and numerous flowers. The tree is usually found growing along the banks of rivers, creeks, and mountain regions (1).

The principal places of production of eucalyptus essential oil include Australia, Russia, South Africa, and Tasmania.

Scientific Name Of Eucalyptus Oil

The botanical name of eucalyptus is Eucalyptus radiate.

Fact: Eucalyptus Radiata has more oil glands in its leaves than other species. 

History Of Eucalyptus Oil

Described as the most appropriate eucalyptus oil for aromatherapy, the essential oil obtained from Eucalyptus radiate has been used for centuries. It is native to Australia and was the world’s first commercially-used Eucalyptus species.

The tree is also called as Fourth river peppermint. Eucalyptus radiata exudes a type of white gum and hence, the name “river white gum.”

The term Eucalyptus came from the Greek language, where “eu” means “well” and “kalypto” means “I cover.”

Therefore, eucalyptus generally refers to the cap that covers the buds of the flowers until the buds mature. Once the buds are mature, they force the cap to open.

There is also an interesting study claiming that the aroma of eucalyptus essential oil helps to control the craving for chocolates.

Uses of eucalyptus oil

Health Benefits Of Eucalyptus Oil

Though the eucalyptus oil benefits are enormous, the most prominent ones include:

1. Soothes bronchitis symptoms

Inflammation in the lining of bronchial tubes – the ones that carry air to & from your lungs is termed as bronchitis. It may be acute or chronic. The causes vary from viral or bacterial infection to smoking tobacco and air pollution.

The symptoms differ in each stage. Wheezing, persistent cough, headache, and fever are the most common symptoms during the acute phase. In the chronic stage, bronchi inflame, swell and become narrow. There is an overproduction of mucus in case of bronchitis.

However, the monoterpenes present in the eucalyptus essential oil help to decongest the mucus formed and further, relieves the symptoms of acute bronchitis (4, 5).

Just inhaling the aroma of eucalyptus essential oil during the night would help a lot. You can dilute the oil and rub it around your rib cage. You can also rub it all over the front torso.

Rest is crucial at this time. Always try to keep yourself warm and avoid smoke.

All types of eucalyptus oil can be used to treat bronchitis. You can also make a blend using 1 drop each of eucalyptus oil, thyme oil, ginger oil, frankincense oil, and ravensara oil. Take this mixture and dilute it with a carrier oil before using it on the skin (6).

2. Combats candida infection

You have been introduced to Candida when you were born. It resides in a healthy human being, and it is significant too. However, when it overgrows, it is called an infection.

The severity depends on the region it grows. Initially, it is not a big issue, but when left untreated, it may be fatal.

The candida infection always has an underlying cause. It usually includes diseases that compromise the human immune system. Studies have found that the topical application of eucalyptus & peppermint oil had significant inhibition of the Candida species (7).

All you have to do is blend 10 drops of peppermint oil with 5 drops of eucalyptus oil. Take 4 drops from the mixture and dilute it using 2 tablespoons of coconut oil. Apply the infected region twice a day and massage it in a clockwise motion. Always keep that area away from moisture.

3. Remedy for sinus infection

All of us have 14 to 16 sinus cavities filled with mucus. However, the little mucus helps filter the air we breathe and prevents us from infections. Inflammation in the sinus is called sinusitis.

Inflammation causes excessive mucus secretion. It, in turn, leads to sinus congestion. Sinusitis causes cough, nausea, sore throat, headache, and diarrhea.

However, the antibacterial, anti-inflammatory, and decongestive properties of eucalyptus essential oil help relieve this problem (8, 9, 10).

You can use eucalyptus oil in two ways to relieve sinus congestion:

  • Steam inhalation
  • Massage

Steam Inhalation: Blend 2 drops of eucalyptus oil with 3 drops of rosemary oil and 1 drop of peppermint oil. Take 3 drops of the combination and add it in a bowl of boiling water.

Inhale the steam through the nose. KEEP THE EYES TIGHTLY CLOSED DURING STEAM INHALATION.

Massage: Blend 5 drops of rosemary oil with 2 drops of geranium oil, 5 drops of eucalyptus oil, and 1 drop of peppermint oil. Take 3 to 5 drops of the mixture and dilute it with 2 tablespoons of suitable carrier oil.

Massage around the neck, front, and back of the ears, cheekbone, nose, and forehead. Be cautious about the eye region.

Just inhaling its aroma or a gentle massage helps the body to relax and sleep better so that your energy is reserved. It relieves any pain in the body and makes you feel energized.

Your nail tells a lot about your health. Traditional medical systems in India and China always had the practice to look at your hair and nails to figure out what is wrong with your body.

The analysis includes seeing whether the nail is fragile, deformed, flat, too soft, or too hard. Doctors also examine the color of the nail.

Fungal nail infection is also common, and it begins like a white or yellow spot. It is treatable but can come back. It causes nail deformation and thickening. (19)

Eucalyptus essential oil helps you to maintain healthy nails and treat general nail infections. Blend 10 drops of tea tree oil and 5 drops of Eucalyptus oil. Take 3 or 4 drops from the mix and dilute it in 2 tablespoons of coconut oil. Massage the nail bed and regions around the nail 3 times a day for better results.
