The Popularity of Thieves Oil
One of the most well-recognized essential oil blends for supporting immune and respiratory health is the thieves oil blend. This ancient mixture has been around for centuries and has a very intriguing background. According to Medicine Net:
Folklore has several variations about the origin of thieves oil. One of the stories says that it was used by four thieves in the 15th century to rob people during the bubonic plague. The thieves applied a mixture of several herbs, spices, and essential oils on their clothes and bodies that would allow them to rob ailing people without catching the illness. Because it was believed to be first used by thieves, the mixture of essential oils got the name “thieves oil.”
Thieves oil is a blend of several essential oils. The most commonly used constituents in thieves oil are cinnamon, eucalyptus, clove, lemon, and rosemary. The oil has a rich and spicy aroma and is thus used in various household and personal care products. You can also make thieves oil at home….

Some of My Favorite Uses for the Thieves Oil Blend
Thieves essential oil blend has multiple properties that support our overall resiliency, lung health, and our defense and repair system. I tend to use it whenever I feel run-down, have been around crowds, have been exposed to someone who has been sick, and/or for rejuvenating vitality during the change of seasons. It is one of my most preferred oil blends to diffuse to cleanse the air.
The Thieves oil blend I use is one of the more common mixtures of clove, rosemary, cinnamon, eucalyptus, and lemon oils. This combination contains various compounds that can remove impurities in the air (including mold) and provide antioxidant support (R, R). These oils are also antimicrobial, can benefit lung health (e.g., eucalyptus is high in 1-8 cineole), and aid microbiome balance.
Below is a summary of some of the characteristics of these essential oils contained in the popular version of the thieves oil blend.
The Most Common Essential Oils in the Thieves Blend and Their Properties
Cinnamon (Cinnamomum verum) bark essential oil is a favorite spice oil with a sweet and powerful scent. It has antimicrobial, antifungal, antioxidant, and antidiabetic properties (due to its cinnamaldehyde).
Lemon (Citrus limon) oil is a familiar citrus oil, which are all noteworthy for their limonene content. Limonene has been shown to support cellular health, enhance immune function, ease digestion, and much more. Citrus smells also have mood and nervous system supporting properties. These scents are uplifting and can ease the mind and enhance focus when diffused.
Clove (Syzygium aromaticum) bud oil has been noted to be antimicrobial, antioxidant, and insecticidal. The main compound is eugenol, which is at least 50% of its makeup. This constituent has anti-inflammatory, pain-relieving (analgesic, anesthetic, antinociceptive), and antitumoral properties.
Rosemary (Rosmarinus officinalis) leaf essential oil is most well-known for how it aids brain health and cognitive performance. It is stimulating to the nervous system (chemotype 1-8 cineole). Rosemary oil has been shown in clinical trials to enhance energy and memory. Additionally, it has antimicrobial properties and has been studied for stimulating hair growth.
Eucalyptus Radiata (Eucalyptus radiata) essential oil is one of the approximately 20 species of 900 eucalyptus oils that has been marketed for its naturally occurring constituent eucalyptol, or 1-8 cineole. As a result, this oil can defend against germs and support lung health.
Some Applications of Thieves Essential Oil
Due to the combination of cinnamon, lemon, clove, rosemary, and eucalyptus oils present in the thieves oil blend, it can be used for a variety of wellness objectives. These include:
- modulation of the immune system and inflammation
- aiding digestion
- antioxidant protection
- inhibiting unwanted microbe growth
- blood sugar balance
- mood upliftment
- memory enhancement
This blend can also be diffused to decrease environmental triggers. For example, a recent study found that aromatic release of the thieves blend decreased pollen counts. It has also been shown to lower mold counts. As a result, the thieves blend makes a great companion when camping or traveling where mold and allergen exposure may occur.
Additionally, due to its stimulating and memory-enhancing properties, diffusing thieves oil at home or at work can help with improving concentration. Students may also enjoy its focus-inducing aroma when doing homework.
Topically, thieves blend must be diluted due to the potent oils it contains. When properly applied, it can aid in alleviating discomfort in the body and mouth. For oral care, a small dab on a toothpick, or a diluted drop of a quality thieves oil in natural toothpaste, can be used acutely in the mouth to the area that needs attention. I like to proactively apply a drop to the bottoms of my feet whenever I head out to public places with lots of germs.
