Safety, Uses, and Benefits of Thyme Oil

Thyme is an aromatic herb that has been used in Mediterranean cuisine and traditional herbal medicine practices for millennia. 

In addition to its antifungal, antibacterial, and anti-inflammatory properties, thyme is linked to several health benefits, including blood pressure-lowering effects and its potential to promote healthy skin. 

Discover five incredible benefits of thyme oil and learn how to use this aromatic essential oil safely.

What is thyme oil?

Thymus vulgaris, widely known as thyme, has been used for millennia to season foods and prepare herbal teas and medicinal ointments.

The thyme plant belongs to the Lamiaceae family, along with other herbs, including lavender, oregano, rosemary, sage, and basil. It’s a shrubby herb with long, woody stalks covered in small, grayish-green leaves that can be used fresh, dried, or distilled into essential oils. 

Thyme oil is a concentrated essential oil derived from the aerial parts of thyme, including the leaves and flowers. It has a strong, spicy, and warming aroma and a bold herbaceous flavor. 

Thyme oil is composed of about 50 percent thymol, a monoterpenoid phenol known for its powerful antiseptic, analgesic, and antioxidant properties.

Because of its unique chemical composition, thymol is often used commercially in cosmetics, mouthwashes, toothpaste, hand sanitizer, and creams, where it serves as a natural preservative and antimicrobial agent.

5 benefits of thyme oil 

Thyme oil’s impressive health benefits are mainly attributed to its thymol content, which contributes to its potent antimicrobial, anti-inflammatory, and antioxidant properties.

Here are five incredible benefits of thyme oil.

1. Antifungal properties

Fungal overgrowth, often caused by yeast species such as Candida albicans, can cause various symptoms, including oral thrush, brain fog, skin rashes, itching, and vaginal yeast infections. 

Due to its high concentration of antimicrobial thymol, thyme oil has been shown to be an effective remedy for controlling fungal overgrowth.

“Thyme herb oil is very powerful against candida infections,” explains Dr. Berg. “It’s an antifungal agent that can help manage fungus and yeast overgrowth without harming the friendly microbes on the skin or in the gut microbiome.” 

Thyme's antifungal properties may also help improve conditions such as tinea versicolor, which causes white patches on the skin due to an overgrowth of Malassezia yeast.

2. Helps suppress coughs

Thyme has antitussive and expectorant effects, which can help manage coughs and thin mucus in the sinuses and airways. These effects are attributed to its volatile oils, particularly thymol and carvacrol.

A study published in Arzneimittelforschung found that a combination of thyme and ivy leaf extract reduced coughing fits by nearly 70 percent in patients with acute bronchitis after one week. 

In addition, thymol’s antimicrobial properties may help reduce the risk of bacterial infections, further supporting respiratory health and promoting quicker recovery from respiratory illnesses.

3. Promotes healthy skin

Thyme’s anti-inflammatory and antimicrobial effects may help protect against acne-causing bacteria and reduce skin irritation associated with conditions such as eczema. 

Thyme oil may also be more effective at eliminating harmful bacteria on the skin’s surface than antibiotic creams in the long term. 

Unlike topical antibiotics, which can lead to the development of resistant bacterial strains and disrupt the delicate balance of the skin's microbiome, thyme effectively targets harmful bacteria without destroying beneficial microbes.

4. Supports healthy blood pressure

Hypertension, widely known as high blood pressure, is a risk factor for several cardiovascular diseases, including heart attacks, strokes, and atrial fibrillation.

Thyme, along with rosemary, oregano, and clove, are some of the best sources of polyphenols. These antioxidant compounds may reduce the risk of high blood pressure by improving arterial function, enhancing blood vessel flexibility, and reducing inflammation.

Though more research is needed in humans, a study published in Oxidative Medicine and Cellular Longevity found that “...wild thyme (a spice plant, rich in polyphenolic compounds) induced a significant decrease of blood pressure and vascular resistance in hypertensive rats.”

5. Enhances dental health 

The overgrowth of harmful bacteria in the mouth can cause cavities, bad breath, and gum disease, significantly increasing the risk of tooth decay and tooth loss.

Due to its natural antibacterial activity, thymol is often used in dental products, including toothpaste and mouthwashes. 

A study published in the Alexandria Engineering Journal found that regular use of thyme oil could inhibit oral bacterial overgrowth, prevent tartar buildup, and reduce biofilms. These actions support better oral health and may help reduce the risk of cavities and gum disease.

How to use thyme oil

Thyme oil can be used topically, internally, or aromatically to support overall health. 

To use thyme topically, dilute up to four drops of essential oil in one tablespoon of olive or coconut oil and massage into the skin. 

It’s recommended to do a skin patch test before applying thyme oil to larger areas to avoid adverse effects. 

Thyme oil can be used internally by diluting one to two drops in half a cup (four ounces) of water. This allows its beneficial properties to support digestive health, boost the immune system, and provide antimicrobial effects.

Dried or fresh thyme can also be used to season meat, roasted vegetables, soups, beverages, and sauces. 

For those following a low-carb diet, thyme is one of the many keto-approved foods ideal for spicing up your favorite dishes.

Additionally, adding three to four drops of thyme oil in a diffuser can relieve stress, and inhaling steam or mist infused with thyme oil may help clear congestion and soothe an irritated throat.

Remember that concentrations of thyme oil can vary across different products, and it’s essential to carefully follow the product instructions.  

It’s also recommended to consult your healthcare provider before incorporating essential oils into your routine to ensure safe usage and determine the best approach for your specific health needs.

Safety and side effects

While thyme oil is generally well-tolerated by most healthy adults, it’s important to understand that it can cause skin irritation or allergic reactions in sensitive individuals. 

Thyme oil isn’t recommended for individuals taking antihypertensive medications as this can cause dangerously low pressure when ingested in excess.

Thyme oil is also contraindicated in pregnant women, as it may increase the risk of miscarriage and fetal developmental complications. 

It’s believed that excessive consumption of thyme may mimic estrogen, potentially disrupting pregnancy hormones. However, thyme used in culinary amounts is generally considered safe for pregnant and breastfeeding mothers.

Individuals allergic to oregano, sage, or lavender essential oils should avoid thyme due to a heightened risk of side effects. Conducting a skin patch test can help identify any sensitivity to thyme before broader application.

Additionally, Thymus vulgaris essential oil is highly concentrated and may cause skin irritation if applied directly. To prevent redness and burning, always dilute a few drops in a carrier oil, such as coconut or olive oil, before application.

Key takeaways

Thyme is a perennial herb used worldwide for culinary purposes and as an effective home remedy for various ailments. 

Linked to its antimicrobial and antioxidant effects, potential benefits of thyme oil include a reduced risk of fungal overgrowth and acne, enhanced dental health, and better blood pressure control.

Thyme oil can be applied topically, taken internally, or used in aromatherapy. However, to minimize the risk of side effects, it’s crucial to dilute the essential oil properly and consult your healthcare provider before use.
