Which thyme essential oil?

Did you know it’s not possible to buy plain “thyme” oil? That’s because the thyme plant can produce different variations of its thyme oil. These are called essential oil chemotypes.

Two thyme plants can have the exact same genus and species—Thymus vulgaris—yet produce dramatically different thyme essential oils. (Nature is amazing!)

What is thyme?

First, lets talk about what thyme is. Then we will get into how to best use some of the most popular variations of thyme oil.

Thyme is an aromatic herb, a member of the mint family, that is widely used in aromatherapy due to its strong and invigorating aroma. Thyme oil is extracted from the plant and is known for its antibacterial and antiseptic properties.

Thyme has been used for centuries in aromatherapy and traditional medicine due to its antimicrobial and aromatic properties. The ancient Egyptians and ancient Greeks used thyme in their baths, incense, and as a natural remedy for various ailments, including respiratory issues, digestive system problems, and wounds.

Today it is often used in aromatherapy to help alleviate respiratory issues, such as congestion and coughing. Thyme oil is also believed to have therapeutic benefits for the mind and body, with some studies suggesting that it may help improve mood, boost mental clarity, and reduce stress levels. Thyme oil can be used in a variety of ways, including in diffusers, inhalers, massage oils, and bath salts. Its herbaceous and slightly spicy scent is a popular choice for those seeking a natural and effective way to promote overall wellness and relaxation.

Thyme oil can be affected by chemotypes, which refer to the different chemical compositions of the thyme oil depending on the species and variety of the thyme plant. Chemotypes can result in variations in the aroma, potency, and therapeutic properties of thyme oil, which can affect its effectiveness in aromatherapy and other benefits. It is important to choose the correct chemotype of thyme oil based on its intended use to ensure optimal results.

What are essential oil chemotypes?

Have you ever seen the letters “ct” on your essential oil label and wondered what it means?

These two little letters have a dramatic impact on your blends!

When a plant produces variations in its essential oil—as thyme does—the letters “ct” tell you which chemical type of the oil you have, also known as its “chemotype.”

Factors such as moisture, temperature, the region the plants grow in, and the amount of sunlight they get all affect the chemical composition of oil that thyme produces. Each type contains a different cocktail of natural chemical components. These components are the molecules that literally make up thyme oil. You can think of them as the oil’s “ingredients.”

How do we know what components are present in an essential oil? A GC/MS test tells us!

GC/MS stands for “Gas Chromatography/Mass Spectrometry.” It’s a laboratory test. You can think of it like purity testing. Not only does a GC/MS test verify an oil’s purity, it also identifies the individual components present in the oil.

When we look at the list of components for a bottle of thyme essential oil, we can see which are more prevalent. This tells us which chemotype of thyme oil is in the bottle.

Thymus vulgaris actually produces six common chemotypes: oils rich in thymol, linalool, carvacrol, geraniol, a-terpineol, and thuyanol.

In this post, we’ll explore two of the most popular of thyme essential oil: thymol and linalool

Thymol is a super-strong, potent component. It has powerful actions (especially against germs), but can irritate skin and mucous membranes.

Linalool is an ultra-gentle component. It can relax the mind, calm stress, and soothe your entire system holistically.

Understanding these two chief constituents of this medicinal herb will allow you to take advantage of its health benefits.

While both chemotypes of thyme are useful for reducing germs (and fungi) and for boosting immunity, thyme ct thymol essential oil is more appropriate for acute, short-term use.

The component thymol can be harsh on skin and mucous membranes. Use thyme ct thymol essential oil sparingly in topical blends and inhalers. We suggest a 1% dilution (5 to 6 drops of essential oil per 1 oz/30 ml of carrier oil such as jojoba oil). The thymol content adds a robust kick to short-term blends for issues like strengthening immunity during cold season, or soothing itchy feet.

If you don’t have an acute, urgent need for thyme ct thymol’s strength, you can use it in plenty of blends where its potent touch won’t irritate sensitive skin or noses.

Try it in blends for natural cleaning, diffuser blends to purify your indoor air, and mists to support your breath.

Use thyme ct thymol oil to:

  • Clean your home with natural antibacterial properties
  • Purify indoor air of unpleasant odors
  • Massage achy muscles & joints
  • Boost your immune system
  • Open your respiratory system
