Thymus vulgaris is an herb long used for medicinal purposes. More commonly known as thyme, it's thought to contain compounds with antioxidant and antibacterial effects. Available in dietary supplement form, Thymus vulgaris is used to treat a wide range of health problems.

One of the constituents of Thymus vulgaris is thymol, a compound shown to possess anti-inflammatory, antioxidant, and antimicrobial properties. (An antimicrobial is a substance that destroys or suppresses the growth of microorganisms, including bacteria and fungi.)

Health Benefits of Thymus Vulgaris

Preliminary research suggests that Thymus vulgaris may offer a number of health benefits. For instance, animal-based studies published over the past decade indicate that Thymus vulgaris may act as a pain-reliever, protect the brain from aging-related damage, and shield both the brain and liver from the harmful effects of alcohol abuse.

In recent tests on human cells, scientists have determined that Thymus vulgaris may also curb inflammation and boost immune function.

Additionally, a study published in the Journal of the American Mosquito Control Association in 2005 found that compounds extracted from the essential oil of Thymus vulgaris may act as a mosquito repellent.

While few studies have tested the health effects of Thymus vulgaris in humans, there's some evidence that the herb may help alleviate menstrual pain. In a study published in the Journal of Research in Medical Sciences in 2012, researchers assigned 120 female college students with menstrual cramps to treatment with either Thymus vulgaris supplements or Ibuprofen. Results revealed that both treatments were similarly beneficial in relieving pain.

Uses for Thymus Vulgaris

Thymus vulgaris is touted as a natural treatment for the following health conditions:

Thymus vulgaris is also purported to stimulate the immune system, enhance liver health, and reduce pain.

When applied to the scalp, the essential oil of Thymus vulgaris is said to promote hair growth and aid in treatment of alopecia areata.

In addition, Thymus vulgaris is thought to prevent cavities. It's also sometimes used in mouthwashes to fight bad breath.

Is Thymus Vulgaris Safe?

Since so few studies have tested the effects of Thymus vulgaris supplementation, the safety of long-term use of this herb is unknown. However, Thymus vulgaris has been found to cause several side effects, including stomach upset.

In addition, there's some concern that Thymus vulgaris may inhibit blood clotting. Therefore, it's crucial to avoid use of Thymus vulgaris at least two weeks prior to undergoing surgery.

Alternatives to Thymus Vulgaris

Several other herbs may help enhance immune function and shield you from illness. For example, taking herbs like andrographis, astragalus, echinacea, and elderberry at the first sign of a cold may help treat symptoms and shorten the cold's duration.

For herbal pain relief, alternatives to Thymus vulgaris include white willow bark, devil's claw, and ginger. Studies show that each of these herbs may have pain-reducing effects.

You can also manage chronic pain with certain mind-body techniques.
