Overview: Myrrh is the gummy-like resin (sap) of certain trees that grow in Africa and the Middle East. It is used as aromatherapy and added to soap, cosmetics, perfume, and incense for its pleasant fragrance. Dietary supplements that contain myrrh are used for many reasons, but their benefits are not well defined. Taking myrrh by mouth may cause an upset stomach. Applying it to the skin may cause an allergic skin reaction in some people. Before using myrrh, tell your health care provider about any health conditions you have or medicines you are taking.

Uses

What is myrrh used for?

Myrrh is used for various reasons, but its benefits are not well defined. Some common reasons for using myrrh include the following.

  • Indigestion (dyspepsia)
  • For certain infections or infestations
  • To improve oral health
  • To reduce inflammation from various causes

Note: Myrrh is generally recognized as safe (GRAS) by the FDA for use as a food flavoring. Learn more about GRAS status here. The FDA has not reviewed myrrh dietary supplements or essential oils for safety and effectiveness. Learn more about dietary supplements here. Learn more about essential oils here.

How does myrrh work (mechanism of action)?

Myrrh is the gummy-like resin (sap) of commiphora trees. Most myrrh products are made from Commiphora myrrha, which is known as African myrrh, or C. madagascariensis, which is known as Arabian myrrh. Its distinctive and pleasant smell has led to its use in cosmetics, soaps, perfumes, and incense and as aromatherapy. Myrrh is also commonly used as a food flavoring and a dietary supplement.

Myrrh contains many substances, some of which may be able to reduce swelling (inflammation). It is sometimes used as a mouthwash or liquid extract to help improve the health of the mouth and gums. It is also used as a dietary supplement to help with stomach problems and inflammation in different parts of the body. But there is very little research on the use of myrrh for any reason, and its benefits are not well defined.

Some of the chemicals in myrrh may also be able to kill bacteria, parasites, and worms when studied in a lab. But these chemicals must be present in high concentrations, and taking myrrh by mouth is not expected to provide enough of these chemicals to kill any organisms. In fact, some research has shown that myrrh is not helpful in people with serious worm infections, such as schistosomiasis. If you are concerned that you have or are at risk for an infection from a parasite or worm, speak with a health care provider right away.

Natural substances, such as myrrh, contain many chemicals. The amounts of each chemical in a specific myrrh product may vary. Some, none, or all of these chemicals may have effects on the body. These effects may change depending on how much of each chemical is found in the product you are using.

How should I store myrrh?

You should store myrrh according to the product label. Most dietary supplements should be kept in a cool, dry location that is out of the reach of children and pets and not in direct sunlight.

What should I know about myrrh before using it?

Myrrh is commonly used as a fragrance in soap, cosmetics, perfume, and incense. It is also added to foods as a flavoring and is available as an essential oil and dietary supplement. These products cannot be marketed to treat or cure a disease.

Read and follow the directions on the specific product you are using, or use it as recommended by your health care provider.

Keep myrrh out of the reach of children.

Herbal products, such as myrrh, naturally contain many chemicals. The amount of each chemical in a specific myrrh product can change for many reasons, including the area where the tree grew, the weather during growth, the time of year when the resin was harvested, and the way that it was processed after it was harvested. If you switch to a new bottle or a different brand, you may not have the same effects or side effects because of this variability. Talk to your health care provider if you have questions or concerns.

Myrrh is available in many forms, including a solid resin, essential oil, liquid extract, and capsule. Each of these forms may contain different amounts of the chemicals that are naturally found in the resin.

If you are using a liquid product, use an accurate measuring device to measure your dose. A household spoon is not an accurate measuring device and may cause you to take the wrong dose. Ask your pharmacist what measuring device to use.

The FDA has not tested myrrh products to confirm that they contain the ingredients stated on their labels. Some dietary supplements have been tested by third-party organizations to confirm that they contain the ingredients listed on their labels and do not contain any harmful chemicals.
