Herbal Uses of Marshmallow Root

Marshmallow root is a mostly perennial herb found worldwide and native to Europe, Western Asia, and Northern Africa. Marshmallow root’s latin name and botanical classification is Althaea officinalis L. (A. officinalis) from the Malvaceae family. It has been used for centuries as an herbal remedy. The most-studied benefits of marshmallow root have been in treating respiratory and digestive tract symptoms and in skin health and wound repair. 

In this article, you will learn more about the benefits of marshmallow root, the products available, and its side effects and drug interactions. 

7 Marshmallow Root Benefits

The following are the benefits of marshmallow roots:

Treating Digestive Ulcers 

One in vitro and in vivo (animal) study from 2019 demonstrates that marshmallow root has protective properties for treating gastrointestinal (mouth, throat, and stomach) ulcers. Researchers determined that the benefits of marshmallow root for digestive issues are derived from its components, including vitamins and antioxidants, which prevent cell damage, and plant compounds like tannins, which promote a healthy mucosal lining within the digestive tract.

However, more studies are needed to determine the effectiveness in humans.

Supporting Skin and Hair Health 

The antioxidant and protective properties of marshmallow root support healthy cell functioning, which promotes healthy skin and hair. For this reason, marshmallow root is sometimes used as an ingredient in natural shampoos and conditioners.

Treating Skin Conditions and Wound Healing

Marshmallow root can be used for wound healing. It can reduce skin irritation and inflammation associated with wounds or conditions like contact dermatitis or eczema.

One 2023 review on therapeutic herbs for wound healing found that marshmallow root has immune-system enhancing and antibacterial properties that can kill gram-positive bacteria (characterized by the color the bacterial turn when staining in the lab) and speed healing.

Aiding in Metabolism 

Marshmallow root affects hormones. One animal study from 2014 found marshmallow root extract impacted thyroid-stimulating hormone (TSH) and may aid in metabolism (the body process that changes what you eat and drink into energy).

Treating Cough and Sore Throat 

Marshmallow root is used in herbal remedies to relieve coughs and throat pain. Researchers say the effects of marshmallow root's medicinal extracts are immediate and offer a protective, antioxidant-rich film that coats inflamed mucosa (the inner lining of the nose, throat, and lungs), soothes irritation, and helps relieve coughs. This film protects the respiratory tract, promoting faster symptom relief and healing.

Reducing Water Retention

The anti-inflammatory and diuretic (rids the body of water and sodium) properties in marshmallow root reduce water retention (edema).

Treating Sore or Cracked Skin and Reducing Pain Associated With Breastfeeding 

Marshmallow root contains the following beneficial plant compounds:

• L-rhamnose
• D-galactose
• D-galacturonic acid
• D-glucuronic acid

These plant compounds treat sore and cracked nipples during breastfeeding. No data exist on whether marshmallow root can be excreted into breast milk or what the safety and efficacy of marshmallow root is in nursing mothers or infants.

Marshmallow root is available in several forms. You can purchase marshmallow root online, at natural food stores, and in products sold in grocery stores.

You can find commercial marshmallow root tea in single-serving tea sachets (a small, scented cloth filled with herbs). Follow the steeping directions, which usually are to pour boiling water over the tea bag and let steep for five to 10 minutes.

Taking Marshmallow Root Extract 

Directions can vary for every capsule, tincture, or extract. Also, some products contain just marshmallow root, while others are a blend of marshmallow root and other herbal ingredients.

Using Marshmallow Root Creams for Skin Conditions 

One study found 1% marshmallow root ointment was effective in treating skin irritation in children. The ointment was applied topically (to the skin) twice a day for a week and then three times per week for three weeks.

Side Effects and Drug Interactions From Marshmallow Root

Marshmallow root is generally considered safe for use and is well tolerated in adults, with rare reports of allergic reactions. However, it can interact with certain drugs. For instance, it should not be used when taking lithium and diabetes drugs or when taking drugs that act as diuretics, such as blood pressure medication.
