What is Marshmallow Root & What Is It Used For?

The marshmallow plant is a popular, natural ingredient for soaps, teas, and infusions. While it’s not quite the same as the fluffy white desert topping, marshmallow plants, known botanically as Althaea officinalis, have a long history of use in wellness and DIY herbal traditions.

But what is marshmallow root? And why are so many people curious about it? Let's take a quick but in-depth look at its origins, uses, and its unique place in the world of handmade products.

What Is Marshmallow Root?

Marshmallow root comes from the perennial herb Althaea officinalis, also known as the marshmallow plant. It grows in damp, marshy environments and has been used in various traditional practices for centuries.

The entire plant, roots, leaves, and flowers, has been used historically, but it’s the mallow root that contains a thick, mucilage-like substance often used to create teas, balms, or herbal infusions. Marshmallow root is typically dried and ground into powder, or steeped in hot water for infusions.

What Is Marshmallow Root Used For?

Most commonly, marshmallow root is included in homemade teas, herbal oils, or cosmetic infusions. It’s reported to help coat and soothe surfaces, which is why it's often found in products aimed at supporting comfort for dry skin or the throat area.

The roots of marshmallow plants are used for many things. The most common applications include:

  • Herbal teas and infusions (like marshmallow root tea)
  • Topical salves or skin balms
  • Hair rinses or scalp serums
  • Oil infusions for soap or lotion bases

It's also occasionally added to DIY bath soaks or pillow sprays, though its effectiveness in these applications varies depending on concentration and method of preparation.

Marshmallow Root Benefits (Reported)

Though modern research is still evolving, marshmallow root benefits have been reported in traditional herbalism, often relating to:

  • Soothing the throat – Many people brew marshmallow root tea when dealing with dryness or mild irritation.
  • Supporting the skin – Believed to calm stressed or dry skin when used in balms or oil infusions.
  • Aiding digestion – In historical practices, marshmallow root was used as a gentle support for gut comfort and regularity.

Keep in mind: these are reported uses based on traditional applications, and not all benefits are supported by clinical research. Always check with a qualified practitioner before using marshmallow root in health-related products.

Is Marshmallow Root the Same as a Marshmallow?

Nope! The sweet, squishy marshmallows we toast by the fire were originally made using extracts from the marshmallow root plant, but modern marshmallows are entirely sugar-based. So while the name is a nod to the herb’s history, today’s dessert marshmallows no longer contain any plant-derived ingredients.
