Marshmallow Powder Uses

Marshmallow powder is a versatile ingredient with many uses.

Marshmallow Powder Uses

It comes from the root of the marshmallow plant, which has been used medicinally for over 2,000 years.

What is Marshmallow Powder?

Marshmallow powder is made by drying and grinding the root of the marshmallow plant, scientifically known as Althaea officinalis. The marshmallow plant is part of the mallow family and is native to Europe, Western Asia, and Northern Africa.

Marshmallow root contains a gummy substance called mucilage made up of polysaccharides. When mixed with water, mucilage becomes slippery and sticky, which is why marshmallow preparations are known to have demulcent (soothing) properties.

How is Marshmallow Powder Made?

Marshmallow powder is made by carefully processing the marshmallow plant root. Here is an overview of the key steps:

  • The marshmallow root is harvested after 2-3 years of growth when the mucilage content is highest. This is typically in early fall.
  • The roots are washed, chopped, and dried either outdoors, using the sun and air, or indoors at low temperatures.
  • Once fully dried, the roots are ground into a fine powder.
  • The marshmallow root powder is then packaged and stored in air-tight containers away from heat, air, and moisture to preserve freshness.

Key Takeaway: Marshmallow root powder is made by harvesting, chopping, drying, and grinding the marshmallow plant root. This preserves the valued mucilage content.
