Marshmallow (Althaea officinalis) is a soft, nurturing plant known for its ability to bring comfort to dry, irritated tissues, both inside and out. Traditionally used for its cooling and moistening properties, marshmallow is considered a demulcent herb, meaning it supports and coats mucous membranes and delicate surfaces.
Whether brewed as tea or used externally, marshmallow is a gentle ally when the body needs a little extra soothing.
Herbalists have long used marshmallow to:
Support a calm, comfortable digestive tract
Soothe the throat and lungs during dry, irritated times
Promote urinary tract comfort
Ease dryness or discomfort in the mouth and GI tract
Gently support the skin when applied topically
The plant’s high mucilage content gives it a naturally cooling, protective quality.
Marshmallow has been used in herbal traditions throughout Europe and the Middle East for thousands of years. Both the leaves and roots were valued for their ability to soothe internal and external tissues.
In traditional herbalism, the leaf was commonly prepared as a tea or cold infusion to moisten and comfort the respiratory and digestive systems. Marshmallow was also added to poultices and washes to calm and soften the skin.
Known as one of the gentlest herbs, marshmallow is often chosen when tissues feel hot, dry, or irritated.
Marshmallow is a tall, flowering perennial that thrives in moist, rich soil. It has soft, velvety leaves and pale pink flowers that resemble hollyhock, its botanical cousin.
While the root contains the highest concentration of mucilage, the leaves also carry this beneficial substance, making them useful for soothing infusions and topical applications.
Marshmallow leaf can be used in a variety of comforting ways:
Cold infusions – to retain its soothing mucilage
Herbal teas – often blended with mint, chamomile, or licorice
Skin washes or compresses – for gentle topical use
Sitz baths or soaks – for calming support
Soothing steams – combined with other gentle herbs
Its mild, slightly sweet taste makes it easy to enjoy alone or in combination with other herbs. Marshmallow root is also used and is sometimes preferred for stronger tease or decoctions.
Marshmallow is generally well tolerated. Because of its coating nature, it may slow the absorption of medications when taken at the same time. To be safe, it’s best to take herbs and medications at least 1–2 hours apart. As always, consult a qualified practitioner if pregnant, nursing, or managing a health concern.
