Overview

Marshmallow root is one of the classic soothing herbs in Western herbalism, traditionally valued for its ability to calm irritation, moisturize dry tissues, and protect inflamed mucous membranes. It is most commonly used for dryness, irritation, heat, and inflammation affecting the digestive, respiratory, and urinary systems.

Unlike strongly stimulating or antimicrobial herbs, marshmallow works primarily through its rich mucilage content, which creates a soothing, protective coating over irritated tissues. It is especially useful in dry, irritated conditions where tissues feel inflamed, raw, or depleted.

Marshmallow root is considered one of the gentlest herbs in herbal medicine and is widely used for children, sensitive individuals, and long-term soothing support.

Basic Uses

Marshmallow root is commonly used for:

• Dry or irritated coughs
• Sore throat and throat irritation
• Acid irritation and digestive inflammation

• General soothing support during recovery from irritation or inflammation
