Marsh Mallow

Althaea officinalis

Marsh Mallow is a perennial herb originally from Africa. The plant is now commonly found in a wide variety of urban environments.

Marsh Mallow can reach more than 1 metre in height during the vegetative period. The short-stalked leaves are broad with three or five lobes and toothed along the leaf margin. Marsh Mallow has white flowers, with pale purple lines along the petals, similar to the common Mallow.

The stem, and in particular the root systems, emit mucilaginous substance when they are cut. The plant is historically known for its medicinal properties and used to treat the irritation of mucous membranes.

Traditional uses
  • It is often used to treat bronchitis1 and sore throat2
  • Decoction of the Marsh Mallow roots is traditionally used for pharyngitis3
  • The leaves are used for urinary tract infections4
  • The root of Marsh Mallow contains soluble fibre that in water creates mucilage (gel) with emollient properties. This helps to soothe the throat and reduces the body’s urge to cough2 and it is highly effective in soothing and calming irritations to the skin due to its moisturising qualities2
  • Antitussive properties (in vivo evidence)4,8
  • Anti-inflammatory properties (in vivo evidence)5
  • Anti-microbial properties9 (in vitro evidence)
