The medicinal plant that calms coughs, relieves colds, and improves digestion

The marshmallow plant, scientifically known as Althaea officinalis, has been recognized for its medicinal benefits since ancient times. Native to regions spanning Europe, Western Asia, and North Africa, this herbaceous plant, which can grow up to a meter and a half tall, is cultivated for its therapeutic properties.

Its root is particularly rich in beneficial compounds, including mucilage, pectin, and flavonoids. Mucilage, which constitutes between five and 20% of the plant, is a key component responsible for its medicinal effects. According to Pablo López Schimpf, a specialist in Nutrition and Applied Clinical Phytotherapy, these compounds primarily found in the root, but also in the leaves, coat mucous membranes, offering protection and reducing irritation.

The mucilages present in marshmallow coat the mucosa, especially the oropharyngeal, protecting it from local inflammations, reducing irritation and cough, and promoting rehydration.

Traditionally, marshmallow has been employed to alleviate symptoms of the common cold and cough. López Schimpf explains that the mucilage forms a protective layer, particularly on the oropharyngeal mucosa, thereby reducing irritation and suppressing coughs. Scientific evidence backs this traditional use, with controlled clinical studies demonstrating the effectiveness of marshmallow root extract as an antitussive in adults and showing a reduction in cough severity and frequency in children.

Beyond respiratory relief, marshmallow is also considered an ally for gastrointestinal health. It is recognized for its role in the symptomatic treatment of mild dyspeptic or gastrointestinal disorders, including bloating and flatulence. Scientific organizations like ESCOP and the European Medicines Agency (EMA) have approved its use for such conditions. Additionally, preliminary research suggests potential anti-inflammatory effects, with some studies indicating its utility in topical applications for skin conditions like eczema and furunculosis, although further investigation is needed in this area.
