Overview and Health Benefits
When hearing the term “marshmallow”,’ many might think of the sweet treat, but the actual marshmallow plant (Althaea officinalis) has been known for its soothing properties long before it became a candy ingredient. Althaea officinalis has a long history of use in herbal medicine, revered for its soothing and healing properties (McIntyre, 2014). The plant, with its velvety leaves and broad flower petals, is rich in mucilage, a soft, slippery substance released when the root is steeped in water. Both the root and the leaf are used for their therapeutic benefits. Traditionally, marshmallow has been used to treat a variety of ailments, particularly those involving inflammation and irritation of mucous membranes. Modern scientific research supports many of these traditional uses, confirming its effectiveness in alleviating conditions of the respiratory, digestive, and urinary systems.
Key Benefits
- Soothes Mucous Membranes: Marshmallow root and leaf contain high levels of mucilage, which form a protective layer on mucous membranes, reducing irritation and inflammation (Deters et al., 2010).
- Anti-inflammatory: The plant has demonstrated significant anti-inflammatory effects, making it useful in treating conditions like gastritis and sore throat (Deters et al., 2010; Zaghlool et al., 2019).
- Respiratory Support: Marshmallow is effective in relieving coughs and soothing bronchial irritation, often used in herbal syrups and teas for respiratory ailments (Shah et al., 2011; Nosál'ova et al., 1992).
- Digestive Aid: It can alleviate gastrointestinal discomfort, such as heartburn and stomach ulcers, by forming a protective barrier over the stomach lining (Zaghlool et al., 2019).
- Urinary Health: Marshmallow's demulcent properties support urinary tract health, soothing inflammation and irritation commonly associated with infections (Ahmed et al., 2023).
Safety
Marshmallow is generally regarded as safe, with minimal side effects reported (McIntyre, 2014). However, it can potentially lower blood sugar levels in certain individuals; the high mucilage content might also interfere with the absorption of prescription medications and supplements, so it is recommended to take marshmallow at least six hours before or after other drugs (McIntyre, 2014).
As with any herbal remedy, it is prudent to consult with a qualified medical herbalist before incorporating marshmallow into your regimen if you have pre-existing medical conditions or are taking prescription medications.
