What Are Star Ratings?
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Traditional Use (May Not Be Supported by Scientific Studies)
Marshmallow (not to be confused with confectionery marshmallows) has long been used by herbalists to treat coughs and sore throats .1 Due to its high mucilage content, this plant is soothing to inflamed mucous membranes. Marshmallow is also used by herbalists to soothe chapped skin, chilblains (sores caused by exposure to cold), and minor wounds.
How It Works
How It Works
Mucilage, made up of large carbohydrate (sugar) molecules, is thought to be the active constituent in marshmallow. This smooth, slippery substance is believed to soothe and protect irritated mucous membranes. Marshmallow has primarily been used as a traditional herbal soothing agent for conditions of the respiratory and digestive tracts.14
How to Use It
The German Commission E monograph suggests 1 1/4 teaspoon (6 grams) of the root per day.15 Marshmallow can be made into a hot or cold water tea. Often 2–3 teaspoons (10–15 grams) of the root and/or leaves are used per cup (250 ml) of water. Generally, a full day’s amount is steeped overnight when making a cold water tea, 6–9 teaspoons (30–45 grams) per three cups (750 ml) of water, or for fifteen to twenty minutes in hot water. Drink three to five cups (750–1250 ml) a day. Since the plant is so gooey, it does not combine well with other plants. Nevertheless, it can be found in some herbal cough syrups. Herbal extracts in capsules and tablets providing 5–6 grams of marshmallow per day can also be used, or it may be taken as a tincture—1–3 teaspoons (5–15 ml) three times daily.
