No we aren’t talking about the fluffy white things you add to hot chocolate, though that is a modern adaptation of what was once a traditionally prepared food.

We’re talking about the Marshmallow plant Athaea officianlis. Marhsmallow is one of our go-to plants for all manner of health concerns, mainly for it’s ability to help bring moisture into the body and soothe irritated tissues.

These two properties together make this plant a powerhouse in the medicinal herb world.

There are a wide variety of scenarios where you may want something soothing and moistening. A dry irritated cough, a dry and sore throat, dehydration, dry skin, irritated digestive tract, red and itchy eyes, you think of it, marshmallow is probably a sure bet.

Most of the medicinal plants we work with are drying in nature, not all of them, but most of them. Make a list of all the drying plants and then one of all the moistening plants and the list will be heavily weighted in favor of the dry. Because of this, us herbalists tend to use the moistening plants heavily to help balance out our formulas, and for scenarios where you need to add moisture to a body system (like those mentioned above).

Marshmallow is the premier moisture plant. Add it to a glass of cool water and you’ll see the mucilaginous compound turn the water thick. These compounds hold the water and help deliver it to the places in the body where it’s needed (this works best when applied to the affected tissues directly).

It’s also rather neutral in taste, which means it’s very easy to add to blends or any other tea you may be drinking to help combat dryness and soothe tissues.

However, the bland taste and mucilaginous compounds make it not the most pleasant to drink on its own, so we prefer to add something tasty along with it, be it spearmint or hibiscus or anything else you like the flavor of, just to help the medicine go down.

DESCRIPTION & GROWING

Herbal Academy

A perennial that can reach up to 7 feet in height, marshmallow has thick, downy-soft, shortly-petioled, ovate-cordate leaves, with toothed margins that are 2 – 3 inches in length, and 1.25 inches in width. The root is white and the flowers are generally a pale pink.

It is a perennial herb that is native throughout damp areas of Europe and western Asia. Marshmallow is naturalized in North America in salt marshes from Massachusetts to Virginia and is now cultivated from Western Europe to Russia

The long, yellow roots are tapered, long, and thick with tough exteriors. The entire plant is filled with mucilage. The plant resembles hollyhock (Althaea rosea). Its genus name, Althaea, comes from the Greek word altho, which means “to cure.”

Its order name, Malvaceae, is derived from the Greek word ‘malake’, meaning soft. The modern common name comes from the Anglo-Saxon word ‘merscmealwe’, in which mersc means “marsh” and mealwe translates to “mallow.”

PART(S) USED & HARVESTING

  • Both marshmallow leaf and root are used in commercial preparations. Herbal formulations are made from either the dried root or leaf (unpeeled or peeled). (2)
  • The mucilage content of the root, leaves, and flowers is highest in the late fall and winter (approximately 11%) and lowest in the spring and summer (5-6%) (2)
  • Pharmacopeia-grade marshmallow must have an “index swelling” of no less than 12 and pass botanical identification by macroscopic and microscopic authentication. The British Pharmacopoeia requires marshmallow leaf to be harvested before the flowering period and pass identification by thin-layer chromatography, and confirmation with additional qualitative standards, including water-soluble extraction of not less than 15% (2)
  • Harvest the roots in the fall. Plant should have at least 2.5 to 3 years of growth before roots are ready. Leaves can be harvested throughout the summer while soft, fresh, and free of discoloration or mildew.

PREPARATION & DOSING

  • Tea: can be added to other herbs for moisture in any tea formula. By itself, is best as a cold-water extraction let to sit overnight
  • Tincture:  must be made a glycerite tincture as the active constituents (the mucilage) are water-soluble and do not extract well into alcohol. The Modern Herbal Dispensary has great instructions on how to do this.

ENERGETICS

  • Slightly sweet
  • Moistening, neutral in temperature

HERBAL ACTIONS

  • Antitussive
  • Demulcent
  • Emollient
  • Mucilaginous
  • Pre-biotic

USES

Internally:

    • respiratory tract mucous membrane inflammation
    • dry cough
    • inflammation of the gastric mucosa
    • diarrhea
    • peptic ulcers
    • constipation
    • urinary tract inflammation
    • any situation where additional moisture is needed

Topically:

    • abscesses
    • varicose and thrombotic ulcers
    • a poultice for skin inflammation or burns, and for other wounds.
  • According to animal research, mucilaginous herbs like marshmallow root inhibited coughing by forming a protective coating on the mucosal lining of the respiratory tract, shielding it from irritants (3153062030).
  • Marshmallow reduced the transport velocity of isolated ciliary epithelia and may protect mucous layers in the hypopharynx and exert spasmolytic, antisecretory, and bactericidal properties (31530). The antitussive activity has been demonstrated by oral doses of marshmallow root extract and a marshmallow polysaccharide (100mg/kg and 50mg/kg respectively) in cats compared to a non-narcotic cough suppressant.
  • A polysaccharide dose of 50mg/kg was equally effective as “Syrupus Althaeae” in a dose of 1,000mg/kg (62021). In animal research, the extract was less effective than marshmallow polysaccharide (62029). The demulcent properties of marshmallow may be due to the reduction of the local irritation that causes gastritis
  • Combinations of marshmallow preparations with steroids have been used in the management of dermatological conditions, and the plant appears to possess anti-inflammatory activity that potentiates the effect of topical steroids (6202562024).
  • In vitro, the anti-inflammatory effects of an ointment containing marshmallow extract and dexamethasone (0.05%) were superior to those of the individual ingredients in the alleviation of chemically induced rabbit ear irritation (62026).
  • Hypoglycemic effects: At doses of 10mg/kg, 30mg/kg, and 100mg/kg, marshmallow reduced plasma glucose levels to 74%, 81%, and 65% of prior values, respectively, after seven hours in rats (62022).
  • Marshmallow mucilage is not altered in the digestive tract until it reaches the colon, where it may be partially or completely digested via bacterial action (62029).

HISTORICAL USES

  • Marshmallow has been used in traditional European medicine for more than 2,000 years, and its therapeutic use was first recorded in the ninth Century. It was widely used in Greek medicine and later its use spread to Arabian medicine. The Emperor Charlemagne ordered marshmallow cultivation in monasteries (2)
  • Marshmallow root and extract were formerly official entries in the U.S. Pharmacopeia and the National Formulary (2)

CAUTIONS FOR USE

  • Marshmallow root has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912). …when used orally in medicinal amounts (412).
  • The mucilaginous compounds can interfere with absorption of some medications in the digestive tract, so it’s a good idea to let people know this and to advise them to take their medications away from the tea
  • ANTIDIABETES DRUGS = Moderate Be cautious with this combination. Animal research suggests that marshmallow can have hypoglycemic effects (62022). Theoretically, marshmallow might have additive effects with hypoglycemic therapy (4). Monitor blood glucose levels closely. Dose adjustments to antidiabetes drugs may be necessary. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
  • LITHIUM  Moderate Marshmallow is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
  • ORAL DRUGS Moderate The mucilage in marshmallow might impair absorption of oral drugs (1111219)
  • HERBS AND SUPPLEMENTS WITH HYPOGLYCEMIC POTENTIAL: Animal research suggests that marshmallow may have hypoglycemic effects (62022). Theoretically, marshmallow might have additive effects when used with other herbs and supplements with hypoglycemic potential. This might increase the risk of hypoglycemia in some patients. Some herbs and supplements with hypoglycemic potential include alpha-lipoic acid, bitter melon, chromium, devil’s claw, fenugreek, garlic, guar gum, horse chestnut, Panax ginseng, psyllium, Siberian ginseng, and others

CONSTITUENTS

  • Key Constituents – mucilage, starch, pectin, flavonoids, phenolic acids, sucrose, asparagine, tannins Leaf: flavonoids, scopoletin, polyphenols (Hoffman, 2003).
  • Marshmallow root preparations consist of peeled or unpeeled dried root of Althaea officinalis L. and contain mucilage polysaccharides (6.2-11.6%) composed of galacturonorhamnans, arabinans, glucaris, and arabinogalactans; carbohydrates (25-35%); flavonoids; glycosides; sugars (10% sucrose); amines (up to 12% asparagines); fat (1.7%); calcium oxalate; coumarins; phenolic acid (62031); and sterols.
  • Purified homogenous mucilage of marshmallow is composed of L-rhamnose, D-galactose, galacturonic acid, and D-glucuronic acid in molar ratio of 3:2:3:3 (62022). Scopoletin, quercetin, kaempferol, chlorogenic acid, caffeic acid, and p-coumaric acid are also present in the roots.
  • Marshmallow is high in aluminum, iron, magnesium, selenium, tin, and substantial amounts of calcium. It is also high in pectin, which may lower blood glucose concentrations. The root contains 25-35% of the mucilage; however, the content of purified mucilage is much lower.
  • Asparagine, sugar, pectin, and tannin have also been identified in the root.
  • Xylose, glucan, arabinogalactan, and acidic polysaccharide containing 2-O-alpha-D-galacturonopyranosyl-l-rhamnose (62032) are also present in the hydrolysate of leaf and flower mucilage.
  • Extracts from hybrid plants have been found to be more mucilaginous, with a different sugar composition compared to native plants (62023).

SPIRITUAL/MAGICAL USES

  • Marshmallow has been used as part of rituals to treat impotence, and as an aphrodisiac. Seeds collected under a full moon are made into an oil and used on the genitals. An amulet made of leaf and root has been kept under the genitals and used for the same purpose. Marshmallow has been used in rituals for the dead and has been planted over grave sites. (2)
