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:

Used for Why
1 Star
Refer to label instructions
Elecampane has been used traditionally to treat coughs associated with asthma.

Traditionally, herbs that have a soothing action on bronchioles are also used for asthma. These include marshmallow, mullein, hyssop, and licorice. Elecampane has been used traditionally to treat coughs associated with asthma.

Elecampane is a soothing herb that has been used to treat coughs associated with bronchitis, asthma, and whooping cough.

Elecampane is a demulcent (soothing herb) that has been used to treat coughs associated with bronchitis, asthma, and whooping cough. Although there have been no modern clinical studies with this herb, its use for these indications is based on its high content of soothing mucilage in the forms of inulin and alantalactone. However, the German Commission E monograph for elecampane does not approve the herb for bronchitis.

Chronic Obstructive Pulmonary Disease

Elecampane is used traditionally to promote mucus discharge.

Mullein is classified in the herbal literature as both an expectorant, to promote the discharge of mucus, and a demulcent, to soothe and protect mucous membranes. Historically, mullein has been used as a remedy for the respiratory tract, particularly in cases of irritating coughs with bronchial congestion. Other herbs commonly used as expectorants in traditional medicine include elecampane, lobelia, yerba santa (Eriodictyon californicum), wild cherry bark, gumweed (Grindelia robusta), anise(Pimpinella anisum), and eucalyptus. Animal studies have suggested that some of these herbs increase discharge of mucus. However, none have been studied for efficacy in humans.

Elecampane has a long history of use for relieving coughs.

The mucilage of slippery elm gives it a soothing effect for coughs. Usnea also contains mucilage, which may be helpful in easing irritating coughs. There is a long tradition of using wild cherry syrups to treat coughs. Other traditional remedies to relieve coughs include bloodroot, catnip, comfrey (the above-ground parts, not the root), horehound, elecampane, mullein, lobelia, hyssop, licorice, mallow, (Malvia sylvestris), red clover, ivy leaf, pennyroyal (Hedeoma pulegioides, Mentha pulegium), onion, (Allium cepa), and plantain (Plantago lanceolata, P. major). None of these has been investigated in human trials, so their true efficacy for relieving coughs is unknown.

1 Star
Indigestion, Heartburn, and Low Stomach Acidity
Refer to label instructions
Elecampane has been used by herbalists to treat people with indigestion.

Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production. As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine, wormwood, gentian,dandelion, blessed thistle, yarrow, devil’s claw, bitter orange, bitter melon, juniper, andrographis, prickly ash, and centaury.. Bitters are generally taken either by mixing 1–3 ml tincture into water and sipping slowly 10–30 minutes before eating, or by making tea, which is also sipped slowly before eating.

Horehound contains a number of constituents, including alkaloids, flavonoids, diterpenes (e.g., marrubiin), and trace amounts of volatile oils. The major active constituent marrubiin and possibly its precursor, premarrubiin, are herbal bitters that increase the flow of saliva and gastric juice, thereby stimulating the appetite. Similar to horehound, elecampane has been used by herbalists to treat people with indigestion.

Carminatives (also called aromatic digestive tonics or aromatic bitters) may be used to relieve symptoms of indigestion, particularly when there is excessive gas. It is believed that carminative agents work, at least in part, by relieving spasms in the intestinal tract.

Traditional Use (May Not Be Supported by Scientific Studies)

Traditionally, herbalists have used elecampane to treat coughs, particularly those associated with bronchitis, asthma, and whooping cough.1 The herb has also been used historically to treat poor digestion and general complaints of the intestinal tract.

How It Works

Botanical names:
Inula helenium

How It Works

Elecampane root and rhizome contain approximately 1–4% volatile oils.2 Most of these volatile oils are composed of sesquiterpene lactones, including alantolactone. Elecampane is also very high in inulin (44%)3 and mucilage. Most herbal texts attribute the actions of elecampane to alantolactone.4 The antitussive (cough prevention and treatment) and carminative (soothing effect on the intestinal tract) effects of elecampane, however, may possibly be due to the inulin and mucilage content. Isolated alantolactone has been used to treat parasites (e.g., roundworm, threadworm, hookworm, whipworm). This use is only by prescription and is not approved in all European countries.5

How to Use It

The German Commission E Monograph states the historical application of elecampane has not been adequately proven to recommend its use.6 This is partially based on the potential side effects listed below. For traditional use, elecampane is typically recommended as a tea. Boiling water is poured over 1/4 teaspoon (1 gram) of the ground root and rhizome, left to steep for ten to fifteen minutes, then strained. One cup of this preparation is taken three to four times daily. Some texts recommend 1/2 to 1 teaspoon (3–5 ml) of a tincture three times daily.7

Side Effects

The inulin in elecampane root is widely distributed in fruits, vegetables and plants. It is classified as a food ingredient (not as an additive) and is considered safe to eat.8 In fact, inulin is a significant part of the daily diet of most of the world’s population.9 However, there is a report of a 39-year-old man having a life-threatening allergic reaction after consuming high amounts of inulin from multiple sources.10 Allergy to inulin in this individual was confirmed by laboratory tests. Such sensitivities are extremely rare. Moreover, this man did not take elecampane. Nevertheless, people with a confirmed sensitivity to inulin should avoid elecampane.

Alantolactone can be an irritant to the intestinal tract and, along with other sesquiterpene lactones in elecampane, may cause localized irritation in the mouth. Amounts several times higher than those stated above may cause vomiting, diarrhea, spasms, and signs of paralysis.11 If these symptoms occur, people should contact their local poison control center. Pregnant or nursing women should not use elecampane.
