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.

Elderberry has shown antiviral activity and may benefit some people with common colds. Elder flowers are a traditional remedy for helping to break fevers and promote sweating during a cold.

Elderberry has shown antiviral activity and thus may be useful for some people with common colds. Elder flowers are a traditional remedy for helping to break fevers and promote sweating during a cold. In a double-blind trial, administration of an elderberry extract decreased the number of days with cold symptoms by 52% and decreased average symptom severity by 58%, compared with a placebo, in people travelling on intercontinental flights. The amount used was 600 to 900 mg per day of an extract standardized to contain 22% polyphenols and 15% anthocyanins. Treatment was begun ten days prior to the flight and was continued for four to five days after arrival at the destination.

2 Stars
Adults: 4 Tbsp daily of a syrup containing 38% elderberry extract; children: half a dose (2 Tbsp)
Supplementing with elderberry may help speed recovery.

The effect of a syrup made from the berries of the black elderberry on influenza has been studied in a small double-blind trial. People receiving an elderberry extract (four tablespoons per day for adults, two tablespoons per day for children) appeared to recover faster than did those receiving a placebo.

1 Star
Refer to label instructions
Elderberry is both immune supportive and antimicrobial.

Herbs that support a person’s immune system in the fight against microbes and directly attack microbes include the following: barberry, echinacea, elderberry, goldenseal, licorice, Oregon grape, osha, and wild indigo.

Traditional Use (May Not Be Supported by Scientific Studies)

Elderberries have long been used as food, particularly in the dried form. Elderberry wine, pie, and lemonade are some of the popular ways to prepare this plant as food. The leaves were touted by European herbalists to be pain relieving and to promote healing of injuries when applied as a poultice.1 Native American herbalists used the plant for infections, coughs, and skin conditions.

How It Works

Botanical names:
Sambucus nigra

How It Works

Flavonoids , including quercetin, are believed to account for the therapeutic actions of the elderberry flowers and berries. These flavonoids include anthocyanins that are powerful antioxidants and protect cells against damage according to test tube studies.2 According to laboratory research, an extract from the leaves, combined with St. John’s wort and soapwort, inhibits the influenza virus and herpes simplex virus.3 The effect on influenza of a syrup made from the berries of the black elderberry has been studied in a small double-blind trial.4 People receiving an elderberry extract (2 tablespoons [30 ml] per day for children, 4 tablespoons [60 ml] per day for adults) appeared to recover faster than did those receiving a placebo. Animal studies have shown the flowers to have anti-inflammatory properties.5 These actions have not been verified in human clinical trials.

How to Use It

A syrup of black elderberry extract (1 teaspoon–1 tablespoon [5–15 ml] for children, 2 teaspoons–2 tablespoons [10–30 ml] for adults) can be taken twice daily. A tea made from 1/2–1 teaspoon (3–5 grams) of the dried flowers steeped in 1 cup (250 ml) boiling water for ten to fifteen minutes may be drunk three times per day.6
