The Health Benefits of Chickweed

This flowering weed is thought to treat skin conditions

Chickweed, or Stellaria media (S. media), is a perennial flowering plant in the family Caryophyllaceae.

It's been used in traditional Chinese medicine to treat skin diseases and viruses.

Today, herbalists use it for conditions as diverse as the following:

Here's what you need to know about chickweed's purported uses and benefits, as well as side effects and precautions to be aware of.

Chickweed Supplement Facts

  • Active ingredients: Saponins, phenols, tannins, and flavonoids
  • Alternate names: Stellaria media
  • Legal status: Over-the-counter supplement (United States).
  • Suggested dose: Unknown
  • Safety considerations: No data for children or during pregnancy or lactation.

Uses of Chickweed

Chickweed has demonstrated anti-inflammatory and anti-viral activity in the laboratory setting.

However, there's no clinical evidence of benefit to humans.

Juice or extracts made from chickweed have been studied in test tubes or mice models for the following conditions:

  • Hepatitis B. Chickweed was shown to have anti-hepatitis B virus activity in a test tube study.
  • Obesity. Chickweed extract given to overweight mice decreased the amount of food they consumed and their absorption of fats.
  • Diabetes. Chickweed leaf extract demonstrated antidiabetic effects, such as lowering blood sugar and hemoglobin A1c, in mouse models.
  • Heart problems in people with diabetes. Chickweed tea given to diabetic rats did not improve their blood sugar levels but did seem to protect against cardiomyopathy.
  • Anxiety. Chickweed given to mice showed similar activity as diazepam, a classic anxiety medication in the benzodiazepine family.

It's important to note that these studies are all preliminary. There are no human clinical trials showing benefits from chickweed for these or other uses. Studies performed in test tubes or using animal models do not necessarily translate into benefits for humans.

Therefore robust clinical trials in humans are certainly needed before chickweed can be recommended for these or other conditions.

What Are the Side Effects of Chickweed?

Very little is known about the safety profile of chickweed.

If you decide to take it, be alert for possible side effects.

These side effects may be common or severe.

Common Side Effects

Chickweed may cause the following common side effects:

Severe Side Effects

Severe side effects of chickweed may include:

Seek immediate medical care if you experience any of these severe side effects.

Precautions

Due to a lack of safety data, chickweed is not recommended for the following:

  • Children
  • During pregnancy
  • Nursing

Nitrates in chickweed are thought to be responsible for side effects like:

  • Dizziness
  • Weakness
  • Difficulty breathing

According to the Centers for Disease Control and Prevention (CDC), the following populations are at the highest risk of harm from nitrate exposure:

  • Infants under four months
  • Pregnant people at or near the 30th week of pregnancy

Dosage: How Much Chickweed Should I Take?

Because human research is so sparse, there is no recommended chickweed dose.

If you decide to try chickweed, follow the manufacturer's recommended dose.

Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your individual needs.

What Happens If I Take Too Much Chickweed?

Never take chickweed at doses higher than recommended by the supplement manufacturers.

Components of chickweed have been associated with severe side effects like:

  • Vomiting
  • Stomach pain
  • Bluish lips or nails

If you experience these, call Poison Control at 888-222-1222 or go to your nearest emergency room.

Interactions

There's not enough information about possible interactions between chickweed and other herbal supplements, over-the-counter remedies, or prescription medications.

Based on its actions in animals, chickweed may interact with the following classes of medicines:

  • Benzodiazepines like diazepam- increased likelihood of side effects like sedation could occur due to chickweed's anti-anxiety properties seen in mice
  • Diabetes medications- hypoglycemia (low blood sugar) could occur since chickweed may also decrease blood sugar

Discuss chickweed with your healthcare provider before taking it if you are taking any medications.

It is essential to carefully read the ingredient list and nutrition facts panel of a supplement to know which ingredients and how much of each ingredient is included. Please review this supplement label with your healthcare provider to discuss any potential interactions with foods, other supplements, and medications.

How to Store Chickweed

Store chickweed supplements in a cool, dry place, away from children and animals.

Discard after one year or as directed by the manufacturer.

Sources of Chickweed & What To Look For

Chickweed may be ingested directly from the plant or taken as a supplement.

Here are some ways it can be incorporated into your diet.

Food Sources of Chickweed

Chickweed may be consumed as a raw herb in salads or made into a tea.

Chickweed Supplements

Chickweed supplements are available in pharmacies, health food stores, and online in capsule, extract, powder, salve, and ointment form.

Because the Food and Drug Administration doesn't regulate supplements, quality, and potency can vary considerably between products. Purchasing supplements assessed by an independent third party, such as ConsumerLab, NSF.org, or U.S. Pharmacopeia (USP) may be advisable. These organizations verify that the product contains the ingredients listed on the label and is free of high levels of contaminants.

Importantly, safety or efficacy is not guaranteed even with these quality assurances in place.

Summary

Although chickweed has historically been used to treat skin and respiratory conditions, it lacks evidence that it's effective in humans.

Therapeutic doses have not been determined, and we don't know how chickweed may interact with prescription or over-the-counter medicines or other herbal supplements.

For these reasons, it is not currently recommended as a treatment option for any conditions, and caution is advised.

As with all supplements, it's important to discuss using chickweed with your healthcare provider before adding it to your medicine cabinet.

Frequently Asked Questions

  • What infections might chickweed help treat?

  • Where does the chickweed plant grow?

    The plant is dispersed worldwide. It can be found throughout Asia, North America, Europe, and Africa, where it typically blooms from May to October.

  • Can I be allergic to chickweed?

    Yes. One study showed that over 2% of people in a particular area were allergic to the plant. The chickweed plant has been associated with contact dermatitis and erythema multiforme, both common skin reactions that typically heal on their own. Avoid chickweed if you're allergic or hypersensitive to it or its components (parts).
