German chamomile (Matricaria chamomilla) is a flowering plant in the Asteraceae family.

The herb smells slightly like an apple, which may explain its name—chamomile is Greek for "ground apple."

An herbal "cure-all" used for thousands of years, today chamomile is a popular supplement for irritated skin, anxiety, and insomnia. However, research is somewhat limited.

Here's what you need to know about the potential uses and benefits of German chamomile, along with some side effects and precautions to be aware of.

Dietary supplements are not regulated like drugs in the United States, meaning the Food and Drug Administration (FDA) does not approve them for safety and effectiveness before products are marketed. Choose a supplement tested by a trusted third party, such as USP, ConsumerLab, or NSF, when possible. However, even if supplements are third-party tested, that doesn't mean they are necessarily safe for all or effective in general. Therefore, it is important to talk to your healthcare provider about any supplements you plan to take and check in about potential interactions with other supplements or medications.

Uses of German Chamomile

Supplement use should be individualized and vetted by a healthcare professional, such as a registered dietitian, pharmacist, or healthcare provider. No supplement is intended to treat, cure, or prevent disease.

Some clinical trials suggest German chamomile may be beneficial for sleep disorders, anxiety, and wound healing. Here's a look at the scientific evidence.

Insomnia

German chamomile may be best known as a sleep aid, but there needs to be more solid research supporting its effectiveness for this indication.

A study was conducted in older adults in nursing homes. Sleep quality improved when participants were given 400-milligram capsules of German chamomile twice a day for four weeks, compared to those who didn't receive any treatment.

Another study was conducted in people assigned female at birth who had just given birth. It found that those who drank one cup of chamomile tea a day for two weeks had fewer sleep problems and symptoms of depression compared to a control group that didn't drink the tea. However, the improvement disappeared four weeks after the women stopped drinking the tea.

Anxiety

Limited research has shown German chamomile may have benefits when it comes to reducing anxiety, but more robust clinical trials are needed.

For example, in one study, chamomile was shown to be effective in reducing symptoms of generalized anxiety disorder (GAD) in 58% of people who took it.

Adults with GAD were given 1,500 milligrams (mg) of German chamomile for 12 weeks. There were then assigned to another 26 weeks of chamomile treatment or a placebo.

Those taking long-term chamomile had fewer GAD symptoms at the end of the trial, but there wasn't a significant decrease in relapse rate.

Wound Healing

Topical (on the skin) chamomile may help speed wound healing. However, more research is needed to determine its effectiveness.

Chamomile compresses were applied twice a day to lesions around stoma sites proved superior to 1% hydrocortisone ointment in one study.

The wounds treated with chamomile healed five to six days faster than those treated with hydrocortisone, and resulted in less pain and itching.

More studies are needed.

Additional Uses

German chamomile has also been studied for the following conditions, though the research is minimal:

More well-designed studies on German chamomile's effectiveness are needed to recommend it for any of these uses.

Side effects may include the following:

Severe Side Effects

Anaphylaxis, a life-threatening allergic reaction is possible with chamomile.

Please seek immediate medical attention if you develop symptoms of a severe allergy.

Also, note that, in general, the safety of supplements in pregnant people, nursing mothers, and children has not been well established.

Dosage: How Much German Chamomile Should I Take?

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

There is no standard dosage of chamomile. Dosages used in studies vary.

For instance, 400 milligrams (mg) twice daily has been studied to improve sleep quality in older adults.

And 1,500 milligrams of German chamomile extract were taken daily for up to 38 weeks in a clinical trial for anxiety in adults.

What Happens If I Take Too Much German Chamomile?

German chamomile appears safe for adults at high doses of up to 1,500 milligrams daily for up to 38 weeks.

Similar rates of side effects were seen in people who took chamomile and placebo (around 8%), and all side effects were mild.

No toxicity data are available for doses higher than this or for chamomile that is used longer than 38 weeks.

Interactions

Chamomile interactions with the following medications have been reported:

  • Coumadin (Warfarin)-increased risk of bleeding
  • Cyclosporine

In addition, ingredients in German chamomile have been found to inhibit liver enzymes called cytochrome P450. Medications that are broken down by these enzymes may be affected by chamomile. A few examples of these medications include the following:

  • Ciprofloxacin (Cipro)
  • Gemfibrozil
  • Fluoxetine (Prozac)
  • Carbamazepine (Tegretol)
