What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: German chamomile, an herbal extract in liquid form. The inactive ingredients are alcohol and distilled water.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient German Chamomile product and its label doesn't state a use — see German Chamomile's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for German chamomile's effectiveness for any condition is insufficient in the data we hold. It has been studied for hay fever, anxiety, ADHD, sexual dysfunction, and cancer-related loss of appetite, but reliable evidence supporting its use for these purposes is not established.

The evidence, ingredient by ingredient German Chamomile

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

German chamomile is generally well tolerated in most adults, but it can cause allergic reactions in people who are sensitive to ragweed and related plants—some cases of severe hypersensitivity reactions and anaphylaxis have been reported. Topically, it may cause allergic dermatitis and eczema.

When used as an oral rinse, some people have reported nausea and burning in the mouth. During pregnancy, safety data are not sufficient, so it's best avoided unless your doctor approves.

While breastfeeding, limited safety data exist; check with your doctor or pharmacist before using.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — German Chamomile.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 961 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check with your doctor or pharmacist if you take warfarin or another blood thinner (risk of increased bleeding), CNS depressants like sedating medications (risk of added drowsiness), oral contraceptives or estrogen therapy (risk of reduced effectiveness), tamoxifen (risk of reduced cancer-drug effectiveness), or any medication broken down by your liver, such as certain heart, diabetes, or psychiatric drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Chamomile extract is generally well tolerated in most people, but its interactions with blood thinners, sedating medications, hormonal drugs, and liver-metabolized medications are a real concern. If you take any prescription medication—especially warfarin, sleep aids, birth control, hormone therapy, or tamoxifen—check with your doctor or pharmacist before adding this product.

People with ragweed allergies should avoid it.

Chamomile Flowers Extract by Oregon's Wild Harvest: Common Questions

Does Chamomile Flowers Extract by Oregon's Wild Harvest interact with any medications?
Yes. Based on its ingredients, Chamomile Flowers Extract has a known interaction with 960 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Chamomile Flowers Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm on birth control or hormone replacement therapy?
Theoretically, large amounts of German chamomile may interfere with how your birth control or hormone therapy works through an antiestrogenic effect. This isn't confirmed in humans yet, but it's a real concern. Talk with your doctor or pharmacist before using this product if you rely on hormonal contraception or hormone replacement.
What if I'm allergic to ragweed?
You should avoid this product. German chamomile can trigger allergic reactions in people sensitive to ragweed and related plants, including severe reactions in rare cases.
Is this safe during pregnancy?
There isn't enough reliable safety information, so it's best avoided during pregnancy unless your doctor approves. Talk with your doctor before using it.
Can I use this while breastfeeding?
Limited safety data exist for breastfeeding. Check with your doctor or pharmacist before using this product while nursing.
Does this actually work for anxiety or sleep?
The evidence we hold is insufficient to say whether German chamomile reliably helps anxiety or other conditions. While it has mild sedative properties, we don't have established proof of effectiveness for these uses.
What side effects might I notice?
Most people tolerate it well, but allergic reactions can occur—including sneezing, itchy eyes, or in rare cases severe hypersensitivity. When used as an oral rinse, some people report nausea or mouth burning. If you have a ragweed allergy, the risk is higher.
