HelloPharmacist Scorecard of Chamomile 2,000 mg by Nature's Answer
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: German chamomile flower extract at 2,000 mg. The liquid also includes purified water, vegetable glycerin, and 12–15% certified organic alcohol as inactive ingredients to deliver and preserve the extract.
Does it work?
Couldn't assess
The evidence we hold doesn't establish how well chamomile works for the uses people commonly try it for—including anxiety, hay fever, ADHD, and poor appetite related to cancer. The data shows insufficient reliable evidence to rate its effectiveness for these conditions, so we can't tell you whether it's likely to help.
How safe is it?
Well-documented data
German chamomile is generally well tolerated by most adults. However, it can trigger allergic reactions—including severe reactions and anaphylaxis in some people—especially in those sensitive to ragweed and related plants.
When used topically, it may cause allergic skin reactions or eczema; as an oral rinse, it has caused nausea and mouth burning in some cases. The safety data during pregnancy is not strong enough to recommend it, so it's best avoided in pregnancy unless your doctor approves.
For breastfeeding, the data is limited; check with your doctor or pharmacist before using it if you're nursing.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use warfarin or other blood thinners, CNS depressants like sedatives or sleep aids, oral contraceptives or hormone therapy, drugs processed through CYP2D6, CYP2C9, or CYP3A4 enzymes, or tamoxifen. Chamomile has documented or theoretical interactions with all of these.
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.
This chamomile extract might appeal to you if you're interested in herbal relaxation support, but there's no proven effectiveness data for common uses in our database. The bigger issue is medication interactions—it can affect blood thinners, sedatives, birth control, and several other drug classes.
Talk it over with your own doctor or pharmacist before starting, especially if you take any prescription medications.

Chamomile 2,000 mg by Nature's Answer Drug Interactions
HelloPharmacist Interaction Report
Chamomile 2,000 mg by Nature's Answer contains a single active ingredient—German chamomile flower extract—that does interact with medications.
The most serious concern is with warfarin (a blood thinner), where chamomile may increase its effects and raise your bleeding risk; one documented case involved significant bleeding when a patient took chamomile tea alongside warfarin.
Read the full breakdown — every affected drug type, severity by severity
Chamomile also interacts with CNS depressants (like sedatives and sleep aids), where it might add to their drowsy effects. It theoretically may slow how your body clears several classes of drugs—those processed through enzymes CYP2D6, CYP2C9, and CYP3A4—potentially raising their levels in your bloodstream.
In large amounts, chamomile may also reduce the effectiveness of oral contraceptives and estrogen-based hormone therapy, and it could interfere with tamoxifen (a breast cancer drug) through antiestrogenic activity.
Altogether, these interactions span 961 individual medications. Before starting this supplement, check your exact medications with the search tool on this page, and talk with your doctor or pharmacist if you take warfarin, any sedating drugs, birth control, hormone therapy, or tamoxifen.
