HelloPharmacist Scorecard of Matricaria Spp. Chamomile by Wise Woman Herbals
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
Low disclosure
This product contains one active ingredient: German chamomile, a liquid extract. The formula also includes organic alcohol and spring water as inactive ingredients that carry the herb.
Does it work?
Couldn't assess
The evidence for chamomile's effectiveness in the conditions it's used for is not established in our data. Hay fever, anxiety, ADHD, sexual dysfunction, and cancer-related loss of appetite all show insufficient reliable evidence to rate it — meaning the science isn't there yet to confirm it works for these purposes.
If you're considering chamomile for any of these, talk with your pharmacist about what the research actually shows.
How safe is it?
Well-documented data
German chamomile is generally well tolerated by most adults, but it can trigger allergic reactions in people sensitive to ragweed and related plants — severe reactions including anaphylaxis have been reported in rare cases. When applied to skin, it may cause allergic dermatitis or eczema.
Used as an oral rinse, some people have reported nausea and burning in the mouth. Because there isn't enough reliable safety information, the data advises against use during pregnancy unless your doctor approves it.
Limited safety data exist for breastfeeding, so check with your doctor or pharmacist before using it while nursing.
Meds to double-check
Moderate interaction found
Before you take this chamomile, check with your pharmacist if you're on warfarin or any blood thinner, sedative or sleep aids, birth control pills or hormone replacement therapy, tamoxifen, or any medication that depends on liver enzymes (CYP2D6, CYP2C9, CYP3A4) to be broken down. All of these show moderate-severity interaction potential with chamomile.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Chamomile is generally well tolerated and worth considering if you're interested in herbal relaxation support. But if you take warfarin, sedatives, birth control, hormone therapy, tamoxifen, or medications processed through your liver, run this product past your pharmacist first — the interaction picture matters.
And if you're pregnant or breastfeeding, get your doctor's okay before starting.
Educational only — not medical advice; always confirm with your pharmacist. Our editorial policy · How we use AI

Matricaria Spp. Chamomile by Wise Woman Herbals Drug Interactions
HelloPharmacist Interaction Report
Wise Woman Herbals Chamomile is a single-ingredient liquid made from German chamomile, and it does interact with a number of medications.
The most serious documented interaction is with warfarin (a blood thinner). One case reported a 70-year-old taking warfarin who developed serious bleeding after drinking 4–5 cups of chamomile tea daily and using a topical chamomile lotion — her blood-clotting measure (INR) spiked to 7.9.
Read the full breakdown — every affected drug type, severity by severity
Chamomile may also cause moderate-severity interactions with sedative medications (CNS depressants), which could add to drowsiness; drugs processed by your liver's cytochrome P450 enzymes (CYP2D6, CYP2C9, and CYP3A4 substrates), potentially raising their levels in your blood; birth control pills and hormone replacement therapy, because chamomile showed antiestrogenic activity in lab tests; and tamoxifen (a cancer medication), through the same antiestrogenic mechanism.
Additionally, these theoretical enzyme and hormone interactions have not yet been reported in people — the lab evidence is there, but human cases are still absent. That said, they're a reason to check your exact medications before you start.
Altogether, these interactions span 961 individual medications.
