HelloPharmacist Scorecard of Birch (Betula pendula) by Hawaii Pharm

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
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: certified organic birch extract. The liquid formula also includes vegetable palm glycerin, pharmaceutical grade alcohol, and artesian Hawaiian purified water as inactive ingredients.

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 Birch product and its label doesn't state a use — see Birch'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 we hold doesn't establish that birch works for joint pain, hair loss (alopecia), or dandruff. All three uses are rated as having insufficient reliable evidence to rate — meaning the research so far isn't strong enough to confirm whether it helps.

The evidence, ingredient by ingredient Birch

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.

Birch is generally well tolerated in food-like amounts, but allergy is a real concern. Birch pollen and birch itself can trigger allergic reactions in some people, and there's a documented case of allergic contact dermatitis from a birch bark extract cream.

Crushed birch leaves and fresh birch sap may also cause skin reactions if you're sensitive. Not enough safety data exists for pregnancy or breastfeeding — the facts advise against use in both.

Talk with your doctor or pharmacist about whether it's right for you in these situations.

Side effects, ingredient by ingredient Birch

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Birch.
  • The most serious interaction on file is rated Minor.
  • For scale: 75 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.

If you take diuretic drugs (water pills) for blood pressure, heart disease, or fluid retention, check your specific medications with the search tool below before taking this product — birch may interfere with how they work.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

Birch extract may appeal to you if you're exploring options for joint or scalp concerns, but the evidence backing those uses isn't established in our data. The main caution is a minor interaction with diuretic drugs and the real risk of allergic reactions if you're sensitive to birch pollen or birch itself.

Check with your doctor or pharmacist before starting, especially if you take water pills or have a known birch allergy.

Birch (Betula pendula) by Hawaii Pharm: Common Questions

Does Birch (Betula pendula) by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Birch (Betula pendula) has a known interaction with 75 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Birch (Betula pendula) 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 pregnant or breastfeeding?
No — the safety data advises against birch supplements during both pregnancy and breastfeeding because there isn't enough information to know it's safe. Talk with your doctor or pharmacist about your options.
Can I use this if I'm allergic to birch pollen?
You should avoid it. Birch pollen allergies often cross-react with birch itself, and this product could trigger a reaction. If you have a known birch pollen allergy, check with your doctor or pharmacist first.
What's birch extract supposed to do?
It's marketed for joint pain, hair loss, and dandruff, but we don't have reliable evidence that it works for any of these uses. The research isn't strong enough to confirm a benefit.
Does this have fillers or other added ingredients?
Yes — the liquid includes vegetable palm glycerin, pharmaceutical grade alcohol, and purified water as inactive ingredients alongside the birch extract.
Could this cause side effects?
Allergic reactions are the main concern. Some people experience reactions to birch pollen or birch products, and there's a documented case of contact dermatitis from topical birch bark extract. If you have sensitive skin or a history of birch pollen allergies, be cautious.
