HelloPharmacist Scorecard of Wild Siberian Chaga by Raw Forest Foods

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 powder contains one active ingredient: chaga fruiting body extract. Chaga is a fungus that grows on birch trees; the extract concentrates its bioactive compounds.

There are no other inactive ingredients listed.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: immune support and antioxidant tonic.
  • We looked for evidence on: immune function, antioxidant defense, general wellness.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence we hold on chaga is limited. For cardiovascular disease, diabetes, and COVID-19, the data aren't yet strong enough to rate whether it works.

You won't find claims here about what this supplement can or can't do for any health condition — that's because the science hasn't established those answers yet.

The evidence, ingredient by ingredient Chaga

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.

Chaga has been used in foods and teas for a long time, but human safety studies are sparse and a few risks have been noted. The main concern is oxalate content: there have been rare reports of kidney failure and kidney damage tied to very high chaga consumption.

If you have a history of kidney stones or kidney disease, this is worth discussing with your doctor before you start. The safety data also advise against use during pregnancy and while breastfeeding because there isn't enough information to know whether it's safe in those situations.

Side effects, ingredient by ingredient Chaga

Meds to double-check

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 — Chaga.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 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 blood thinners or antiplatelet drugs (like warfarin or aspirin), immunosuppressant medications, or antidiabetes drugs, check your specific medication with the tool on this page before adding chaga. The interactions are theoretical but documented in our data.

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 is a single-ingredient chaga extract with theoretical interactions involving blood thinners, immune suppressants, and diabetes drugs—none yet confirmed in humans. If you take any of those medication types, run this through the interaction checker before you start.

Anyone with kidney concerns should also talk to their pharmacist or doctor first.

Wild Siberian Chaga by Raw Forest Foods: Common Questions

Does Wild Siberian Chaga by Raw Forest Foods interact with any medications?
Yes. Based on its ingredients, Wild Siberian Chaga has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Wild Siberian Chaga 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 while pregnant or breastfeeding?
The safety data advise against it—there isn't enough information to know whether chaga is safe in pregnancy or while breastfeeding. Talk with your doctor or pharmacist about what's right for your situation.
Is chaga safe if I have kidney problems?
Chaga is high in oxalate, and there have been rare reports of kidney damage from very high consumption. If you have kidney stones, kidney disease, or a history of either, discuss this supplement with your doctor before starting.
What does chaga actually do?
We don't have strong enough evidence to confirm what chaga does for any specific health condition. The evidence for cardiovascular health, blood sugar control, and COVID-19 is currently rated insufficient, so we can't say it works for those purposes.
Is this powder pure chaga with no fillers?
Yes—there are no inactive ingredients listed. You're getting chaga fruiting body extract and nothing else.
How much chaga is safe to take?
Our data don't specify a safe dose. Given the oxalate content and rare reports of kidney problems with excessive use, this is a good question for your pharmacist, especially if you plan to use it regularly.
