HelloPharmacist Scorecard of Wild Siberian Chaga by Ron Teeguarden's Dragon Herbs

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 product contains one active ingredient: chaga fruiting body extract sourced from wild Siberian mushrooms. The liquid formulation also includes water and grain alcohol 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

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

Why this rating?
  • The label markets this product for: supports glowing health and healthy aging.
  • We looked for evidence on: immune support, antioxidant support, inflammation.
  • 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, there isn't enough reliable evidence to establish whether this ingredient works for these uses.

If you're considering it for a specific health goal, it's worth talking with your pharmacist or doctor about what the research does and doesn't show.

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 is generally used in foods and teas, but human safety data are limited and some risks have been reported. A small number of cases of kidney failure and kidney inflammation have been tied to very high chaga intake, which concentrates a compound called oxalate — something to be aware of if you have kidney concerns.

There isn't enough safety information to recommend chaga during pregnancy or while breastfeeding, so it's best to avoid it during these times.
