HelloPharmacist Scorecard of Astragalus 450 mg 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 16, 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: Astragalus Root Extract as a powder, 450 mg per capsule. The capsule also holds inactive ingredients — pullulan polysaccharide (the capsule shell), rice powder, bamboo extract powder, and a rice extract blend — which are fillers and binders to hold the supplement together.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Astragalus's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune function and energy support.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Chronic fatigue syndrome (CFS), Chemotherapy-related fatigue, Post-stroke fatigue, Respiratory health, Stamina — and 2 related terms.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-related fatigue (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Upper respiratory tract infection (URTI), Post-stroke fatigue.

The evidence for astragalus isn't yet established for the conditions studied. Our data shows insufficient reliable evidence to rate it for allergic rhinitis (hay fever), amenorrhea, aplastic anemia, angina, asthma, and beta-thalassemia.

That doesn't mean it doesn't work — it means human studies haven't been robust enough yet to confirm benefit for these uses.

The evidence, ingredient by ingredient Astragalus

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.

Astragalus is generally well tolerated in short-term use in healthy adults, though quality safety data in humans is limited. Some people in clinical trials have reported dizziness or temporary heart palpitations, though these effects may not have been caused by the supplement itself.

The safety data advises against use during pregnancy and while breastfeeding because there isn't enough reliable information to know it's safe.

Side effects, ingredient by ingredient Astragalus

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 — Astragalus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 208 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.

Before taking this product, check with your doctor or pharmacist if you take immunosuppressants (Moderate), lithium (Moderate), cyclophosphamide (Moderate), or diabetes medications (Moderate). Astragalus might interfere with how these work or raise drug levels.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Astragalus may appeal to you if you're interested in immune support, but it's not proven for specific conditions yet. If you take any prescription medications — especially immunosuppressants, lithium, chemotherapy drugs, or diabetes medications — clear this with your doctor or pharmacist first.

It's not recommended in pregnancy or while breastfeeding.

Astragalus 450 mg by Ron Teeguarden's Dragon Herbs: Common Questions

Does Astragalus 450 mg by Ron Teeguarden's Dragon Herbs interact with any medications?
Yes. Based on its ingredients, Astragalus 450 mg has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Astragalus 450 mg 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 Astragalus if I'm pregnant or breastfeeding?
No, the safety data advises against it. There isn't enough reliable information to know whether it's safe during pregnancy or while breastfeeding, so talk with your doctor or pharmacist about whether it's right for you.
What is astragalus supposed to do?
Astragalus root has been studied for conditions like hay fever, asthma, anemia, and angina, but the evidence isn't established yet — we don't have strong enough human research to confirm it works for any of these.
Are there any side effects?
It's generally well tolerated, but a small number of people in clinical trials reported dizziness or temporary heart palpitations — though these may not have been caused by astragalus itself. Quality safety data in humans is limited.
I take diabetes medication. Is it safe to add this?
Not without checking first. Astragalus might lower blood sugar further on top of your medication, raising the risk of low blood sugar. Talk to your doctor or pharmacist before starting it.
I'm on immunosuppressants after a transplant. Can I use this?
You'll need to check with your doctor first. Astragalus appears to boost immune function, which could interfere with how your transplant medication works.
