HelloPharmacist Scorecard of Astragalus Advanced 500 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.

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 in powder form, 500 mg per capsule. Astragalus is a plant root used traditionally in herbal medicine.

The capsules also contain several inactive ingredients — pullulan polysaccharide, rice powder, bamboo extract, and rice extract blend — that serve as fillers and binders.

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 support and general wellness.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Chronic fatigue syndrome (CFS), Chemotherapy-related fatigue, Post-stroke fatigue, Heart failure, Hepatitis B — and 4 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), Heart failure, Hepatitis B, and more.

The evidence supporting astragalus for common conditions is insufficient to draw firm conclusions. We hold effectiveness data for allergic rhinitis (hay fever), amenorrhea (absent menstruation), aplastic anemia, angina, asthma, and beta-thalassemia, and for all of them the evidence is rated insufficient.

If you're considering astragalus for any of these or another condition, ask your pharmacist or doctor what the current research actually shows.

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 when taken by mouth short-term in healthy adults, though quality human safety data is limited. Some people have reported dizziness in clinical studies, and one trial noted lacunar angina (a type of chest pain), though that effect may not have been caused by the supplement itself.

The safety data advises against using astragalus during pregnancy and while breastfeeding because there isn't enough reliable information to know it's safe in those situations — talk with your doctor or pharmacist for personalized guidance if you're pregnant, planning to become pregnant, or nursing.

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 Astragalus Advanced, double-check with your pharmacist if you take immunosuppressants (such as those used after transplant), lithium (for bipolar disorder), cyclophosphamide (a chemotherapy drug), or blood sugar-lowering medications. All four carry moderate interaction risks with astragalus.

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 Advanced may be of interest to people exploring traditional herbal support, but it's important to know the evidence for specific conditions is not yet established. If you take lithium, immunosuppressants, chemotherapy, or blood sugar medications, you need to check with your pharmacist or doctor before using this product.

Pregnancy and breastfeeding require a conversation with your healthcare provider first.

Cyclophosphamide

Theoretically, astragalus might interfere with cyclophosphamide therapy.
Evidence regarding the effect of astragalus on immunosuppression caused by cyclophosphamide is conflicting. Some animal research suggests that astragalus reverses cyclophosphamide-induced immunosuppression. However, other animal research shows no effect.

Immunosuppressants

Theoretically, astragalus might interfere with immunosuppressive therapy.
Astragalus seems to stimulate immune function. Theoretically, taking astragalus might decrease the effects of immunosuppressive therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, astragalus might increase levels and adverse effects of lithium.
Animal research suggests that astragalus has diuretic properties. Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
