HelloPharmacist Scorecard of Astragalus 1000 mg by Herbal Secrets

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 extract at 1000 mg per capsule. The capsule itself is made from gelatin, silica, vegetable stearate, and vegetable cellulose — these are inactive ingredients that hold and deliver the astragalus.

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 system function and reduce inflammation.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Chronic fatigue syndrome (CFS), Chemotherapy-induced leukopenia, HIV/AIDS, immune support, adaptogenic stress response.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS) (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), HIV/AIDS, Chemotherapy-induced leukopenia.

The evidence we hold doesn't establish that astragalus works reliably for any condition. The data shows insufficient reliable evidence to rate it for hay fever, amenorrhea (absent periods), aplastic anemia, angina, asthma, beta-thalassemia, and other uses.

That doesn't mean it won't help — just that human studies haven't yet proven it does.

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 the short term in healthy adults, though the quality of long-term human safety data is limited. That said, a small number of people in clinical trials have reported dizziness, and there's one report of a type of angina associated with it — though that may not have been caused by the supplement itself.

Intravenous astragalus has caused temporary palpitations and rashes in some people, but you're taking this orally, so that's a different route. Don't use this during pregnancy or while breastfeeding — there isn't enough reliable safety data either way.

Talk with your doctor or pharmacist if you're pregnant, nursing, or planning to become pregnant.

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 you start astragalus, double-check with your doctor or pharmacist if you take immunosuppressants, lithium, cyclophosphamide, or diabetes medications. All of these have documented Moderate-level interactions with astragalus that could affect how your drugs work or your blood sugar control.

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 might be worth considering if you're interested in immune support, but the evidence for specific conditions is limited. If you take immunosuppressants, lithium, cyclophosphamide, or diabetes medications, you need to check with your doctor or pharmacist first — the interactions are real.

And don't take it if you're pregnant or breastfeeding.

Astragalus extract4 drug types · 208 drugs

Antidiabetes Drugs

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research in humans shows that astragalus might have hypoglycemic effects. Theoretically, taking astragalus, especially in combination with other hypoglycemic agents, might increase the risk of hypoglycemia.

Likelihood Probable Evidence A
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.

Likelihood Possible Evidence D
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.

Astragalus 1000 mg by Herbal Secrets: Common Questions

Does Astragalus 1000 mg by Herbal Secrets interact with any medications?
Yes. Based on its ingredients, Astragalus 1000 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 1000 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 this while I'm pregnant or breastfeeding?
No — the safety data isn't there. Talk with your doctor or pharmacist about alternatives or whether to wait.
What does astragalus actually do?
We hold effectiveness data for it in several conditions — hay fever, absent periods, certain types of anemia, angina, asthma, and others — but the evidence is insufficient to say whether it really works. Human research hasn't proven it yet.
Are there common side effects?
Astragalus is generally well tolerated in the short term. A small number of people in trials have reported dizziness. Long-term human safety data is limited, so we don't know all the possible effects yet.
Why does this interact with so many medications?
Astragalus appears to stimulate immune function and may have diuretic properties — both of which can interfere with how certain drugs work. The 208 individual medications affected include multiple drugs in each category (immunosuppressants, diabetes drugs, lithium, etc.), which is why the count is high.
