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.

Plum Flower Astragalus is a single-ingredient capsule containing astragalus membranaceus root extract. The capsule itself is made from modified vegetable cellulose with inactive ingredients including water, dextrin, and magnesium stearate.

Does it work?

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: Qi tonifying herb in traditional Chinese medicine.
  • We looked for evidence on: Energy, Vitality, General wellness.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for astragalus is not established for the conditions listed in our data — allergic rhinitis, amenorrhea, aplastic anemia, angina, asthma, and beta-thalassemia all show insufficient reliable evidence to rate. If you're considering this product for a specific health concern, talk with your doctor or pharmacist about what the science actually supports.

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 for healthy adults, but quality human safety data is limited. Don't take it during pregnancy or while breastfeeding — there isn't enough reliable safety data to know it's safe in those situations.

A small number of people in clinical studies reported dizziness, and one person reported a type of chest pain (lacunar angina), though we can't say astragalus definitely caused either. Rapid intravenous dosing has caused temporary palpitations; skin reactions like rash and itching have been reported with IV administration.

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 immunosuppressant medications, cyclophosphamide, lithium, or any diabetes drugs. Astragalus may interfere with how these work or raise the risk of side effects like low blood sugar or lithium toxicity.

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.

Astragalus is used in traditional medicine for immune support and other purposes, but the evidence for specific conditions is limited. The main concern is its interaction with immunosuppressants, chemotherapy, lithium, and diabetes drugs — so if you take any of those, you need to check with your own doctor or pharmacist before starting it.

Short-term use in healthy people appears tolerated, but avoid it in pregnancy and while breastfeeding.

Astragalus by Plum Flower: Common Questions

Does Astragalus by Plum Flower interact with any medications?
Yes. Based on its ingredients, Astragalus 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 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.
Is astragalus safe to take while I'm pregnant or nursing?
No — there isn't enough reliable safety data. The facts advise against it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about what's right for you.
What is astragalus used for?
Astragalus is used traditionally for immune support and other conditions, but the evidence we have is insufficient to say it works for allergic rhinitis, amenorrhea, aplastic anemia, angina, asthma, or beta-thalassemia. Ask your doctor whether it's appropriate for what you're considering it for.
Can astragalus cause side effects?
A small number of people in studies reported dizziness. One person reported chest pain and rapid IV dosing has caused temporary heart palpitations. Skin reactions like rash and itching have been seen with IV administration. Overall, it's generally well tolerated short-term in healthy adults, though human safety data is limited.
Will astragalus interfere with my diabetes medication?
Possibly — astragalus may lower blood sugar on its own, so taking it with diabetes drugs could increase the risk of low blood sugar. Check with your doctor or pharmacist before adding it.
Does this product contain any fillers or additives?
Yes — the capsule contains modified vegetable cellulose, water, dextrin, and magnesium stearate as inactive ingredients. The active ingredient is astragalus membranaceus root extract.
