HelloPharmacist Scorecard of Astragalus by Oregon's Wild Harvest

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

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: fresh Biodynamic and organic Astragalus root. It's delivered as a liquid extract, which means the herb is concentrated in an alcohol base (also organic and Biodynamic).

The alcohol serves as a preservative and extraction medium to pull out the plant's active compounds.

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: healthier immune response.
  • We looked for evidence on: Upper respiratory tract infection (URTI), Allergic rhinitis (hay fever), Asthma, HIV/AIDS, Hepatitis B, Systemic lupus erythematosus (SLE) — and 4 related terms.
  • The closest evidence on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Astragalus is rated "Insufficient Reliable Evidence To Rate" for Asthma, Upper respiratory tract infection (URTI), Hepatitis B, HIV/AIDS, and more.

The evidence for astragalus is still being built. Our data rates its effectiveness as insufficient for conditions like hay fever, amenorrhea (absent periods), aplastic anemia, angina, asthma, and beta-thalassemia — meaning the research so far isn't strong or complete enough to say whether it works.

If you're considering astragalus for a specific health concern, talk with your doctor or pharmacist about what the current evidence 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, but good human safety data is limited. The most common reported effects have been dizziness and, rarely, angina-like chest pain or rash — though these may not have been caused by astragalus itself.

Intravenous forms (which this product is not) can cause temporary palpitations or dizziness. Don't use astragalus during pregnancy or while breastfeeding — there isn't enough reliable safety data in either situation.

Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, planning to become pregnant, or nursing.

Side effects, ingredient by ingredient Astragalus

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.

Check with your doctor or pharmacist before using this product if you take immunosuppressants (drugs to prevent transplant rejection or manage severe autoimmune disease), lithium, diabetes medications, or cyclophosphamide. All four have Moderate-severity theoretical interactions 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.

Oregon's Wild Harvest Astragalus may interest you if you're exploring immune support, but the evidence for specific conditions isn't established yet. If you take immunosuppressants, lithium, diabetes drugs, or cyclophosphamide, you'll need to check with your doctor or pharmacist before starting — the interactions are theoretical but worth taking seriously.

fresh Biodynamic & organic Astragalus4 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 by Oregon's Wild Harvest: Common Questions

Does Astragalus by Oregon's Wild Harvest 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.
Can I take this while pregnant or breastfeeding?
Not based on the safety data we have. There isn't enough reliable information to know it's safe during pregnancy or while breastfeeding, so it's best avoided in both situations. Talk with your doctor or pharmacist about your specific situation.
Does astragalus actually work for anything?
The evidence isn't established in our data. Astragalus has been studied for conditions like hay fever, asthma, and anemia, but the research so far isn't strong or complete enough to say it works. Your doctor can discuss what research exists for your particular concern.
What are the side effects I should watch for?
Most people tolerate it well short-term. Dizziness and rash have been reported in rare cases, and one trial noted angina-like chest pain, though it's unclear whether astragalus caused these. If you notice any unusual symptoms, tell your pharmacist or doctor.
Why is there alcohol in this liquid?
The alcohol is organic and Biodynamic, like the astragalus itself. It's used to extract the plant's active compounds and preserve the product. If you need to avoid alcohol, you may want to ask your pharmacist about other astragalus forms.
Will this interfere with my diabetes medication?
Possibly. Astragalus can lower blood sugar on its own, so combined with your diabetes medication it could increase the risk of low blood sugar (hypoglycemia). Check with your doctor or pharmacist before starting — they may want to monitor your blood sugar more closely.
I take a drug to prevent transplant rejection. Can I use this?
You'll need to talk with your doctor first. Astragalus seems to boost immune function, which could theoretically reduce how well your immunosuppressant works. That's a serious concern, so clear it with your own healthcare provider before taking any astragalus product.
