HelloPharmacist Scorecard of Astragalus Root by Nature's Way
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
This product contains one active ingredient: astragalus root. It's a plant used in traditional Chinese medicine.
The capsule itself is made from plant-derived material, and the capsule contains cellulose as an inactive ingredient.
Does it work?
Strong evidence
The evidence we hold on astragalus rates as insufficient to judge whether it works. Our data covers uses including hay fever, amenorrhea (absence of menstrual periods), aplastic anemia, angina, asthma, and beta-thalassemia — but for all of them, we don't have enough reliable evidence to say whether it helps or doesn't.
How safe is it?
Well-documented data
Astragalus is generally well tolerated in the short term for healthy adults, though good safety data in humans is limited. Some people have reported dizziness or, in one case, angina-like chest pain after taking it orally, though those effects may not have been caused by the supplement itself.
If you're pregnant or breastfeeding, safety data isn't strong enough — talk with your doctor before using it.
Meds to double-check
Moderate interaction found
Before starting astragalus, check your medications against immunosuppressants, lithium, cyclophosphamide, and antidiabetes drugs — all have documented moderate interactions with this ingredient. Your pharmacist can search your exact medicines on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Astragalus might be worth considering if you're interested in traditional immune support and don't take immunosuppressants, lithium, chemotherapy, or diabetes medications. If you do take any of those, check with your pharmacist first.
Because safety data is limited, pregnant and breastfeeding people should skip it.

Astragalus Root by Nature's Way Drug Interactions
HelloPharmacist Interaction Report
Astragalus Root by Nature's Way has documented moderate interactions with several medication types.
The most serious concern is with immunosuppressants — astragalus seems to stimulate your immune system, which could theoretically work against these medications and reduce their effect. If you take drugs to suppress your immune function (such as after a transplant), this matters.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take lithium for mood disorders. Animal research suggests astragalus has mild water-shedding properties that might reduce how much lithium your body clears, potentially raising its levels and side effects.
The same moderate-level concern applies to cyclophosphamide, a chemotherapy drug — evidence is mixed, but astragalus might interfere with how it works. Additionally, astragalus may lower blood sugar.
If you take diabetes medications, combining them could raise the risk of low blood sugar (hypoglycemia).
Altogether, these interactions span 203 individual medications. Use the medication checker on this page to look up your exact prescriptions before you start.

For each ingredient in Astragalus Root with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Dietary Fiber
Carbamazepine (Tegretol)
Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.
Lithium
Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.
Metformin (Glucophage)
Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
Olanzapine (Zyprexa)
Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.
Digoxin (Lanoxin)
Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.
Ethinyl Estradiol
Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.
Oral Drugs
Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.
Astragalus
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.
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.
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.
