HelloPharmacist Scorecard of American Ginseng Extract by NOW
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: American ginseng root extract. The capsule also holds two inactive ingredients—hypromellose and ascorbyl palmitate—which serve as a capsule shell and preservative.
Does it work?
Moderate evidence
American ginseng is possibly effective for upper respiratory tract infections (the common cold and similar viral infections). The evidence for other uses—anemia of chronic disease and breast cancer—is not established in our data.
How safe is it?
Well-documented data
American ginseng is generally well tolerated in the short term by healthy adults, though quality and dosage vary between products and long-term safety hasn't been well studied. Headache has been reported.
The safety data advises against use during pregnancy, and there isn't enough information to know whether it's safe while breastfeeding—talk with your doctor or pharmacist for personalized guidance on both.
Meds to double-check
Major interaction found
Before you start, check your exact medications against the list on this page if you take warfarin, immunosuppressants, diabetes drugs, or MAOIs—American ginseng can affect how these work.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.
This supplement may help with cold symptoms, but if you take warfarin, immunosuppressants, diabetes medication, or MAOIs, you'll need to check with your pharmacist first. It's not recommended in pregnancy or while nursing.

American Ginseng Extract by NOW Drug Interactions
HelloPharmacist Interaction Report
NOW's American Ginseng Extract contains a single active ingredient—American ginseng root extract—that interacts with several important medication types.
The most serious concern is with warfarin (Coumadin), a blood thinner. American ginseng appears to reduce how well warfarin works by lowering your INR (a measure of how much your blood is thinned), which could put you at risk of clotting.
Read the full breakdown — every affected drug type, severity by severity
American ginseng may also interfere with immunosuppressants (drugs that calm your immune system after transplant or for certain autoimmune conditions) by revving up immune function, potentially making those medications less effective. It can lower blood sugar, which means taking it alongside diabetes drugs might push your blood sugar too low (hypoglycemia).
There's also a theoretical risk with MAOIs (an older class of antidepressants)—a couple of case reports link ginseng use to insomnia, headache, tremors, and mood elevation when combined with these drugs.
