HelloPharmacist Scorecard of Siberian Root 500 mg by GNC Herbal Plus
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: Siberian root and rhizome powder, also called eleuthero, at 500 mg per capsule. The inactive ingredients are gelatin, microcrystalline cellulose, stearic acid, and magnesium stearate — all standard capsule fillers and binders.
Does it work?
Moderate evidence
The evidence for eleuthero is mixed and limited. It's rated possibly effective for genital herpes, meaning some evidence supports its use, but more research is needed.
For other conditions in the data we hold — familial Mediterranean fever, bipolar disorder, osteoporosis, and chronic fatigue syndrome — there isn't enough reliable evidence to rate whether it works or not.
How safe is it?
Well-documented data
Eleuthero is generally well tolerated for short-term use, but we don't have solid long-term safety data, so caution is warranted if you're planning to take it for months or longer. The most common side effects are diarrhea, upset stomach, headache, nausea, and a rash.
Some people, especially at higher doses, report nervousness, anxiety, irritability, or low mood. In one study, about 7 in 100 people taking it felt nervous.
Increased blood pressure and a faster heart rate have been reported, particularly in people with existing heart disease, though it's unclear if eleuthero itself or a contaminant was responsible. During pregnancy, there isn't enough safety data, so it's best avoided.
The same goes for breastfeeding — we don't have enough information to know it's safe.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take digoxin (Lanoxin) for your heart, blood thinners or antiplatelet drugs like warfarin or aspirin, diabetes medications, immunosuppressants, or medications broken down by your liver (CYP1A2, CYP2C9, or P-glycoprotein substrates). Eleuthero may change how these drugs work in your body.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Eleuthero may help with genital herpes, but the evidence is modest. If you take any medications — especially heart drugs, blood thinners, diabetes medications, or immune-suppressing drugs — check with your pharmacist first.
Pregnant or nursing? Skip it until you've talked with your doctor.
It's generally well tolerated short-term, but long-term safety isn't well established.

Siberian Root 500 mg by GNC Herbal Plus Drug Interactions
HelloPharmacist Interaction Report
Siberian Root 500 mg by GNC Herbal Plus contains eleuthero, which has documented interactions with a number of medication types.
The most serious concern is with digoxin (Lanoxin), a heart medication — eleuthero may raise digoxin levels in your blood and increase the risk of side effects, as shown in a case report where a patient's digoxin level climbed after starting the supplement and returned to normal after stopping it.
Read the full breakdown — every affected drug type, severity by severity
Elementhero may also interact with blood thinners and antiplatelet drugs (like warfarin or aspirin) by theoretically increasing bleeding risk, and with drugs that manage blood sugar by potentially adding to their effect and lowering your glucose too much. It may increase blood levels of medications broken down by your liver through several pathways — CYP1A2, CYP2C9, and P-glycoprotein substrates — meaning those drugs could become more potent.
Immunosuppressants (drugs that dampen your immune system) may also be affected because eleuthero stimulates immune activity.
Research in humans hasn't confirmed most of these theoretical interactions, but they're based on solid lab and animal data. One interaction with CYP2D6 substrates was tested in healthy volunteers and did not occur at the dose studied.
Altogether, these interactions span 1,123 individual medications.

For each ingredient in Siberian Root 500 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Siberian root & rhizome powder
Anticoagulant/Antiplatelet Drugs
Theoretically, eleuthero may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that a constituent of eleuthero, dihydroxybenzoic acid, appears to inhibit platelet aggregation. Concomitant use with anticoagulant or antiplatelet drugs might increase the risk of bleeding. This effect has not been reported in humans.
Antidiabetes Drugs
Theoretically, eleuthero might have additive effects when used with antidiabetes drugs.
Animal research suggests that certain constituents of eleuthero have hypoglycemic activity in both healthy and diabetic animals. A small study in adults with type 2 diabetes also shows that taking eleuthero for 3 months can lower blood glucose levels. However, one very small study in healthy individuals shows that taking powdered eleuthero 3 grams, 40 minutes prior to a 75-gram oral glucose tolerance test, significantly increases postprandial blood glucose levels when compared with placebo. These contradictory findings might be due to patient-specific variability and variability in active ingredient ratios.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP1A2.
In vitro and animal research suggest that standardized extracts of eleuthero inhibit CYP1A2. This effect has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2C9.
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2C9. This effect has not been reported in humans.
Digoxin (Lanoxin)
Eleuthero might increase serum digoxin levels and increase the risk of side effects.
In one case report, a 74-year-old male who was stabilized on digoxin presented with an elevated serum digoxin level after starting an eleuthero supplement, without symptoms of toxicity. After stopping the supplement, serum digoxin levels returned to normal. It is not clear whether this was due to a pharmacokinetic interaction or to interference with the digoxin assay. Although the product was found to be free of digoxin and digitoxin, it was not tested for other contaminants.
Immunosuppressants
Theoretically, eleuthero might interfere with immunosuppressive drugs because of its immunostimulant activity.
Animal and in vitro research shows that eleuthero extracts have immunomodulatory effects, including increasing cellular and humoral activity.
P-Glycoprotein Substrates
Theoretically, eleuthero might increase levels of P-glycoprotein substrates.
In vitro research suggests that eleuthero can inhibit the multi-drug transporter protein, P-glycoprotein. However, it is too soon to tell if this is clinically important. This interaction has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2D6.
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2D6. However, research in healthy human volunteers has found that taking eleuthero 485 mg twice daily for 14 days does not inhibit CYP2D6 drug metabolism.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP3A4.
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP3A4. However, research in healthy human volunteers has found that taking eleuthero 485 mg twice daily for 14 days does not inhibit CYP3A4 drug metabolism.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Theoretically, eleuthero might decrease levels of drugs metabolized by OATP.
In vitro research suggests that eleuthero inhibits OATP2B1, which might reduce the bioavailability of oral drugs that are substrates of OATP2B1. Due to the weak inhibitory effect identified in this study, this interaction is not likely to be clinically significant.
