HelloPharmacist Scorecard of Stamina Formula 450 mg by TerraVita Premium Collection
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
Low disclosure
This formula has 3 active ingredients. Damiana is an herb traditionally used for sexual function and mood, though we don't yet have reliable evidence it works for these purposes.
Witch hazel is a plant extract best known as a topical remedy for hemorrhoids—it's possibly effective for that use—but it's designed to be applied to skin, not taken by mouth in a capsule. Eleuthero (also called Siberian ginseng) is an herbal adaptogen sometimes used for fatigue and immune support, with some evidence it may help genital herpes.
The capsule also contains gelatin and water as inactive ingredients.
Does it work?
Moderate evidence
The evidence for this product's purpose isn't established in our data. Damiana has insufficient reliable evidence for sexual dysfunction, asthma, headache, cognitive function, constipation, and depression.
Eleuthero shows some promise for genital herpes, but lacks solid evidence for familial Mediterranean fever, bipolar disorder, osteoporosis, and chronic fatigue syndrome. Witch hazel is possibly effective for hemorrhoids when used topically, but there's no evidence data for it taken by mouth as this product is formulated.
How safe is it?
Well-documented data
Damiana is likely fine in small amounts but human safety data are limited, and it should be avoided during pregnancy and while breastfeeding. Witch hazel is generally well tolerated on skin short-term but is not meant to be taken by mouth—one ingredient of concern is its tannin content, which at high doses and over time could theoretically damage your kidneys or liver.
Eleuthero is generally well tolerated short-term, though some people report nervousness (reported in about 7% of users in one study), headache, nausea, and gastrointestinal upset, especially at higher doses; it should be avoided during pregnancy and breastfeeding. In rare cases, eleuthero has been linked to increased blood pressure and heart-related effects, though it's unclear whether eleuthero itself or contamination in supplements caused these.
Meds to double-check
Moderate interaction found
Before taking Stamina Formula 450 mg, double-check these medication types with your pharmacist: antidiabetes drugs (from both damiana and eleuthero), blood thinners or antiplatelet drugs, digoxin (Lanoxin), immunosuppressants, and drugs processed by your liver's CYP1A2, CYP2C9, and CYP2D6 pathways (from eleuthero). These carry Moderate or Minor interaction risks.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product combines three herbal ingredients with limited human safety data and multiple medication interactions. If you take antidiabetes drugs, blood thinners, heart medications like digoxin, or drugs metabolized by your liver, talk to your pharmacist before starting—the interactions could be significant.
Pregnant or breastfeeding individuals should avoid all three ingredients. Check your exact medications with the tool on this page.

Stamina Formula 450 mg by TerraVita Premium Collection Drug Interactions
HelloPharmacist Interaction Report
Stamina Formula 450 mg by TerraVita Premium Collection contains three active ingredients, and two of them interact with medications.
Damiana poses a Moderate interaction risk with antidiabetes drugs—it may lower blood sugar (glucose) level, which could increase the risk of low blood sugar (hypoglycemia) if you're also taking diabetes medications. Eleuthero carries Moderate interactions with several drug types: it may increase levels of medications broken down by your liver's CYP1A2, CYP2C9, and P-glycoprotein pathways, and it may theoretically interfere with blood thinners (anticoagulant or antiplatelet drugs) and immunosuppressants.
Eleuthero also has a documented case of raising digoxin (Lanoxin) levels in one patient; it may lower blood sugar with antidiabetes drugs; and it carries a Minor interaction with drugs metabolized by CYP2D6, though human studies suggest this is unlikely at typical doses.

Witch hazel, the third ingredient, has no known interactions documented in our data. Altogether, these interactions span 1,123 individual medications.

For each ingredient in Stamina Formula 450 mg 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.
Eleuthero
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.
Damiana
Antidiabetes Drugs
Theoretically, taking damiana with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that taking damiana lowers blood glucose level.
