HelloPharmacist Scorecard of Cold Season Support Alcohol Free by Herbal Terra
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
Cold Season Support Alcohol Free contains 2 active ingredients: Astragalus Root Extract and Goldenseal Leaf Extract, Dry. These are combined in a proprietary blend and delivered in liquid form.
The product also contains glycerin and water as inactive ingredients.
Does it work?
Not established
The evidence supporting these ingredients is limited. For Astragalus, we hold insufficient reliable evidence to rate its effectiveness for allergic rhinitis (hay fever), amenorrhea, aplastic anemia, angina, asthma, and beta-thalassemia.
For Goldenseal, the evidence is similarly insufficient for acne, allergic rhinitis, anorexia nervosa, and chronic fatigue syndrome; one study found it possibly ineffective for masking urine drug tests.
How safe is it?
Well-documented data
Astragalus is generally well tolerated short-term in healthy adults, though human safety data are limited. A small number of people have reported dizziness, and one clinical trial associated it with chest pain—though astragalus may not have caused this.
The safety data advises against astragalus during pregnancy and while breastfeeding. Goldenseal is generally used short-term by healthy adults, but human safety data are limited.
The safety data advises against goldenseal during pregnancy because berberine (a component) may harm the fetus and trigger contractions, and while breastfeeding because berberine may pass to your baby. Orally, it may cause abdominal pain or distension, diarrhea or constipation, flatulence, headache, nausea, vomiting, and a bitter taste.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take any of these: immunosuppressants or cyclophosphamide, lithium, diabetes medications, CNS depressants (sedatives and sleep aids), antihypertensive drugs (blood pressure medications), anticoagulant or antiplatelet drugs (blood thinners), or any drug your liver metabolizes—which includes heart medications, antifungals, and many others.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This product is not suitable if you take immunosuppressants, chemotherapy, lithium, diabetes medications, sedatives, blood pressure medications, blood thinners, or drugs your liver breaks down via specific pathways—which is a very long list. Do not use during pregnancy or while breastfeeding.
Talk to your pharmacist or doctor before starting, especially if you take any prescription medication.

For each ingredient in Cold Season Support Alcohol Free 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.
Goldenseal Leaf Extract, Dry
Anticoagulant/Antiplatelet Drugs
Theoretically, goldenseal might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Goldenseal contains berberine. In vitro and animal research shows that berberine can inhibit platelet aggregation. However, this effect has not been reported in humans.
Antidiabetes Drugs
Theoretically, goldenseal might increase the risk of hypoglycemia when used with antidiabetes drugs.
Goldenseal contains berberine. Clinical research shows that berberine can lower blood glucose levels. However, this effect has not been reported with goldenseal.
Antihypertensive Drugs
Theoretically, goldenseal might increase the risk of hypotension when taken with antihypertensive drugs.
Goldenseal contains berberine. Animal research shows that berberine can have hypotensive effects. Also, an analysis of clinical research shows that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone. However, this effect has not been reported with goldenseal.
Cns Depressants
Theoretically, goldenseal might increase the sedative effects of CNS depressants.
Goldenseal contains berberine. Animal research shows that berberine can have sedative effects. However, this effect has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2C9.
In vitro research shows that goldenseal root extract can modestly inhibit CYP2C9. This effect may be due to its alkaloid constituents, hydrastine and berberine. However, this effect has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Goldenseal might increase serum levels of drugs metabolized by CYP2D6.
Clinical and in vitro research shows that goldenseal can significantly inhibit CYP2D6 enzymes, potentially increasing levels of drugs metabolized by CYP2D6.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2E1.
In vitro research shows that goldenseal root extract can inhibit the activity of CYP2E1. However, this effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Goldenseal might increase serum levels of drugs metabolized by CYP3A4.
Most clinical and in vitro research shows that goldenseal inhibits CYP3A4 enzyme activity and increases serum levels of CYP3A4 substrates, such as midazolam. However, in one small clinical study, goldenseal did not affect the levels of indinavir, a CYP3A4 substrate, in healthy volunteers. This is likely due to the fact that indinavir has a high oral bioavailability, making it an inadequate probe for CYP3A4 interactions and/or that it is primarily metabolized by hepatic CYP3A, while goldenseal has more potential to inhibit intestinal CYP3A enzyme activity. Both goldenseal extract and its isolated constituents berberine and hydrastine inhibit CYP3A, with hydrastine possibly having more inhibitory potential than berberine.
Dextromethorphan (Robitussin Dm, Others)
Theoretically, goldenseal might increase serum levels of dextromethorphan.
Goldenseal contains berberine. A small clinical study shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan.
Digoxin (Lanoxin)
Goldenseal might increase serum levels of digoxin, although this effect is unlikely to be clinically significant.
Clinical research shows that goldenseal modestly increases digoxin peak levels by about 14% in healthy volunteers. However, goldenseal does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC). This suggests that goldenseal does not cause a clinically significant interaction with digoxin. Digoxin is a P-glycoprotein substrate. Some evidence suggests that goldenseal constituents might affect P-glycoprotein; however, it is unclear whether these constituents inhibit or induce P-glycoprotein.
Losartan (Cozaar)
Theoretically, goldenseal might decrease the conversion of losartan to its active form.
Goldenseal contains berberine. A small clinical study shows that berberine inhibits cytochrome P450 2C9 (CYP2C9) activity and reduces the metabolism of losartan. However, this effect has not been reported with goldenseal.
Metformin (Glucophage)
Theoretically, goldenseal might reduce blood levels of metformin.
In vitro research shows that goldenseal extract decreases the bioavailability of metformin, likely by interfering with transport, intestinal permeability, or other processes involved in metformin absorption. It is unclear which, if any, of metformin's transporters are inhibited by goldenseal. Goldenseal does not appear to alter the clearance or half-life of metformin.
P-Glycoprotein Substrates
Theoretically, goldenseal might increase or decrease serum levels of P-glycoprotein (P-gp) substrates.
There is conflicting evidence about the effect of goldenseal on P-gp. In vitro research suggests that berberine, a constituent of goldenseal, modestly inhibits P-gp efflux. Other evidence suggests that berberine induces P-gp. In healthy volunteers, goldenseal modestly increases peak levels of the P-gp substrate digoxin by about 14%. However, it does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC). This suggests that goldenseal is not a potent inhibitor of P-gp-mediated drug efflux. Until more is known, goldenseal should be used cautiously with P-gp substrates.
Pentobarbital (Nembutal)
Theoretically, goldenseal might increase the sedative effects of pentobarbital.
Animal research shows that berberine, a constituent of goldenseal, can prolong pentobarbital-induced sleeping time. However, this effect has not been reported with goldenseal.
Tacrolimus (Prograf)
Theoretically, goldenseal might increase serum levels of tacrolimus.
Goldenseal contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of tacrolimus dosing to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL.
Oseltamivir (Tamiflu)
Theoretically, goldenseal might reduce the therapeutic effects of oseltamivir by decreasing its conversion to its active form.
In vitro evidence suggests that goldenseal reduces the formation of the active compound from the prodrug oseltamivir. The mechanism of action and clinical relevance is unclear.
Astragalus Root Extract
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.
