HelloPharmacist Scorecard of Goji Berry Fruit by Cedar Bear
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 liquid contains one active ingredient: goji berry fruit, delivered in a proprietary blend. The remaining ingredients are vegetable glycerin and purified water, which are inactive carriers that help deliver the goji in liquid form.
Does it work?
Couldn't assess
The evidence we hold does not establish that goji berry is effective for sunburn, cardiovascular disease, high blood pressure, weight loss, or quality of life. Each of these ratings falls short of the reliability needed to say whether it works for these purposes.
How safe is it?
Well-documented data
Goji berries as a food are generally well tolerated, though concentrated supplements have less safety data than the whole fruit. Rare cases of liver inflammation have been reported with goji supplements or goji-containing combination products, and allergic reactions — ranging from itching and swelling of the lips and throat to anaphylaxis — have occurred in some people.
During pregnancy, medicinal amounts should be avoided due to limited safety data and traditional concerns about effects on the uterus. There isn't enough reliable data to know whether supplement use is safe while breastfeeding; caution is advised and discussion with your doctor or pharmacist is warranted.
Meds to double-check
Major interaction found
Before taking this product, check with your doctor or pharmacist if you take warfarin or other blood thinners (Major concern), heart rhythm drugs like flecainide, blood pressure medications, diabetes drugs, or any prescription metabolized by your liver. Goji may slow how these drugs are cleared from your body and raise their levels.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Goji berry is mainly a concern if you take blood thinners like warfarin or heart rhythm medications — in those cases, you need to clear it with your doctor or pharmacist first. If you have a history of allergies to berries or have had liver problems, let your healthcare provider know before starting.
Talk it over with your own doctor or pharmacist to confirm it's safe alongside your current medications.

Goji Berry Fruit by Cedar Bear Drug Interactions
HelloPharmacist Interaction Report
Cedar Bear's Goji Berry Fruit Liquid interacts with medications through its goji content.
The most serious concern is warfarin (Coumadin), a blood thinner — goji can boost warfarin's effects and raise bleeding risk. We have at least 5 case reports of patients on stable warfarin doses who developed abnormally high levels when they started drinking goji juice or concentrated goji tea.
Goji appears to slow how your liver breaks down warfarin.
Read the full breakdown — every affected drug type, severity by severity
Beyond warfarin, goji may affect how your body processes several other drug types. It could theoretically slow the breakdown of blood pressure medications, diabetes drugs, heart rhythm medications like flecainide, and any drug metabolized through your liver's CYP2C19, CYP2D6, CYP2C9, or CYP3A4 pathways — though human reports of these effects are sparse or absent.
The concern is strongest for blood thinners and heart rhythm drugs, where case reports exist.
Altogether, these interactions span 1,001 individual medications. Because goji may slow your liver's ability to clear many different drug classes, you'll want to run your exact medications through the checker on this page before starting, especially if you take blood thinners, heart medications, or blood pressure drugs.

For each ingredient in Goji Berry Fruit 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.
Goji
Warfarin (Coumadin)
Goji can increase the effects of warfarin and possibly increase the risk of bleeding.
There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine. Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9).
Antihypertensive Drugs
Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.
Animal and in vitro research suggest that goji root bark has hypotensive effects. However, goji fruit juice does not appear to reduce systolic or diastolic blood pressure in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.
In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.
In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes. Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate. Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.
In vitro research shows that goji berry juice inhibits CYP2D6 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.
In vitro research shows that goji berry juice inhibits CYP3A4 enzymes. Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.
Flecainide (Tambocor)
Theoretically, goji berry might increase the levels and clinical effects of flecainide.
In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide.
Antidiabetes Drugs
Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.
Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects. However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia.
