LIKELY SAFE ...when the fruit is consumed orally in food amounts (13527). There is insufficient reliable information available about the safety of European barberry when used orally in medicinal amounts or when used topically.
CHILDREN: LIKELY UNSAFE
when used orally in newborns.
The berberine constituent of European barberry can cause kernicterus in newborns, particularly preterm neonates with hyperbilirubinemia (2589). There is insufficient reliable information available about the safety of European barberry when used orally in older children.
PREGNANCY: LIKELY UNSAFE
when used orally.
Berberine is thought to cross the placenta and may cause harm to the fetus. Kernicterus has developed in newborn infants exposed to berberine (2589).
LACTATION: LIKELY UNSAFE
when used orally.
Berberine and other harmful constituents can be transferred to the infant through breast milk (2589).
LIKELY SAFE ...when used orally in amounts commonly found in food.
POSSIBLY SAFE ...when used topically and appropriately (854,856,857,14000,14333). A specific 10% Oregon grape cream (Relieva, Apollo Pharmaceutical) has been used with apparent safety in studies lasting up to 12 weeks (14000,14333).

Theoretically, taking European barberry with anticholinergic drugs might cause additive effects.
Details
In vitro evidence suggests that European barberry might have anticholinergic properties (13527).
|
Theoretically, European barberry may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, taking European barberry with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Preliminary clinical evidence suggests that European barberry juice reduces fasting glucose levels in patients with type 2 diabetes who are also taking antidiabetes drugs (98575). Additionally, some animal studies show that berberine, a constituent of European barberry, has antiglycemic potential (33622,33667). Monitor blood glucose levels closely.
|
Theoretically, taking European barberry with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, taking European barberry with cholinergic drugs might decrease the effects of cholinergic drugs.
Details
In vitro evidence suggests that European barberry might have anticholinergic properties (13527).
|
Theoretically, concomitant use with drugs that have sedative properties may cause additive effects.
Details
|
Theoretically, concomitant use with cyclosporine may cause additive effects.
Details
Berberine, a constituent of European barberry, can reduce the metabolism and increase serum levels of cyclosporine. This effect is attributed to the ability of berberine to inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine (13524). Theoretically, European barberry might have a similar effect.
|
Theoretically, European barberry might increase the levels and clinical effects of CYP3A4 substrates.
Details
There is very preliminary evidence suggesting that berberine, a constituent of European barberry, might inhibit the CYP3A4 enzyme (13524). Theoretically, European barberry might have a similar effect.
|
In vitro and in vivo research suggests that berberine, a constituent of Oregon grape, can inhibit platelet aggregation (33660,33694). Theoretically, Oregon grape might have additive effects when used with anticoagulant and antiplatelet drugs and increase the risk of bleeding.
Details
Some anticoagulant and antiplatelet drugs include aspirin, cilostazol (Pletal), clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), and others.
|
Clinical research suggests that berberine, a constituent of Oregon grape, can lower blood glucose levels (20579,34247,34265,34282). Theoretically, Oregon grape might have additive effects when used with antidiabetes drugs and increase the risk of hypoglycemia.
Details
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (Diabeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
|
Animal research suggests that berberine, a constituent of Oregon grape, can have hypotensive effects (33692,34308). Also, an analysis of clinical evidence suggests that taking berberine in combination with amlodipine (Norvasc) can lower systolic and diastolic blood pressure when compared with taking amlodipine alone (91956). Theoretically, taking Oregon grape along with antihypertensive drugs might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
Details
Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDIURIL), furosemide (Lasix), and many others.
|
Animal research suggests that berberine, a constituent of Oregon grape, can have sedative effects (13519,33650,33664,33692). Theoretically, use of Oregon grape along with CNS depressants might increase the risk of additive therapeutic and adverse effects.
Details
Some CNS depressants are benzodiazepines, pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), thiopental (Pentothal), fentanyl (Duragesic, Sublimaze), morphine, propofol (Diprivan), and others.
|
Berberine, a constituent of Oregon grape, can reduce metabolism of cyclosporine and increase serum levels. It might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine (13524).
|
Preliminary clinical evidence suggests that berberine, a constituent of Oregon grape, can inhibit cytochrome P450 2C9 (CYP2C9) (34279). Theoretically, taking Oregon grape with drugs metabolized by CYP2C9 might increase drug levels and potentially increase the risk of adverse effects.
Details
Some drugs metabolized by CYP2C9 include celecoxib (Celebrex), diclofenac (Voltaren), fluvastatin (Lescol), glipizide (Glucotrol), ibuprofen (Advil, Motrin), irbesartan (Avapro), losartan (Cozaar), phenytoin (Dilantin), piroxicam (Feldene), tamoxifen (Nolvadex), tolbutamide (Tolinase), torsemide (Demadex), and S-warfarin (Coumadin).

Below is general information about the adverse effects of the known ingredients contained in the product Oregon Grape Root Strawberry Flavor. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General ...European barberry is generally well tolerated when consumed in amounts commonly found in food. A thorough evaluation of safety outcomes has not been conducted for the use of larger, medicinal amounts. Topically, European barberry seems to be well tolerated.
Hepatic ...Orally, a case of hepatitis-associated aplastic anemia is reported in an adult male after consuming European barberry 15 drops and nannari root 15 drops twice a day for 2 weeks. The patient presented with lethargy, loss of appetite, and jaundice that progressed to high-grade fevers, chills, rigors, severe pancytopenia, and abnormal liver function tests. Liver biopsy was suggestive of drug-induced liver injury. The patient was hospitalized for multiple infections and symptomatic thrombocytopenia. Despite receiving supportive care, blood transfusions, and corticosteroids, the patient died 7 weeks after diagnosis (110021). The exact reason for this adverse effect is not clear.
General ...Orally, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted. Topically, Oregon grape can cause itching, burning, skin irritation, and allergic reactions (854,14000).
Dermatologic ...Topically, Oregon grape can cause itching, burning, and skin irritation (854,14000).
Immunologic ...Topically, Oregon grape can cause allergic reactions (854,14000).
