INSUFFICIENT RELIABLE EVIDENCE to RATE

• Alzheimer disease. Although there has been interest in using oral black currant berry for Alzheimer disease, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Atopic dermatitis (eczema). Topical black currant seed oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in children aged 2-18 years with atopic dermatitis shows that using a specific cream containing black currant seed oil, sunflower oil, and balloon vine (Defensil), with added dexpanthenol and ceramide, twice daily for 4 weeks, improves atopic dermatitis severity scores similarly to urea 5% cream. About 38% of patients had a 50% improvement in severity score with the combination cream, compared with 35% with urea cream (105538).
• Colic. Although there has been interest in using oral black currant leaf for colic, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Common cold. Although there has been interest in using oral black currant berry for common cold, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Cough. Although there has been interest in using oral black currant leaf for cough, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Diarrhea. Although there has been interest in using oral black currant leaf for diarrhea, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Dry eye. Oral black currant has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in adults with dry eye disease shows that taking a specific combination product containing black currant 100 mg, L-carnitine 50 mg, elderberry fruit extract 300 mg, zinc 10 mg, and Eleutherococcus root 50 mg (Meramirt CM) orally once daily improves dry eye symptom scores when compared with no intervention. Contrast sensitivity scores also improved when compared with baseline in the treated group, but not in the control group (111295). It is unclear if this effect is due to black currant, other ingredients, or the combination.
• Dysmenorrhea. Although there has been interest in using oral black currant seed oil for dysmenorrhea, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Glaucoma. It is unclear if oral black currant is beneficial in patients with glaucoma. Details: Preliminary clinical research in adults with glaucoma shows that taking black currant anthocyanins 50 mg orally daily for 4 weeks decreases intraocular pressure (IOP) by 1.5 mmHg when compared with placebo (93696). However, other preliminary clinical research in patients with open-angle glaucoma shows that taking black currant anthocyanins 50 mg orally daily along with standard medications for glaucoma for 24 months does not improve IOP when compared with placebo (93695). Preliminary subgroup analyses suggest that patients taking one or less antiglaucoma medications, but not more than one, may benefit the most from black currant (93695,93696).
• Gout. Although there has been interest in using oral black currant leaf for gout, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Hyperlipidemia. It is unclear if oral black currant seed oil is beneficial in patients with hyperlipidemia. Details: Preliminary clinical research in adults with hyperlipidemia shows that taking black currant seed oil 18 grams orally twice daily for 6 weeks reduces total cholesterol by about 16%, reduces triglycerides by about 34%, and increases high-density lipoprotein (HDL) cholesterol by about 35% when compared with baseline (17638). However, the validity of this study is limited by the lack of a comparator group.
• Hypertension. It is unclear if oral black currant seed oil is beneficial in patients with hypertension. Details: Preliminary clinical research in males with borderline hypertension shows that taking black currant seed oil 6 grams orally daily for 8 weeks does not reduce blood pressure when compared with safflower oil 6 grams daily. However, when stress is induced by a mental arithmetic exercise, black currant seed oil appears to induce a 40% reduction in systolic and diastolic blood pressure elevations in these patients (35994).
• Influenza. Although there has been interest in using oral black currant berry for influenza, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Insect bite. Although there has been interest in using topical black currant leaf for insect bite, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Japanese cedar pollinosis. It is unclear if oral black currant extract is beneficial in patients with Japanese cedar pollinosis. Details: Preliminary clinical research in patients with Japanese cedar pollinosis shows that taking a black currant polysaccharide extract 540 mg orally twice daily for 8 weeks does not improve nasal symptom scores or swelling when compared with placebo (17635).
• Liver disease. Although there has been interest in using oral black currant leaf for liver disease, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Menopausal symptoms. Although there has been interest in using oral black currant seed oil for menopausal symptoms, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Muscle fatigue. It is unclear if oral black currant juice extract is beneficial in patients with muscle fatigue. Details: Preliminary clinical research in office workers shows that black currant juice extract, containing 10.83% anthocyanins, taken once orally and dosed as anthocyanins 17 mg/kg, reduces muscle stiffness scores after typing for 30 minutes when compared with placebo (17633).
• Osteoarthritis. Although there has been interest in using oral black currant leaf for osteoarthritis, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Peripheral arterial disease (PAD). Although there has been interest in using oral black currant juice for PAD, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Premenstrual syndrome (PMS). Although there has been interest in using oral black currant seed oil for PMS, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Rheumatoid arthritis (RA). It is unclear if oral black currant seed oil is beneficial in patients with RA. Details: A small clinical study in patients with RA shows that taking black currant seed oil 10.5 grams orally daily for 24 weeks reduces tenderness scores when compared with placebo (35990).
• Rhinosinusitis. Oral black currant has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients over 12 years of age with chronic sinusitis shows that taking a combination product containing black currant, Boswellia serrata, bromelain, and vitamin D (Flogostop Forte, Humana Italia) with inhaled corticosteroids daily for 30 days reduces rhinorrhea, hyperemia of mucosa, and local inflammation when compared with inhaled corticosteroids alone (111501). It is unclear if these findings are due to black currant, other ingredients, or the combination.
• Seizures. Although there has been interest in using oral black currant leaf for seizures, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Upper respiratory tract infection (URTI). Although there has been interest in using oral black currant berry for URTIs, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Urinary tract infections (UTIs). Although there has been interest in using oral black currant leaf for UTIs, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Venous insufficiency. Although there has been interest in using oral black currant for venous insufficiency, there is insufficient reliable information about the clinical effects of black currant for this purpose.
• Wound healing. Although there has been interest in using topical black currant leaf for wound healing, there is insufficient reliable information about the clinical effects of black currant for this purpose. More evidence is needed to rate black currant for these uses.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.  Details Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects (1979,35995).

PHENOTHIAZINES Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.  Details Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures (88187). In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure (21013). In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures (21010).
