Black currant (Ribes nigrum) is sometimes used as a complementary approach to support patients undergoing chemotherapy, primarily to help reduce side effects such as oxidative stress, inflammation, and immune suppression. The scientific rationale centers on black currant’s high content of anthocyanins and other polyphenols, which are known for their potent antioxidant and anti-inflammatory properties. A handful of preclinical studies have demonstrated that black currant extracts can reduce markers of oxidative damage and inflammation in cell cultures and animal models exposed to chemotherapeutic agents. For example, some studies have observed protective effects on liver and kidney tissues, as well as evidence for improved antioxidant enzyme activity and reduced lipid peroxidation when black currant extract is administered alongside chemotherapy drugs.

However, evidence in humans is limited. A few small clinical studies and pilot trials have explored the use of black currant juice or extract in cancer patients, suggesting possible improvements in markers of oxidative stress or subjective symptoms like fatigue, but results are preliminary and sample sizes are small. There is not yet robust clinical data to confirm efficacy, and black currant is not an established evidence-based treatment for chemotherapy side effects. Its use is best considered as a potentially supportive measure with a favorable safety profile rather than a proven intervention. More rigorous human studies are needed to confirm benefits. Patients should consult their healthcare provider before using black currant supplements during chemotherapy.
