(NaturalNews) The herbal supplement milk thistle may prevent liver damage in people undergoing chemotherapy, according to a new study conducted by researchers from Columbia University Medical Center and published in the journal Cancer.

Researchers conducted the study on 50 children undergoing a "maintenance" round of chemotherapy for acute lymphoblastic leukemia (ALL), a type of blood cancer. Approximately two-thirds of all children undergoing treatment for ALL usually develop liver toxicity during their treatment, presenting doctors with the choice between scaling back the treatment and risking a resurgence of the cancer, or continuing with treatment unaltered and risking permanent liver damage and lifelong health complications. There is currently no known way of preventing liver toxicity in chemotherapy patients.
