Summary
The goal of the proposed study is to evaluate the efficacy and safety of silymarin in individuals with gambling disorder. The hypothesis to be tested is that silymarin will be more effective and well tolerated in subjects with gambling disorder compared to placebo. The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.
