This trial is testing milk thistle, a plant known for its health benefits, to see if it can help adults with body dysmorphic disorder. The study involves 15 participants who will receive milk thistle over several weeks. Researchers hope that milk thistle's antioxidant and anti-inflammatory properties will improve symptoms of this condition. Milk thistle, derived from the species Silybum marianum, is traditionally used as a hepatoprotective agent.
