RAD is an increasingly common disorder associated with problems in distinguishing reality from fantasy. Evidence suggests that herbal remedies may be as effective as standard drug therapies in treating RAD symptoms. This study will determine the safety and efficacy of an herbal treatment in adults with RAD.

This study will last 9 weeks. Participants will be randomly assigned to receive either an herbal product or placebo three times a day for the duration of the study. Participants will participate in a test of their ability to distinguish fantasy from reality and their RAD symptoms and any side effects will be assessed by self-report rating scales.
