Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Surgery: California poppy can slow down the central nervous system, causing sleepiness and other effects. There is some concern that California poppy might slow down the central nervous system too much when combined with anesthesia and other medications used during and after surgery. Stop using California poppy at least 2 weeks before a scheduled surgery.
