in general it's best to discuss with your the herbs supplements extracts cleanses and any other substances you regularly ingest because many of them do indeed interact with medications like crestor (atorvastatin). i'm not familiar with garcinia mangostana in particular but your safest option is not to take it unless your health care provider or pharmacist has told you it's ok. wishing you well!
is garcinia mangostana safe to take with crestor?
