A parent, who has been diagnosed with PD, has a friend in Germany who states that something called "Bulgarian Wild Cherry" helps ease discomforts experience by people who have PD. Several homeopathic books that I have do not have any references to the medicine and an archive search turned up empty. Does anyone have information on "Bulgarian Wild Cherry" ? Or something close to that term. Perhaps the translation from German to the English language was not accurate. Thank you for your time.
