It has some medicinal properties to it and has an fascinating history but it can be very perilous. The nickname “deadly nightshade” is a excellent clue of its potency. There is but a tincture that comes from this plant that is used for medicinal purposes. Belladonna is a perennial herb that is native to Europe and Asia Minor but is now grown quite often in the United States, Europe, and India. When the plant is in full bloom the plant is harvested and then dried for use.
