In the U.S. currant often means Zante currants, or dried Cornith grapes that are really just small raisins. Fresh red or black currants (pictured right) aren't widely available, but worth seeking out if they're grown near you.
You can eat the berry of the black currant plant. The berry is also used as a flavoring in liqueurs and other products. The juice, leaves, and flowers of black currant are safe when eaten in food products. Black currant is also considered safe if you use the berry or seed oil appropriately as medicine.
