Liquorice

Also called Glycyrrhiza glabra this plant is sweet tasting and produces seeds. Ever since ancient Greece, the liquorice plant has been used as a medicine to treat heart conditions and asthma, while Roman soldiers chewed on liquorice roots in their marches over wet cold terrains. It's part of a Fabaceae family genus that thrives in warm climates. The Greek physician, Dioscorides, shaped the meaning and name of the plant we know. It's also named "sweet grass". Besides medicine, liquorice has been used in tobacco and candies. It can be poisonous in very large amounts.
