What did thwaites say liquorice was made out of?

Thwaites stated that liquorice is made from the root of the Glycyrrhiza glabra plant, which contains a compound called glycyrrhizin. This natural sweetener is what gives liquorice its distinctive flavor. Additionally, the production of liquorice involves extracting the juice from the root, which is then processed and often combined with other ingredients to create various confections.
