Terva Leijona is a Finnish liquorice candy with tar flavouring. The candy is produced by the Leaf Candy Company.
It is available in "Traditional flavours" such as sugarless, licorice, salmiakki. Recently Leaf released Villi Pohjola (Wild North) mix that contains some of more exotic flavours, such as juniper berry - lemon, cloudberry - licorice and lingonberry - havu (pine/spruce needles).
The company's original product "Lakritsi" has an unusual or unpleasant taste to some people hence the reason for the company to introduce more exotic flavours.
