Stevia vs liquorice root

The two sweet botanicals, and both carry a distinctive tail that ordinary sugar does not. One is a Paraguayan leaf and the other a Eurasian root, and they sweeten very differently.

What is being compared

Point by point

AspectSteviaLiquorice root
The part usedThe dried leaf, which is intensely sweet on its own.The dried and often peeled root, sliced or shredded.
SweetnessVery sweet with a green, slightly bitter tail the refined extract removes.Sweet with a distinct anise-adjacent flavour that is impossible to hide.
TraditionGuaraní use to sweeten yerba mate, documented by European botanists in the 1880s.Used across the Middle East, China and Europe for millennia, in drinks and confectionery.
PreparationSteeped with the other material, one leaf at a time.Simmered — it is a root, and steeping gets far less out of it.
Modern formMet almost entirely as a refined white powder in soft drinks rather than as a leaf.Still traded as root, and also as an extract for confectionery.

The short answer

For sweetening without adding flavour, neither works — both bring their own. Stevia is the cleaner of the two if used in tiny quantity; liquorice is a flavour decision as much as a sweetening one.
