What is Licorice?

Licorice is a root belonging to the Glycyrrhiza glabra family, which is used as a flavoring agent in parts of Europe and Asia. This sweet and aromatic root is also utilized for flavoring tobacco and confections like taffy. It has long been used in herbalism and traditional medicine in different parts of the world, and is still used for some medicinal purposes.

  • In the past, the dried root was sold as a sweet in itself, though that has largely been replaced by licorice-flavored confections.
  • With a pungent odor that is similar to camphor and a flavor that encompasses extreme sweetness with some bitterness, licorice is often an acquired taste.

Origin of licorice

The earliest evidence of use is from China around 2300 BC, when Emperor Shennong had the root recorded as a magic plant that rejuvenated old men. The root was also popular in ancient India, ancient Egypt, and Assyria.  Licorice root was found in Tutankhamun’s tomb dating back to 1350 BC. It was used extensively in Ayurvedic medicine in India, as well. 

The name itself is derived from two Greek words combining ‘sweet’ and ‘root’, and the root was used extensively as a medicine in ancient Greece and Rome. By the Renaissance period, this food was commonly used to flavor sponge cakes and an array of sweets. Today, the popularity of the root has decreased, though it remains widespread in certain areas.


This has been traditionally used for thousands of years as a medicine in different cultures. The root has a wide range of health promoting properties, such as antibacterial, anti‐inflammatory, antiviral, antioxidant, and antidiabetic activities. It is a rich source of proteins, amino acids, polysaccharides, flavonoids, and carbohydrates. Also, it contains calcium, phosphorus, sodium, potassium, iron, magnesium, silicon, selenium, manganese, zinc, and copper. The sweet taste of this food is due to the glycyrrhizin, a triterpenoid saponin that is 50 times sweeter than sucrose. 

One cup of bite sized licorice (182g) contains:

However, consumption of licorice on a daily basis may lead to health conditions, such as hyperaldosteronism, hypokalemia, and muscle weakness. Creatine phosphokinase (CPK) may be elevated in cases with rhabdomyolysis, which may be complicated with acute tubular necrosis. This food may also cause high blood pressure, plasma renin, and aldosterone levels, as well as a reduction in the conversion of cortisol to cortisone. Therefore, it’s recommended to consume this food in moderation. 

Commercial production

Many licorice products sold in the US may actually not contain the root. Instead, anise oil, which has a similar taste and odor, is used. The world’s main producers of this food are India, Iran, Italy, Afghanistan, the People’s Republic of China, Pakistan, Iraq, Azerbaijan, Uzbekistan, Turkmenistan, and Turkey.
