Liquorice has been a favourite treat and medicinal plant for centuries, known for its unique flavour and potential health benefits. Originating from the liquorice plant Glycyrrhiza glabra, it is commonly found in sweets and herbal remedies. Liquorice root extract is recognised for its antioxidant and anti-inflammatory properties, which can support digestive health and soothe sore throats.
Liquorice is cultivated by growing this perennial herbaceous plant, which can reach up to one meter in height. Its distinct flavour comes from glycyrrhizin, a compound significantly sweeter than sugar but which can cause health issues if consumed in large quantities. Liquorice is used in various forms, from traditional black sweets to supplements aimed at easing menopausal symptoms and promoting oral health.
Understanding the chemical composition and potential risks associated with liquorice is crucial. It can raise blood pressure and cause hormonal imbalances in some individuals. Despite these concerns, many people enjoy the benefits of liquorice responsibly, appreciating its role in both confections and natural medicine.

- Overconsumption may lead to health issues such as high blood pressure.
Origins and History
Liquorice has a rich history that dates back thousands of years. The root of the liquorice plant has been used for its sweet flavour and medicinal properties, spreading from native regions across Asia and southern Europe.
Liquorice Root and Ancient Tradition
The liquorice plant, known scientifically as Glycyrrhiza glabra, is native to southern Europe and parts of Asia. The Greeks referred to liquorice as “glykys” (sweet) “rhiza” (root). They used it for its healing properties and sweet taste.
Ancient civilisations, including the Egyptians, also prized liquorice root for its medicinal uses. It was found in the tomb of King Tutankhamun. In China, liquorice has been part of traditional medicine for centuries, valued highly for treating ailments.
The root contains glycyrrhizin, a compound much sweeter than sugar, explaining its use in sweets and medicines.
Spread Across Continents
Liquorice spread from its native regions through trade and cultural exchanges. The use of liquorice expanded across Europe during the Middle Ages. It became known in England thanks to the monasteries growing the plant for its therapeutic benefits.
During the 18th century, a pharmacist in England is said to have added sugar to liquorice root extract, turning medicinal syrup into a popular sweet. This led to the commercial production of liquorice sweets.
Today, liquorice is cultivated in many parts of the world and remains a beloved ingredient in confectionery. The town of Pontefract in England is famous for its liquorice cakes, known as Pontefract Cakes, emphasising the long-standing cultural significance of liquorice in the region.
Cultivation and Production
Liquorice is grown primarily for its roots, which are used in various products, including sweets and medicines. The key aspects of its cultivation involve selecting the appropriate growing conditions, harvesting the roots, and processing them for use.
Growing Conditions
Liquorice thrives in warm climates with ample sunlight. It prefers well-drained, fertile soil rich in organic matter. pH levels should be maintained between 6.0 and 7.5 for optimal growth. Seeds should be cold-treated in a fridge for 2-3 weeks, then soaked in hot water overnight to soften their coats before planting.
Spacing is crucial; plants should be spaced about 1 metre apart in rows to allow for the expansive root system. Regular watering is important, especially during dry spells, to prevent the roots from becoming desiccated. Mulching helps retain moisture and suppresses weed growth. Liquorice is a perennial and may take up to three years to mature fully, so patience is essential.
Harvesting and Processing
Roots are typically harvested in autumn when the plant is about three to four years old. Digging up the roots requires care to avoid damage. The roots are cleaned to remove soil and then dried in the sun or in a low-temperature oven. Dried roots can be stored for long periods if kept in a cool, dry place.
After drying, roots are often ground into powder or sliced for different applications. Fresh roots can also be used but have a shorter shelf life. The process of drying concentrates the juice in the roots, which is the primary component used in manufacturing.
Manufacturing Confectionery
Manufacturing liquorice sweets involves extracting the juice from the dried liquorice roots. This juice is boiled and concentrated to create a thick, syrupy substance. In confectionery production, various ingredients like sugar, starch, and flavourings are added. The mixture is then cooked and poured into moulds to set.
Once cooled, the liquorice is cut into desired shapes and sizes. Quality control is essential throughout this process to meet industry standards. This ensures that the final product is consistent in taste, texture, and appearance. Traditionally, liquorice sweets are black, but other colours and flavours can be achieved by adding different ingredients.
Chemical Composition
Liquorice, derived from the plant Glycyrrhiza glabra, contains a variety of chemical compounds and nutrients. These components contribute to its unique properties and uses in food, medicine, and other applications.
Active Compounds
The primary active compound in liquorice is glycyrrhizin, a sweet-tasting substance that is about 50 times sweeter than sugar. Glycyrrhizin is known for its anti-inflammatory and antiviral properties. It is often used in treating conditions such as ulcers and hepatitis.
Glycyrrhizinic acid is another significant component. It contributes to liquorice’s medicinal properties, particularly in soothing gastrointestinal problems. Flavonoids, present in liquorice, offer antioxidant benefits and protect cells from damage.
The chemistry of liquorice also includes saponins and polysaccharides. These compounds work together to provide the plant’s immune-boosting and detoxifying effects.
Nutritional Aspects
Liquorice contains minerals like potassium and sodium, which are essential for maintaining electrolyte balance in the body. Potassium levels are particularly important for heart function and muscle health.
In addition to minerals, liquorice is low in calories and has no significant fat content. This makes it a favourable option for health-conscious individuals.
While primarily known for its medicinal benefits, liquorice’s nutritional profile includes small amounts of vitamins and other minerals that contribute to overall health. Its unique combination of active compounds and nutrients makes it a valuable plant in both traditional and modern medicine.
Health Implications
Liquorice has both potential health benefits and risks. It contains compounds that can help with various conditions, but excessive consumption can lead to serious health problems.
Therapeutic Uses
Liquorice root has been studied for its benefits in treating several health issues. It contains glycyrrhizin, which has anti-inflammatory properties that can help alleviate conditions such as eczema and psoriasis.
Some studies suggest that liquorice can help with menopausal hot flushes. Women who took liquorice root extract reported reduced frequency and severity of their flushes.
Liquorice is also known to aid in treating digestive problems. For example, people with heartburn and indigestion saw improvements after taking liquorice root extract.
Moreover, it contains phytoestrogens, which can mimic oestrogen in the body and might be helpful in managing hormonal imbalances.
Adverse Effects
While liquorice can offer health benefits, it can also pose risks if consumed in large amounts. High blood pressure is one major concern. Excessive intake of glycyrrhizin can cause hypertension.
Liquorice can lower potassium levels in the body, leading to hypokalemia, which can cause muscle weakness and abnormal heart rhythms. In extreme cases, it can lead to edema or swelling due to fluid retention.
Medications like diuretics can magnify these effects. Therefore, it’s important for individuals, especially those with existing health issues, to be cautious about how much liquorice they consume. Regular consumption of liquorice sweets can contribute to these adverse effects.
