The Core Ingredient: The Glycyrrhiza Glabra Root
The foundation of all true liquorice, and the single ingredient in pure liquorice sticks, is the root of the Glycyrrhiza glabra plant. This perennial herb is native to the Mediterranean region and Western Asia. Its roots are where the magic happens, containing the natural compound glycyrrhizin. This compound is responsible for the distinctively sweet and slightly bitter flavor, and it is incredibly potent—up to 50 times sweeter than regular sugar.
The Journey from Root to Pure Stick
The production of natural liquorice root sticks is a straightforward process focused on preservation.
- Harvesting: The roots are typically harvested in the autumn after the plant has matured for several years, usually two to three.
- Processing: The harvested roots are cleaned to remove dirt and impurities, then dried.
- Finishing: The dried roots are cut to a uniform length to be sold as chewable sticks, ready for consumption. These sticks are often firm and dark brown, with a woody, fibrous texture.
The Candy Confection: A Different Recipe
While pure root sticks offer an authentic, intense flavor, the popular liquorice candy sticks found in stores are a multi-ingredient confection. These products use an extract derived from the liquorice root as a primary flavor, but they rely on several other components to create the desired sweetness, texture, and consistency.
Ingredients for Commercial Liquorice Candy
The exact recipe can vary by brand and region, but most commercial liquorice candy includes a standard set of ingredients to achieve its chewy texture and sweet taste:
- Liquorice Extract: The concentrated flavoring boiled down from the Glycyrrhiza glabra root.
- Sweeteners: Sugar, glucose syrup, or treacle are added to enhance sweetness.
- Binders: Wheat flour is a common ingredient, acting as a binder to give the candy its structure. Starch, like potato or corn, can also be used,.
- Glazing Agents: Ingredients like gum arabic provide a smoother texture.
- Flavorings: Aniseed oil is frequently added to amplify the liquorice flavor, especially in many American versions, where it may even completely replace real liquorice extract,.
- Coloring: Ingredients like caramel are used to achieve the signature dark color.
The Manufacturing Process for Candy
Creating commercial liquorice candy is a more complex, multi-stage process:
- Extraction: The liquorice roots are boiled to create a syrupy extract.
- Mixing & Cooking: The extract is combined with the other ingredients in large kettles and heated to a high temperature to form a pliable dough,.
- Shaping: The mixture is extruded or molded into the familiar stick shapes.
- Cooling & Drying: The newly formed candy sticks are cooled and allowed to set.
- Finishing: A glossy finish is often applied using a coating agent in a tumbling drum.

|---|---|---|
| Primary Ingredient | Dried Glycyrrhiza glabra root | Liquorice extract, wheat flour, sugars | 
| Flavor Source | Natural glycyrrhizin from the root | Glycyrrhizin, plus added sweeteners and flavorings (like aniseed oil) | 
| Texture | Woody, fibrous, chewable | Soft and chewy or hard and brittle, depending on the recipe |

The Use and History of Real Liquorice Sticks
The history of liquorice is deeply rooted in its medicinal properties, with its use documented for over 3500 years. Ancient civilizations, including the Egyptians and Greeks, used the root to treat a variety of ailments. Today, pure liquorice sticks can still be used for their historical purposes.
Common uses for pure liquorice sticks:
- Chewing: Sucking on and chewing the stick releases the sweet, earthy flavor.
- Infusions: Steeping pieces of the root in hot water creates a soothing herbal tea.
- Cooking: The flavor can be infused into sauces, syrups, and desserts.
- Nicotine Cravings: For some, chewing a liquorice stick can help curb nicotine cravings.
Potential Health Considerations
While natural liquorice has potential benefits like aiding digestion and soothing respiratory issues, excessive consumption of glycyrrhizin can be problematic. High intake can lead to side effects such as elevated blood pressure, low potassium levels, and irregular heartbeats. Many health authorities recommend limiting intake or choosing deglycyrrhizinated liquorice (DGL) products if you have health concerns or consume it regularly.

Conclusion: Clarifying the Liquorice Stick
Ultimately, the composition of a liquorice stick depends entirely on the product in question. A pure, natural stick is simply the cleaned and dried root of the Glycyrrhiza glabra plant, containing only its inherent compounds. On the other hand, a commercial liquorice stick is a complex food product, often comprising an array of ingredients like flour, sweeteners, and flavorings. Understanding this fundamental difference is key to appreciating the true origin of this classic flavor and deciding which form best suits your taste or health needs.
