Licorice Root Candy: Is This Nostalgic Sweet Actually Good for You?
Whether you love the bold, earthy taste or recoil at the mention of it, licorice root candy has been a staple in confectionery jars for centuries. Derived from the root of the Glycyrrhiza glabra plant, this unique treat offers far more than just a hit of sweetness. Historically used as one of the world’s oldest herbal remedies, licorice has travelled from ancient Egyptian tombs to modern-day pharmacy shelves and sweet shops.
In this guide, we will explore the science behind licorice root candy, its potential health benefits, and the safety precautions you need to take before indulging in your next bag of black twists.
What Exactly is Licorice Root?
The term “licorice” literally translates to “sweet root” in Greek. The plant is native to Western Asia and Southern Europe, where it has been utilised for its medicinal properties for millennia. While many people associate the flavour with fennel seeds or star anise, true licorice comes from the extract of the legume plant’s root.
In the world of confectionery, not all “black licorice” is created equal. Many modern commercial sweets are flavoured with anise oil instead of actual licorice extract because it mimics the taste at a lower cost. However, authentic licorice root candy contains glycyrrhizin, the natural compound responsible for its signature sweetness and its pharmacological effects.
The Potential Health Benefits of Licorice Root Candy
When consumed in moderation, authentic licorice extract may offer several health perks. According to research published on NCBI, the bioactive compounds in the root have anti-inflammatory and antimicrobial properties.
1. Digestive Health and Heartburn Relief
Many people turn to licorice to soothe digestive health issues. It is often used to alleviate symptoms of acid reflux and indigestion. Some studies suggest that deglycyrrhizinated licorice (DGL)—a form of licorice with the glycyrrhizin removed—is particularly effective for long-term use without the side effects of standard extracts.

2. Sore Throat Relief
If you have ever reached for a licorice-flavoured lozenge during cold season, you have experienced sore throat relief first-hand. The root acts as an expectorant, helping to loosen mucus and soothe irritated membranes. The Mayo Clinic notes that various herbal teas and lozenges can provide temporary comfort for respiratory symptoms.
3. Skin Health
While we are focusing on licorice root candy, the extracts of this medicinal herb are also widely used in topical treatments to address eczema and acne due to their antibacterial qualities. For professional advice on skin conditions, visit the NHS website.
The Bittersweet Truth: Side Effects and Risks
Despite its benefits, licorice root candy carries significant risks if over-consumed. The primary culprit is glycyrrhizin, which can cause the body to lose potassium and retain sodium. This imbalance can lead to black licorice side effects such as oedema (swelling) and lethargy.
Impact on Blood Pressure
One of the most serious concerns is the link between excessive licorice intake and blood pressure. Consuming as little as 56g of black licorice a day for two weeks can lead to heart rhythm irregularities, especially in individuals over 40. The FDA has issued warnings regarding the consumption of traditional black licorice for this very reason.
Potassium Depletion
Low potassium levels (hypokalaemia) can impact heart health and muscle function. The American Heart Association emphasizes the importance of potassium in regulating the heart’s electrical activity. If you enjoy licorice frequently, it is vital to monitor your intake.

| Sugar-free sweets (Licorice) | Stevia or Xylitol, licorice extract | Suitable for diabetics | Potential laxative effect |
| DGL Supplements | Licorice extract (processed) | Safe for digestive issues | Lacks the “sweet” candy taste |
How to Enjoy Licorice Safely
You don’t have to give up your favourite licorice root candy entirely, but a mindful approach is best. Here are some tips for safe consumption:
- Check the label: Ensure the product actually contains licorice extract rather than just aniseed oil if you are looking for health benefits.
- Moderation is key: Stick to small portions and avoid daily consumption.
- Know your health status: If you have existing heart conditions or kidney disease, consult a doctor first. Detailed guidance on chronic conditions can be found at Gov.uk.
- Watch for sugar: Many candies are loaded with glucose. For those managing blood sugar, consider sugar-free sweets or check resources at Diabetes UK.
The Role of Licorice in Global Culture
Licorice isn’t just a British or American obsession. In Northern Europe, particularly in the Netherlands and Scandinavia, “salmiak” is a popular form of salty licorice flavoured with ammonium chloride. It provides a sharp, astringent taste that is an acquired preference for many. You can explore the diverse culinary uses of herbs on BBC Food.
The World Health Organization also recognises the use of licorice in various traditional medicine systems worldwide, highlighting its status as a globally significant medicinal herb.
The Bottom Line
Licorice root candy is a complex treat that sits at the intersection of confectionery and medicine. While it offers nostalgic joy and potential digestive support, it is a potent substance that requires respect. By choosing high-quality products and monitoring your intake, you can enjoy the unique flavour of the “sweet root” without compromising your health.

Frequently Asked Questions (FAQs)
Does red licorice have the same benefits as black licorice?
No. Most red “licorice” does not contain any licorice extract at all. It is typically a sugar-based candy flavoured with strawberry, cherry, or raspberry. Consequently, it does not provide the medicinal benefits or the risks associated with glycyrrhizin.
Can I eat licorice root candy while pregnant?
Medical experts generally advise against consuming large amounts of licorice during pregnancy, as high levels of glycyrrhizin may be linked to developmental issues. Always consult your midwife or GP. You can find more pregnancy safety advice on WebMD.
What is DGL and why is it safer?
Deglycyrrhizinated licorice (DGL) is licorice that has had the glycyrrhizin removed. This makes it much safer for long-term consumption because it does not affect blood pressure or potassium levels, while still providing the soothing properties needed for the stomach lining.
