Okay, let's talk about that polarizing candy sitting in grandma's candy dish. You know the one - those dark, chewy sticks that smell like medicine and taste like... well, an acquired taste. I remember sneaking pieces as a kid during holidays, loving that intense flavor while my cousins spat it out dramatically. But beyond childhood nostalgia, what's the real deal? Is black licorice actually good for you? We're going beyond the hype to break down everything you need to know.
First things first - real black licorice contains glycyrrhizin from licorice root, not just artificial flavoring. That's what gives it that distinctive punch. My Dutch friend swears by it for sore throats, while my doctor warned me about eating too much during pregnancy. Confusing signals, right? Let's sort facts from folklore.
What's Actually in Black Licorice?
Not all licorice is created equal. See, what most Americans call "red licorice" isn't licorice at all - it's just strawberry candy. True black licorice gets its muscle from Glycyrrhiza glabra root. One brand I buy lists licorice extract as the second ingredient after molasses. That extract contains the bioactive compound glycyrrhizin, which is 50 times sweeter than sugar but brings baggage.
Here's what you're biting into with a typical 40g serving of black licorice:
Nutrient | Amount | Daily Value % |
---|---|---|
Calories | 140 | 7% |
Sugars | 24g | 48% |
Fiber | 1g | 4% |
Glycyrrhizin | 200-800mg | Not established |
Sodium | 65mg | 3% |
That sugar load matters. But the real player is glycyrrhizin—the chemical causing all the fuss when people wonder is black licorice good for you. This compound messes with your cortisol metabolism, which explains both its traditional uses and modern health warnings.
Potential Benefits: Where Licorice Shines
Okay, let's talk upsides before the scary stuff. Traditional medicine uses licorice root for centuries:
Sore throat relief: My personal go-to during winter. Glycyrrhizin forms a protective coating over irritated membranes. Many cough drops actually contain licorice extract for this reason.
Digestive help: Research suggests compounds in licorice may reduce Helicobacter pylori bacteria linked to ulcers. A 2013 study had participants taking licorice extract showing symptom improvement.
Skin conditions: Topical licorice gel shows promise for eczema according to dermatology journals. The anti-inflammatory effects calm redness and itching.
But here's the caveat—most studies use concentrated extracts, not candy. That bag of licorice twists won't deliver medicinal benefits without delivering problematic doses of glycyrrhizin first. Which brings us to...
The Dark Side of Too Much Licorice
Remember that man hospitalized after eating a bag daily for weeks? True story reported in the New England Journal of Medicine. He developed dangerously low potassium and cardiac arrhythmia.
Glycyrrhizin causes pseudoaldosteronism—a fancy term meaning it tricks your kidneys into retaining sodium while dumping potassium. Symptoms sneak up:
- Swollen ankles (I noticed this after my licorice-heavy movie marathon)
- Muscle weakness that makes climbing stairs exhausting
- Headaches and high blood pressure
- In severe cases, irregular heart rhythms
How much triggers trouble? Health agencies sound alarms around glycyrrhizin intake:
Group | Maximum Daily Glycyrrhizin | Equivalent Black Licorice |
---|---|---|
Healthy Adults | 100mg | 2oz (57g) |
Hypertension Patients | Avoid | Zero |
Pregnant Women | Avoid | Zero |
Over 40 | 50mg | 1oz (28g) |
Seriously, pregnant folks should steer clear. Glycyrrhizin crosses the placenta and may impact fetal development. My OB-GYN practically banned me from licorice during both pregnancies.
Licorice Face-Off: Candy vs. Supplements
Now things get tricky. When evaluating is black licorice good for you, we must distinguish candy from therapeutic products:
Product Type | Glycyrrhizin Content | Purpose | Safety Profile |
---|---|---|---|
Candy (e.g., Twizzlers Black) | Medium (200-400mg/100g) | Recreational | ⚠️ Risk at >57g/day |
DGL Supplements (deglycyrrhizinated) | None | Ulcer/Heartburn relief | ✅ Generally safe |
Licorice Root Tea | High (varies) | Traditional medicine | ⚠️ Limit to 1 cup daily |
Topical Creams | Low absorption | Skin conditions | ✅ Low risk |
DGL (deglycyrrhizinated licorice) supplements remove the problematic compound. I take these occasionally for heartburn—works better than Tums without the chalky aftertaste. But your average candy aisle licorice? Different beast entirely.
Who Should Absolutely Avoid Black Licorice?
Some people need to treat licorice like poison ivy:
- Hypertension patients: Glycyrrhizin can spike BP. My uncle learned this after his reading jumped 20 points post-licorice binge.
- Heart disease patients: Potassium loss destabilizes heart rhythms. Not worth the risk.
- Kidney disease sufferers: Impaired kidneys struggle with electrolyte imbalance. Just don't.
- Pregnant women: Linked to preterm labor and developmental issues. Stick to prenatal vitamins.
- People on diuretics or steroids: Dangerous interactions. Check your med labels!
Navigating Licorice Labels Like a Pro
Here's where manufacturers get sneaky. "Licorice flavor" might mean artificial compounds with zero glycyrrhizin - safer but lacking any benefits. "Licorice extract" means real deal with risks.
Spot-checking popular products:
Brand | Licorice Source | Glycyrrhizin (per 100g) | Glycyrrhizin (per piece) |
---|---|---|---|
Panda Black Licorice | Licorice extract | ~600mg | 120mg per 20g piece |
Twizzlers Black | Artificial flavor | None detected | 0mg |
Dutch Dropjes | Licorice extract | ~800mg | 80mg per 10g drop |
Yogi Licorice Tea | Licorice root | ~300mg per tea bag | 300mg per serving |
See the trap? Two pieces of Panda licorice put you over the recommended daily limit. Meanwhile, Twizzlers are basically sugary wax with flavoring—no glycyrrhizin, but no benefits either. Personally, I avoid both extremes and opt for high-cocoa dark chocolate instead.
When Medicinal Use Makes Sense
Licorice root has legitimate uses under professional guidance:
Adrenal fatigue: Some functional medicine docs prescribe short-term licorice to support cortisol production. My naturopath gave me a 2-week protocol after burnout.
Respiratory support: Glycyrrhizin demonstrates antiviral activity in lab studies. Used in some traditional COVID protocols (though not FDA-approved).
Topical applications: That licorice-based brightening serum in my cabinet? Contains glabridin shown to inhibit melanin production safely.
Your Licorice Safety Cheat Sheet
Practical rules for enjoying licorice without ending up in the ER:
- Check labels for "licorice extract" vs. "artificial flavor"
- Limit real licorice candy to under 2oz (57g) per day
- Never consume daily for >4 weeks consecutively
- Balance with potassium-rich foods (avocados, bananas)
- Watch for swelling, headaches, fatigue
- When in doubt, choose DGL supplements instead

Licorice FAQ: Your Questions Answered
How long does it take for black licorice to affect blood pressure?
In sensitive individuals, BP can rise within 1-2 weeks of daily consumption. One study showed average 14mmHg systolic increase after 14 days of 100g/day licorice.
Can black licorice cause permanent damage?
Chronic overconsumption can potentially cause lasting hypertension or heart damage. A 2020 case study documented persistent arrhythmia even after discontinuation. Moderation is non-negotiable.
Does boiling licorice root destroy glycyrrhizin?
No - glycyrrhizin remains stable at boiling temperatures. Tea made from licorice root contains concentrated amounts. My herbalist recommends steeping no longer than 5 minutes and limiting to one cup daily.
Why do Scandinavians eat so much salty licorice safely?
They've developed higher tolerance through lifelong exposure, but health warnings still apply. Finnish health authorities report licorice-related ER visits annually. Their "salmiakki" often contains ammonium chloride too - a double whammy.
Can pets eat black licorice?
Absolutely not! Glycyrrhizin is toxic to dogs and cats. Even small amounts can cause muscle tremors or worse. My neighbor's poodle got into licorice and needed IV fluids. Keep it locked away.
The Final Verdict on Licorice
So after all this, what's the bottom line when asking is black licorice good for you? It's complicated:
- Traditional medicine value: ✅ Yes, when used correctly
- Candy as health food: ❌ No, absolutely not
- Occasional treat: ️ Maybe, in tiny amounts
That intense flavor I loved as a kid? Still enjoy it maybe twice a year. But I measure portions carefully now. For daily antioxidants, I grab berries instead. Your body will thank you.
Licorice isn't evil - it's a powerful plant that demands respect. Understand your personal risk factors, read labels religiously, and never assume more is better. When in doubt, consult your doctor. Mine still teases me about that licorice intervention.
