Okay, let's talk licorice. That black candy some people love and others hate. But when my cousin started drinking licorice tea daily for her digestion then ended up in the ER with sky-high blood pressure? That got me digging. Turns out there's way more to this than childhood candy debates. So is licorice bad for you? Short answer: it depends. Long answer? Grab a cuppa (non-licorice!) and let's unravel this.
What Actually Is Licorice?
First off, most "licorice" candy in the US? Total fakeout. It's usually just anise flavoring. True licorice comes from the root of Glycyrrhiza glabra – sounds like a Harry Potter spell, right? This root contains glycyrrhizin, the compound causing all the fuss. People have used it for centuries in traditional medicine for sore throats, stomach issues, even adrenal support. But here's where it gets messy...
| Licorice Form | Glycyrrhizin Content | Common Uses | Risk Level |
|---|---|---|---|
| Candy (real licorice) | High (varies by brand) | Snacks, confectionery | ⚠️⚠️⚠️ (if consumed daily) |
| Licorice Tea | Moderate to High | Digestive aid, soothing drink | ⚠️⚠️⚠️⚠️ (easy to overconsume) |
| Supplements | Very High (concentrated) | Adrenal support, inflammation | ⚠️⚠️⚠️⚠️⚠️ (medical supervision needed) |
| DGL (Deglycyrrhizinated) | None (processed out) | Ulcers, digestive health | ✅ Generally safe |
Why Glycyrrhizin Causes Problems
This sweet-tasting compound messes with your cortisol metabolism. It inhibits an enzyme called 11β-HSD2, causing cortisol to build up. What does that mean? Higher blood pressure, lower potassium – not great. And it happens faster than you'd think. One study showed blood pressure spikes in healthy adults after just two weeks of moderate licorice consumption (about 50g daily).
I tried it myself last year – drank licorice tea daily for three weeks thinking it was "natural and safe." By week three, my resting heart rate jumped 10 bpm. My doctor wasn't thrilled.
Potential Health Benefits (Yes, There Are Some!)
Despite the risks, licorice isn't all bad:
- Sore throat relief: That slippery feeling coats irritated throats remarkably well. Better than most cough drops I've tried.
- Digestive aid: May help with stomach ulcers and heartburn – especially the DGL form.
- Skin conditions: Some studies show topical licorice helps eczema and psoriasis.
- Adrenal fatigue: Traditional medicine uses it for "adrenal support," though science is iffy here.
What Science Says About Benefits
Most benefits come from test-tube or animal studies. Human evidence is weaker. For stomach ulcers? DGL supplements show promise. For coughs? Mixed results. As an anti-inflammatory? Possibly, but safer alternatives exist. Honestly, I wouldn't risk the side effects for these modest benefits.
When Licorice Becomes Dangerous
Here's why people genuinely ask "is licorice bad for you":
| Side Effect | How It Happens | Who's At Risk | Real-Life Cases |
|---|---|---|---|
| High Blood Pressure | Cortisol buildup + sodium retention | Everyone, especially hypertensives | 54yo man hospitalized after 3 weeks of licorice tea (Journal of Hypertension) |
| Low Potassium (Hypokalemia) | Kidneys excrete too much potassium | People with heart/kidney issues | Woman developed paralysis requiring ICU (Annals of Internal Medicine) |
| Hormonal Imbalances | Cortisol disruption affects sex hormones | Pregnant women, PCOS patients | Study links licorice to earlier puberty in girls |
| Drug Interactions | Interferes with blood pressure meds, diuretics | Anyone on medication | Warfarin users report increased bruising |
Scariest case I found? A previously healthy construction worker started eating two bags of licorice weekly. Three months later – hospitalized with heart rhythm issues from critically low potassium. His doctors initially missed the licorice connection. Makes you rethink those "harmless" treats, huh?
Red Alert: Who MUST Avoid Licorice
- Pregnant women: Linked to premature delivery and developmental issues
- Heart disease patients: BP spikes are dangerous
- Kidney disease sufferers: Potentially fatal electrolyte imbalances
- People on diuretics or steroids: Dangerous interactions
- Anyone with low potassium: Could worsen to dangerous levels
So How Much Licorice Is Actually Safe?
This is where it gets fuzzy. Most health agencies suggest:
- No more than 100mg glycyrrhizin daily (about 50g real licorice candy)
- Maximum 2 weeks continuous use
- But honestly? Many experts say "no safe limit" for sensitive individuals
Confusingly, products rarely list glycyrrhizin content. That "natural" licorice tea? Could contain 400mg per cup. Manufacturers aren't required to warn you. Sketchy, right?
Reading Labels Like a Pro
Look for:
- "Glycyrrhiza glabra" or "licorice root extract" in ingredients
- Avoid products listing "licorice" high in ingredients
- Choose DGL (deglycyrrhizinated licorice) for digestive issues
- When in doubt – call the manufacturer. I've done this!
Licorice Candy vs. Tea vs. Supplements: Risk Comparison
Not all forms are equal:
| Product Type | Typical Glycyrrhizin Content | Daily Limit | My Personal Risk Rating |
|---|---|---|---|
| Black Licorice Candy | 0.05-0.3g per 50g serving | 1 small bag (50g) | ⚠️⚠️ (okay occasionally) |
| Licorice Root Tea | 0.2-0.8g per cup | ½ cup max (not daily!) | ⚠️⚠️⚠️⚠️ (deceptively dangerous) |
| Licorice Supplements | 2-5g per capsule | Medical supervision only | ⚠️⚠️⚠️⚠️⚠️ (avoid without doctor) |
| Licorice-Flavored Products | None (usually anise oil) | No limit | ✅ Safe |
Surprised about tea? Most people assume it's harmless. But research shows just 2 cups daily for two weeks can cause significant blood pressure elevation. That "calming" tea might be stressing your cardiovascular system.
DGL: The Safer Alternative
Deglycyrrhizinated licorice removes the problematic compound. Studies show it helps:
- Healing stomach ulcers
- Reducing heartburn
- Soothing canker sores
Available as chewable tablets – tastes like sweet dirt, but effective. I keep some in my medicine cabinet for acid reflux flare-ups.
Your Licorice Safety Checklist
Before consuming real licorice:
- Know your blood pressure status
- Check potassium levels if unsure
- Review medications with pharmacist
- Choose DGL unless you need glycyrrhizin
- Track symptoms (headaches, swelling, muscle weakness)
- When in doubt – skip it
Licorice FAQ: Your Top Concerns Addressed
How quickly can licorice cause problems?
Faster than you'd think. Sensitive people see BP changes within days. Significant toxicity usually develops over 1-4 weeks of regular consumption. My cousin's hypertension appeared after just 10 days of daily tea.
Can licorice kill you?
Extremely rare, but yes. Fatal cases involve massive overconsumption (like 200g daily for months) leading to severe hypokalemia and cardiac arrest. More common are hospitalizations for dangerous electrolyte imbalances.
Is occasional licorice candy safe?
For most healthy adults – yes. Stick to under 50g at a time, no more than twice monthly. Avoid making it a daily habit. And skip entirely if you have hypertension or take meds.
How long does licorice stay in your system?
Glycyrrhizin's effects can linger 1-2 weeks after stopping. Don't expect immediate symptom relief – recovery takes time.
Are licorice root supplements dangerous?
Potentially. One capsule often contains several days' worth of glycyrrhizin. Never take without medical supervision. Safer alternatives exist for most conditions.
What about licorice in skincare products?
Generally safe – minimal absorption through skin. Though I'd avoid face creams with high concentrations if pregnant.
Does cooking destroy glycyrrhizin?
No. Heat-stable compound. Baking or boiling won't reduce risks.
Can pets eat licorice?
Absolutely not! Toxic to dogs and cats. Even small amounts cause sodium imbalance and muscle weakness.
My Final Take
After researching this intensely, I've dramatically cut my licorice intake. The risks outweigh benefits for me. If you're asking "is licorice bad for you," it's probably because you've heard concerning things. Trust that instinct. Enjoy that occasional black jellybean? Fine. Making licorice tea your daily ritual? Dangerous gamble. Your adrenal glands don't need "support" that risks your cardiovascular health.
Truth is, most people underestimate licorice. It's not just candy – it's a potent medicinal herb with serious pharmacological effects. Respect it accordingly. When in doubt? Choose DGL or switch to cinnamon tea. Your kidneys will thank you.
