Licorice for Obesity: Does It Work?
Does Licorice (Yashtimadhu, Glycyrrhiza glabra) help with obesity? Honestly, only in a small supporting role. Ayurvedic tradition does name Licorice among the key herbs for obesity, but its own properties point the other way, and for most people with excess weight it is not the herb to start with.
The problem is its profile. Licorice is sweet and bitter in taste, cold in potency (Sheeta Virya) and sweet after digestion, and it calms Vata and Pitta while increasing Kapha (VP- K+). Most obesity (Medoroga, disease of the fat tissue) is Kapha-dominant, and the Charaka Samhita (Sutrasthana 21) lists excess sweet food among its classical causes.
Classical cautions are blunt: avoid Licorice with excess Kapha, swelling and high blood pressure, because it "increases water around the heart". Its active compound, glycyrrhizin, makes the body hold on to sodium and water, and watery weight gain and ankle swelling are among the warning signs of taking too much.
Where it can fit is as a minor ingredient. The Bhavaprakash Nighantu calls Licorice strengthening (Balya) and Pitta-calming (Pitta Shamaka), and it is traditionally used to harmonise herbal formulas. In small amounts, balanced by warming spices, it can soften a weight-loss formula for someone with Vata or Pitta signs. The real work is done by Kapha-reducing herbs such as Trikatu, Triphala and Guggulu.
How Licorice Helps with Obesity
Ayurveda traces obesity to weak digestive fire (Manda Agni). Undigested residue (Ama) deposits in the fat tissue (Meda Dhatu), Kapha accumulates, and the channels clog. The herbs that work best here kindle digestion, scrape fat and reduce Kapha. Licorice does none of these strongly, and it helps to understand why.
Why Licorice works against Kapha weight
Sweet taste, cold potency and a sweet post-digestive effect build tissue rather than deplete it. That is the opposite of the lightening therapy Ayurveda prescribes for obesity. Classical sources note that Licorice may aggravate Kapha if used long term, and its moist, heavy qualities can worsen swelling, congestion and sluggishness.
Modern pharmacology explains the water side. Glycyrrhizin makes the body behave as if aldosterone were raised, so it holds sodium and water and loses potassium. Blood pressure can rise, and the scales can go up with water rather than fat.
Where it can support
Not all obesity is Kapha-type. In the Pitta type, linked with acid reflux and inflammation, Licorice's cooling action on digestive heat is relevant, and DGL (licorice with the glycyrrhizin removed) is the form used for acid reflux. In the Vata type, it calms Vata and is traditionally given for debility and stress.
Its other traditional role is as a harmoniser: its taste masks harsher herbs and helps a formula sit well. Some practitioner sources also call it mildly laxative and say Licorice tea after meals aids digestion, though the Ashtanga Hridaya notes it lacks the purgative action of dried grapes.
What modern research says
Our sources contain no research on Licorice for weight loss. The well-documented modern findings concern its effects on blood pressure, potassium and cortisol, which are reasons for caution in obesity rather than reasons to use it.
How to Use Licorice for Obesity
If you use Licorice at all for obesity, use it small, short and balanced. It belongs as a minor part of a formula, not as the main herb. The best form depends on your pattern.
| Form | Dose | Use in a weight plan |
|---|---|---|
| Powder (Churna) | 250 to 500 mg in traditional practice; no more than 1 to 3 g a day, short term | With ginger or black pepper to offset its Kapha-increasing effect |
| DGL tablets | 380 to 760 mg, chewed | 15 to 20 minutes before meals, for Pitta-type weight gain with acid reflux |
| Tea | One cup | After meals; traditionally said to aid digestion and relieve constipation |
Balance it with warming spices
For anyone carrying excess Kapha, the standing advice is to combine Licorice with ginger or black pepper. Taking it with honey also helps, because honey's drying, scraping quality (Lekhana) balances Licorice's sweetness.
Skip the milk
Licorice is usually made safer by boiling it in milk. In a weight plan, though, a rich milk decoction adds the very heaviness you are trying to reduce, so powder with spices or DGL is the better fit.
Keep courses short
Limit internal use of whole Licorice to four to six weeks, then take a two-week break. Above about 3 g of powder a day, or daily use for months, the risk of raised blood pressure and potassium loss becomes real. Stop at once if you notice swollen ankles, a puffy face, headaches or sudden watery weight gain.
Who should not use it
Skip Licorice if your weight gain is the Kapha type with water retention, or if you have high blood pressure, heart or kidney disease, low potassium or are pregnant. For Kapha weight gain with sluggishness and sweet cravings, warming, drying herbs such as Trikatu are the right lead.
Frequently Asked Questions
Can Licorice cause weight gain?
It can cause watery weight gain. Glycyrrhizin makes the body retain sodium and water, and swollen ankles, a puffy face and sudden weight gain are signs of taking too much. These usually settle within one to two weeks of stopping. Classical texts also warn that its sweet, heavy nature increases Kapha.
Is Licorice safe if I have high blood pressure?
Not as whole root. High blood pressure is a classical and modern contraindication, and Licorice directly opposes blood pressure medication. It also adds to potassium loss with diuretics. DGL, which has the glycyrrhizin removed, carries essentially no blood pressure risk.
Can I take Licorice with diabetes medication?
Check with your doctor. Licorice can affect blood sugar in either direction and interacts with insulin and oral diabetes drugs. Because most diabetes linked to excess weight is Kapha-dominant, practitioners often prefer drying, bitter herbs instead.
What should I use instead of Licorice for weight loss?
For the common Kapha type, Ginger, Pippali and Black Pepper (together, Trikatu), plus Guggulu and Punarnava for water retention. For Pitta-type weight gain, Kutki and Garcinia. For stress-driven Vata-type weight gain, Ashwagandha and Shilajit.
Recommended: Start Licorice for Obesity
If you are considering Licorice for obesity, here is the honest starting point: for most people it should be a small helper, not the lead herb.
Best form: a small amount of Licorice powder inside a warming formula. Its sweet, cooling, Kapha-increasing nature needs balancing, and in a formula its role is to soften and harmonise.
Kitchen version: mix 250 to 500 mg of Licorice powder with a pinch of ginger or black pepper and a little honey. Keep it to a few weeks at a time.
Dosha fork: if your weight gain is the hot Pitta type with acid reflux, chewable DGL before meals is the safer choice. If it is the heavy Kapha type with water retention, skip Licorice and start with Trikatu instead.

Safety & Precautions
Licorice is one of the most-used herbs on earth, but it is also one of the very few Ayurvedic herbs with a well-documented, dose-dependent side-effect profile. The active compound glycyrrhizin is the reason for both its power and its cautions. The good news: nearly all of the risk is avoidable by understanding dose and form.
The Hypertension Warning (Read This First)
Glycyrrhizin inhibits the enzyme 11-beta-hydroxysteroid dehydrogenase, which allows cortisol to act on mineralocorticoid receptors. The practical result is pseudoaldosteronism, the body behaves as if aldosterone is elevated. This means:
- Sodium and water retention, blood pressure rises
- Potassium loss through urine, risk of hypokalaemia
- In extreme cases: muscle weakness, arrhythmia, and oedema
Classical Ayurveda describes this directly: Licorice "increases water around the heart" and is contraindicated in hridroga (heart disease) and swelling. Modern cardiology agrees. Do not take therapeutic doses of whole-root Licorice if you have high blood pressure, congestive heart failure, kidney disease, low potassium, or a history of stroke. For any of these, DGL is the safe alternative.
Dose Matters Enormously
The difference between "daily tonic" and "adverse event" is dose and duration:
- Culinary/trace amounts (a piece of root in tea, a lozenge), safe for virtually everyone
- 1-3 g/day of powder, short-term (up to 4-6 weeks), safe for most healthy adults
- Above 3 g/day, or daily for months, real risk of BP elevation and potassium loss, even in previously healthy people
- DGL, no glycyrrhizin, effectively no BP risk at any typical dose
Drug Interactions
Licorice can meaningfully interact with several common medications. If you are on any of the following, consult your doctor before using therapeutic doses:
- Diuretics (especially thiazides and loop diuretics), compounds potassium loss dangerously
- Digoxin, low potassium increases digoxin toxicity risk
- Corticosteroids, Licorice extends their half-life and effect
- Warfarin, may alter bleeding risk
- Blood pressure medication, Licorice directly opposes the drug's action
- Oral contraceptives and hormone therapy, phyto-oestrogenic effect may potentiate
- Insulin and oral hypoglycaemics, Licorice can affect blood sugar in either direction
Pregnancy and Nursing
Classical Ayurveda states plainly: do not use in pregnancy. Modern observational data aligns, high Licorice intake during pregnancy is associated with preterm labour and second-trimester bleeding risk. Small culinary amounts and DGL are likely fine, but therapeutic whole-root use should be avoided. During breastfeeding, small amounts appear safe, but avoid prolonged high-dose use.
Other Cautions
- High Kapha individuals, Licorice's sweet, heavy, moist qualities can aggravate Kapha and worsen oedema, congestion, or sluggishness. Combine with ginger or black pepper to offset.
- Low potassium diet, Licorice increases potassium excretion. Pair with potassium-rich foods (banana, spinach, coconut water).
- Calcium absorption, chronic high-dose use may interfere with calcium absorption; classical texts flag caution in osteoporosis.
- Hypoglycaemia, Licorice can lower blood sugar; take with food if prone.
Signs You Are Taking Too Much
Watery weight gain, puffy face, ankle swelling, muscle weakness or cramps, headaches, and unexplained BP elevation. If any of these appear, stop immediately, effects usually resolve within 1-2 weeks once the herb is discontinued.
