Licorice for Headaches: Does It Work?

Does Licorice (Yashtimadhu) help with headaches? It has a place, but as a supporting herb rather than a headache remedy on its own. Ayurvedic guidance on headache and migraine lists Licorice among its key herbs, alongside Brahmi, Ginger, Bala and Fennel. It is most relevant when the headache follows a Vata or Pitta pattern.

The reasoning comes from its profile. Licorice is sweet and bitter in taste, cooling in potency, and it calms Vata and Pitta while it can increase Kapha. The Bhavaprakasha classes it as Pitta-pacifying (Pitta Shamaka), anti-inflammatory (Shothahara) and intellect-promoting (Medhya), and Ayurvedic references describe it as mentally calming and nourishing to the brain.

It also has a classical link to the head. The Charaka Samhita, Chikitsa Sthana, Chapter 26 (Trimarmiya Chikitsa), which deals with disorders of the head and other vital organs, includes Licorice in head preparations, among them an oil cooked with Bhringaraj juice and a Licorice paste.

One caution shapes everything else on this page: whole licorice root can raise blood pressure, and high blood pressure is itself one of the recognised causes of headache.

How Licorice Helps with Headaches

Ayurveda sorts headaches by which dosha reaches the head. Vata headaches sit at the back of the head and travel with anxiety, stress, dryness and constipation. Pitta headaches sit at the temples and travel with acid indigestion, hyperacidity and overheating. Licorice speaks to both.

For the Pitta pattern

Licorice's cooling potency (Sheeta Virya) and sweet-bitter taste counter heat, and the Bhavaprakasha lists it as Pitta Shamaka. Its best-known digestive use is for acidity, gastritis and ulcers, where it soothes and coats inflamed mucous membranes. Since the Pitta headache is described as being related to the stomach and intestines, calming that acid heat at its source is the logic for including Licorice.

For the Vata pattern

Licorice pacifies Vata. It is demulcent (moistening and soothing), relieves muscle spasms, and is described as sedative and mentally calming. It is also a mild laxative, and licorice tea after meals is used to aid digestion and relieve constipation. That matters because constipation is one of the classic drivers of Vata headaches, pushing Vata upward into the head.

Where it does not fit

Licorice can aggravate Kapha with long use, and edema and excess Kapha are listed as precautions. For the heavy, congested Kapha sinus headache, warming, drying herbs such as ginger are the classical match instead.

How to Use Licorice for Headaches

For headaches, the most useful form is a milk decoction (Ksheerapaka), licorice simmered in milk. Traditional sources note that Licorice's precautions are reduced when it is taken in boiled milk, and milk adds its own calming, Vata- and Pitta-soothing effect. Taking it in milk this way is an example of anupana, the vehicle that carries an herb.

FormDoseBest forWhen
Milk decoction (Ksheerapaka)100 to 150 mlVata or Pitta headache with stress and poor sleepMorning or bedtime, warm
Powder (Churna)1 to 3 gPitta headache tied to acidityWith warm water, up to twice daily
Licorice tea1 teaspoon or less of powder per cupVata headache tied to constipation or sluggish digestionAfter meals

Keep it short and modest

Around 3 grams of powder a day is the practical ceiling for whole-root licorice in healthy adults. At 1 to 3 grams a day, use it for short courses of up to 4 to 6 weeks, then pause. Above that dose, or daily for months, the risk of raised blood pressure and potassium loss becomes real.

Combine with the core headache measures

Licorice works best alongside the main dosha-specific remedies. For Vata, that means warm oil on the scalp and feet and steady routines; for Pitta, cooling measures such as a sandalwood paste on the temples and a cooled cumin-coriander tea.

Frequently Asked Questions

Is Licorice safe if my headaches come with high blood pressure?

No, not as whole root. Glycyrrhizin in licorice causes sodium and water retention and raises blood pressure, and Ayurvedic texts list hypertension as a precaution. High blood pressure is also one of the listed causes of headache, so whole licorice could make the underlying problem worse. DGL (deglycyrrhizinated licorice) removes this risk but is mainly a digestive form.

Can I take Licorice with my medications?

Check with your doctor first if you take diuretics, digoxin, corticosteroids, warfarin, blood pressure medication, hormone therapy, or diabetes medication. Licorice interacts with each of these. Do not use therapeutic doses during pregnancy.

How long can I take Licorice for headaches?

Use it in short courses. At 1 to 3 grams of powder a day, up to 4 to 6 weeks is considered safe for most healthy adults. Long, continuous use is where the blood pressure and potassium problems appear.

Licorice or Brahmi for headaches?

For most people, Brahmi is the stronger lead herb: it is the classic nervine for stress-driven Vata headaches, and Brahmi for headaches covers it in detail. Licorice is more of a soothing partner. For Pitta headaches, Fennel is listed among the purgatives that reduce Pitta causes of migraine, and for Kapha sinus headaches Ginger is the better fit.

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.
