Licorice for Hot Flashes & Night Sweats: Does It Work?
Does Licorice (Yashtimadhu, "sweet stick") help with hot flashes and night sweats? Yes, in short courses during the hardest stretches. It is one of the cooling herbs Ayurveda uses to reduce how often flashes come, but it is not a long-term daily tonic.
Ayurveda reads a hot flash as heat released and carried outward. The heat is Pitta, the dosha of fire and metabolism, which surges as the hormonal cycle withdraws. Vata, the dosha of movement and dryness, rises at the same time and delivers that heat in sudden waves.
Licorice speaks to both. It is sweet and bitter in taste and cold in potency (Sheeta Virya), and it calms Vata and Pitta while it can increase Kapha. The Bhavaprakash Nighantu lists it as Pitta-calming (Pitta Shamaka) and anti-inflammatory (Shothahara).
Its cooling reputation runs through the classical texts. The Ashtanga Hridaya (Sutrasthana, Chapter 22) names Licorice alongside sandalwood and lotus among the substances for summer gargles, the season when Pitta heat runs highest.
The catch is safety. With extended use Licorice raises blood pressure, so courses are capped at six to eight weeks, with Shatavari as the ongoing base.
How Licorice Helps with Hot Flashes & Night Sweats
Licorice works on hot flashes and night sweats through three actions: cooling, moistening and a mild hormonal effect. Each one matches part of the Pitta and Vata picture.
Cooling the heat
In the Pitta pattern, years of heat held in the plasma (Rasa Dhatu) and blood (Rakta Dhatu) surge as estrogen fluctuates and stops buffering it. The result is intense, frequent flashes, drenching night sweats, flushed skin and irritability.
Its cold potency and sweet taste are the classical answer to that heat. Sweet is one of the three Pitta-reducing tastes, and the condition texts place Licorice among the cooling herbs used to reduce hot flash frequency.
Soothing dry membranes
As Vata rises, it dries tissue: skin, eyes and the vaginal lining. Licorice is a demulcent, meaning it coats and soothes mucous membranes, so it eases the dryness that often comes between flashes.
That moistening, sweet quality is also why it is avoided where Kapha already leads, with heaviness and fluid retention.
Mild phytoestrogenic and adrenal support
Modern research describes hot flashes as a nervous-system event: a narrowed thermostat in the hypothalamus that fires when estrogen levels swing. Licorice contains isoflavones, such as glabridin, that bind estrogen receptors weakly and selectively, the same category of action as the saponins in Shatavari.
It also supports the adrenals. Its main compound, glycyrrhizin, slows the breakdown of cortisol in the kidneys. That same effect is the source of its limit: with continued use it leads to sodium retention, potassium loss and a rise in blood pressure, which is why courses stay short.
How to Use Licorice for Hot Flashes & Night Sweats
For hot flashes and night sweats, use Licorice as a short course during a bad stretch, then stop. Keep a long-term cooling herb such as Shatavari running underneath it.
| Form | Dose | Best For | Course |
|---|---|---|---|
| Licorice powder (Yashtimadhu Churna) | 1 to 3 g twice daily | Frequent flashes, dry membranes | 6 to 8 weeks maximum |
| Licorice tea | 1 tsp root simmered in about 200 ml water for 5 minutes | Milder daily use during a symptomatic phase | Within the same 8-week limit |
A safe daily ceiling for whole-root preparations in most healthy adults is around 3 g of powder. Beyond that, the blood-pressure effect becomes real.
What to take it with
The traditional vehicle (Anupana) is warm water or honey. Stir honey in only once the water is no longer hot.
For the Pitta pattern of flashes, pair the course with cooling, sweet foods and cut back on spicy, sour and fermented ones, alcohol and coffee. If dryness rides along with the heat, combine it with Shatavari and nightly external sesame oil (Vata) or coconut oil (Pitta).
How long to expect
Run a course of up to 8 weeks, then pause for a similar or longer period before another. Monitor your blood pressure during the course.
If a consistent herbal and lifestyle approach has not helped in 8 to 12 weeks, talk to your doctor about other options, including hormone therapy.
Who should not take it
Do not use Licorice with high blood pressure, kidney disease, low potassium or corticosteroids, or during pregnancy. Skip it if heaviness, puffiness and water retention (the Kapha pattern) lead.
Frequently Asked Questions
Why can I only take Licorice for 8 weeks?
With continued daily use, its glycyrrhizin causes sodium retention, potassium loss and a gradual rise in blood pressure. This is a documented effect, not a theoretical one. Six to eight weeks is the maximum course, and you should monitor your blood pressure while you take it.
When is Licorice the right herb for my hot flashes?
When you are in an acute phase: intense flashes that are new or have recently worsened, especially with dryness and irritability. It is a short-course intensifier, not a baseline. For chronic, low-grade flashes, start with Shatavari and reserve Licorice for flares.
Can I take Licorice if I have high blood pressure?
No. Hypertension is a firm contraindication for whole-root Licorice, and the same applies to kidney disease, heart failure, diuretics and corticosteroids. A cooling alternative without that risk is Amla, or Guduchi where the heat comes with sluggish digestion.
Licorice or Shatavari for hot flashes?
Usually both, in different roles. Shatavari is the long-term base for every pattern and is safe for ongoing use. Licorice is the short-term addition for a bad stretch, then it stops while Shatavari continues.
Recommended: Start Licorice for Hot Flashes & Night Sweats
If you want to start using Licorice for hot flashes and night sweats today, here is the simplest starting point: 1 to 3 g of Licorice powder twice daily with warm water, for no more than 8 weeks. Powder lets you control the dose, which matters with a herb you take in courses.
Kitchen version: simmer a teaspoon of Licorice root in a cup of water for five minutes, strain, and let it cool a little before stirring in a teaspoon of honey.
Fork by pattern. If heat leads (Pitta: intense flashes, drenching night sweats, irritability), take it with water and keep spicy food, alcohol and coffee low. If dryness leads (Vata), keep Shatavari in warm milk at night alongside the course. If heaviness and fluid retention lead (Kapha), skip Licorice.

Safety: do not take Licorice with high blood pressure, kidney disease, corticosteroids or during pregnancy, and stop by 8 weeks.
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.
