Licorice – natural support for cough and digestive issues
Author: Petra Pertl

There’s that kind of cough that just won’t go away. Or the stomach discomfort that keeps coming back again and again. In such cases, many people focus only on symptomatic solutions, yet there are medicinal herbs that support the body from multiple angles at once. Licorice is one of them — and it’s no coincidence that it has long been used for both respiratory and digestive problems.

What is licorice?

Licorice (Glycyrrhiza glabra) is a perennial plant whose root is used for medicinal purposes. Its characteristic sweet taste comes from glycyrrhizin.

Main active compounds:

  • glycyrrhizin
  • flavonoids
  • triterpene saponins

Together, these give licorice its versatile effects.

How does it work?

Licorice acts on multiple levels in the body.

Mucosal protection:
It stimulates mucus production, which coats and protects mucous membranes — both in the stomach and the respiratory tract.

Reduced pepsin activity:
In the stomach, it can reduce pepsin activity, helping to decrease irritation of the mucosal lining.

Anti-inflammatory effect:
Flavonoids and saponins help reduce inflammatory processes.

Expectorant effect:
It helps loosen and clear mucus from the airways.

Respiratory issues – when the cough won’t go away

One of the best-known uses of licorice is for respiratory conditions.

It may help with:

  • dry cough
  • productive cough
  • throat irritation
  • colds

It both soothes irritated mucous membranes and supports mucus clearance.

Application

It is most commonly used as a decoction or syrup.

Support for gastric and duodenal ulcers

Another important area of use for licorice is the stomach.

It may be used for:

  • gastric ulcers
  • duodenal ulcers
  • stomach irritation

By increasing mucus production, it coats the stomach lining and helps protect it from acidic conditions.

Digestive complaints

Licorice can also be helpful beyond ulcers.

It may support:

  • heartburn
  • sensitive stomach
  • excess stomach acid

These effects are mainly based on mucosal protection and reducing inflammation.

How to use it

Licorice can be used in several forms:

Decoction:

  • place 1 teaspoon of chopped root in cold water
  • boil for 5–10 minutes
  • strain before use

Tincture:

  • a concentrated extract used in smaller amounts

Preparations:

  • capsules
  • syrups
  • combined herbal products

Safety considerations

Licorice requires careful use.

Possible side effects:

  • sodium and water retention
  • potassium loss
  • edema
  • high blood pressure

Not recommended in cases of:

  • hypertension
  • heart or kidney disease
  • pregnancy
  • long-term, continuous use

Licorice is a versatile medicinal herb that supports both the respiratory and digestive systems. Thanks to its expectorant, anti-inflammatory, and mucosal-protective effects, it can be especially useful for cough and stomach complaints.

If you’re looking for a solution that doesn’t just target one symptom but supports the body more broadly, licorice can be a good choice — when used with proper care.
