Liquorice – a respiratory tonic

This root is one of the most extensively investigated botanical remedies. It has been shown in well conducted studies to heal peptic ulcers, aid menstrual irregularities, act as an anti-inflammatory.

There is some evidence that liquorice in small amounts can be used to decrease sugar cravings. However it is most widely used as an expectorant and decongestant.

The majority of these effects are due to its glycyrrhizinic acid component. However other components also play a major role in its pharmacological action.

While people with peptic ulcers are often given deglycyrrizinated liquorice which has been shown to be equally effective without the side effects, though, for a variety of reasons, many herbalists steer clear of the chemically altered liquorice products.


Recommended three-times-daily dosages are usually: 1-4 grams of the powdered root, 1-6 mls (1 ½ teaspoons) of the fluid extract or 250-500 mg of the solid extract.

Take care

Liquorice can cause potassium loss, sodium retention and high blood pressure in some people. It should not be taken by those with high blood pressure, kidney failure or those on heart medicines such as digoxin.
