What is Glycyrrhiza pallidiflora? It is a wild licorice plant, and the root is the part people have used. It grows in East Asia, including parts of China, Korea and the Russian Far East.
It is one of roughly twenty licorice species. Almost all licorice research comes from two others: Glycyrrhiza glabra and Glycyrrhiza uralensis. What is known about those plants does not automatically carry over to this one.
Here is the honest verdict on evidence. There are no human trials of this species for any health use. Its traditional record is local and thin.
Long use by a tradition is not proof that a plant works. It is also not proof that a plant is safe. Both points matter here, because this is a licorice, and licorice roots can raise blood pressure.
If you buy a product labelled only "licorice", you usually cannot tell which species is inside. Treat an unnamed licorice root as you would treat common licorice.
How is it thought to work? No mechanism has been shown for this species in people. What follows comes from licorice chemistry and from laboratory work, not from trials.
Licorice roots can contain glycyrrhizin, a sweet saponin. In people, glycyrrhizin blocks an enzyme in the kidney that breaks down cortisol.
That can hold salt and water in the body, push blood pressure up, and drop potassium. This effect is well documented for licorice in general.
How much glycyrrhizin this species holds is not settled. Some chemical reports find low levels. Testing is sparse, and wild plants vary.
Licorice roots also carry flavonoids. In cell and test-tube studies, some licorice flavonoids appear to calm inflammation signals and slow certain bacteria. Whether anything like that happens in a person who drinks a tea is not established.
So the fair summary is simple. The risk side of licorice chemistry is proven in humans. The benefit side, for this species, is not.
How is it sold? Honestly, it is seldom sold under its own name. Most licorice on shelves is Glycyrrhiza glabra or Glycyrrhiza uralensis.
Where this species is used, the usual forms are:
- Dried, sliced or chopped root, simmered as a decoction (a long-boiled tea). - Powdered root, loose or in capsules.
- Alcohol tinctures or liquid extracts. - A minor ingredient in mixed herbal formulas.
You may also meet it in botanical gardens or seed catalogues as an ornamental or forage plant. No product of this species has a recognised standard strength. Labels that simply say "licorice root" should be treated as common licorice.
What did tradition claim? Records for this species alone are sparse. It was gathered in parts of East Asia and the Russian Far East, often as a local stand-in for common licorice when that was scarce.
Folk use reported for wild licorice roots in those regions included soothing coughs and sore throats, settling the stomach, and sweetening bitter herbal mixtures. Classical Chinese and Japanese medical texts name Glycyrrhiza uralensis and Glycyrrhiza glabra, not this plant.
The plant has also been studied as a forage and soil-binding species rather than a medicine. None of this history tested the plant against a placebo. It is background, not evidence, and it is not a reason to start taking it.
Stop taking it and speak to a doctor if you notice swollen ankles, hands or face, headaches, or unusual muscle weakness or cramps.
Also stop and get checked if your blood pressure readings climb, or if you feel short of breath doing things you normally manage.
Seek emergency care now if you have chest pain, a pounding or irregular heartbeat, fainting, or weakness so severe you cannot stand. These can signal dangerously low potassium.
In the United States, United Kingdom and European Union, licorice root is sold as a food or food supplement, not as a licensed medicine. This species is almost never named on a label. European food safety advice flags regular glycyrrhizin intake above about 100 mg a day as a concern.
