Licorice against viruses

We have known coronaviruses for a long time. In 2003, it was proved that a substance called glycyrrhizin contained in licorice, works better antivirally than synthetic drugs from pharmacies. The study was published in the most important scientific journal The Lancet.

The antiviral potential of ribavirin, 6-azauridine, pyrazofurin, mycophenolic acid and glycyrrhizin has been studied. Glycyrrhizin was found to be the most active in inhibiting SARS-inducing coronavirus replication (severe acute respiratory distress syndrome).

Glycyrrhizin has high virus selectivity. In addition to inhibiting replication, Glycyrrhizin inhibits the absorption and penetration of the virus into cells. The mechanism of action is not entirely known, but it is known to include effects on cell signaling pathways and the stimulation of nitric oxide synthase and its production by macrophages.

Licorice against viruses and microbes

Licorice root is a powerful antiviral agent. Its main component, glycyrrhizin, works against a wide range of microorganisms. It inhibits the ability of enveloped viruses to bind to host cells. Works effectively on enveloped viruses, among others

- coronaviruses
- poxviruses
- herpesviruses
- togaviruses
- retroviruses

Nitric oxide inhibits the replication of various viruses. Glycyrrhizin should be used for a short time, with long-term use side effects such as hypertension and reduced blood potassium may occur, we recommend that you familiarize yourself with the side effects before using licorice root

Liquorice will not save us from disease. But it will cause that when we get sick, Glycyrrhizin will inhibit the penetration of viruses through cell membranes.

- Licorice root has a very sweet taste, similar to anise, with a bitter-salty taste. The longer the root stays in the water, the more intense it gives the flavor, so it should not be brewed for too long.
- It is best to prepare the brew from licorice root. Just pour boiling water over it and brew for about 5 minutes - it's worth adjusting the amount of liquorice and brewing time to your taste preferences.
- A pinch of cut licorice root is worth adding to tea to give it an interesting, sweet taste. Licorice goes well with herbal, spice and ginger teas. It doesn't go well with fruit teas and lemon juice. Licorice root can also be chewed.
The dried root should be stored in a tightly closed container. You can store it for a very long time.
- Licorice raises blood pressure, so it should not be used by people with hypertension!
- People suffering from heart disease, diabetes, kidney disease, liver disease and hypokalemia should not take licorice.
- It is better not to eat licorice in the evening, because it can interfere with falling asleep.
- Licorice should not be used for a long time. After 4 weeks of use, take a break.
- Excessive licorice intake can cause side effects such as elevated aldosterone levels, headaches, fatigue, high blood pressure, and water retention.

Interesting herbal tea.

I came across this herb under its Latin name on a supplement from Spain and am pleased to be able to find a supplier of the actual herb in UK.

Very Informative and Interesting Product

Everything arrived on time and in an informative manner and presentation.

Lovely tea

Nice change if you like any type of green tea. Good fresh, rounded, bright flavour with a slight aniseed/ fennel taste in my opinion which adds another dimension.
