Each tube is enough for 8 fl oz of cream or lotion at approximately 2% concentration (5 g in 240 mL cream). Use in your favorite cream or add to our Canvas Base Cream.
The fine white powder will not dissolve completely, but will release components slowly into the cream or lotion. This special licorice extract is a white powder and will not change the color of the cream.
Licorice root has been used in Europe since prehistoric times, documented since the ancient Greeks, for its anti-inflammatory and antimicrobial activity. Phyto Chemists and biochemists have been working for decades to clarify the structure of the chemicals involved and the mechanisms of action. In the case of the root of Glycyrrhiza glabra, there is not a single chemical that benefits the skin, but rather a combination of many chemicals. Glyzyrhizinic acid, a chemical found in licorice root, has been shown to have pro-interferon and antiviral activity.*
