Introduction to Plant Raw Materials
The raw material of this product is the dried root and rhizome of the leguminous plant Glycyrrhiza uralensis Fisch. Mainly produced in Xinjiang, Inner Mongolia, and Gansu. It is sweet in taste and neutral in nature, entering the heart, lung, spleen, and stomach meridians. It has the effects of tonifying the spleen and replenishing qi, clearing heat and detoxifying, resolving phlegm and relieving cough, easing urgency and stopping pain, and harmonizing various medicines.
Core Effects
The following summary of licorice effects is based on published scientific research and traditional applications. Specific effects should be comprehensively evaluated according to the Licorice extract product form and dosage used.
Licorice (Glycyrrhiza uralensis) extract has been widely studied for liver health and anti-inflammatory effects. Its key component glycyrrhizic acid is metabolized in the body to glycyrrhetinic acid, which exerts anti-inflammatory effects by inhibiting NF-κB and AP-1 transcription factor activity (Journal of Pharmacological Sciences, 2006). Glabridin (commonly 0.1%-1%) is a natural tyrosinase inhibitor of significant research interest, with an IC50 of 0.3 μg/mL and in vitro activity higher than hydroquinone (Journal of Investigative Dermatology, 2003), making it widely applied in cosmetic brightening. Glycyrrhizic acid can also inhibit angiotensin-converting enzyme (ACE), providing a research basis for blood pressure health.
Regulatory and Regional Market Status
The following Licorice extract information is compiled from publicly available regulations; actual market access should follow the latest regulations of the target country.
| Region/Country | Regulatory Status | Key Notes |
| United States (FDA) | Dietary Supplement / GRAS | Generally regulated as dietary supplements if they are plant extracts; some ingredients have been GRAS recognized (specific confirmation needed on a case-by-case basis). USP has included monographs for various extracts. |
