This research substantiates the traditional use of Glycyrrhiza uralensis Fisch. for liver health, with scientific evidence of the non-toxic and lipid-lowering properties of licorice sprout extracts. The sprouts' rich mineral and amino acid content, along with their strong antioxidant activity, reinforce their value in traditional medicine. These findings bridge ancient herbal practices with modern science, highlighting licorice's potential in contemporary therapeutic applications.

The study aimed to investigate the dietary and medicinal potential of G. uralensis sprouts by assessing their safety, nutritional content, and antioxidant properties using both plant and animal models. Specifically, the study sought to determine the effects of different sizes of licorice sprouts on lipid metabolism in human liver cancer cells and their overall impact on rat health indicators.

The study examined the effects of aqueous and organic extracts from G. uralensis sprouts of varying lengths on the cytotoxicity, lipid metabolism, and antioxidant activity in HepG2 cells, alongside in vivo impacts on Sprague-Dawley rats, using MTT, ICP, and HPLC. It aimed to assess the potential health benefits of licorice sprouts by analyzing their protective effects against oxidative stress and their nutritional content.

Licorice sprout extracts from G. uralensis demonstrated no cytotoxicity in HepG2 cells, significantly reduced lipid levels, and enhanced antioxidant activities, with the longest sprouts (7 cm) showing higher mineral, sugar, and arginine content as well as increased glycyrrhizin and liquiritigenin. In vivo studies with Sprague-Dawley rats revealed weight gain and improved antioxidant enzyme activities in blood plasma and liver tissues after consuming the extracts, highlighting the sprouts' dietary and therapeutic potential.

This study is the first to demonstrate that G. uralensis sprouts, particularly those 7 cm in length, have no cytotoxic effects, reduce lipids, and have high mineral and antioxidant contents, offering promising dietary and therapeutic benefits.
