1. Antioxidant, its antioxidant ability is far higher than VC, VE and Teapolyphenols, and 2 to 4 time stronger than BHA and BHT. It is stable andendures high temperature of 190-240C.

2. Prevents senescence, eliminates free radicals.

3. Antisepsis, antibioticand anti-inflammatory.

4. Skincare - skinrestoring and moisturizing, eliminates freckles.

5. Reducesserum totalcholesterol and fatty tissue: not only effectively decreases serumcholesterollevels, but also reduces the cholesterol content in differenttissues such asliver, heart and fatty tissue

[Mechanism of Antioxidant]

Carnosic acid is the starting element of a unique antioxidant mechanism called the “Carnosic Acid Cascade” (See below figure). The cascade is an exceptional series of chemical reactions that involve the transformation of carnosic acid into carnosol; carnosol into rosmanol; and rosmanol into galdosol. With each of these transformations, free radicals are quenched.

1. Ursolic acid presented a potent antihyperglycemic effect, increased insulin vesicle translocation, insulin secretion and augmented glycogen content. Also, Ursolic acid stimulates the glucose uptake through the involvement of the classical insulin signaling related to the GLUT4 translocation to the plasma membrane as well as the GLUT4 synthesis.

2. Endogenous Takeda G-protein-coupled receptor 5 (TGR5), G-protein-coupled bile acid receptor 1 (GPBAR1), regulates glucose metabolism. In animals, TGR5 activation by a chemical agonist may increase incretin secretion and reduce the blood sugar level.Ursolic acid can activate TGR5, enhancing GLP-1 secretion in vitro and in vivo.

3. Anticancer.
