TeraSerum™ Yerba Mate is a microencapsulated botanical extract for the delivery of natural polyphenols. It is extracted with water and encapsulated to powder with maltodextrin (modified starch). Highly concentrated in antioxidant plant phytochemicals (chlorogenic acid, caffeic acid, rutin, caffeine, oleanolic acid).
TeraSerum Yerba Mate is soluble in water with mixing. We recommend adding directly to the water phase, below 40oC, to preserve the natural characteristics.
“Yerba Mate is a powerful adaptogen – it’s an herb that grows in extreme conditions but adapts and thrives in harsh environments.As a result, adaptogens contain high levels of antioxidants and saponins that defend the plant against disease and make them resistant to insects and environmental damage.These potent antioxidant properties help protect against free radical damage and slow down the ageing process.”
The anti-oxidant potential of TeraSerum Yerba Mate was evaluated in-vitro using reconstructed human epidermis (RHE). Reactive Oxygen Species (ROS) were measured following UVA light-induced oxidative stress on samples treated with various concentrations of active vs. control.
RHE tissues were cultured in the presence of TeraSerum Yerba Mate at 0.1% and 1% for 24 hours and subsequently subjected to UVA light (15 J/cm2, 30 min exposure). The fluorescence of the ROS-oxidized product of H2DCFDA, 2’,7’-dichlorofluorescein (DCF) was recorded and relative ROS levels were corrected versus cell viability (measured by the reduction of resazurin to resorufin) to assess the protective effect of the tested sample.
A sharp and statistically significant decrease in ROS levels by 63.1% and 73.2% vs. control was achieved for 0.1% and 1% TeraSerum Yerba Mate treated samples, respectively.
