Health properties of Yerba Mate.

Introduction: Yerba Mate, also called Paraguay tea, is obtained from the dried leaves (approximately 95%) and stems (about 5%) of the evergreen shrub-tree Ilex paraguariensis. Each year, the consumption of yerba mate becomes increasingly popular in North America and Europe. The fashion for Paraguay tea has also reached Poland. During the period 2012 - 2018, as much as an 8-fold increase has been observed in the import of this raw material to our country.

Objective: The aim of the study is analysis of the present state of knowledge concerning the health effects of Yerba Mate, based on selected scientific literature.

Dicussion: The consumption of yerba mate may exert a beneficial effect on human health and its consumption is recommended in the treatment of obesity and while practicing sports. Nevertheless, it should be remembered that a very high consumption of the tea, especially when very hot, may increase the risk of occurrence of cancer, which has not been unequivocally confirmed by scientific studies to-date.

Conclusions: It has been confirmed that this beverage shows a number of beneficial health effects, including: a protective effect on liver cells, stimulation of the central nervous system, anti-inflammatory effect, as well as a positive effect on the cardiovascular system.
