We also know that it improves psychomotor performance without the typical xanthine-induced depressant after effects. Jose Martin, Director of the National Institute of Technology in Paraguay, writes, "New research and better technology have shown that while Mateine has a chemical constituency similar to caffeine, the molecular binding is different.Mateine has none of the ill effects of caffeine." And Horacio Conesa, professor at the University of Buenos Aires Medical School, states, "There is not a single medical contraindication" for ingesting Mate.If that is not enough for you, here are just a few of the documented health benefits of Yerba-Mate Tea. The tea was introduced to colonizing and modern civilizations by the primitive Guarani Indians of Paraguay and Argentina and has seemingly always been the most common ingredient in household cures of the Guarani.In modern Argentina and Paraguay, however, Mate tea has become almost pathologically ritualized in a manner reminiscent of coffee and tea abuse in Western and Eastern countries.Although the xanthines have similar chemistries, each has a unique set of properties.Researchers at the Free Hygienic Institute of Hamburg, Germany, concluded that even if there were caffeine in Mate, the amount would be so tiny that it would take 100 tea bags of Mate in a 6-ounce cup of water to equal the caffeine in a 6-ounce serving of regular coffee.Some xanthines are obviously less desirable, such as caffeine.Others, such as theophylline and theobromine, have specialized action and a characteristic set of side effects.
Though only small amounts of these substances occur in Mate, their presence has generated a huge amount of attention.
Improvement in mood, especially in cases of depression, often follows.
Mate does not interfere with sleep cycles; in fact, it has a tendency to balance the cycles, inducing more rapid eye movement (REM) sleep when necessary, or increasing the amount of time spent in delta states (deep sleep).
Mate appears to work mainly by softening the fecal mass, but it also appears to stimulate normal movement of the intestines to some degree.
Better than any other xanthine alkaloid, Mate has the ability to increase mental alertness and acuity and to do it without any side effects such as nervousness and jitters.
The primary xanthine in Yerba-Mate is called Mateine.
