Yerba Maté is a great alternative to coffee, soothing and re-energising
the body whilst providing nourishment with its magnificent properties

making it known as,

leaf “The liquid vegetable”

Yerba Maté has come to be recognised as one of the most beneficial natural beverages containing an incredible array of nutrients.  Yerba Maté has been researched for its properties for many years and in 1964, The Pasteur Institute and Paris Scientific society decided to conduct a study to see how many vitamins it possessed. The study concluded that, “It is difficult to find a plant in any area of the world equal to Maté in nutritional value”. In addition, they also stated that:

“It practically has all the nutritional value to sustain life"(2)

A study was completed by researchers at the University of Madrid which asserted a high content of mineral elements including K, Mg, and Mn, in Yerba maté. They considered those findings “to be of great relevance” to the nutritional value of Yerba maté infusions. It's also known to boost the Immune System as the yerba maté plant contains a number of powerful known saponins.

Zi Yerba Maté Pyramid


  • Nourishes & promotes Vitality
  • Boosts in Immune System Function
  • Increases and Sustains Energy Levels

  • Improved Mental Alertness, Focus and Clarity

  • Suppresses appetite and Enhances Weight Loss

  • Aids in resistance to Premature Aging through it's nutrients

Yerba Maté has been found to aid weight Loss, sustain energy levels and reduce fatigue as it stimulates the central nervous system. The metabolic effect of Yerba Maté suggest it has the ability to maintain the breakdown of carbohydrates during exercise for long periods of time due to it's nutrients and their effects on the human body. This means that more calories are burned as it increases cardiac effect and delays the build up of lactic acid. Physicians have been using Yerba Maté
(ilex- Paraguariensis - botanical name for Yerba Maté) as an ingredient for the treatment of obesity and it is used as a main ingredient in many natural weight loss pills, detox and diet supplements in chemists. Try having look?

A Swiss University studied various commercially-available plant preparations and have claimed that Yerba Maté extract possesses anti-obesity action. In 2000 a research team that studied obesity for gastric emptying and subsequent weight loss (Charlottenlund Medical Center in Denmark) tested a herbal preparation of Yerba Maté, Guarana, and Damiana (YGD)- From one of their studies it was concluded that the herbal preparation, YGD capsules, significantly delayed gastric emptying, reduced the time to perceived gastric fullness and induced significant weight loss in overweight patients within a 45 day period. The maintenance treatment given in an uncontrolled context resulted in no further weight loss, nor weight regain in the group as a whole.

Powerful Antioxidants?

We all know how important antioxidants are for our well being. As we get older, our cell membranes and other structures which include cellular proteins, lipids and DNA can become damaged. As oxygen is metabolised (oxidation) by the body it creates free radicals which are required in small amounts however can be harmful when our system becomes overloaded. The process of oxidation can be accelerated by stress, smoking, alcohol, sunlight and pollution. Research has shown that when these free radicals overload our system we are more susceptible to certain diseases, including heart and liver disease as well as some cancers. Antioxidants are naturally found in certain foods through Vitamins- A, C and E, Minerals- copper, zinc and selenium have all been known to neutralise these free radicals. Phytochemicals in plants are believed to have a higher antioxidant effect than vitamins A, C and E or the other minerals. It is for this reason Yerba Maté is believed to have a high antioxidant capacity containing many if not all of these antioxidant fighting properties! Phytochemicals contain recently discovered compounds that act as powerful antioxidants and are considered to exhibit anticancer effects in mammals by strengthening an organism’s natural defenses and protecting it against cellular destruction.

Polyphenal Graph

A group of researches from the University of the republica in Montevideo (Uruguay) did a study extracting Yerba mate and found it to be, “potent direct quenchers of the free radical 1,1- diphenyl-2-picrylthydrazyl.” Through this study they concluded that Yerba Mate is a, “rich source of polyphenols and has antioxidant properties comparable to those in green tea. Their study was published in the Journal of Alternative Complimentary Medicine in 2003 and their results showed the above. (5)

In 2007 a comprehensive study of Yerba Maté conducted found that it has 196 volatile chemical compounds, compared to the 144 contained in Green tea. (4)

In addition to polyphenols, yerba maté leaves contain saponins, one study yielded 3 new saponins in the Yerba Maté leaf. Saponins are phytochemicals that have been found to specifically stimulate the immune system and aid the body in protecting against disease. “Yerba Maté has been used since ancient times as a tea, is recommended throughout South America for it's rejuvenating, nutritional, and energetic effects, particularly for mental and physical fatigue. It can be taken as an effective weight loss aid and scientific research shows Maté to be a powerful antioxidant and that it can protect DNA from double- strand breaks”. (7) Polyphenols found in tea and yerba maté have been shown to prevent both the growth of bacteria responsible for bad breath and the bacteria’s production of odorous compounds.

Vitamins, minerals and their compounds are all found in the food we consume. Providing the body with adequate nutrients & antioxidants through our everyday diet and exercise can be challenging for many people especially in today’s busy and demanding environments. Heard of the saying, you are what you eat? Well if you’re not eating a well balance diet chances are that your skin, hair, eyes and overall physic will end up showing this! Exercise is also very important: “The Heart Foundation and other leading authorities recommend at least 30 minutes of moderate-intensity physical activity on all or most days of the week. This can be accumulated in bouts of ten minutes or more if this is more convenient.” (8)

We are also advised to eat at least 5 servings of fruit and vegetables a day. Are we all doing that? Research has also shown that there is little if any risk reduction with pill supplements that claim to contain antioxidants, furthermore researchers believe that the health benefits we get from antioxidants, are in fact due to the particular properties that exist in it's natural form. So vitamins and antioxidants that are naturally found in plants, fruit & vegetables prove to be more beneficial than supplementing these with pills.

Does Yerba Maté Contain Caffeine?

Yerba Maté does contain caffeine, each 2gm of My Great Maté tea bag contains approx. 0.01% caffeine.

Caffeine which can be found in many foods and beverages including coffee, teas, chocolate and Cola's, is a type of xanthine alkaloid that acts as a stimulant which posses the ability to enhance athletic and cognitive performance. Xanthines found in Yerba Maté include Theophylline, Theobromine and caffeine. Yerba Maté is a mild diuretic and reported to give people the stimulating properties and wake up the mind without the jittery or habituating side effects of coffee.  Yerba Maté has the ability to quicken the mind and increase mental alertness and acuity. Just as black tea and green tea contain caffeine so does Yerba Maté. The consistency varies according to how it is prepared, served, grown or manufactured although generally “The usual caffeine in Maté is 0.05% to 0.08% (compared to 1-2% in coffee)” (11)

Theobromine which can be found in Yerba Mate and dark chocolate has a similar stimulating effects to caffeine however is approximately 10 times weaker and is known to have a relaxing effect. Theophylline can be found in green and black tea and is also in small quantities in the Yerba Maté which is known to relax smooth muscle in the lungs airways. 

In fact, a study suggests that Yerba maté might be useful for treating a variety of disorders such as. . . “depression, disorders of attention and focus, mood and emotional disorders, Parkinson’s disease, extra pyramidal disorders, hypertension, substance abuse, eating disorders, withdrawal syndromes, and the cessation of smoking.” - 2002 US Patent, yerba maté for inhibiting monoamine oxidase (MAO) activity by 40-50% in vitro.
