Anti-Cancer Properties

Anti-Cancer Properties

You've heard that green tea's antioxidants have been shown to help prevent cancer.  With antioxidant levels far higher in traditionally consumed yerba mate, researchers have found yerba mate to contain many anti-cancer properties.  Here is a short summary of the yerba mate research:

  • Has large amounts of cancer fighting antioxidants & polyphenols, 
  • Appears to inhibit and destroy both tumors and different types of cancer
  • Mitigates inflammatory diseases
  • Appears to have anti-cancer effects from more than just the polyphenols

Yerba Mate Polycyclic Aromatic Hydrocarbons (PAHs)

PAHs are common in a bunch of foods and beverages, such as coffee, tea, water, meats, and other foods. They are impossible to avoid, yet they are known to be carcinogenic in higher concentrations.  Heavily smoked yerba mate's contain higher levels of PAHs than brands not heavily smoked.  For this reason, one would be wise to avoid any roasted yerba mate, which we do not sell.  Still, non-smoked yerba mate's have been shown to have 80% less PAHs than some more heavily smoked methods.  We are proud to offer a variety of non-smoked brands, for those wishing to reduce PAHs in their diet.  Check out our low PAH Unsmoked Kraus Yerba Mate and Unsmoked EcoTeas Yerba Mate brands. 

Avoid Scolding Temperatures when Drinking Yerba Mate

The practice of Traditional Medicine, according to Subhuti Dharmananda, Ph.D., Director of the Institute for Traditional Medicine in Portland, Oregon notes that it does not reccommend drinking any teas at excessively hot temperatures (2005). There are studies that identify a connection between throat damage caused by any extremely hot liquids, which can then lead to an increased risk of cancer. Consumption of any drinks (coffee, tea, hot water) or soups at very high temperatures has been reported as a risk factor for esophageal cancer in Puerto Rico (30), Singapore (31), Iran (32), and China (33), (34), (35). Thus, drinking any liquid (coffee, tea), even Yerba Mate, at very high temperatures and in large quantities over time may increase the risk of esophogeal cancer. Unfortunately, a large number of Yerba Mate cultures drink it at too high of a temperature, and scold their throat over 5 times a day, taking more than just a few sips each time. In some Latin American cultures it is considered cool, or machismo, to drink the water at a very hot temperature. This type of abusive treatment of the body has been connected to an increase in cancer.  The American Association for Cancer Research notes that consumption in larger quantities and at very hot temperatures is "associated with an elevated risk of esophageal cancer"(2003).

So, although Yerba Mate has been shown to inhibit and kill cancer cells, it is not amazing enough to protect your from constant burns to your throat. You can read more about safe yerba mate temperatures, so that you can imbibe the nutrients safely. Basically, don't drink scolding hot liquids! Turns out that burning your throat is not a wise way to treat the body. Fortunately, turns out that drinking yerba mate at the recommended temperatures is a wise way to treat your body!

"Yerba mate (Ilex paraguariensis) is rich in several bioactive compounds that can act as free radical scavengers. Since oxidative DNA damage is involved in various pathological
states such as cancer, the aim of this study was to evaluate the antioxidant activity of mate tea as well as the ability to influence DNA repair ... The regular ingestion of mate tea increased the resistance of DNA to H2O2-induced DNA strand breaks and improved the DNA repair after H2O2 challenge in liver cells, irrespective of the dose ingested. These results suggest that mate tea could protect against DNA damage and enhance the DNA repair activity. Protection may be afforded by the antioxidant activity of the mate tea’s bioactive compounds." Yerba Mate Antioxidants/Anti-Cancer: Daniel D. C. Miranda, et al. Protective effects of mate tea (Ilex paraguariensis) on H2O2-induced DNA damage and DNA repair in mice. Mutagenisis (2008)
