RELATED TO CANCER
Drinking very hot yerba mate is associated with a higher risk of cancer than drinking yerba mate at cooler temperatures, according to the health organization.
A review article published in the BMJ cited research that found that drinking “very hot” yerba mate was associated with an increased risk of esophageal cancer.
CONTENT OF MATE TEA
The Mayo Clinic states that mate tea contains polycyclic aromatic hydrocarbons (PAHs), which are known to cause cancer. There is also PAH, tobacco smoke and grilled meat.
A 2012 study conducted by University of Illinois scientists showed that colon cancer cells die when exposed to about the same number of bioactive compounds found in a cup of mate tea.
