A new study highlights the positive qualities of matcha tea, a quality of Japanese tea that is becoming increasingly popular. Originally from China and made from the Camellia sinensis green tea plant, this tea has a particular process with regards to its preparation: the leaves are steamed, then dried and then ground to obtain a very fine powder.
In Japan, this tea has a long history behind it even as a medicine or relaxing compound even though there is little scientific evidence to emphasize this.
The new research, conducted by Japanese scientists at the University of Kumamoto, shows that this particular quality of tea can help reduce anxiety in mice.
The mechanisms that help in this regard are related to the activation of dopamine D1 receptors and serotonin 5-HT 1A receptors. These are two types of receptors already known because they are linked to anxious behavior.
The researchers conducted a rodent anxiety test that sees the most anxious subjects spend more time in the walled, and therefore safer, areas of a particular maze.
The researchers first made some of the mice extract matcha extract and then conducted the experiment: the results clearly showed the reduction in anxiety in mice that took the extract.
Yuki Kurauchi, the lead author of the study, admits that further epidemiological research will be conducted but these studies show at the time that matcha tea “can be very useful for the human body.”
