Wissenschaftler haben zum ersten Mal die Wirkung von Matcha-Tee-Pulver und -Extrakt bei der Verringerung von Angstzuständen in einem Tiermodell nachgewiesen. Matcha ist eine sichere, natürliche Alternative, um Angstzustände zu lindern und die Stimmung zu heben.
Stimmung und Angst disorders are becoming commonplace in our fast-paced and often stressful lives. Angst & Sorgen disorders and fear has been linked to disturbance in dopaminergic and serotonergic systems in our brain. Angst & Sorgen symptoms also increases risk of other medical disorders and affects overall wellbeing of a person. Anxiolytic (or antianxiety) agents like benzodiazepines and serotonin inhibitors are generally used for treatment as they reduce or inhibit Angst. However, they have many side effects, sometimes even adverse, and they also increase dependency. Safer, natural alternative need to be developed for Angst Management.
In Japan wird „Matcha“ seit langem für verschiedene medizinische Zwecke verwendet. Matcha wird eine fein gemahlene Kraft aus neuen Blättern einer Baumpflanze genannt Camellia sinensis die nur im Schatten wachsen darf. Matcha-Pulver wird zur Herstellung verwendet Matcha Tee by adding it directly to hot water. It is also used for adding flavour to food. Matcha Tee is different from regular green tea in its content mainly because of differences cultivation and processing. Camellia sinensis Pflanze ist reich an L-Theanin, Epigallocatechingallat (EGCG), Koffein, Vitaminen und Aminosäuren und daher bietet der Verzehr von Matcha mehrere Vorteile, die mit diesen bioaktiven Substanzen verbunden sind. Es wird in Japan häufig zur Heilung, Entspannung und sogar Behandlung von Hauterkrankungen verwendet. Es gibt jedoch nur sehr begrenzte wissenschaftliche Beweise, um die oben genannten Behauptungen zu stützen. Auch die Auswirkungen von Matcha-Pulver auf Verhaltensaspekte wurden bisher nicht untersucht.
Eine Studie in den veröffentlichten Zeitschrift für funktionelle Lebensmittel has investigated and demonstrated the effects of Matcha Tee powder, hot water extract and ethanol extract for Angst vor Angst activity in an animal model (here, mice). Researchers conducted an elevated plus maze (EPM) test in healthy animals. EPM involves use of an elevated plus-shaped platform which has two open arms and two closed arms with walls around it. It is a commonly used anxiety test in which animal subjects which are anxious try to stay on the safe area of the plus where they cannot fall off.
The animals were orally administered Matcha powder and extract or fractions dissolved in water. Results showed that the animals who had consumed Matcha had reduced Angst. The strongest effect was seen in Matcha extract derived using 80% ethanol when compared to extract derived from hot water. This meant that poor water-solubility of Matcha has better Angst vor Angst effect than when it was easily water soluble. The ethanol extract was fractioned further into hexane soluble, ethyl acetate soluble and water-soluble fractions which exhibited similar results. Behavioural analysis showed that Matcha power and extract reduce Angst by activating dopamine D1 and serotonin 5-HT1A receptors which are closely linked to anxious behaviour.
The current study conducted on mice demonstrates that Matcha Tee powder and extract have a positive calming effect and reduce anxiety by activating dopaminergic and serotonergic systems in the brain. Matcha is a safe and natural alternative for alleviating anxiety.
