Учените демонстрират за първи път ефектите на прах и екстракт от чай Матча за намаляване на тревожността при животински модел. Matcha е безопасна, естествена алтернатива за облекчаване на тревожността и повишаване на настроението.
Настроение и безпокойство disorders are becoming commonplace in our fast-paced and often stressful lives. безпокойство disorders and fear has been linked to disturbance in dopaminergic and serotonergic systems in our brain. безпокойство 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 безпокойство. However, they have many side effects, sometimes even adverse, and they also increase dependency. Safer, natural alternative need to be developed for безпокойство управление.
В Япония "матча" се използва от дълго време за различни медицински цели. Матча е фино смляна сила от нови листа от дървесно растение, наречено Camellia sinensis което е позволено да расте само на сянка. За направата се използва прах мача Матча чай by adding it directly to hot water. It is also used for adding flavour to food. Matcha чай is different from regular green tea in its content mainly because of differences cultivation and processing. Camellia sinensis Растението е богато на L-теанин, епигалокатехин галат (EGCG), кофеин, витамини и аминокиселини и по този начин консумацията на Matcha осигурява няколко ползи, свързани с тези биоактивни вещества. Обикновено се използва в Япония за лечение, релаксация и дори лечение на кожни заболявания. Въпреки това има много ограничени научни доказателства в подкрепа на горните твърдения. Също така ефектите на Matcha на прах върху поведенческите аспекти не са изследвани досега.
Проучване, публикувано в Вестник на функционалните храни has investigated and demonstrated the effects of Matcha чай powder, hot water extract and ethanol extract for противостраховия 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 безпокойство. 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 противостраховия 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 безпокойство 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 чай 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.
