NVS Himalayan Green Tea is often drunk for its positive health benefits, and in recent months new research has added to mounting evidence supporting this view by finding that it can even help to improve memory.
Researchers at Newcastle University found that green tea inhibited the activity of key enzymes in the brain associated with memory, and they believe their findings, published in Phytotherapy Research could herald the development of a new treatment for Alzheimer’s disease.
The team, from Newcastle University's Medicinal Plant Research Centre, investigated the properties of coffee, green tea and black tea in a series of scientific experiments. They found that both green and black tea inhibited the activity of enzymes associated with the development of Alzheimer's Disease, but coffee had no significant effect.
Both teas inhibited the activity of the enzyme acetylcholinesterase (AChE), which breaks down the chemical messenger or neurotransmitter, acetylcholine. Alzheimer's is characterised by a drop in acetylcholine. Green tea and black tea also hinder the activity of the enzyme butyrylcholinesterase (BuChE), which has been discovered in protein deposits found on the brain of patients with Alzheimer's.
Green tea went one step even further in that it obstructed the activity of beta-secretase, which plays a role in the production of protein deposits in the brain which are associated with Alzheimer's disease. Green tea also continued to have its inhibitive effect for a week, whereas black tea's effect on the enzymes lasted for only one day.
Lead researcher Dr Okello, himself a green tea drinker, said the findings of the research suggested tea could boost the memory of everyday drinkers: "The ageing politician, Tony Benn, is a prime example of somebody who drinks tea and has a fantastic memory."
Although this antioxidant rich beverage has proved promising in these early trials, it hasn’t yet been determined how much green tea is needed to have a therapeutic effect.
The Newcastle University researchers are now seeking funding to carry out further tests on green tea, which they hope will include clinical trials. Their aim is to work towards the development of a medicinal tea which is specifically aimed at Alzheimer's sufferers.
Shandip Shah, Director of NVS Himalayan Green Tea says ‘There is increasing scientific research taking place, highlighting the benefits of antioxidants in promoting a healthy heart, prevention of cancer and helping comfort and guard against diseases like diabetes, high blood pressure, tumours, ulcerations, inflammation, intestine problems, dental decay and more. This new research only adds to the proven benefits of our healthy brew.’
And NVS Himalayan Green Tea tastes great. In addition to the standard green tea, the Himalayan range has eight different flavours including organic, refreshing mint, ginger, lemon, cardamom, jasmine, Earl Grey and spicy masala.
