A British Medical Study Has Shown That Licorice Extracts May Improve Memory In The Elderly

High levels of the stress hormone cortisol, which damages the hippocampus, a part of the brain responsible for memory, is thought to be the culprit. The 众购彩票登陆licorice extract inhibits the activity of an enzyme in the brain that increases cortisol levels.

licorice extract for medicine

A drug based on the compound, progesterone, has been used to treat stomach ulcers and other ailments. In the new trial, older men aged 55 to 75 were given the drug three times a day for four weeks. Twelve of the men, who had type ii diabetes, had varying degrees of impaired memory, but after a few weeks, the tests showed that all the participants had improved their word memory by about 10 percent.


Professor Jonathan secco, from the university of Edinburgh, who led the study, said that while the effect was not dramatic, the memory of the older people was certainly better than before the medication。 He explained that word memory comes into play when a person recalls recent information received from outside, such as the time of an appointment, and is essential for normal functioning。


In the next five years, secco believes the compound could be used to improve memory in the elderly and possibly even treat conditions such as alzheimer's disease. There are a number of ways to improve memory that have worked well in animal studies, he said, but there are hurdles when it comes to moving to clinical trials. "in this trial, at least in a small population, we have preliminary data that this compound is a good candidate," he said.


But he cautioned that eating licorice directly did not improve memory compared with taking a drug made from the licorice extract, possibly because the active components of the compound entered human cells more easily when the drug was made。 Secco warns that the active ingredient in the drug can cause high blood pressure in people with serious side effects。 In the trial, the researchers also gave the elderly a second antihypertensive drug to reduce side effects。


The aging of the population in developed countries means that more and more people are facing problems such as memory loss. A spokesman for the charity care for the elderly welcomed the new findings and called for further research into the effectiveness of the drugs.
