Pine tree extract improves memory
AS festive-coloured pine trees start filling family lounges, scientists have revealed a radically different new use for the common forest tree.
Auckland researchers have extracted an antioxidant from the bark of the pine tree they have found can help treat people with a traumatic brain injury.
The extract, called Enzogenol, was given 60 people with a brain injury over three months, with results suggesting the drug can boost memory and improve attention span.
AUT stroke specialist Professor Valery Feigin said patients who took it were less likely to forget people’s names or basic directions, common problems for brain injury sufferers.
The results were great news as there were few evidence-based treatments for people with mild brain injury problems, she said.
“Other than brain exercises, there are limited treatments available to improve damage,” said Prof Feigin, who is hoping to launch a large-scale trial on the back of the successful pilot study.
Brain injuries caused by stroke, motor vehicle crashes, sports injuries, assaults and falls are the leading cause of disability and death in New Zealand, costing the country about $NZ100 million ($76.07 million) a year.
