Two More Plants That Fight Against Alzheimer’s and Parkinson’s

 

The fight against the debilitating effects of Alzheimer's and Parkinson's diseases may have just gotten a new weapon from both a land-based and sea-based plant in the Mediterranean basin.

Researchers at the University of Malta (UM) have found that an extract from the prickly pear cactus and brown seaweed known as peacock's tail – which both grow in the region – might help disrupt a key process in which both diseases take hold.

Sure enough, the extracts worked once again. When given the seaweed extract, the median lifespan of the flies was extended by two days. When the prickly pear extract was used, the life extension doubled to four days.

“Considering that one day in the life of a fruit fly is equivalent to around one year in humans, the results are dramatic,” says a UM report on the study. “Interestingly, the mobility of sick flies was improved by about 18 percent after treatment, highlighting a significant improvement.”

Next, the researchers figured out that in flies whose brains were stacked with alpha-synuclein, a sticky protein that plays a role in Parkinson's disease, treatment with the natural substances again prolonged their lives. They concluded that the extracts limit the buildup of the sticky proteins into large clumps that can harm the nervous system, thereby helping to keep both Alzheimer's and Parkinson's at bay.
