An extract from cinnamon - called CEppt - slows the progression of the disease, researchers from Tel Aviv University discovered in a laboratory test with mice. They ground cinnamon, and the extract was added to the mice's drinking water. They started to see a positive effect after four months, and the process where plaque deposits appear in the brain had slowed significantly.
The researchers believe that CEppt even has the ability to reverse Alzheimer's.
There's one catch. CEppt has a therapeutic quality at around 10 grams of raw cinnamon a day - and that's toxic.
The next stage is to develop a supplement that everyone can take safely, say the researchers.
