A study published in the October 2007 issue of Nature Reviews Neuroscience. and a study published online November 8 in the Journal of Neurochemistry, show that carnosic acid (CA), the active ingredient in the herb rosemary, activates a novel signaling pathway that protects brain cells from the free radical damage associated with stroke and other neurodegenerative conditions such as Parkinson's and Alzheimer's diseases.
CA from rosemary is proving to be neuroprotective, without producing the serious adverse effects characteristic of so many drugs used to treat neurodegenerative disease.
Rosemary has been used since the Middle Ages to treat disorders of the nervous system and to ward off sickness. However, the exact chemical pathways by which it works have, until now, been unknown.
Can you think of anything better than roasted potatoes with rosemary and garlic? If only someone would produce a low glycemic index potato!
