“It turns out that there are compounds in rosemary that may be responsible for changes in memory performance.
One of them is called Eucalyptol (1,8-cineole ) as well as smelling wonderful it may act in the same way as the drugs licensed to treat dementia, causing an increase in a neurotransmitter called acetylcholine.
These compounds do this by preventing the breakdown of the neurotransmitter by an enzyme.
“The implications of this kind of research are huge.”

“The Acciaroli study group is known to have very low rates of heart disease and Alzheimer’s. It favors a Mediterranean diet markedly infused with the herb rosemary.”
“The results from studying the longevity of this group could be applied to our practice at UC San Diego and to patients all over the world.”

“They eat rosemary almost every day, and they grow it – maybe this does something that helps. We know that rosemary improves brain function.”

“Considerable evidence also suggests that rosemary extracts, or its isolated components, can retard chemically induced cancers.”

“Rosemary extract and its hexane fraction are important for the prevention of phosphorylation of MAPKs, thereby blocking NF-kB activation, which in turn leads to decreased expression of iNOS and COX-2, thus preventing inflammation.”

“Natural anti-inflammatory compounds abound in the herbal world and are found in green tea, the spices turmeric and rosemary, feverfew and others. Because the use of nonsteroidal anti-inflammatory drugs (NSAID) is associated with a reduced risk for several cancers, it is at least plausible that natural NSAID should be explored for possible use as cancer preventives.”

“Rosemary (5% and 0.5%) significantly inhibited arterial thrombus formation. Only the higher concentration of common thyme (5%) had a significant antithrombotic effect. In 5% concentration, both rosemary and common thyme significantly inhibited platelet reactivity and enhanced the flow-mediated vasodilation.”
