Common herb could hold the key to protecting against Alzheimer's

A common herb could hold the key to protecting against Alzheimer's, after research revealed protein build-ups linked to the condition were diminished by a plant compound.

The herb can assist in regenerating brain synapses whilst also reducing inflammation and easing oxidative stress.

The aromatic herb has demonstrated encouraging outcomes in combating Alzheimer's disease - with scientists hopeful additional research and clinical trials of the plant may provide a fresh method for treating the condition in years to come.

The Mediterranean herb flourishes widely across the UK and you likely already possess some in your kitchen cupboard.

Rosemary has been celebrated for centuries for its qualities, with ancient Greeks acknowledging its potent impact on the mind and body, reports the Mirror.

An old English proverb from 1607, by Doctor of Divinity Roger Hacket, declared: "Speaking of the powers of rosemary, it overtoppeth all the flowers in the garden, boasting man's rule. It helpeth the brain, strengtheneth the memorie, and is very medicinable for the head."

Fast forward to today and researchers in California have created a new chemical compound, a stable derivative of rosemary and sage plants, claiming it has already produced promising results in mice in the battle against Alzheimer's symptoms.

The compound occurs naturally in the herbs, with the dried leaves of rosemary and sage containing up to 2.5 percent of carnosic acid. Carnosic acid, known for its anti-inflammatory and antioxidant properties, is unstable in its pure form.

However, researchers have now conducted a study using a newly-developed stable derivative of the compound on mice carrying an Alzheimer's gene.

The study revealed when the mice were given this modified stable compound, it resulted in reduced inflammation and improved memory.

Furthermore, the mice exhibited an increase in neuron synapses (the transmission of nerve signals) and a greater removal of toxic proteins, which are associated with Alzheimer's disease.

The excessive accumulation of proteins linked to Alzheimer's was diminished in the brains of the mice, with no recorded toxic effects. This process effectively combated inflammation and oxidative stress while also promoting synapses in the brain.

Rosemary also aids in stimulating blood circulation, thereby delivering more oxygen and nutrients to the brain and other organs. This could be another reason why this herb is beneficial for both the body and mind.

The herb possesses anti-inflammatory and antioxidant properties (which help remove damaging oxidation in cells), largely due to the carnosic acid present in the plant. Therefore, whether it's fresh or dried, rosemary could be a valuable addition to your daily diet.
