What for generations was considered just an aromatic plant, today is revealed as a brain protector, capable of improving memory, stimulating cerebral circulation and fighting Alzheimer's.

Rosemary, that plant with its fresh, Mediterranean scent, has been used for centuries in cooking and natural medicine. But new scientific studies are showing that its potential goes far beyond flavor: it could be a shield against Alzheimer's.

Researchers have discovered that rosemary contains antioxidant compounds such as carnosic acid and carnosol, which can protect brain cells from oxidative damage, a key factor in the development of Alzheimer's disease. Furthermore, these components appear to stimulate blood circulation in the brain, improving the supply of oxygen and nutrients.

But that's not all. Rosemary also acts on neurotransmitters, especially acetylcholine, which is directly related to memory and learning. By inhibiting the enzyme that breaks down this neurotransmitter, rosemary helps improve concentration, memory, and mental alertness.

Preliminary studies in older adults have shown slight but sustained improvements in cognitive tests after consuming rosemary extracts or including the plant regularly in their diet. Although it does not yet replace medical treatments, its value as a natural supplement is being seriously considered by neurologists and scientists.
