May promote brain health and improve mood

Sage is frequently used in alternative medicine to enhance mood, and memory, and to help prevent brain illnesses such as Alzheimer's. Many of these applications are supported by scientific studies. Alzheimer's disease advances owing to the formation of amyloid plaques in the brain. Several animal and test-tube studies suggest that sage and rosmarinic acid may help prevent the development of these plaques.

Furthermore, several human studies show that sage extracts boost memory, brain function, mood, and attention. In one research of 135 individuals, merely smelling the perfume of this plant improved memory and mood when compared to a control group. Sage may also help with pain relief, although a further study on its effects on the brain and neurological system is needed.
