Strawberry leaf extract protects nerve cells from damage associated with Parkinson's disease

Strawberry leaf extract was able to protect nerve cells from damage characteristic of Parkinson's disease. This was reported by Japanese scientists, whose work was published in Frontiers in Nutrition.

The researchers first tested the extract on nerve cells exposed to rotenone, a toxic substance that causes oxidative stress and impairs mitochondrial function. Strawberry leaf extract helped cells survive, reduced the formation of harmful reactive oxygen species and restored the functioning of mitochondria, which provide cells with energy.

Then the effect of the extract was tested on mice with a model of Parkinson's disease. Animals treated with it had reduced loss of dopamine neurons, brain cells whose death plays a key role in the development of the disease. In addition, the mice showed less severe movement disorders.

Scientists associate the protective properties of strawberry leaves with the polyphenols they contain. These substances can activate natural mechanisms to protect nerve cells from oxidative stress and mitochondrial damage. The authors believe that in the future, compounds from strawberry leaves may become the basis for the development of new means of preventing or treating neurodegenerative diseases.
