Ginsenosides can modulate immune functions, counteract oxidative stress, and promote remyelination in demyelinating injuries caused by inflammatory conditions.

Resveratrol exhibits antioxidant and anti-inflammatory properties, alleviating the symptoms of chronic demyelinating diseases induced by metabolic disturbances.
