#The vinca rosea plant ensures brain health. Its active ingredients improve blood supply to the brain, increase the level of oxygen that the brain can utilize. It also raises serotonin levels and prevents abnormal coagulation of blood.
#The alkaloid vincamine keeps the blood thin and has memory enhancing properties. It is therefore useful in preventing dementia, especially vascular dementia.
