Purpose: Knowing the effect of eating dark chocolate to reduce blood pressure in elderly people with hypertension. Methods: Case study by applying implementation according to evidencebased practice in nursing care.

The benefits of flavonoids can also lower blood pressure in elderly people suffering from high blood pressure. Conclusion: There is an effect of giving dark chocolate on lowering blood pressure in elderly people with hypertension based on the results of blood pressure measurements before and after the intervention during the intervention period. the results of blood pressure measurements before and after giving the intervention for 7 days.
