Natural health: I'm fit and healthy but have high blood pressure 

A quarter teaspoon of cinnamon daily can help prevent high blood pressure and heart disease

Diet and exercise are key to any lifestyle change

I'm a fit man in my 60s, a non-smoker, a moderate drinker, and a healthy weight. I was diagnosed with high blood pressure about two years ago. I was put on medication by my GP, but my blood pressure is increasing a little again. Are there any natural products that can be used to lower it?
