I went to see a healer recently and he recommended clove tea to help clear my arteries. Tastes pretty good too, apart from the tannin. Here's the recipe if you're interested.
Take 40mls of the concentrate in hot water, twice a day.
Recipe - measure 16 cups of water into a pan. Add a packet (40g) of powdered cloves and 10 black tea bags to the water. Heat and when it comes to the boil, reduce heat and simmer for one hour. Strain through muslin or similar and bottle. Keep bottles in fridge or dark pantry.
