Black tea contains polyphenols, which are antioxidants, in its composition so it helps to block the oxidation of bad cholesterol (LDL), responsible for accumulating fat in the artery walls. And the caffeine in black tea helps to dilate blood vessels, helping to prevent heart attacks.

Quantity Recommendation

My recommendation for consuming black tea is to use approximately 6g or 0.21oz of dried black tea leaves for every half liter or 17us fl oz of boiling water and do not consume more thar half a liter or 17us fl oz per day, try to consume it gradually throughout the day and not at once.
