Black Tea Health Benefits

Red tea dehydrates, milk cancels the antioxidants, it has no caffeine, it is a different plant from green tea: six claims tested against the data.

Red tea has more caffeine than green, so timing matters more. When to drink it, why breakfast is contested, and the cut-off before bed each night.

Red tea's cautions are caffeine, iron and warfarin, not the green tea extract warning. Who should limit it, and why the extract risk does not transfer.

Red tea suits cold constitutions and weak digestion best. Daily amounts by group, with caffeine ceilings set by its 40 to 70 mg per cup of tea.

Red tea research is smaller than green tea's. What the 1.7 million participant cohort found, what the LDL trials measured, and where evidence stops.

Chinese medicine classes red tea as warm, sweet and entering the heart, spleen and stomach. Why oxidation flips the nature, and who it suits.

Black tea's catechins are converted into theaflavins and thearubigins by oxidation. Measured levels, the four theaflavins, and why they matter.
