The American Red Cross (and your favorite Tea Sommelier) encourages everyone who can give blood to do so. There is never enough on supply and that which is on hand has a relatively short shelf life.
But some generous folks take it even further, donating plasma, red cells, infection-fighting white cells called granulocytes, or platelets. The latter is especially useful for patients who recently underwent a bone marrow transplant or cancer and leukemia treatments, as many of these procedures leave the body low on platelets and vulnerable to any number of injuries and ailments.
However, platelets can be stored for only five days, so the need for platelet donations is especially vast and continuous. An answer to fulfilling this extreme demand may be on the horizon, though: tea.
It seems that tea is not just good for your cells while they are in your body, but even when they are not!
