What is sanguineous?

Sanguineous refers to something that is related to blood or has blood in it. The term is often used in medical contexts to describe the presence of blood in a bodily fluid or tissue, such as sanguineous drainage from a wound. Sanguineous fluids are typically red in color due to the presence of hemoglobin and other blood components. In some cases, the term may also be used more figuratively to describe someone who is optimistic, cheerful, or confident – a meaning that derives from an ancient Greek concept linking the blood with emotional temperament.
