One of the four humours, related to the season of spring and the element of air. It denotes a warm and moist temperament and the word ‘sanguine’ is often used to describe someone who is easy-going, well balanced, optimistic and cheerful; being in no way extreme in their reactions. In physiology the sanguine humour is traditionally reputed to be seated in the blood, which disseminates nourishment through the veins to support the principle of digestion.
