What Does 'New Blood' Mean?

This idiom typically refers to new people or fresh individuals who join a group, organization, or community. It suggests infusing new ideas, energy, perspectives, or talents into a situation.

Where Does 'New Blood' Come From?

The idiom has roots in medieval medical beliefs. In medieval times, a person's health and vitality were determined by the balance of four bodily humors: blood, phlegm, black bile, and yellow bile. The concept was part of the ancient Greek theory of humorism, which suggested that an imbalance in these bodily fluids could lead to illness.

'New blood' referred explicitly to fresh, recently circulating blood. The idea was that introducing new blood into the body could have rejuvenating effects and restore balance. Over time, the term evolved metaphorically to refer to the introduction of new individuals or ideas into a group or system to bring about revitalization and innovation.

The metaphorical sense of 'new blood' has been used for several centuries, evident in written texts from the 19th century. For instance, in the mid-1800s, you can find examples in literature and newspapers where 'new blood' describes the infusion of fresh ideas or individuals into groups.
