What magical belief do Italians have about good and bad blood?

The belief that bad blood can lead to curses and illness is rooted in traditional Italian folklore and superstitions. In many cultures, including Italian, blood is often viewed as a vital essence that can carry not only biological traits but also moral and spiritual implications. The notion of "bad blood" suggests a lineage or family history that might bring misfortune, malaise, or even curses upon individuals or their descendants. This perspective can influence how families perceive their heritage and the health of future generations, reinforcing the idea that one’s bloodline can have a substantial impact on their fate and well-being.

In contrast to the belief in bad blood, the concept of good blood is also significant and commonly associated with vitality, strength, and positive attributes. However, the emphasis on bad blood as a source of potential curses or illness more directly aligns with Italian magical beliefs, capturing a deep-rooted cultural understanding of how familial and ancestral legacies can affect individuals.
