How were diseases treated during the renaissance?

During the Renaissance, diseases were treated using a mix of traditional herbal remedies, bloodletting, and the humoral theory, which posited that an imbalance of bodily fluids caused illness. Physicians often relied on Astrology and the alignment of the stars to diagnose conditions. Surgical practices were rudimentary, and treatments could include purging and dietary changes. Overall, medical understanding was limited, leading to a reliance on superstitions and folk remedies alongside emerging scientific ideas.
