What is the name of the astrology-linked chart used by medieval doctors?

• A. Urine chart
• B. Temperature chart
• C. Zodiac chart
• D. Herbal chart

Answer: (C)

Astrology shaped how medieval doctors thought about health, linking celestial signs to parts of the body and to timing for treatments. They used a chart that maps the zodiac to different bodily regions—the zodiac chart—so they could plan interventions like bleeding or prescribing remedies according to which signs were believed to influence a given area or time.

That makes the zodiac chart the best answer because it directly represents the star-based, astrological approach used in medieval medicine. A urine chart, a temperature chart, or a herbal chart are focused on fluids, measurements, or remedies, not on the astrological mapping that guided diagnosis and treatment in that era.
