Medicine
Medicine studies the diagnosis, treatment and prevention of diseases. In Dr Stone, it marks a major turning point: Senku synthesizes the first antibiotics (sulfa drugs) to cure pneumonia, makes clinical diagnoses and rebuilds a basic pharmacology from plants and chemistry.
Entries in this discipline

In The Apothecary Diaries, a body is examined. We explain autopsy, post-mortem signs, and the birth of forensic medicine.
Bear Bile
Its ursodeoxycholic acid (UDCA) dissolves some gallstones and protects the liver. Now made synthetically, it is on the WHO essential medicines list.
The Bezoar
Not a universal one: this digestive stone only binds some arsenic compounds. Where the legend came from, and the ox bezoar in The Apothecary Diaries.
Breech Presentation
Modest, low-quality evidence: doctors prefer external cephalic version, 50 to 60% successful. How Maomao spots a breech baby from the kicks, explained.
The Caesarean Section
Before antisepsis and anesthesia, caesarean section almost always killed the mother. We explain why, and what changed everything in the 19th century.
