Medieval medicine
GCSE History Medicine through Time: how Hippocrates, Galen and the Church locked England into the four humours, miasma and prayer from c.1250 to 1500.
If the explanation is imbalance and sin, the treatment will be bleeding, purging and prayer.
The important bits
What you need to know
- 1
Learned medieval medicine in England (c.1250–1500) rested on Hippocrates (c.460–370 BCE) and Galen (129–c.216 CE): illness as imbalance of blood, phlegm, black bile and yellow bile.
- 2
Galen’s theory of opposites told physicians to treat an excess with its contrary — bleed a “hot” patient, warm a “cold” one — so diagnosis was about restoring balance, not killing a germ.
- 3
The Christian Church copied, licensed and taught Galenic texts in cathedral schools and later universities (Oxford, Cambridge). Challenging Galen could look like challenging God, which slowed anatomical correction.
- 4
The Church also supplied a supernatural explanation: God sent disease as punishment or trial. Prayer, pilgrimage, confession and the cult of saints (St Roch against plague) sat beside learned physic.
- 5
Astrology and miasma filled the gaps. Planetary conjunctions were thought to corrupt the air; sweet-smelling fires, pomanders and flight from “bad air” were rational inside that theory.
- 6
Care was stratified. University-trained physicians served the rich; barber-surgeons (Company of Barbers, later merged with surgeons) let blood and lanced boils; apothecaries sold herbs; wise women and midwives treated most ordinary people.
- 7
Hospitals such as St Bartholomew’s (founded 1123) and St Thomas’ were often run by religious houses. They offered care, rest and last rites more than surgical cure; the Dissolution of the Monasteries (1536–40) later wrecked that network.
- 8
Continuity is the exam point: until the explanation of disease changed, treatments could not jump. Bleeding, purging, herbal remedies and prayer still dominated English practice in 1500.
Quotations worth analysing
Short evidence. Real method.
“Nature is the healer of disease.”
The line explains why learned doctors watched diet, rest and evacuation rather than hunting a specific cause: the body was a balance to restore. GCSE answers should use it to show theory shaping treatment.
“The physician must be a philosopher as well as a healer.”
Galen’s authority was intellectual, not experimental in the modern sense. Because the Church preserved his books, philosophy outranked dissection, which is why anatomy stagnated even when surgeons saw bodies daily.
“God’s hand, not man’s, sends the pestilence.”
A supernatural cause made flagellation, scapegoating and prayer logical responses. Examiners want you to treat this as a coherent world-view, not as simple stupidity.

Why the four humours were a closed system
Medieval English medicine was not a vacuum of ignorance. It was a working system. Hippocrates and Galen offered a complete map of the body: four humours, four elements, four seasons. A fever, a cough or melancholy all fitted. Because the map seemed complete, new observations were forced into it rather than allowed to break it. The Church amplified that closure by copying Galenic manuscripts and licensing physicians. Barber-surgeons and wise women practised empirically — wine on wounds, herbal poultices — but they lacked a rival theory that could dethrone Galen in the universities. That is why c.1250–1500 is taught as continuity of explanation, even when individual remedies changed. In essays, argue that the limit was intellectual and institutional, not a shortage of sick people to observe.

Who actually treated the sick?
A 16-mark question on “medieval medicine” that only names Galen has missed the social history. Most English people never saw a university physician. They used parish priests, midwives, apothecaries and travelling empirics. The 1512 Medical Act later tried to licence practice in London, showing how unregulated care had been. Hospitals attached to monasteries provided beds and spiritual care; they did not run operating theatres. Gender matters: women dominated birth and household physic, then were increasingly squeezed as male colleges professionalised. Change in who held authority is slower than change in a famous book. Use this to complicate “the Church blocked progress” — the Church also staffed the only free beds many towns had.
See the idea in action
Question: “The Church was the main reason medieval medicine did not improve.” How far do you agree? Judgement: the Church was a major brake because it preserved Galen and explained disease as sin, but it was not the only one. Paragraph 1: monasteries copied Galenic texts; dissection of humans was rare; pilgrimage and prayer were official responses to plague. Paragraph 2: the four-humour theory itself, inherited from Hippocrates and Galen, made bleeding logical even without the Church. Paragraph 3: technology (no microscopes) and social structure (few physicians, local empirics) meant no rival explanation could spread. Conclusion: the Church amplified a closed classical system; without a new cause of disease, treatments could not jump, Church or no Church.
Exam technique
Turn knowledge into marks
Periodise as c.1250–1500 and name Hippocrates, Galen, the four humours and a religious response. “People were uneducated” scores almost nothing.
Common mistakes
Do not give these marks away
- 01
Writing as if medieval people had no medical system — they had a sophisticated, wrong one.
- 02
Blaming “the Church” for everything without mentioning Galen’s theory of opposites or miasma.
- 03
Assuming hospitals cured disease; they mostly offered care, rest and last rites.
Why did medieval learned doctors bleed patients?
AThey had identified bacteria in the blood and wanted to flush them out
BGalen’s four-humour theory treated illness as imbalance, so removing blood restored balance
CThe 1512 Medical Act required bleeding once a year
DHippocrates had proved that germs caused fever
Show the answer
Galen’s four-humour theory treated illness as imbalance, so removing blood restored balance. Bleeding was rational inside humoural theory. It looks absurd only if you smuggle germ theory backwards into the Middle Ages.
Quick questions
If this is the bit you searched
Did anyone dissect bodies in medieval England?
Rarely, and usually animals or executed criminals under tight control. Galen had dissected animals, which is why his anatomy of the human body was wrong in places. Systematic human dissection waits for the Renaissance faculties.
What is miasma?
The idea that poisonous, smelly air causes disease. It encouraged cleaning streets and avoiding swamps, which sometimes helped, but it did not identify microbes or contaminated water as the specific cause.
Were herbal remedies useless?
Not always. Willow bark (salicin) and some antiseptic herbs had effects. The problem was the explanation: herbs were fitted to humours and God, so they could not be developed into targeted drugs.
How should I use medieval medicine in a factors essay?
As continuity: religion, classical authority and limited technology locked the explanation. Later change then looks like a break, not a gentle slope.
