Medicine
Through
Time
- Prehistory (ã 3000BC)
- Before written
records
- Knowledge about
their way of life
comes from
archeological finds
and the current
culture of people
who haven't changed
their living ways
- Nomads - people who
travelled in search of food,
following animals to survive
and had temporary shelters
- Believed in the
supernatural and
thought that evil
spirits caused disease
- To treat people,
herbal remedies
would often be
given
- People would go to see a medicine
man (half priest, half doctor), so he
could use trepanning ( cutting a hole
in the skull ) to 'get rid' of evil spirits
- Slow progress as they believed
in superstitions and the
supernatural, even though cave
paintings show bulls with
daggers in their hearts, showing
they had little understanding
- Ancient Egypt
(3000BC - 400BC)
- Thought the
body's channels
became blocked
just like the Nile
- The body could only be
treated by taking laxatives,
vomiting or being leeched

gained and shared
their knowledge
- First people to write
using hieroglyphics
on papyrus
- Still believed in the
supernatural and that
wearing charms would
ward away evil spirits
- Carried out simple
operations, like
cutting tumours
- Mummification helped them learn
about the locations of vital organs
but the heart and brain were not
allowed to be touched as it was a
religious ceremony, so it had to be
done as quick as possible
- Ancient Greece (800BC - 400BC)
- Built healing
temples called
Asclepions, named
after the Greek God
of healing, Asclepius
- At an Asclepion the sick would
bathe, make a gift to the gods
and rest and would sleep in a
dormitory and be cured by
Asclepius' daughters' and a snake
- A typical Asclepion consisted of
baths, gyms, an athletic stadium
and a theatre seating 14,000 people
- Carried out simple operations
using simple surgical tools during
wars and learnt about setting
broken and dislocated bones, even
though it was little surgical
progress compared the Egyptians
- They came to believe that
disease had natural causes
and could be prevented and
believed in keeping themselves
clean. they also tried to eat
the corret food for the time of
year and tried to exercise
- HIPPOCRATES put forward the
theory of the four humours, that
the body had to be in balance and
were connected to the seasons. It
was incorrect but set medical
development in the right directions
- HIPPOCRATES also believed in
clinical observation, that doctors
had to observe their patient,
recognise an illness and suggest
a cure. He also stated that
personal hygiene and exercise
could prevent disease
- ARISTOTLE'S studies led HIPPOCRATES
to suggest that the heart provides heat
to the body while the brain cools it
down. Although this was wrong, it
provided a better understanding of the
function of the heart in the body
- A medical library was built at
Alexandria, which became the
centre of all medical knowledge

places near good springs,
rivers or wells

to the valleys

and sewers to
improve hygiene
- GALEN built on four
humours by saying that if
you were too hot, for
example,, then you would
need cooling down
- GALEN wrote over 350 medical books,
which were the foundation of learning
for the next 1400 years. His ideas were
accepted because they fitted with the
ideas of the Christian Chruch

getting a better understanding
of the anatomy. He famously
demonstrated how the nervous
system worked, even though it
was on a pig

Europe (500AD -
1500AD)

were used, like blood
letting, leeching, and
testing urine
- Public health grew
worse, rivers were used
as dumps for sewage
and a source of
drinking water

put into place
