     There are three branches of medicine. One is called "doctor medicine" or "scientific medicine".

Scientific doctors try to observe sickness,  look for logical pattern,  and then find out how the human

body works. From there they figure out what treatments may work. This kind of medicine is believed

to date from the 4th century BC. Although nowadays it is successful,  in the ancient this approach(方

法) probably did not cure many patients.

     The second kind of medicine is called "natural cures" or "folk medicine",  in which less educated

people try to cure sickness with various herbs(中草药). These folk healers also use observation and

logic,  but they are not so aware of it. They try things until they find something that seems to work,  

and then they keep doing that. Folk medicine flourished(兴起) long before the development of scientific

medicine and was more successful in ancient times.

     The third kind is called "health spas" or "faith healing". Sometimes this may be as simple as touching

the holy man and being immediately healed. Other times,  a magician may make you a magic charm,  

or say a spell(咒语),  to cure you. Some religious groups organize healing shrines(圣坛) for the sick.

In these places people rest,  get plenty of sleep,  eat healthy food,  drink water instead of wine,  and

exercise in various ways. They also talk to the priests(牧师) and pray to the gods. If you are feeling

depressed or you have been working too hard,  going to these places may be just the right thing to

make you feel better.
