Yin = and
corresponds to darkness, cold, wetness
Yang =
and corresponds to lightness, heat, dryness
Theory =
humans have both the Yin and Yang components and you are a male because more
Yang is expressed than Yin and visa versa.
When you
become ill it is because the Yin and Yang components are out of balance and
therefor if you have a fever (to much Yang) you take those herbs that belong
to the Yin family of medicines.
If you feel
depressed (to much Yin) you would take those medicines belonging to the Yang
family of medicines.
Greek humoral
theory
Humans consist
of four houmorals:
Body humorals = blood - phlegm - yellow bile - black
bile
Earth humorals = earth - air - fire -
water
The relative
amount of each body humoral determines
your character and disposition.
The natural humorals govern our well being.
