This paper summarized the ideas of MI Ziliang’s treatment of arthralgia syndrome. He believes that the core of arthralgia syndrome is blood stasis

and characterized by pain. The main pathological changes of arthralgia syndrome are the pathogens obstructing the meridians and qi and blood. "Blood stasis "is throughout the whole process of arthralgia syndrome. Accordingly

arthralgia syndrome is treated from 3 stages of early stage

middle stage and late stage. At the early stage

the body was attacked by the external contradiction of wind

cold

dampness heat

leading to disharmony of qi and blood

unsmooth movement of blood. Therefore

it should be treated by eliminating the evil. At the middle or late stage

the external pathogens and qi and blood were fighting in the meridians

leading to unsmooth movement of qi and blood in the meridians

and the blood stasis was formed. The treatment should focus on "unblocking"to activate blood circulation and qi movement

removing blood stasis and relieving pain. At the late and end stage

the healthy qi was damaged

and the deficiencies showed

especially blood deficiency and liver kidney deficiency

but the blood stasis still exist. The treatment should both tonify and nourish and resolve blood stasis.
