Wind is a yang pathogenic factor
and is characterized by
Wind is a yang pathogenic factor
and is characterized by "upward and outward
dispersion." It can therefore easily
invade the upper part of the body, i.e. the
head and face, and the exterior portion of
the body, leading to impairment of the
opening and closing of the pores. Clinical
manifestations are headache, nasal obstruction, itching or pain in the throat, facial puffiness, aversion to wind and - sweating.

Urticaria is characterized by itching of the skin and wheals
- Wind in nature blows in gusts and is characterized by rapid changes.
Disorders caused by pathogenic wind, therefore,
are marked by migratory symptoms,
rapid changes and abrupt onset of disease.
The migratory joint pain of wandering

- syndrome, for example, which
is caused by pathogenic wind, is known as

- bi syndrome. Urticaria caused by
pathogenic wind is characterized by itching
of the skin and wheals which appear
- and disappear from place to place.

dizziness, vertigo,
fremitus, convulsions

movement. Moving pathogenic wind in
the body can cause dizziness, vertigo,
