Secondary Symptoms: Su Wen Ch. 30 describes Yangming symptoms in detail:
"When the foot yang brilliance vessel has a disease, [the patient] has an aversion to [other] people and to fire...
When the disease is severe, then [the patient] throws off his clothes and runs around.
He climbs on what is high and sings.
In some cases he even fails to eat for several days and [yet] he leaps over walls, and he climbs on houses.
All the places he climbs on, he would ordinarily not be able [to reach].
Being ill, though, he is able to do so...
He [utters] absurd words and voices insults, without sparing those near or distant to him" (trans. Unschuld & Tessenow, 2011).
