Also called shenkui in China
A Chinese folk label describing marked anxiety or panic symptoms with accompanying somatic complaints for which no physical cause can be demonstrated. Symptoms include dizziness, backache, fatigability, general weakness, insomnia, frequent dreams, and complaints of sexual dysfunction (such as premature ejaculation and impotence). Symptoms are attributed to excessive semen loss from frequent intercourse, masturbation, nocturnal emission, or passing of "white turbid urine" believed to contain semen. Excessive semen loss is feared because of the belief that it represents the loss of one's vital essence and can thereby be life threatening.
