WANG Shouchuan holds that hidden wind internal immersing

exogenous wind inducing

stagnated heat damaging collaterals are the pathogenesis key of pediatric allergic purpura. The methods of clearing heat

removing wind and activating blood circulation to dissipate blood stasis should be used throughout the treatment. The disease could be treated in 3 phases

acute attack stage

clinical remission stage and chronic extension stage. At acute attack stage

according to children patients’ degree of wind

heat and dampness pathogen

the methods of dispelling wind-clearing heat

clearing heat-cooling blood and clearing heat-eliminating dampness are used respectively. At clinical remission stage

the methods of benefiting Qi-nourishing Yin and activating blood circulation to dissipate blood stasis are mainly used. At chronic extension stage

strengthening vital Qi is mainly used

combined with resisting exogenous wind and inhibiting hidden wind to prevent the disease recurrence.
