煮作稀糜，去渣，和散，温顿服之。不吐者，少少加，得快吐乃止，诸亡血虚家，不可与瓜蒂散。此即
《论》中所云吐法也。栀子豉汤治虚烦，非专引吐，此方则专于引吐而已。
病如桂枝证，头不痛，项不强，寸脉微浮，胸中痞硬，气上冲咽喉，不得息者，此为胸中有寒也，
寒必兼饮。当吐之，在上者越之。宜瓜蒂散。《本草》瓜蒂∶病在胸腹中，皆吐下之。
病患手足厥冷，脉乍紧者，邪结在胸中，所以阳气不能四达。心中满而烦，饥不能食者，病在胸中，
当须吐之，宜瓜蒂散。

属上焦也。上焦指胸中，阳明乃中焦也。
少阴病，吐利，手足逆冷，烦躁欲死者，吴茱萸汤主之。此胃气虚寒之症。
干呕吐涎沫，吐涎沫，非少阳之干呕。然亦云干呕者，谓不必食谷而亦呕也，头痛者，阳明之脉上于
头。吴茱萸汤主之。此胃中有寒饮之症。
