白附丸(痰涎)
钱氏云∶吐泻，乳不化，伤食也，宜下之。冯承务子五岁，吐泻壮热，不思食饮。钱氏见目中黑睛少而
白睛多，面色 白，曰此子必多病，面色 白者神怯也，黑睛少者肾虚也，黑睛属水，本怯而虚，故多病也，
纵长成，必肌肤不壮，不奈寒暑，易虚易实，脾胃亦怯，更不可纵恣酒欲，若不保养，不过壮年也，面上
常无精神光泽者，如妇人之失血也，今吐利不食壮热者，伤食也。又虚怯不可下，下之，虚入肺则嗽，入心
则惊，入脾则泻，入肾则益虚，但宜以消积丸磨化之，为微有食也。如伤甚，则可下，不下则成癖也。若实
食在内，亦可下也，下毕，补脾必愈，随其虚实，无不效者。〔曾〕钱氏曰∶吐乳泻黄，是伤热乳，吐
乳泻青，是伤冷乳，皆当下之，此迎夺之法也。不若伤热者用五苓散以导其逆，伤冷者用理中汤以温其中，
自然平复。脾经积滞未除，再为饮食所伤，不吐则泻，不泻则吐，宜以三棱散化积，守胃散和中。

钱乙说：吐泻，乳汁不消化，是伤食所致，适宜采用攻下法。冯承务的儿子五岁，吐泻且壮热，不想饮食。钱乙看到他黑睛少而白睛多，面色苍白，说这个孩子一定多病，面色苍白说明神气怯弱，黑睛少说明肾虚，黑睛属水，本来怯弱又肾虚，所以容易生病，即使长大成人，也必定肌肉不健壮，不耐寒暑，容易虚实变化，脾胃也怯弱，更不可放纵酒欲，如果不保养，活不到壮年。面上常没有精神光泽的，就像妇女失血一样，现在吐利不进食且壮热的，是伤食。另外，虚怯体质不可攻下，攻下后，邪气入肺则咳嗽，入心则惊悸，入脾则泄泻，入肾则更加虚弱，只适宜用消积丸磨化积滞，因为只是轻微有食积。如果伤食严重，则可以攻下，不攻下则会形成癖积。如果是实食在体内，也可以攻下，攻下之后，补脾必能痊愈，根据虚实情况，无不有效。〔曾〕钱乙说：吐乳泻黄，是伤热乳，吐乳泻青，是伤冷乳，都应当攻下，这是迎夺的方法。不如伤热的用五苓散来引导逆气，伤冷的用理中汤来温中，自然平复。脾经积滞未除，再次被饮食所伤，不吐就泻，不泻就吐，适宜用三棱散化积，守胃散和中。

Baifu Wan (White Head Pill) [Indicated for: Phlegm-saliva]
Qian Yi stated: Vomiting and diarrhea with undigested milk indicate food injury; purgation is appropriate. The son of Feng Chengwu, aged five, suffered from vomiting, diarrhea, high fever, and loss of appetite. Qian Yi observed that his black pupil was small while the white sclera was prominent, and his complexion was pale. He said, "This child will surely suffer from frequent illnesses. A pale complexion indicates deficient Shen (Spirit); a small black pupil indicates Kidney deficiency. The black pupil corresponds to Water. Being inherently timid and deficient, he is prone to illness. Even if he grows up, his muscles will not be robust, he will not tolerate cold or heat, his condition will easily shift between deficiency and excess, and his Spleen and Stomach will also be weak. He must not indulge in alcohol; without proper care, he will not reach middle age. A face lacking spiritual luster resembles blood loss in women. Currently, vomiting, diarrhea, anorexia, and high fever indicate food injury. Furthermore, those with deficiency-timidity should not be purged. Purging causes pathogenic factors to enter the Lung causing cough, the Heart causing palpitations/fright, the Spleen causing diarrhea, and the Kidney exacerbating deficiency. It is better to use Xiaoji Wan (Eliminate Accumulation Pill) to grind down the accumulation, as there is only slight food retention. If the injury is severe, purgation can be used; otherwise, it may form a mass (Pi). If solid food remains internally, purgation is also applicable. After purging, tonifying the Spleen will lead to recovery. Following the principles of deficiency and excess, all cases will be effective. [Zeng] Qian Yi said: Vomiting milk with yellow stool indicates injury from hot milk; vomiting milk with green stool indicates injury from cold milk. Both require purgation, which is the method of 'attacking and seizing' (Yingduo). It is better to use Wuling San (Five-Ingredient Powder with Poria) for hot injuries to guide rebellious Qi downward, and Lizhong Tang (Regulate the Middle Decoction) for cold injuries to warm the interior, leading to natural recovery. If Spleen meridian stagnation is not cleared and the body is injured again by diet, resulting in vomiting or diarrhea, use Sanleng San (Curcuma Longa Powder) to resolve accumulation and Shouwei San (Stomach-Guarding Powder) to harmonize the Stomach.
