【名称】白符。
【产地】《图经本草》记载产于泰山之阴面。苏恭说产于慈州诸山，泰山左侧没有听说有出产。如今只有潞州有出产。潞州与慈州相近，此处所产也应可用。古代断下方剂中多用此药，如今医家也多使用。
【产地补充】《唐本注》云产于杭州余杭山，如今不再采集，而苏州现在进贡，但入药效果不甚佳。唯有延州山中出产的最为优良。从两块石头中间取出。延州每当被外族敌军围城时，若无水源，便挖掘深广三五丈的地坑，用石脂和蜜混合密封储存水，可使水长时间不渗漏。以此法取水者，认为最为良善。
【采收】无固定时节。
【鉴别】纹理细腻者为佳。
【质地】类似滑石，质地酥软。
【颜色】白色。
【味道】甘、酸。
【性质】缓收（收敛作用缓和）。
【气味】气薄，属阳中之阴。
【功效】固护肠胃，排出疮疡脓毒。
【配伍】燕屎为其使药。
【相反/相畏】畏惧黄芩、黄连、甘草、飞廉；厌恶松脂、马目毒公。
【治疗应用】《图经本草》记载：小儿脐中汁液流出不止，兼见红肿，用石脂末加热后敷贴脐部，每日三次，疗效良好。
【治疗应用】《药性论》云：涩大肠。
【治疗应用】《衍义》云：初生未满月的小儿多因啼叫导致脐中出血，用石脂末贴敷即可痊愈；若未愈，微炒过后放冷再贴，但仍不可剥揭伤口。
【合治方】与干姜等分捣碎，用百沸汤调和面粉制成糊状，揉匀制成梧桐子大小的丸剂，晒干。米饮送服三十丸，治疗久泻久痢不止；若病情较重，再加三十丸。另法：研取半两如粉，加入白粥中空腹服用，治疗小儿水痢，形体羸弱不能耐受汤药者，病可痊愈。

[Name] Baifu.
[Origin] *Tujing Bencao* states it grows on the north side of Mount Tai. Su Gong says it comes from the mountains of Cizhou; it is not heard that it grows on the left side of Mount Tai. Currently, it is only found in Luzhou Prefecture. Luzhou is close to Cizhou, so the local product should also be usable. It was frequently used in ancient formulas and is still widely used by physicians today.
[Origin Supplement] *Tangben Zhu* notes it comes from the mountains of Yuhang, Hangzhou, which are no longer harvested; Suzhou now offers it as tribute, but it is not very suitable for medicinal use. The best quality comes from the mountains of Yanzhou. It is extracted between two stones. In Yanzhou, when besieged by foreign enemies and lacking water, people dig pits three to five zhang deep and wide, sealing them with a mixture of earth lipid and honey to store water, which remains non-leaking for a long time. This method is considered optimal.

[Therapeutic Application] *Yaoxing Lun* states: Astringes the Large Intestine.
[Therapeutic Application] *Yanyi* states: Newborns under one month old often cry excessively, causing bleeding from the umbilicus. Applying Baishizhi powder cures it immediately. If not cured, lightly roast, cool down, and reapply, but do not peel off the wound.

Alternatively, grind half liang into powder, mix with white porridge, and take on an empty stomach to treat infantile watery diarrhea in emaciated children who cannot tolerate decoctions, leading to recovery.
