胡桃补肾，尽人知之，但多食亦能生虫，世人不识也。或谓胡桃杀虫，子反谓生虫，得
无误
耶？夫胡桃杀虫，乃胡桃之油者也。凡虫得油即死，故油胡桃杀虫。若胡桃未油者，乌能杀

山楂，味道甘甜且带辛味，气性平和，没有毒性。进入脾、胃两条经脉。能消除积存的食物，治疗产后瘀血引起的腹痛（儿枕痛），去除停滞的瘀血，调理疮疡，疏通郁结的气机，治疗疝气，健运脾胃，祛除腹部胀满如鼓的症状。煮肉时少量加入，很快就能使肉质变烂，因此特别擅长消化肉类食物。这是治疗各种肉食积滞必须使用的药物，作为辅助药使用效果很好。
有人问：山楂只擅长消化肉类，并治疗产后瘀血腹痛有神奇疗效，没听说它有其他功绩。回答说：山楂的功效，实际上不止这些。大致来说，消食理滞是它的长处，祛臌胀、疗疝则是它的短处。
有人怀疑山楂有功也有过，不能因为伤害肉食而一概不用它。回答说：山楂的功效，全在于消化肉类。如果让食用肉食积滞的人忌用山楂，又该用什么东西来化解呢？山楂的过失，在于过度消化肉类，从而损伤了脏腑的正气。然而，如果在补气、补血的方剂中使用山楂，不仅善于消化肉类，而且更善于行气利气。所以山楂的功与过，完全取决于使用是否有方法。
有人怀疑山楂的功过都很轻微，何必用危言耸听的话来告诫。回答说：山楂的功效虽然轻微，但用在气血旺盛、阳气健壮的人身上，确实不觉得它有害；但如果用在元气虚弱、血液衰少的人身上，确实会看到它造成伤害。
胡桃肉，味道甘甜，气性温热，没有毒性。进入肾经。滋润的特性能生精，涩敛的特性能固精，更能补益肾火，兼能乌黑须发，治愈石淋，是温补命门的药物，不必配合破故纸（补骨脂）才能治愈腰痛。尤其善于平息上逆之气，与人参、熟地黄、山药、麦冬、牛膝等药物配合，定喘效果神奇。世人只知道它是食物，而不知道将其用于补益药剂中，其功效更加奇妙。
人们都知道胡桃补肾，但多吃也能生虫，世人并不知晓。有人说胡桃杀虫，我却说它生虫，难道错了吗？胡桃杀虫，是因为胡桃油的作用。凡是虫子遇到油就会死亡，所以油胡桃能杀虫。如果胡桃没有油，怎么能杀虫呢？古人取胡桃加硼砂，用来治疗痞块瘕聚，并不是为了杀虫，而是利用它将药力引入下焦至阴的部位。如果与补药同时施用，就不会生虫，反而能获得巨大的益处。
Shanzha (Crataegi Fructus), with a sweet and pungent taste, neutral qi, and non-toxic nature. It enters the Spleen and Stomach meridians. It eliminates retained food, treats postpartum abdominal pain due to blood stasis (Erzhen Tong), removes stagnant blood, regulates sores and ulcers, moves Qi stagnation, treats hernia, strengthens the Spleen and Stomach, and dispels abdominal distension resembling drum鼓 (Guzhang). When added in small amounts to boiling meat, it softens the meat quickly; thus, it is particularly effective in digesting meat. It is an essential herb for treating various types of meat indigestion and serves well as an adjuvant or guiding drug.
One might ask: Shanzha only digests meat and is miraculously effective for postpartum abdominal pain; its other merits are unheard of. The response is: Shanzha's functions are not limited to this. Generally, resolving food retention and regulating stagnation are its strengths, while dispelling abdominal distension and treating hernia are its weaknesses.
Some doubt that since Shanzha has both merits and faults, it should not be universally used just because it may harm those with meat accumulation. The response is: Shanzha's merit lies entirely in digesting meat. If those suffering from meat accumulation were forbidden from using it, what else could resolve it? Shanzha's fault lies in over-digesting meat, thereby damaging the Qi of the Zang-Fu organs. However, when used within formulas for tonifying Qi and Blood, it not only excels at digesting meat but also effectively promotes the flow of Qi. Thus, the merit and fault of Shanzha depend entirely on whether it is used correctly.
Some question why such grave warnings are necessary if Shanzha's effects are minor. The response is: Although Shanzha's effect is mild, it causes no harm when used in individuals with robust Qi and strong Yang. However, when used in individuals with deficient Qi and depleted Blood, it can indeed cause damage.
Hutaorou (Juglandis Semen), with a sweet taste and warm qi, is non-toxic. It enters the Kidney meridian. Its moistening property generates Essence, and its astringent property secures Essence. It further benefits Kidney Fire, darkens beard and hair, cures Stone Lin (Shi Lin), and is a warming and tonifying herb for the Mingmen (Gate of Life). It does not necessarily require supplementation with Pogostemonis Herba (Pogu Zhi) to cure lower back pain. It is especially good at calming rebellious Qi. When combined with herbs like Ginseng Radix et Rhizoma (Renshen), Rehmanniae Radix Praeparata (Shudihuang), Dioscoreae Rhizoma (Shanyao), Ophiopogonis Radix (Maidong), and Achyranthis Bidentatae Radix (Niuxi), its ability to calm wheezing is miraculous. People generally know it only as food and do not realize its efficacy when included in tonic prescriptions, where its success is even more remarkable.
Everyone knows Hutaorou tonifies the Kidneys, but excessive consumption can lead to worm infestation, a fact unknown to the public. Some claim Hutaorou kills worms, yet I say it generates them; is this not an error? Hutaorou kills worms due to its oil content. Any worm coming into contact with oil dies; therefore, oily Hutaorou kills worms. If Hutaorou lacks oil, how can it kill worms? Ancients used Hutaorou with Borax to treat epigastric masses (Pi Jia), not for killing worms, but to guide the medicine to the deepest Yin regions of the Lower Jiao. When administered together with tonic drugs, it will not generate worms and instead provides significant benefit.
