甘涩温有毒。
《本经》主腹中邪气，去三虫，蛇螫蛊毒，鬼疰伏尸。
发明 榧实，肺家果也。性温散气，故能去腹中邪气。三虫诸疾，火炒食之。引火入肺
，多食则大肠受伤。小儿黄瘦有虫积者宜食，与使君子同功。观《本经》主治可知。
甘温无毒。
发明 海松子甘温益肺清心，止嗽润肠，兼柏仁、麻仁之功，温中益阴之效。心肺燥痰
干咳之良药也。
苦辛温无毒。
发明 槟榔泄胸中至高之气，使之下行；性如铁石之沉重，能坠诸药至于下极。故治冲
脉为病，逆气里急，及治诸气壅腹胀后重如神。胸腹虫食积滞作痛，同木香为必用之药。其
功专于下气消胀，逐水除痰，杀虫治痢，攻食破积，止疟疗疝，香港脚瘴疠。若气虚下陷人及
膈上有稠痰结气者得之，其痞满昏塞愈甚。又凡泻后、疟后、虚痢切不可用也。闽广瘴毒之
乡人常食此，必以 叶裹嚼之。所云饱能使之饥，醉能使之醒者，以其能下气也。云饥能使
之饱，醒能使之醉者，以 叶辛温能开发中外之气，以散瘴疠之邪也。
即大腹槟榔
辛涩温无毒。此味与槟榔皆性坚难切，须用滚水泡渍切之。若以
水浸浊满，不但失其性味，反有伤于胃气也。
发明 大腹子偏入气分，体丰湿盛者宜之。夫槟榔偏主血分，腹满多火者宜之。时珍谓
大腹与槟榔同功，似未体此。
【榧子】
味甘、涩，性温，有毒。
《神农本草经》记载其主治腹中邪气，驱除三虫（蛔虫、蛲虫、寸白虫），治疗蛇咬伤及蛊毒、鬼疰（一种慢性消耗性传染病）和伏尸（潜伏体内的恶疾）。
【发明】
榧实是肺脏的果实。其性温而能散气，因此能够去除腹中的邪气。对于三虫引起的疾病，将榧子火炒后食用。若引火入肺，多食则会损伤大肠。小儿因虫积导致面色萎黄消瘦者适宜食用，功效与使君子相同。从《神农本草经》的主治功能即可看出这一点。
【海松子】
味甘，性温，无毒。
【发明】
海松子味甘性温，能补益肺气、清心火，具有止咳、润肠的功效，兼具柏子仁、火麻仁的作用，以及温中、滋阴的效果。它是治疗心肺燥热、痰多、干咳的良药。
【大腹子】
味苦、辛，性温，无毒。
【发明】
槟榔能疏泄胸中至高之气，使其下行；其质地如铁石般沉重，能使其他药物作用到达身体最下部。因此，它治疗冲脉病变引起的逆气上冲、腹部拘急疼痛，以及治疗各种气机壅滞导致的腹胀、里急后重等症状效果神妙。对于胸腹部因虫积或食积停滞引起的疼痛，常与木香配合使用，是必用的药物。其功效专于下气消胀，逐水除痰，杀虫止痢，攻积破滞，治疗疟疾和疝气，以及脚气和瘴气。如果是气虚下陷之人，或者膈上有稠痰结气的人服用，会导致痞满昏塞的症状更加严重。此外，凡是腹泻之后、疟疾之后、虚寒性痢疾，都绝对不可使用。闽广地区瘴毒之乡的人经常食用此物，必定用叶包裹咀嚼。所谓“饱食后吃它能使人感到饥饿，醉酒吃它能使人清醒”，是因为它能下气。所谓“饥饿时吃它能使人感到饱足，清醒时吃它能使人醉倒”，是因为叶味辛温，能开发内外之气，以消散瘴疠之邪。
即大腹槟榔
味辛、涩，性温，无毒。这种药材与槟榔一样质地坚硬难以切片，必须用滚水泡浸后再切。如果用水浸泡过久导致水分浑浊充满其中，不仅会失去其原有的性味，反而会损伤胃气。
【发明】
大腹子偏入气分，体质丰腴湿气盛者适宜使用。而槟榔偏主血分，腹部胀满且多火者适宜使用。李时珍认为大腹子与槟榔功效相同，似乎没有体察到其中的区别。
[Feizi (Torreya Seed)]
Sweet, astringent, warm, toxic.
*Shennong Bencao Jing* states it treats evil qi in the abdomen, expels the three parasites (roundworms, pinworms, and tapeworms), snakebites, gu poison, guizhu (a chronic wasting infectious disease), and fushi (latent malignant diseases).
[Invention]
Torreya seeds are fruits of the lung organ. Their nature is warm and dispersing to qi, thus they can remove evil qi from the abdomen. For diseases caused by the three parasites, roast them over fire and eat them. If fire is drawn into the lungs, excessive consumption will damage the large intestine. It is suitable for children with yellowish complexion and emaciation due to parasite accumulation; its efficacy is similar to that of *Shijunzi* (Quisqualis Fruit). This can be understood from the indications in *Shennong Bencao Jing*.
[Haisongzi (Pinus Massoniana Seed)]
Sweet, warm, non-toxic.
[Invention]
*Haisongzi* is sweet and warm, benefiting the lung qi and clearing the heart fire. It stops coughing and moistens the intestines, possessing the functions of *Bairen* (Platycladi Semen) and *Maren* (Cannabis Seed), as well as the effects of warming the middle and nourishing yin. It is an excellent medicine for dry coughs caused by dryness-heat phlegm in the heart and lungs.
[Dafuzi (Areca Seed / Betel Nut)]
Bitter, pungent, warm, non-toxic.
[Invention]
*Binglang* (Areca Seed) drains the highest qi in the chest, causing it to descend downward; its nature is heavy like iron or stone, capable of driving other herbs to the lowest extremities of the body. Therefore, it treats disorders of the Chong vessel characterized by rebellious qi and abdominal urgency, and is miraculous in treating various conditions of qi stagnation leading to abdominal distension and tenesmus. For pain in the chest and abdomen caused by parasite or food retention, it is used together with *Muxiang* (Aucklandiae Radix) as an essential herb. Its function specializes in descending qi and reducing distension, expelling water and resolving phlegm, killing parasites and treating dysentery, attacking accumulation and breaking stagnation, stopping malaria and treating hernia, as well as treating hongjiao (podagra/elephantiasis) and zhangli (miasma). However, if taken by individuals with qi deficiency and sinking, or those with thick phlegm and stagnant qi above the diaphragm, their symptoms of fullness and obstruction will worsen. Furthermore, it must absolutely not be used after diarrhea, after malaria, or in cases of deficient cold dysentery. People in the miasma-poison regions of Min and Guang often consume this, usually chewing it wrapped in leaves. The saying "eating it when full makes one feel hungry, eating it when drunk makes one sober" is because it descends qi. The saying "eating it when hungry makes one feel full, eating it when sober makes one drunk" is because the leaves are pungent and warm, capable of opening up internal and external qi to dissipate miasma pathogens.
Namely Dafu Binglang
Pungent, astringent, warm, non-toxic. This substance, like *Binglang*, has a hard texture difficult to slice, requiring soaking in boiling water before cutting. If soaked in water until it becomes turbid and swollen, it not only loses its original properties and flavor but also damages stomach qi.
[Invention]
*Dafuzi* tends to enter the qi level, making it suitable for those with abundant physique and excess dampness. In contrast, *Binglang* primarily governs the blood level, making it suitable for those with abdominal fullness and excess heat. Li Shizhen stated that *Dafu* and *Binglang* have the same efficacy, which seems to fail to grasp this distinction.
