【郁李仁】
味酸，性平，无毒，归入大肠经。主治四肢浮肿，肠中气机阻滞，关格不通（指大小便闭塞不通的危重病证），膀胱拘急疼痛，能润肠通便、破散瘀血，利水下行、降逆下气，消食导滞、宽中和胃。忌与面食及牛、马、驴肉同食。
按语：郁李仁属阴，药性主沉降，因此独入大肠经。然而其宣泄作用过强，容易耗散五脏的真气，体虚之人不宜多用。
【芜荑】
味辛，性温，无毒，归入肺、脾二经。主治五脏内的邪气，肠风痔漏（肠道出血或痔疮漏管），疥癣及风热之症，皮肤骨节间的风湿痹痛，能驱除冷气，化解陈积食物，消除疳积（小儿营养不良综合征），杀灭各种寄生虫。使用时需去除外皮，用面粉炒至黄色后使用。
按语：芜荑之辛味适宜于肺，温性适宜于脾，因此同时归入这两经。对于风寒湿邪困脾、大肠冷滑泄泻者，此药是关键药剂。凡是气滞和食积都因寒邪而停滞，各种寄生虫都因湿气而生，得到芜荑以温燥之法治疗，如果病证还不能痊愈，是从来没有的事。
【五加皮】
味辛苦，性温，无毒，归入肺、肾二经。主治心腹腰膝疼痛，疝气，骨节拘挛多年不愈，皮肤下的瘀血，阳痿及阴囊潮湿，小儿下肢软弱无力，女子外阴瘙痒及腐蚀溃烂，补益劳伤，坚固关节骨骼，益智益气、填补精髓，长期服用可延年益寿。以远志为引经药，畏蛇皮、玄参。
按语：五加皮辛味能泻肺气，苦味能坚补肾气，适宜并入这两经的治疗中。心腹等部位的病症，哪不是肺肾两经所主的证候，却没有治不好的呢？古人关于延年的说法，这就是证据了。
雷公说：现在的五加皮，其树干原本是白色的，秋季树上叶子像蒲草叶一样，三片叶子的花是雄花，五片叶子的花是雌花，剥取树皮……（原文此处中断）
【楮实】
味甘，性平，无毒，归入肾经。主治补益虚劳，壮阳起痿，辅助腰膝，消退水肿，坚固筋骨，益气力，充盈肌肤，美容颜，使耳目聪明。长期服用可长生不老，需用酒浸泡一夜后蒸制使用。树汁可涂抹治疗癣疾及蝎子螫伤。树皮主治逐水利尿。叶子主治小儿发热，煎汤外洗恶疮，促进肌肉生长。茎主治瘾疹瘙痒，单独煮水洗浴。
按语：楮实浊阴之气下降，适宜入少阴肾经，其补益功效在各类医书中均有记载。唯独《修真秘旨》中说：服用楮实的人，往往会得骨软病，这并非没有根据的说法，但很难解释，暂且记录下来以待明智之人考证。
雷公说：凡是用楮实，采得之后，用水浸泡三天，用物体搅动旋转，浮在水面上的去掉，然后晒干，再用酒浸泡一个时辰（十二小时），从巳时到亥时蒸制，焙干后使用。
[Prunus japonica Seed (Yuli Ren)]
Taste: Sour. Nature: Neutral. Non-toxic. Meridian Tropism: Large Intestine Channel. Indications: Mainly treats edema of the four limbs, stagnation of Qi in the intestines, Guan Ge syndrome (a critical condition characterized by obstruction of both urination and defecation), urgency and pain in the bladder. It moistens the intestines to promote bowel movement, breaks up blood stasis, promotes diuresis to direct water downward, directs rebellious Qi downward, aids digestion, relieves fullness, and harmonizes the middle Jiao. Contraindications: Avoid consuming with wheat products and meat from cattle, horses, or donkeys.
Commentary: Prunus japonica Seed is Yin in nature and its action is primarily descending; therefore, it enters the Large Intestine channel exclusively. However, its purgative and draining action is too strong and can disperse the True Qi of the five Zang organs; thus, it should not be used in excess by patients with deficiency.
[Archidendron Biglandulosum Fruit (Wuyi)]
Taste: Pungent. Nature: Warm. Non-toxic. Meridian Tropism: Lung and Spleen Channels. Indications: Mainly treats pathogenic factors within the five Zang organs, intestinal wind with hemorrhoids and fistulas, scabies, tinea, and wind-heat conditions, wind-dampness bi-syndrome between the skin and bone joints. It dispels cold qi, transforms retained food, eliminates childhood malnutrition syndromes (Gan accumulation), and kills various parasites. Preparation: Remove the husk, stir-fry with flour until yellow before use.
Commentary: The pungency of Archidendron Biglandulosum Fruit suits the Lung, and its warmth suits the Spleen; hence, it enters both channels. For cases where wind-cold-dampness encumbers the Spleen or there is cold slipperiness of the Large Intestine, this herb is a crucial agent. Since both Qi stagnation and food retention are caused by cold leading to stagnation, and all parasites are generated by dampness, obtaining Archidendron Biglandulosum Fruit to warm and dry the pathogen ensures that if the condition still does not resolve, such a case has never existed.
[Acanthopanax Senticosus Bark (Wujia Pi)]
Taste: Pungent and Bitter. Nature: Warm. Non-toxic. Meridian Tropism: Lung and Kidney Channels. Indications: Mainly treats pain in the heart, abdomen, waist, and knees; hernia; chronic joint stiffness and spasms; blood stasis under the skin; impotence and dampness of the scrotum; weakness of the lower limbs in children; itching and erosion of the female external genitalia; tonifies labor injuries; strengthens joints and bones; benefits willpower and Qi; replenishes essence and marrow; long-term use extends longevity. Herb Compatibility: Use Polygala Root (Yuanzhi) as a guiding herb; adverse reaction with Snake Skin and Scrophularia Root (Xuanshen).
Commentary: Acanthopanax Senticosus Bark's pungency can drain Lung Qi, and its bitterness can strengthen Kidney Qi; it is suitable for inclusion in treatments targeting these two channels. How could conditions such as those in the heart and abdomen, which are manifestations of these two channels, remain untreatable? The ancients' claims regarding life extension are evidenced by this.
Lei Gong stated: Regarding current Acanthopanax Senticosus Bark, the tree trunk is originally white. In autumn, the leaves resemble cattail leaves. Flowers with three leaflets are male, and flowers with five leaflets are female. Peel the bark... [Text cuts off here]
[Celtis Sinensis Fruit (Chushi)]
Taste: Sweet. Nature: Neutral. Non-toxic. Meridian Tropism: Kidney Channel. Indications: Mainly tonifies deficiency and fatigue, strengthens yang and treats impotence, assists the waist and knees, reduces edema, strengthens sinews and bones, boosts Qi and strength, plumps the skin, beautifies complexion, and clarifies the eyes and ears. Long-term use promotes longevity. Preparation: Soak in wine overnight, then steam. Tree sap: Apply topically for tinea and scorpion stings. Bark: Promotes diuresis and water metabolism. Leaves: Treat fever in children; decoct for washing severe sores to promote muscle growth. Stem: Treats urticaria with itching; boil alone for bathing.
Commentary: Celtis Sinensis Fruit has a turbid Yin nature that descends, making it suitable for entering the Shaoyin (Kidney) channel. Its tonifying effects are recorded in various texts. However, *Xiuzhen Mizhi* states that those who consume Celtis Sinensis Fruit often develop soft-bone disease; this is not an unfounded claim, but it is difficult to explain. It is recorded here for future scholars to investigate.
Lei Gong stated: When using Celtis Sinensis Fruit, after harvesting, soak it in water for three days. Stir vigorously; discard any material floating on the surface. Then sun-dry it. Subsequently, soak it in wine for one shichen (12 hours), steam it from Si hour (09:00-11:00) to Hai hour (21:00-23:00), and bake until dry before use.
