楝实（楝树的果实）禀受天的阴气，得地之苦味，所以味道极苦，性质寒凉，有小毒。归入足阳明、手太阴、足太阴经。凭借苦寒的药性，能够清除温病高热狂躁，有利水消肿和杀虫的功效。如果脾胃虚弱或虚寒者应当忌用。
楝实即金铃子。去掉果皮后选取果肉，主治温病伤寒，大热烦躁狂乱，调理膀胱和小肠的疝气牵引疼痛，通利小便水道，杀灭三虫及疥疮。樗树根有雌雄之分：雄根呈红色，不结果实，毒性极大，忌用于煎煮；雌根呈白色，果实较多，毒性轻微可以采集，以向东生长的为佳。使用时去掉青色部分保留白色部分，单味药煎酒服用，在上半月服用，能大大杀灭寄生虫，虫体多时会结成团块排出体外，皮肤上的虫疮逐个推除，积聚消散、行气止痛，研碎外敷可治疗瘙痒性虫疮。
椿根白皮（香椿树皮的内层），禀受地中的阴气而生，所以味道苦、涩，微寒，有毒。归入手阳明、足阳明经。凭借苦寒的药性，外用清洗疮疥风疽，去除口鼻部位的疳虫疥疮。且苦能燥湿，寒能清热，涩能收敛，因此能去除肠胃一切湿热引起的蛔虫、崩漏、痢疾，与樗树皮功用相同。但樗树根叶效果更好。凡是采集时不使用向西生长的，采得后用布袋盛装，储存在阴凉处干燥，去掉粗皮，用蜂蜜炙烤后使用。
樗根白皮（臭椿树皮的内层），即臭椿树皮，主治清洗疮疥风疽，去除口鼻疳虫疥疮。止住女子月经量过多，久痢带下、崩中漏下，男子夜间梦遗精滑、肠风痔漏，缩小尿量，驱除蛔虫。椿白皮，即香椿树皮，取白色部分为佳，主治疳积，止血功效相同，妇科常用。只能制成丸剂散剂，不能放入汤剂煎煮。但是腹泻由脾胃虚寒引起，崩漏滞下由真阴不足，以及痢疾积气未尽者，这两种情况都不可使用。
络阳有一位妇人，贪饮酒类无度，多吃鱼蟹，毒素蓄积在脏腑，日夜排便二三十次，大便脓血混杂而下，大肠连带肛门疼痛难以忍受。用止血痢药无效，用治肠风药则病情加重，因为肠风证只有血没有脓。如此半年，气血逐渐虚弱，食欲减退肌肉消瘦，服用热药腹部更痛、出血更多；服用冷药则导致泄泻、食欲减少；服用温平药则病无好转。这样过了一年，命悬一线等待死亡，有人教服人参散，一服药见效，二服药减轻，三服药脓血皆定，于是常服而痊愈。该方治疗夹热下痢，脓血疼痛严重，多日不愈，用樗根白皮一两，人参一两研为末，每次服用二钱，空腹用米汤调服。忌食油腻、湿面、青菜、果子、甜食、鸡、猪、鱼、羊、蒜、薤等食物。
Lianshi (Fructus Meliae) inherits the Yin Qi of Heaven and obtains the bitter flavor from Earth; thus, its taste is extremely bitter, its nature is cold, and it has slight toxicity. It enters the Foot-Yangming, Hand-Taiyin, and Foot-Taiyin meridians. Relying on its bitter-cold nature, it can eliminate febrile diseases with high fever and mania, promote diuresis, and kill parasites. It is contraindicated for those with Spleen-Stomach deficiency or cold.
Lianshi is also known as Jinlingzi (Semen Toosendan). After removing the peel and selecting the flesh, it treats febrile diseases and Shanghan (Cold Damage), severe heat with restlessness and mania, regulates hernia pain radiating from the Bladder and Small Intestine, promotes urination through the urinary pathways, and kills "Three Worms" (parasites) and scabies. The root of the Chutree (Toona sinensis) has male and female varieties: Male roots are red, bear no fruit, have great toxicity, and are forbidden for decoction; Female roots are white, bear more fruit, have slight toxicity and can be harvested; those growing towards the East are preferred. When used, remove the green part and retain the white part. Decocted alone in wine and taken during the first half of the lunar month, it greatly kills parasites. If there are many parasites, they form clumps and are expelled downward; skin sores caused by insects are pushed out one by one. When ground and applied externally, it treats itching insect sores.
Note: The bitter-cold nature is suitable for killing parasites, but it is prohibited for those with Spleen-Stomach deficiency-cold.
Chungen Baipi (Cortex Toonae), born from the Yin Qi within the Earth, tastes bitter and astringent, is slightly cold, and has toxicity. It enters the Hand-Yangming and Foot-Yangming meridians. Relying on its bitter-cold nature, when washed externally, it treats sores, scabies, wind-ju (fungal infections), and removes gnawing worms and scabies from the mouth and nose. Furthermore, bitterness dries dampness, cold clears heat, and astringency consolidates; thus, it eliminates all damp-heat in the Stomach and Intestines causing roundworms, metrorrhagia, and dysentery. Its function is identical to that of Chupi (Bark of Chutree). However, Chutree root and leaves are superior. When harvesting, do not use those growing towards the West. After harvesting, store in a cloth bag, dry in a shaded place, remove the coarse bark, and use after honey-frying.
Chugen Baipi (Inner Bark of Chinaberry Tree), which is the inner bark of the Chinaberry tree, treats washing sores, scabies, and wind-ju, removes gnawing worms and scabies from the mouth and nose. It stops excessive menstruation in women, chronic dysentery with leukorrhea, metrorrhagia and uterine bleeding, nocturnal seminal emission and slippery discharge in men, intestinal wind, hemorrhoids, and fistulae; it reduces urine volume and expels roundworms. Chunbaipi (Inner Bark of Chinese Toon), which is the inner bark of the Chinese Toon tree, taking the white part is best. It treats gan accumulation (pediatric malnutrition syndrome), has the same hemostatic effect, and is commonly used in gynecology. It can only be made into pills and powders, not decocted in soups. However, if diarrhea is caused by Spleen-Stomach deficiency-cold, or if metrorrhagia/stagnation is due to True Yin insufficiency, or if dysenteric stagnation and qi retention are not yet exhausted, neither condition should use this herb.
A woman from Luoyang drank excessively without restraint and ate much fish and crab, accumulating toxins in the Zang organs. She had bowel movements twenty to thirty times day and night, passing pus and blood mixed together, with unbearable pain in the Large Intestine extending to the anus. Medications for stopping bloody dysentery were ineffective, and medications for intestinal wind worsened the condition, because intestinal wind presents with blood but no pus. This persisted for half a year, gradually weakening Qi and Blood, reducing appetite, and causing emaciation. Taking hot medicines increased abdominal pain and bleeding; taking cold medicines caused diarrhea and reduced appetite; taking warm-neutral medicines resulted in no improvement. After a full year, her life was hanging by a thread, waiting for death. Someone advised taking Renshen San (Ginseng Powder). After one dose, symptoms improved; after two doses, they decreased; after three doses, pus and blood stabilized. She continued taking it and recovered. This formula treats lower dysentery with heat, where pus, blood, and pain are severe and persist for many days. It uses one liang of Chugen Baipi and one liang of Renshen (Radix Ginseng), ground into powder. Take two qian per dose, mixed with rice water on an empty stomach. Avoid greasy foods, wet noodles, green vegetables, fruits, sweets, chicken, pork, fish, mutton, garlic, and shallots.
