蜀人多种菊以苗可以菜花可以药园圃悉能植之 中买为不可郊野之人多采野菊供药肆
颇有大误真菊延龄野菊泻人如张华言黄精益寿钩吻杀人如此类也(牧竖闲谈)
舒州医人李惟熙善论物理云菱芡皆水物菱寒而芡暖者菱花开背日芡花开向日故也又曰桃
杏双
仁辄杀人者其花本五出六出必双草木花皆五出唯栀子雪花六出此殆阴阳之理今桃杏六出双仁
皆杀人者失常故也
上药养命谓五石炼形六芝延年也中药养性谓合欢蠲忿萱草忘忧也下药除病谓大黄除实当
归止痛也(博物志)

黄仙君的口诀中规定，服用丹药时不应食用大蒜、石榴籽、猪肝和狗头肉。
蜀地人广泛种植菊花，其嫩苗可作为蔬菜，花朵可入药，园林中都能栽培。但有人购买菊花却分辨不清，郊野之人多采摘野菊供应药店，这造成了很大的误解。真正的菊花能延年益寿，而野菊则耗损人体元气，正如张华所说：“黄精能益寿，钩吻能杀人”，道理是一样的。（出自《牧竖闲谈》）
舒州的医生李惟熙善于论述事物的物理规律，他说：菱角和芡实都是水生植物，菱角性寒而芡实性暖，这是因为菱角的花背向太阳开放，而芡实的花面向太阳开放。他又说：桃仁和杏仁如果是双仁的就会致人死亡，因为桃花本来有五个花瓣，如果有六个花瓣，结出的果实往往会有双仁。草木的花通常都是五瓣，只有栀子和雪花花是六瓣。这大概是阴阳的道理。如今桃杏如果开出六瓣花并结出双仁，就违背了常理，所以会致人死亡。（出自《牧竖闲谈》）
韩众服用菖蒲十三年，身上长出了毛发，石头上有一寸长的九节紫花菖蒲，这种品质最好。（出自《抱朴子》）
服用丹药的人忌讳吃羊血，即使服药几十年，只要吃一次羊血，之前的功夫都会白费。
上等的药物用于保养生命，指的是五石散炼形、六芝延年；中等的药物用于调养性情，指的是合欢树消除愤怒、萱草忘记忧愁；下等的药物用于祛除疾病，指的是大黄攻逐实邪、当归缓解疼痛。（出自《博物志》）
将朴硝研成细末，每次取二钱，用温热的童子尿调服。洪州进贤县的曾通仕讲述：他过去担任丰城县尉时，家里有一只怀孕的猫生下一只小猫后，其余四只死在腹中，导致腹部肿胀、哀鸣欲绝。他试着问医生，医生建议用此药灌服，死胎随即排出，猫得以存活。后来有一头牛也出现类似情况，用这个方法也救活了。医生说这是原本治疗人的方子，用来治牲畜也有效，后来再用于治疗人，没有不灵验的。（出自《信效方》）
夏文庄公性格豪放奢侈，天赋异于常人，睡觉时身体冷得像僵死一样，如同去世的人，醒来后必须让人温暖很久才能活动。有人看见他坐着马车，车上装载着一个巨大的物体，询问才知道是用几千两绵絮做的绵帐。他常年服用仙茅、钟乳石、硫黄等热性药物，数量多得无法计算。早晨每餐都喝钟乳粥，有个小吏偷吃了一些，结果毒疮发作，几乎无法救治。（出自《笔谈》）
The precepts of Immortal Huang stipulate that when taking elixirs, one should not consume garlic, pomegranate seeds, pig liver, or dog head meat.
People in Shu widely cultivate chrysanthemums; their tender shoots can be used as vegetables, and flowers for medicine, which can be planted in gardens. However, some purchasers cannot distinguish them well; people in the suburbs often pick wild chrysanthemums to supply pharmacies, causing significant errors. True chrysanthemum prolongs life, whereas wild chrysanthemum drains the body's vitality. As Zhang Hua stated: "Polygonatum (Huangjing) benefits longevity, while Aconitum (Gouwen) kills." The principle is similar. (From *Mu Shu Xian Tan*)
Li Weixi, a physician from Shuzhou, was skilled in discussing the physical principles of things. He said: Both water caltrop (Lingjiao) and Chinese water chestnut (Qianshi) are aquatic plants. Water caltrop is cold in nature, while Chinese water chestnut is warm, because the flower of the water caltrop faces away from the sun, whereas the flower of the Chinese water chestnut faces the sun. He also said: Peach kernels and apricot kernels that are double-lobed will kill people. This is because peach blossoms originally have five petals; if there are six petals, the fruit often has double kernels. Most plant flowers have five petals, except for Gardenia (Zhizi) and Snowdrop (Xuehua), which have six. This likely relates to the principles of Yin and Yang. Now, if peach or apricot trees bloom with six petals and produce double kernels, it deviates from the norm, thus becoming lethal. (From *Mu Shu Xian Tan*)
Han Zhong took Rhizoma Acori Tatarinowii (Changpu) for thirteen years, and hair grew on his body. On rocks, nine-jointed purple-flowered Changpu is considered superior. (From *Baopuzi*)
Those who take elixirs must avoid eating sheep blood. Even after decades of medication, a single consumption of sheep blood will render all previous efforts futile.
Superior drugs nourish life, referring to the Five Minerals (Wushi) refining the form and the Six Mushrooms (Lingzhi) extending years. Medium drugs nourish temperament, referring to Albizia Julibrissin (Hehuan) dispelling anger and Daylily (Xuancacao) forgetting sorrow. Inferior drugs eliminate disease, referring to Radix et Rhizoma Rhei (Dahuang) purging excess and Angelica Sinensis (Danggui) relieving pain. (From *Bowuzhi*)
Pumex (Piaoxiao) is ground into a fine powder. Two qian are taken, mixed with warm urine from an uncircumcised boy. Zeng Tongshi from Jinxiang, Hongzhou, recounted: When he served as Magistrate of Fengcheng, a cat in his home gave birth to one kitten while four others died in the womb, causing abdominal distension and agonizing cries. He consulted a doctor, who advised administering this medicine. The dead fetuses were expelled, and the cat survived. Later, a cow presented with similar symptoms and was also saved by this method. The doctor stated that although this was originally a human prescription, it was effective for animals. Subsequently, its use in humans proved invariably effective. (From *Xinxiao Fang*)
Duke Xia Wenzhuang had a lavish disposition and unique constitution. During sleep, his body became cold as if stiff, resembling a corpse; upon waking, he required warming for a long time before he could move. Someone saw him traveling in a carriage loaded with a large object, which turned out to be a cotton curtain made of thousands of taels of cotton wadding. He frequently consumed hot medicines such as Rhizoma Curculiginis (Xianmao), Sulfur (Liuhuang), and Concha Ostreae (Zhongru) in unquantifiable amounts. Every morning he ate congee with Ostracoderm (Zhongru). A minor official stole some and subsequently developed a severe carbuncle, nearly dying from toxicity. (From *Bitan*)
