得天地阴寒之气，故味甘、苦，微温，无毒。与天门冬形相类而用相仿，故名野天
门冬，但天门冬治肺热，此治肺寒为别也。《千金方》用百部熬膏，入蜜，不时取服，
可疗三十年嗽。《杨氏经验方》∶治遍身黄肿，取鲜百部，捣窨脐上，以糯米饭半升，
拌酒半合，盖在药上，以帛包住，一二日后口内有酒气，则水从小便出，肿自消矣。
百部，治久嗽传尸骨蒸，肺热上气，散热清痰，润肺下气，诚久嗽寒嗽之要药也。
更杀传尸痨虫，小儿疳热，寸白蛇虫。同秦艽为末，烧烟熏之，去风亦杀虫之一验也。
禀天地至阴之精，其味苦、咸寒而无毒。故能去热除疳。一云∶兼甘、平，无
毒。以其得土气之浓，盖诸毒遇土即解，故可善解诸毒。
蓝实余蓝俱不入药，入药惟用蓼蓝。秋采实，晒干微研碎，煎服。杀虫疰疫鬼恶
毒，驱五脏六腑热烦，益心力，填骨髓补虚，聪耳目，利关节，通窍。但虚寒人及久
泻者，并腹中觉冷者忌之。茎叶可作靛染青，生捣绞汁饮，散风热赤肿，愈疔肿金
疮，追鳖瘕胀痛，百药毒总解，诸恶疮并驱。《衍义》云∶蓝实水有木。能使散败之
血分诸经络，故解毒最效。又治小儿壮热成疳，妇人产后血晕，消赤眼暴发，止吐衄时
来，天行温疫热狂，并宜急取煎服。丹溪普济消毒饮中，加板兰根者，即此是也。其靛
花名为青黛，宜合丸散。小儿疳热，消 泻肝下毒，杀虫，收五脏郁火，消上膈痰火并
妙，更驱时疫头痛，敛伤寒赤斑。一切疳病，面黄鼻赤，毛焦唇焦，口舌生疮，皮肤
枯槁，壮热等症，神奏奇功。虽凉而不伤脾胃，故疳痢疳痨并臻神效。
百部：禀受天地阴寒之气，所以味道甘、苦，性微温，无毒。它与天门冬形状相似且功效相近，因此被称为“野天门冬”，但天门冬用于治疗肺热，而百部用于治疗肺寒，这是它们的区别所在。《千金方》使用百部熬制成膏，加入蜂蜜，随时取服，可以治疗长达三十年的咳嗽。《杨氏经验方》记载：治疗全身黄肿，取新鲜百部捣烂敷于肚脐上，用半升糯米饭拌入半合酒，覆盖在药物上面，用布包裹住，一两天后如果口中有酒气，那么水湿就会从小便排出，肿胀自然消除。百部能治疗久咳导致的传尸骨蒸（一种慢性消耗性疾病，表现为骨节蒸热）、肺热上气，具有散热清痰、润肺下气的功效，确实是治疗久咳和寒咳的重要药物。此外还能杀灭传尸痨虫、小儿疳热以及寸白虫、蛇虫等寄生虫。与秦艽一起研成粉末，燃烧烟雾熏蒸，既能祛风也能杀虫，这是一项有效的验证。
蓝实：禀受天地至阴的精气，味道苦、咸，性寒，无毒。因此能够清热除疳。另一种说法认为兼有甘味和平性，无毒。因为它得土气浓厚，大概各种毒物遇到土就能化解，所以善于解除各种毒素。
蓝实及其余部分的蓝草都不入药，入药只用蓼蓝。秋天采集果实，晒干后轻微研碎，煎汤服用。能杀灭疰疫鬼恶毒，驱散五脏六腑的热烦，增强心力，填补骨髓补虚损，使耳目聪明，利关节，通窍道。但是体质虚寒的人、长期腹泻的人以及感觉腹中寒冷的人忌用。茎叶可以用来制作靛蓝染料，生捣绞汁饮用，能疏散风热引起的红肿，治愈疔疮和金创（金属利器造成的创伤），消退鳖瘕（腹部结块）胀痛，解百药毒，驱除各种恶疮。《衍义》说：蓝实水性属木。能使消散败血分布到各经络，所以解毒效果最好。又治疗小儿壮热发展成疳证，妇人产后血晕，消除暴发性赤眼，止住吐血衄血时常发作，天行温疫热狂，都应当紧急取来煎服。丹溪的普济消毒饮中，加入板兰根的，就是指的这个。它的靛花叫做青黛，适合配合做成丸剂或散剂。对于小儿疳热，能泻肝下毒，杀虫，收敛五脏郁火，消除上膈痰火，都非常奇妙，还能驱除时疫头痛，收敛伤寒引起的赤斑。一切疳病，如面色发黄、鼻头红赤、毛发焦枯、嘴唇焦裂、口舌生疮、皮肤干枯槁瘦、壮热等症状，都能神奇地奏效。虽然性凉但不损伤脾胃，所以对于疳痢、疳痨都能达到神效。
**Bai Bu (Stemona Root):** It inherits the Yin-cold Qi of Heaven and Earth; therefore, its taste is sweet and bitter, its nature is slightly warm, and it is non-toxic. Its shape resembles Tian Men Dong (Asparagus Root) and its usage is similar, hence it is named Ye Tian Men Dong (Wild Asparagus Root). However, while Tian Men Dong treats Lung Heat, Bai Bu treats Lung Cold, which is the distinction between them. *Qian Jin Fang* (Essential Prescriptions Worth a Thousand Gold) uses Bai Bu boiled into an ointment/paste, mixed with honey, taken as needed, which can treat chronic cough lasting thirty years. *Yang Shi Jing Yan Fang* (Experienced Formulas by Master Yang): To treat generalized yellow edema, take fresh Bai Bu, pound it into a paste, apply it to the umbilicus, cover it with half a sheng of glutinous rice mixed with half a he of wine, wrap tightly with cloth. After one or two days, if there is a smell of wine in the mouth, the water retention will discharge through urination, and the swelling will subside naturally. Bai Bu treats chronic coughs progressing to Chuan Shi Gu Zheng (a consumptive disease characterized by bone-steaming fever), Lung heat with rebellious Qi, dissipates heat, clears phlegm, moistens the Lung, and directs Qi downward. It is indeed a crucial herb for treating chronic and cold-type coughs. Furthermore, it kills Chuan Shi Lao Chong (tubercle bacilli/parasites causing consumption), Xiao Er Gan Re (pediatric malnutrition with heat), Cun Bai She Chong (tapeworms and other parasites). Mixed with Qin Jiao (Gentian Root) into powder and smoked, it expels Wind and kills parasites, which is a verified efficacy.
**Lan Shi (Isatis Seed):** It inherits the essence of extreme Yin from Heaven and Earth. Its taste is bitter and salty, its nature is cold, and it is non-toxic. Therefore, it can clear heat and eliminate Gan syndrome (malnutrition in children). Another view states it also has a sweet taste and neutral nature, non-toxic. Because it absorbs rich Earth Qi, and various toxins are resolved upon contact with Earth, it is excellent at resolving various poisons.
The seeds of Lan (Isatis) and other parts of the plant are generally not used in medicine; only Liao Lan (Polygonum Tinctorium) is used medicinally. The fruits are harvested in autumn, dried, slightly crushed, and decocted for oral administration. It kills Zhu Yi Gui E Du (pestilential pathogens and evil toxins), drives away heat and vexation from the Five Zang and Six Fu organs, strengthens heart power, fills the marrow, tonifies deficiency, brightens the ears and eyes, benefits the joints, and opens the orifices. However, it is contraindicated for those with deficiency-cold constitution, chronic diarrhea, or a sensation of cold in the abdomen. The stems and leaves can be used to make indigo dye. Freshly pounded and juiced, drinking the juice disperses Wind-Heat causing redness and swelling, heals Ding Zhong (carbuncles/furuncles) and Jin Chuang (metal weapon injuries), resolves Bie Zha (abdominal masses) and distension/pain, resolves all drug poisons, and drives away all malignant sores. *Yan Yi* (Expanded Meaning) states: Lan Shi's water element belongs to Wood. It allows dissipated and stagnant blood to distribute through the meridians, thus making its detoxification effect most potent. It also treats pediatric vigorous fever developing into Gan syndrome, postpartum blood fainting in women, acute red eye outbreaks, stops frequent epistaxis and hematemesis, and is suitable for urgent decoction for Tian Xing Wen Yi Re Kuang (epidemic febrile diseases with mania). In Dan Xi's Pu Ji Xiao Du Yin (Universal Benefit Decoction for Detoxification), Ban Lan Gen (Isatis Root) added refers to this. Its indigo flower is called Qing Dai (Indigo Naturalis), suitable for forming pills and powders. For pediatric Gan heat, it drains Liver and descends toxicity, kills parasites, collects郁 Fire (stagnant fire) of the Five Zang, and eliminates Phlegm-Fire in the upper Jiao, all being excellent. It further drives away epidemic headache and consolidates red macules caused by Shang Han (Cold Damage). For all Gan diseases, presenting with yellow complexion, red nose, dry and brittle hair, cracked lips, mouth and tongue ulcers, withered skin, and high fever, it achieves miraculous results. Although cool in nature, it does not damage the Spleen and Stomach, thus achieving divine efficacy for Gan Li (dysentery due to malnutrition) and Gan Lao (consumption due to malnutrition).
