白附子因感受阳气而生，所以味道辛，气味大温，有小毒。其性质燥烈且升散，是风药中的阳草。李东垣认为它纯阳，能引导药势上行，能够去除面部的各种疾病，消除瘢痕瑕疵，擦拭汗斑，豁除风痰，驱逐寒邪，燥湿散结，是治疗中风痰厥、小儿急惊的重要药物。但是它的性质温燥，凡是阴虚类中风的病症，以及小儿脾虚引起的慢惊风，都应当严格禁忌。
白附子主治诸风冷气、中风失音、血痹冷痛，能消痰祛湿，并且引导药势上行，祛除面部各种疾病。如果是大人阴虚类中风，或小儿脾虚慢惊，千万不要误用。
主治（痘疹合参）：治疗痘疮风热不退，以及四肢头面部位痘疹不起发，用它来疏散风邪、清利热毒。
萆薢得火土之气，兼禀受天的阳气，所以味道苦甘，性平，无毒。归足阳明胃经、足少阴肾经、足厥阴肝经。它是祛风除湿、补益下焦的重要药物。
萆薢忌与牛肉同食。白色者为佳。主治风寒湿痹、腰背冷痛、筋骨牵引疼痛，能补水脏、益精、缩小便、明目、逐关节之邪，消散久结的老血，清扫肌肤，延年益寿，治疗恶疮、恚怒伤中、老人五缓等症。它的功效专长于祛湿而弱于清热，既能去除膀胱积水，又能止住遗尿和尿频。凡是杨梅痔、恶疮，病久导致火衰气耗、湿郁的情况，可用萆薢三两，皂角刺、牵牛子各一钱，加水六碗，煎至剩一半，分三次温服，不需多剂即可痊愈。初服未见效的，是因为体内火热尚盛。
主治（痘疹合参）：治疗痘疮水泡过多，不能干燥结痂的，用它来渗泄收摄湿气。
按语：萆薢的主要用途，都是祛风湿、补下元。凡是小便频数、尿道内疼痛，必定是大肠热闭，水液只流向小肠，大肠更加燥竭，因为强忍房事，有瘀腐壅塞在下焦所以疼痛。这与淋证不同，宜用盐炒萆薢一两，煎服，并用葱汤清洗肛门，即可痊愈。肾受到土邪侵犯则水衰，肝挟带相火来复，母仇而凌犯脾土，得到萆薢以渗湿，则脾土安守其位，水液就不受侮辱了。如果是阴虚火旺，以及无湿而肾虚腰痛者，不要服用。
Bai Fu Zi (Rhizoma Typhonii) is born from the sensation of Yang Qi, thus its flavor is pungent, its qi is greatly warm, and it has slight toxicity. Its nature is drying and ascending; it is a Yang herb among wind-dispelling drugs. Li Dongyuan stated that it is purely Yang, guides the medicinal force upward, can remove various diseases on the face, eliminates scars and blemishes, wipes away sweat spots, expels wind-phlegm, drives out cold pathogens, dries dampness and dissipates nodules. It is an essential medicine for treating stroke with phlegm and syncope, and acute convulsions in children. However, its nature is warm and drying. For conditions resembling stroke due to Yin deficiency, and slow convulsions in children due to Spleen deficiency, it must be strictly contraindicated.
Bai Fu Zi (Rhizoma Typhonii) treats various wind-cold qi stagnation, aphonia due to stroke, blood bi with cold pain. It reduces phlegm and dispels dampness, and guides the medicinal force upward to remove various diseases on the face. If adults have conditions resembling stroke due to Yin deficiency, or children have slow convulsions due to Spleen deficiency, do not use it by mistake.
Main Indications (Integration of Smallpox and Rashes): Treats smallpox/rash where wind-heat does not subside, and where lesions on limbs, head, and face fail to erupt. Use it to disperse wind, clear heat, and resolve toxicity.
Bi Xie (Dioscoreae Hypoglaucae Rhizoma) obtains the Qi of Fire and Earth, and additionally inherits the Yang Qi of Heaven. Thus, its flavor is bitter and sweet, its nature is neutral, and it is non-toxic. It enters the Foot-Yangming Stomach Meridian, Foot-Shaoyin Kidney Meridian, and Foot-Jueyin Liver Meridian. It is an essential medicine for dispelling wind, removing dampness, and tonifying the lower jiao.
Bi Xie (Dioscoreae Hypoglaucae Rhizoma) is incompatible with beef. The white variety is superior. It treats wind-cold-damp bi, cold pain in the waist and back, pulling pain in bones and sinews. It nourishes the Water organ, benefits essence, reduces urination, brightens the eyes, expels joint pathologies, resolves old blood stasis, clears the skin, prolongs life, treats malignant sores, anger damaging the middle, and the "Five Laxities" in the elderly. Its merit lies primarily in resolving dampness, while it is inferior in clearing heat. It can drain water accumulation in the Bladder and stop enuresis and frequent urination. For cases of chancroid/malignant sores where the disease has persisted, leading to decline of fire, consumption of Qi, and dampness stagnation, use Bi Xie (Dioscoreae Hypoglaucae Rhizoma) 3 liang, along with Gleditsiae Spina (Gleditsiae Sinensis Spina) and Phelodendri Cortex (Phellodendri Amurensis Cortex) [Note: Text says 'Jiao Ci Qian Niu' which usually refers to Gleditsia and Morning Glory seed, but context implies specific herbs. 'Qian Niu' is Pharbitidis Semen. 'Jiao Ci' is Gleditsiae Spina.] each 1 qian, add 6 bowls of water, decoct until half remains, take warm in three doses. Recovery often occurs within a few doses. If there is no effect after the first dose, it is because the internal fire is still vigorous.
Main Indications (Integration of Smallpox and Rashes): Treats smallpox/rash where vesicles are too abundant and cannot dry and crust over. Use it to渗泄 (percolate and absorb) dampness.
Commentary: The main uses of Bi Xie (Dioscoreae Hypoglaucae Rhizoma) are all to dispel wind-dampness and tonify the lower Yuan. Whenever there is frequent urination and pain inside the urethra, it must be due to heat closure in the Large Intestine. Fluids only flow to the Small Intestine, causing the Large Intestine to become increasingly dry and exhausted. This is caused by forcibly restraining sexual intercourse, leading to stasis and putrefaction obstructing the Lower Jiao, hence the pain. This differs from Lin Syndrome (Strangury). It is appropriate to use Salt-fried Bi Xie (Dioscoreae Hypoglaucae Rhizoma) 1 liang, decoct and drink. Wash the anus with Scallion Decoction, and it will heal. When the Kidney is affected by Earth-pathogens, Water declines. The Liver, carrying Ministerial Fire, retaliates against the Mother (Water) and insults Earth. With Bi Xie (Dioscoreae Hypoglaucae Rhizoma) to percolate dampness, Earth remains stable in its position, and Water is no longer insulted. Do not use if there is Yin deficiency with blazing fire, or Kidney deficiency without dampness presenting as lower back pain.
