【气味】
味苦、性平，无毒。是足阳明胃经和足厥阴肝经的药物。
【主治】
厥阴肝经主司筋脉，与风相关；阳明胃经主司肌肉，与湿相关。萆薢的功效长于祛除风湿，所以能治疗肢体软弱无力、痹证、遗精白浊、恶疮等各种疾病。因此有萆薢分清饮，用它来治疗真元不足、下焦虚寒、小便频数、尿液浑浊如膏的病症。另外，有人饮酒过度，或者不饮酒却过食辛辣温热及荤腥油腻之物，又或因房事过度，导致小便频数且疼痛。这与淋证涩痛不同。适宜使用萆薢来驱逐积聚的毒素，去除浊气而澄清尿液。
【气味】
味甘、淡，性平，无毒。
【主治】
健运脾胃。祛除风湿。通利关节。治疗拘挛、骨痛、恶疮、肿胀。解除汞粉、银朱的毒性。近代有些风流之人，多患有杨梅毒疮（梅毒）。他们追求速效，常常使用轻粉、银朱等药物，虽然暂时治愈但容易复发。其毒素结聚在阳明、厥阴二经并涉及其他经络，导致邪气所在之处首先发作。如果兼涉少阳、太阴经，则发于咽喉；如果兼涉太阳、少阴经，则发于头耳。总归是因为相火寄居于厥阴经，肌肉归属于阳明经。水银、轻粉的燥烈之性，虽然能劫夺脾胃中的痰湿，使诸火上升，使得毒疮瞬间痊愈，却不知道毒气窜入经络筋骨之间，无法排出。痰涎虽出，但血液随即耗损，筋脉失去滋养，营卫失调，最终变为痈漏（久治不愈的疮疡）。只有土茯苓，气平味甘而淡，是阳明经的本药，能健运脾胃、祛除风湿。脾胃强健则营卫调和，风湿去除则筋骨便利。这也是古人未曾言说的秘密。

[Flavor and Properties]
Sweet, neutral, non-toxic. Capable of ascending and descending. It is Yin within Yang.
[Indications]
Wind pathogen invading the four extremities. Tearing and ulceration of both eyes. Lower back pain caused by dampness pouring downward in men. Black spots appearing on the face in women. Treating spontaneous sweating due to wind-warmth. Heaviness of the body and difficulty in speech. Chills and fever, epistaxis, malaria, and all conditions of deficiency arising from consumptive disease. It can be used as a substitute for Ginseng Radix et Rhizoma (Renshen). Neither hot nor drying, it has remarkable efficacy.
[Flavor and Properties]
Bitter, neutral, non-toxic. It is Yang within Yin.
[Indications]
Old fixed masses and abdominal lumps. Postpartum lochia retention. Breaking up stagnant Qi. Resolving blood stasis from traumatic injuries. Contraindicated for those with deficient True Qi.
[Flavor and Properties]
Bitter, neutral, non-toxic. A herb entering the Foot-Yangming Stomach Channel and Foot-Jueyin Liver Channel.
[Indications]
The Jueyin channel governs tendons and is associated with Wind; the Yangming channel governs flesh and is associated with Dampness. The efficacy of Dioscoreae Hypoglaucae Rhizoma (Bifan) excels in dispelling Wind-Dampness, thus it can treat conditions such as flaccidity, bi-syndrome, seminal emission with turbid urine, and foul sores. Therefore, Bifen Qingfen Yin (Dioscorea Hypoglauca Decoction for Clarifying Turbidity) uses this herb to treat conditions of insufficient True Yuan, cold-deficiency in the Lower Jiao, frequent urination, and turbid urine resembling paste. Additionally, excessive alcohol consumption, or overindulgence in spicy, warm, meaty, and greasy foods without drinking alcohol, or excessive sexual activity, can lead to frequent and painful urination. This differs from strangury characterized by涩 (astringency) and pain. It is appropriate to use Dioscoreae Hypoglaucae Rhizoma (Bifan) to expel accumulated toxins, remove turbidity, and clarify the urine.
[Flavor and Properties]
Sweet, bland, neutral, non-toxic.
[Indications]
Strengthens the Spleen and Stomach. Dispels Wind-Dampness. Benefits the joints. Treats spasms, bone pain, foul sores, and swelling. Detoxifies mercury powder and cinnabar. In recent times, many promiscuous individuals suffer from ymei du chuang (chancre/venereal sore, i.e., syphilis). Seeking quick results, they often use herbs like Calomelas (Qingfen) and Cinnabar (Yinzhu). Although these may provide temporary relief, the condition frequently recurs. The toxin accumulates in the Yangming and Jueyin channels and involves other meridians, causing the evil to manifest first where it resides. If involving Shaoyang and Taiyin, it manifests in the throat; if involving Taiyang and Shaoyin, it manifests in the head and ears. Generally, because Ministerial Fire resides in the Jueyin channel and muscles belong to the Yangming channel, the drying and fierce nature of mercury and calomelas can forcibly extract phlegm from the Spleen and Stomach, causing various fires to ascend, making the venereal sores heal instantly. However, one does not realize that the toxic qi invades the collaterals, sinews, and bones, unable to exit. Although phlegm saliva is expelled, blood essence is rapidly consumed, sinews lose nourishment, Ying and Wei Qi become disordered, transforming into chronic ulcers (onglou). Only Smilax Glabrae Rhizoma (Tufuling) has neutral Qi, sweet and bland flavor. It is the primary herb of the Yangming channel, capable of strengthening the Spleen and Stomach and dispelling Wind-Dampness. When the Spleen and Stomach are strong, Ying and Wei Qi harmonize; when Wind-Dampness is removed, sinews and bones become flexible. This is also a secret unknown to the ancients.
