百合病如果没有经过催吐、泻下或发汗等误治，病情表现与初起时相同，用百合地黄汤主治。
百合（七枚） 生地黄汁（一升）
以上两味药，先按前述方法煎煮百合，取药液一升，滤去药渣，加入生地黄汁，再煎取一升五合的药液，分两次温服。服药后若见效，不要再服用。
歌诀云：
未经汗、吐、下法损伤，
症状仅如初起，病在太阳经。（指病程迁延日久，始终在太阳经未发生传变者。）
生地汁一升，
百合七枚。
元犀按语：
百合病日久，未经过吐、下、发汗等治疗，病情表现仍如初起，这是郁滞日久化热，耗伤了气血。使用百合地黄汤，是因为服药后热邪随大便下行排出。所以形容药液颜色像漆一样黑。
百合病一个月未愈，出现口渴症状的，用百合洗方主治。
百合（一升）
用水一斗，浸泡百合一整夜，用此水洗澡，吃完煮饼，不要用咸豆豉调味。
歌诀云：
满月未愈口渴形成，
邪热流连于肺，肺气不清。
百合一升用水一斗，
洗澡吃饼不调羹。（不要用咸豆豉）
（合参）
皮毛是肺的外合，清洗体表，也是为了疏通体内。另外吃煮饼，是借助麦子和谷物的气机来输布津液。
不用咸豆豉，是担心咸味耗伤阴液从而加重口渴。
百合病口渴症状未缓解的，用栝楼牡蛎散主治。
栝楼根 牡蛎（煅制，等量）
以上两味药研成细末，用温水送服一方寸匕，每日三次。
歌诀云：
洗浴后仍然口渴属于浮阳上越，
牡蛎和栝楼根并等量。
研成粉末用水调服一方寸匕，
兼具苦寒和咸寒之性，
疗效超越……
元犀按语：
洗浴后口渴仍未缓解，说明体内的阴气尚未恢复。阴气未恢复，是由于阳气亢盛所致，所以用牡蛎来潜降阳气。
百合病出现发热症状的，用百合滑石散主治。
百合（一两，炙） 滑石（三两）
以上两味药研成散剂，用温水送服一方寸匕，每日三次。当出现轻微腹泻时停止服药，热邪即可消除。
歌诀云：
此前既无寒象也无热象。（第一章说像冷不像冷，像热不像热。）
变成发热令人担忧，
清利疏泄滑石宜用三两。
元犀按语：
百合病原本没有偏热的证候，出现发热症状，是内热充满，浸淫于肌肤，不同于一般的实热证。主治用百合滑石散。

Baihe Bing (Lily Disease) that has not undergone emesis, purgation, or diaphoresis, and whose clinical manifestations remain unchanged from the initial stage, is primarily treated with Baihe Dihuang Tang (Lily and Rehmannia Decoction).
Baihe Rhizoma (Lilii Bulbus) (7 pieces). Shengdihuang Juice (Rehmanniae Radix Fresh Juice) (1 sheng).
First, decoct the Lilii Bulbus according to the previous method, obtaining 1 sheng of liquid. Strain out the dregs, add the Rehmanniae Radix Fresh Juice, and decoct again to obtain 1.5 sheng. Take half warm each time. If the disease is cured, do not take more.
The song states:
Not injured by diaphoresis, purgation, or emesis;
The form remains as at the beginning, staying in the Taiyang channel. (Referring to cases where the disease lingers for a long time but remains unchanged in the Taiyang channel.)
One sheng of Dihuang juice,
Seven Lily bulbs.
Commentary by Yuanxi:
When Baihe Bing persists for a long time without undergoing emesis, purgation, or diaphoresis, and the clinical presentation remains unchanged, it indicates that stagnation has generated heat over time, consuming Qi and Blood. The use of Baihe Dihuang Tang is because the pathogenic heat is discharged downward through the stool after medication. Hence, it is described as being black like lacquer.
If Baihe Bing persists for one month without resolution and transforms into thirst, this formula is primarily indicated.
Baihe Rhizoma (Lilii Bulbus) (1 sheng).
Soak in 1 dou of water overnight. After bathing with this water, eat boiled wheat noodles. Do not use salty fermented soybeans (Chidou).
The song states:
After a month unresolved, thirst arises;
Pathogenic heat lingers in the Lung, causing clear function to fail.
One sheng of Lilii Bulbus with one dou of water;
Bathe and eat noodles without soup. (Do not use salty Chidou.)
(Combined Reference):
The skin and hair are the exterior correspondence of the Lung; washing the exterior also helps to unblock the interior. Eating boiled wheat noodles utilizes the Qi of wheat and grains to distribute body fluids.
Avoiding salty Chidou prevents the salty flavor from consuming Yin fluids and exacerbating thirst.
If Baihe Bing presents with persistent thirst despite treatment, this powder is primarily indicated.
Gualougen (Trichosanthis Radix) and Muli (Ostreae Concha), calcined, in equal parts.
Grind into fine powder. Take one fangcun bi (one square-inch spoonful) mixed with water, three times daily.
The song states:
Persistent thirst after bathing belongs to floating Yang;
Muli and Gualougen are used in equal measure.
Grind into powder and mix with water for one fangcun bi;
Combining bitter-cold and salty-cold properties,
The efficacy surpasses...
Commentary by Yuanxi:
Thirst persisting after bathing indicates that the Yin Qi within has not yet recovered. The failure of Yin Qi to recover is due to the hyperactivity of Yang Qi; therefore, Ostreae Concha is used to subdue the Yang.
If Baihe Bing transforms into fever, this powder is primarily indicated.
Baihe Rhizoma (Lilii Bulbus), roasted (1 liang); Huashi (Talcum) (3 liang).
Grind into a powder. Take one fangcun bi mixed with water, three times daily. Stop taking the medicine when slight diarrhea occurs; the heat will then be eliminated.
The song states:
Previously, there was neither cold nor heat. (Chapter One describes it as feeling like cold but not being cold, feeling like heat but not being heat.)
Transforming into fever is alarming;
Clearing and dispersing with Talcum, three liang is appropriate.
Commentary by Yuanxi:
Baihe Bing originally lacks signs of excess heat. When fever develops, it indicates an abundance of internal heat permeating the skin and muscles, which differs from typical heat syndromes. The primary treatment uses Baihe Huashi San (Lily and Talc Powder).
Take the powder...
