由于肾气虚寒，凝积下焦，服草神丹，灸气海穴自愈。（此证《内经》论五脏皆有，而后人以病由于肝，
先生言因肾气虚寒，总不若丹艾之妙。）
凡人至中年，脾气虚弱，又伤生冷硬物，不能营运，蕴积中焦，久之变为郁火、停疾，故令噫气，久则
成中满、腹胀之证。须服草神丹、全真丹、金液丹皆可。（吞酸为病虽微，致害非浅，苟不慎节饮食，戒谨房
帏，久久无不变成臌胀。）
凡疟病由于暑月多吃冰水冷物，伤其脾胃，久而生痰，古今议论皆差，或指暑邪，或分六经，或云邪崇，
皆谬说也。但只有脾胃之分，胃疟易治，脾疟难调。或初起一日一发，或间日一发，乃阳明证也。清脾饮、截
疟丹皆可。若二三日一发，或午后发，绵延不止者，乃脾疟也。此证若作寻常治之，误人不少。正法当服全真、
草神、四神等丹，若困重日久，肌肤渐瘦，饮食减少，此为最重，可灸左命关百壮，自愈。穷人艰于服药，只
灸命关亦可愈。凡久疟止灸命关，下火便愈，实秘法也。（脾疟原属正虚，治得其法，应手即愈，而世人竟尚
柴胡，攻多补少，不知元气既虚，又拔其本，以致耽延时日，变端百出，先生灸法，实可宗主。）
治验
一人病疟月余，发热未退，一医与白虎汤，热愈甚。余曰∶公病脾气大虚，而服寒凉，恐伤脾胃。病患
云∶不服凉药，热何时得退。余曰∶《内经》云疟之始发，其寒也，烈火不能止；其热也，冰水不能遏。当是
时，良工不能措其手，且扶元气，待其自衰。公元气大虚，服凉剂退火，吾恐热未去，而元气脱矣。因为之灸
命关，才五七壮，胁中有气下降，三十壮全愈。（久疟而用白虎，真所谓盲人说瞎话也。缪仲醇一代名医，论
多出此，窃所未解。予观《广笔记》，疑其所学，全无巴鼻，至于《本草经疏》，设立许多禁忌，令后人疑信
相半，不敢轻用，为患匪细。）
由于肾气虚寒，寒气凝积于下焦，服用草神丹，并艾灸气海穴即可自愈。（此证候在《内经》中论述五脏皆可发生，而后世医家认为病因为肝，先生认为因肾气虚寒，总不如使用丹剂和艾灸的方法精妙。）
人到中年，脾气虚弱，又损伤生冷硬物，导致脾胃不能正常运化，邪气蕴积于中焦，久而久之变为郁火、停饮之疾，所以出现嗳气，时间久了则形成中满、腹胀的证候。必须服用草神丹、全真丹、金液丹均可。（吞酸这一病症虽然看似轻微，但造成的危害并不浅显，如果不谨慎节制饮食，戒除房事，久而久之无不变成鼓胀病。）
凡是疟疾病，是由于暑月多吃冰水冷物，损伤了脾胃，日久而生痰，古今议论都有偏差，有的指为暑邪，有的分为六经，有的说是邪祟，都是谬论。只有区分脾胃的不同，胃疟容易治疗，脾疟难以调理。如果初起时一天发作一次，或隔日发作一次，这是阳明证。清脾饮、截疟丹都可以用。如果是两三天发作一次，或午后发作，绵延不止的，这是脾疟。这个证候如果当作普通疟疾治疗，误人不少。正确的方法应当服用全真、草神、四神等丹剂，如果病情沉重日久，肌肤逐渐消瘦，饮食减少，这是最重的情况，可以艾灸左命关穴一百壮，即可自愈。穷人难以服药，只艾灸命关穴也可以痊愈。凡是久疟只灸命关穴，施灸后便愈，这确实是秘法。（脾疟原本属于正气虚弱，治疗方法得当，应手即愈，而世人竟然崇尚柴胡，攻伐多而补益少，不知道元气已经虚弱，又拔除其根本，以致拖延时日，变端百出，先生的灸法，确实值得推崇。）
治验案例：
有一人患疟疾一个多月，发热未退，一位医生给予白虎汤，热势反而更重。我说：“您的病是脾气大虚，却服用寒凉药，恐怕会损伤脾胃。”病人说：“不服用凉药，热什么时候能退？”我说：“《内经》说疟疾刚开始发作时，其寒冷之象，烈火也不能止住；其发热之象，冰水也不能遏制。在这个时候，高明的医生也无从下手，暂且扶持元气，等待其自行衰退。您元气大虚，服用凉剂退火，我担心热邪未去，而元气先脱失。”于是为他艾灸命关穴，才灸五七壮（35-49壮），胁中有气下降的感觉，灸三十壮就完全痊愈了。（久疟而用白虎汤，真所谓盲人说瞎话。缪仲醇是一代名医，他的论述多出此类，我私下感到不解。我看《广笔记》，怀疑他所学毫无根据，至于《本草经疏》，设立了许多禁忌，令后人疑信参半，不敢轻用，造成的祸患不小。）
Due to deficiency-cold of Kidney Qi, coldness condenses and accumulates in the Lower Jiao (Lower Burner). Taking Caoshen Dan (Divine Grass Pill) and moxibustion on Qihai (CV6, Sea of Qi) will lead to spontaneous recovery. (This syndrome is discussed in *Neijing* as occurring in all five Zang organs, but later physicians attributed it to the Liver. Mr. Dou's assertion that it stems from Kidney Qi deficiency-cold is superior to the efficacy of pills and moxibustion.)
When people reach middle age, Spleen Qi becomes deficient. If further injured by raw, cold, or hard foods, the Spleen and Stomach cannot perform their transportation and transformation functions properly. Pathogenic factors accumulate in the Middle Jiao (Middle Burner), eventually transforming into stagnant fire and retained fluid/phlegm. This causes belching; over time, it develops into a syndrome of abdominal fullness and distension. One must take Caoshen Dan, Quanzhen Dan, or Jin Ye Dan (Golden Fluid Pill). (Although acid regurgitation appears mild, its harm is profound. Without careful dietary regulation and abstinence from sexual activity, it will inevitably progress to abdominal drum-like distension [Gu Zhang].)
Malaria arises from consuming excessive ice water and cold foods during summer months, damaging the Spleen and Stomach. Over time, phlegm generates. Ancient and modern discussions are flawed: some attribute it to Summerheat pathogen, others classify it according to the Six Channels, and some claim it is caused by evil spirits—all are erroneous theories. The differentiation lies solely in the Spleen and Stomach. Wei Malaria (Stomach Malaria) is easy to treat, while Pi Malaria (Spleen Malaria) is difficult to regulate. If it occurs once daily or every other day at onset, it is a Yangming Syndrome. Qingpi Yin (Clear the Spleen Decoction) and Jiema Dan (Antimalarial Pill) are suitable. If it occurs every two or three days, or starts in the afternoon and persists continuously, it is Pi Malaria. Treating this condition as ordinary malaria has misled many. The correct method is to take Quanzhen, Caoshen, or Sishen Pills. If the condition is severe and prolonged, with emaciation and reduced appetite, it is critical. Moxibustion on Zuomingguan (a point outside standard channels, often associated with the Spleen meridian on the left side) for 100 moxa cones will lead to recovery. For those who cannot afford medicine, moxibustion on Mingguan alone can also cure it. For chronic malaria, moxibustion on Mingguan is effective immediately after application; this is indeed a secret method. (Pi Malaria fundamentally belongs to righteous Qi deficiency. With proper treatment, recovery is swift. However, people today favor Chaihu (Bupleurum), using more purgative/attacking methods than tonifying ones. Ignoring that righteous Qi is already deficient, they uproot the foundation, causing delays and myriad complications. Mr. Dou’s moxibustion method is truly worthy of adoption.)
Case Record:
A patient suffered from malaria for over a month with persistent fever. A physician prescribed Baihu Tang (White Tiger Decoction), but the fever intensified. I said, "Your condition involves severe deficiency of Spleen Qi. Taking cold-natured herbs may damage the Spleen and Stomach." The patient replied, "If I do not take cooling medicines, when will the fever subside?" I said, "*Neijing* states that at the onset of malaria, the chills cannot be stopped by fierce fire, and the heat cannot be restrained by ice water. At such times, even skilled physicians hesitate. We should support the righteous Qi and wait for it to decline naturally. Your righteous Qi is severely deficient; taking cold decoctions to reduce fire risks losing your righteous Qi before the heat is eliminated." Therefore, I applied moxibustion to Mingguan. After only 35–49 cones, the patient felt qi descending in the hypochondrium. After 30 cones, he was completely cured. (Using Baihu Tang for chronic malaria is akin to a blind man describing colors. Miu Zhongchun, a renowned physician, made such arguments, which I find inexplicable. Reading *Guang Biji*, I suspect his learning lacked foundation. Furthermore, *Bencao Jing Shu* established numerous contraindications, causing confusion among later practitioners who dared not use these herbs lightly, leading to significant harm.)
