天御孝廉的母亲太夫人，长久以来患有胸膈部气机胀满的小毛病。最近几乎快要痊愈了。孝廉在膝下承欢侍奉，哪怕用三公的高位来交换这一天的快乐都不愿意，从今以后他的喜悦之情可想而知。
然而，考虑到太夫人福泽深厚、体质凝重，我担心病情会日益加重，最终成为晚年生活的负担。于是请求我为她制定药方，及早谋划治疗。我不由得内心受到触动，肃然起敬地说：“孝廉未曾学习过医学，却懂得‘治未病’（在疾病发生前进行预防）和‘消未萌’（在病症尚未显现时消除隐患），他对医理的领悟竟然如此深刻。由此可知，孝廉的孝心是贯彻始终、无微不至的。”
《黄帝内经》说：“阴精上奉于阳的人寿命长。”太夫人阴血充足，即使年龄超过百岁，形体也不会衰败，这是不用问就能知道的道理。但是，形体壮盛必须依靠阳气来充养，而阳气是一种逐渐衰退、消耗的物质。想要达到阴阳平衡，所依赖的药物力量就不小了。况且气还有阴阳的区别：身体上半部分由阳主司，下半部分由阴主司。如果阴气过盛并侵犯阳位（身体上部），就会导致胸膈胀闷不舒，这就是所谓的“地气上升化为云”。云层生成后，天地之间的辽阔空间顷刻间就被窒塞了。所以阴气不可过盛。阴气一旦过盛，势必要使用耗散气机的药物。气每日被耗散，身体就会日益沉重，这又不能兼用补益之术。
汉代的湖阳公主因为体质丰腴难产，御医为她配制了枳壳、厚朴等耗气的药物，命名为“瘦胎散”，这也是针对她正值壮年而言的。如果是年老气弱的时候，怎么能承受这种耗散呢？我仔细思考过这个问题。“至人”（修养极高的人）服用天气以通达神明，仅这一句话，就足以作为给太夫人用药的标准了。
大概上天通过五气供养人类，大地通过五味供养人类。用地之味来滋养阴，不如用天之气来滋养阳。药物效力持久，使天气运行而不积滞，带动地气周流运转，这就是所谓“承载华山而不觉重”，是因为有大气举托它的缘故。
方子只用茅山苍术一味药，取它雄烈之气，可以驱除阴邪而通达天气。《本草》将其列为上品，仙经称它为“山精”，确实是非常重视它。每年加工修制五到七斤。每天早晨用滚开水吞服三钱。秋季停止服用，改为二钱。另外用天门冬一钱，煎汤送服。刚开始服用的一两个月，微微觉得有些燥热；服用到一百天后，就觉得一天也不能缺少这个药了。服用一年，身体轻健；服用三年，步履如飞；黑夜中眼中放光，可以照亮幽暗隐蔽之处。所谓“服用天气而通达神明”，像这样确实不虚假。食物方面没有什么禁忌，只是能稍微远离肥腻甘甜的食物，吃白饭、香蔬、苦茶，种种清淡优越的食物尤其好。
我服用苍术后，身体健康无病，到现在已经服用了三十多斤了。
The mother of the filial scholar Tian Yu, Lady Tai, had long suffered from a minor ailment of qi distension in the chest and diaphragm. Recently, she was nearly cured without medication. The filial scholar enjoys serving her at his knees; he would not exchange one day of this joy for the position of Three Dukes (San Gong, highest officials). His subsequent joy can be imagined.
However, considering Lady Tai's blessed and heavy constitution, I feared that her condition might worsen day by day, becoming a burden in her later years. He requested me to prescribe a formula to plan ahead. I could not help but feel deeply moved within and said with reverence: "Although the filial scholar has not studied medicine, he understands 'treating disease before it arises' (Zhi Wei Bing) and 'eliminating pathology before it manifests' (Xiao Wei Meng). How profound is his understanding of medical principles! This shows that his filial piety is thorough and meticulous."
The Classic says: "Those whose yin essence is offered up [to nourish yang] live long." Lady Tai has abundant yin blood; even if she lives past a hundred, her form will not decline. This is known without asking. However, a robust form must be supplemented by qi, which is a substance that gradually declines and dissipates. To achieve balance between the two, considerable medicinal power is required.
Furthermore, qi has yin and yang distinctions: the upper half of the body is governed by yang, and the lower half by yin. If yin qi becomes excessive and invades the yang position (upper body), it causes chest and diaphragmatic distension and discomfort. This is what is meant by "earthly qi rises to become clouds." When clouds form, the vastness of heaven and earth is instantly obstructed. Therefore, yin qi should not be excessive. If yin qi is excessive, one is forced to use dispersing medicines. As qi is daily dissipated, the body becomes heavier, yet one cannot simultaneously employ tonifying methods. Princess Huyang of the Han Dynasty had difficult childbirth due to her robust physique; imperial physicians prescribed qi-dispersing herbs such as Zhi Qiao (Aurantii Fructus) and Hou Po (Magnoliae Officinalis Cortex), naming it Shou Tai San (Fetus-Thinning Powder). This was suitable only because she was in her prime. How could an elderly person with weak qi endure such dispersion? I have pondered this carefully.
"The perfected man consumes heavenly qi to connect with spirit" (Zhi Ren Fu Tian Qi Er Tong Shen Ming). This single phrase is sufficient as the standard for prescribing medicine for Lady Tai. Heaven nourishes humans with five qi, and earth nourishes humans with five flavors. Nourishing yin with earthly flavors is inferior to nourishing yang with heavenly qi. With prolonged medicinal effect, heavenly qi circulates without stagnation, carrying earthly qi in rotation. This is what is meant by "carrying Mount Hua without feeling heavy," attributed to the lifting power of great qi.
The formula uses only one herb: Maoshan Cang Zhu (Rhizoma Atractylodis Lanceae). Its potent aroma drives away yin pathogens and connects with heavenly qi. Materia Medica lists it in the Highest Class, and immortal scriptures call it "Mountain Essence," showing its high regard. Process 5-7 jin annually. Each morning, swallow 3 qian with boiling water. In autumn, stop taking it or reduce to 2 qian. Additionally, take 1 qian of Tian Dong Dong (Asparagi Radix), decocted in water, to swallow the herb. In the first month or two, one may feel slightly dry. After 100 days, one feels they cannot go a day without it. After one year of use, the body becomes light and vigorous. After three years, walking is swift as flying; at night, eyes emit light capable of illuminating darkness. Thus, "consuming heavenly qi to connect with spirit" is indeed true. There are few dietary restrictions, but avoiding rich and sweet foods is advisable. White rice, fragrant vegetables, and bitter tea are excellent. Since I took Cang Zhu, I have been healthy and free of illness, having consumed over 30 jin so far.
Mr. Hu Youchen stated: "This is a established formula. Using it to connect with heavenly qi to encompass and lift earthly qi, I feel the prescriber may not have fully discerned these deeper principles."
