Individuals with robust constitutions and plump builds often have damp-phlegm (Damp-Phlegm) in their bodies. Treatment involves discussing the use of Atractylodis Rhizoma (Cangzhu, 苍术), steamed nine times, as the sovereign drug. Fangfeng Tongsheng San (Windproof Unblocking All-Purpose Powder) can treat various diseases, while one should also follow the principles of Erchen Tang (Two-Cured Decoction) as a guide.

The decline in innate constitution also stems from congenital deficiency. Their pulse is often short (Short Pulse). These individuals are prone to laziness and dislike labor, preferring warmth and disliking cold. For Taiyang disease (Taiyang Disease) and all miscellaneous diseases, methods such as sweating (Sweating Method), vomiting (Vomiting Method), and purging (Purging Method) must be used judiciously. Even for formulas that release the muscle layer (Release Muscle Layer Method), promote digestion (Promote Digestion Method), or use cold and moistening agents, one must attend to the Yuan Qi (Original Qi). Once the pathogenic trend recedes, warming and tonifying methods should be employed. However, for those with weak constitutions, external pathogens enter easily and exit easily; they can be resolved with light and dispersing agents, or even by drinking hot porridge to induce sweating. If one frequently takes tonic substances, Ren Shen Yang Rong Tang (Ginseng Nourishing Nutritive Decoction), Guipi Tang (Restore the Spleen Decoction), and Huanshao Dan (Return to Youth Pill) are excellent choices. If urine is slightly scanty, one should assess whether it is cold or heat and then use Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) or Bawei Shengqi Wan (Eight-Ingredient Kidney Qi Pill). Furthermore, wealthy families often like to take pills even when healthy, which is actually improper practice, yet there is no way to completely ignore this preference. Here, we present Zhang Xinza's Shipei Buxin Tang (Ten-Ingredient Heart-Nourishing Decoction), powder, pill, drink, and paste, chosen according to the patient's desire, which are also practical and useful formulas.

For those with weak innate constitutions, nourishment and tonification should come first. Guipi Tang (Restore the Spleen Decoction), Huanshao Dan (Return to Youth Pill), and Ren Shen Yang Rong Tang (Ginseng Nourishing Nutritive Decoction) are effective when decocted. Shipei Buxin Tang, powder, pill, and paste are exquisite, while Shengqi Wan (Kidney Qi Pill, i.e., Bawei Wan) and Dihuang Wan (Rehmannia Pill, i.e., Liuwei Wan) effectively supplement heaven (congenital essence). (Note: Commonly taken as food/supplement, I highly praise its efficacy, but using it for major illnesses would be a mistake.)

Guizhi Tang (Cinnamon Twig Decoction): Treats symptoms of Shangfeng (Wind Strike) such as spontaneous sweating, headache with neck stiffness, fever, and aversion to cold. (Note: *Shanghan Lun*, *Jinkui Yaolue*, *Qianjin Fang*, *Waitai Miyao*, and *Shengji Zonglu* all modify this formula into smaller doses for contemporary use; subsequent formulas follow this example.)
Ingredients: Guizhi (Cinnamon Twig), Baishao (White Peony Root), Shengjiang (Fresh Ginger) (each 3 qian), Zhigancao (Honey-fried Licorice Root) (2 qian), Dazao (Jujube) (4 pieces).
Usage: Decoct in water, drink hot porridge afterwards, cover with blankets to induce slight sweating. If no sweat occurs, administer again. Can be taken up to three times within a day and night. This formula uses the acrid-sweet nature of ginger, cinnamon, licorice, and jujube to tonify Yang, and the bitter-sweet nature of peony, jujube, and licorice to tonify Yin. It is a tonifying agent, not merely a sweating agent. Its brilliance lies in drinking warm porridge after administration; the grain qi overcomes the pathogen to generate sweat, thus sweating without damaging healthy Qi, eliminating the risk of complications. It can be used regardless of season, geography (north or south), age (old or young), or constitution (strong or weak).

Mahuang Tang (Ephedra Decoction): Treats symptoms of Shanghan (Cold Damage) or Shangfeng (Wind Strike) such as fever, aversion to cold, headache, body pain, neck stiffness, absence of sweat, and wheezing.
Ingredients: Mahuang (Ephedra Stem, remove root and joints, 3 qian), Guizhi (Cinnamon Twig) (2 qian), Zhigancao (Honey-fried Licorice Root) (1 qian), Xingren (Apricot Seed) (24 grains).
Usage: Use three cups of water. First, boil Mahuang until two cups remain, skim off the foam, then add other herbs and boil until eight-tenths remains. Take warm, cover with blankets to induce slight sweating. Do not drink porridge. If no sweat occurs, administer again. Can be taken up to three times within a day and night. In this formula, Mahuang and Xingren release the exterior from the surface; Guizhi and Gancao reach the exterior from the muscle layer. Porridge is not drunk because it is feared that it might linger in the stomach and enhance the sweating effect of Mahuang excessively.

Shengma Gegen Tang ( Cimicifuga and Pueraria Decoction, attributed to Qian Zhongyang): Treats Yangming Shanghan (Yangming Cold Damage) or Shangfeng (Wind Strike), presenting with headache, body pain, fever, aversion to cold, absence of sweat, thirst, eye pain, nasal dryness, inability to sleep, as well as Yangming macules (skin eruptions) that wish to emerge but do not, irregular weather changes, and epidemic diseases prevalent among people.
Ingredients: Shengma (Cimicifuga Rhizome) (3 qian), Gegen (Pueraria Root), Baishao (White Peony Root) (each 2 qian), Zhigancao (Honey-fried Licorice Root) (1 qian). Add fresh ginger and decoct.
I believe Gegen (Pueraria Root) can be used in doses of 3-4 qian, while Shengma (Cimicifuga Rhizome) should only be used in small amounts around 1 qian. Adding Chuanxiong (Ligusticum Rhizome), Baizhi (Angelica Dahurica Root), Zisu (Perilla Leaf), Huangqin (Scutellaria Root), Shigao (Gypsum Fibrosum), etc., is also acceptable.
This formula is not the primary formula for Yangming syndrome in *Shanghan Lun*. Merely discussing the exterior syndrome, Yangming considers the muscle layer as the exterior, which differs from Taiyang. Therefore, Gegen (Pueraria Root) is taken as the sovereign drug to clear heat from the muscles. Porridge is not drunk because it is feared that tonifying the Stomach will increase heat.
Commentary: Regarding Yangming syndrome, *Neijing* (*Inner Canon*) sets "body heat, eye pain, nasal dryness, and inability to sleep" as the outline, while Zhang Zhongjing sets "Stomach House Excess" (Wei Jia Shi) as the outline. The theories of former and latter sages differ. Some follow Song dynasty physicians using Shengma Gegen Tang, adhering to the transmission of Jing-Qi (Meridian Qi) in *Neijing*. However, Gegen (Pueraria Root) is not the orthodox herb for Yangming; it is used to diffuse muscle collaterals and remove great heat, taking advantage of Yangming's governance over muscles and its tendency to manifest steaming heat. At the beginning of *Shanghan Lun*, there are methods using Guizhi Tang (Cinnamon Twig Decoction) and Mahuang Tang (Ephedra Decoction), but no method using Gegen Tang. The condition often transmits to Baihu Tang (White Tiger Decoction) syndrome or Chengqi Tang (Assist the Qi Decoction) syndrome. The treatment methods of ancient and modern times are consistent.

Xiao Chaihu Tang (Minor Bupleurum Decoction) (Formula seen below): Treats Shaoyang disease, presenting with hypochondriac pain, vertigo, deafness, bitter taste in the mouth, alternating chills and fever, vomiting, etc. In *Shanghan Lun*, this formula is used because the pathogenic factor of Taiyang disease wishes to exit through Shaoyang, and this formula assists the pivot mechanism. However, true Shaoyang syndrome does not exceed this formula, as Shaoyang governs the pivot, and Chaihu (Bupleurum Root) is the divine substance for turning the pivot. Do not mistakenly regard it as a sweating agent.
Commentary: The head is the convergence point of all Yang meridians. Yang syndromes of Shanghan (Cold Damage) and Shangfeng (Wind Strike) must necessarily involve headache. *Jing* (*Neijing*) states: The Taiyang meridian, the straight branch, enters from the vertex to connect with the brain, emerges again at the lower occiput, follows the shoulder blades along the paraspinal region, and reaches the waist. Therefore, Taiyang headache involves brain pain connecting to the neck and spine. The Yangming meridian originates at the nose, connects with the eyes, and intersects at the forehead. Therefore, Yangming headache involves frontal pain connecting to the face and eyes. The Shaoyang meridian originates at the outer canthus of the eye, ascends to the temporal angle, descends behind the ear. Its branch enters the ear from behind the ear, exits anterior to the ear. Therefore, Shaoyang headache involves pain around the ears, connecting upwards to the temporal angle.
