The presentation resembles Taiyang disease (disease of the Taiyang channel), but the pulse is not wiry and tight; instead, it is weak. A weak pulse indicates thirst. If treated with fire therapy, delirium (Zhenyu) will inevitably occur. In cases of weak pulse with fever and floating pulse, the pathogen should be resolved through sweating.
"Resembling Taiyang disease" refers to headache and body heat. The absence of a wiry and tight pulse indicates the lack of typical exterior syndrome pulses for Taiyang disease. The classics state: "Weakness with fever," indicating that a weak pulse signifies interior heat; thus, those with a weak pulse must experience thirst. If subjected to fire qi, the internal and external heats combine and contend in the Stomach. Dryness and irritability in the Stomach will inevitably lead to delirium. When a patient presents with a weak pulse and fever, if the pulse becomes floating, it indicates the pathogen has returned to the exterior. Recovery will occur through perspiration.
Wang Sanyang stated: This condition does not strictly require treatment; waiting for spontaneous sweating will lead to recovery. If the pulse fails to become floating, mild clearing of heat using wine-fried Scutellaria Root (Huangqin) and Phellodendron Bark (Huanglian) is acceptable.
In Taiyang disease, if moxibustion or fire fumigation is applied and sweat is not produced, the patient will inevitably become restless. If the disease cycle passes without resolution, hematochezia (blood in stool) will occur, termed "Fire Pathogen."
This represents blood forced downward by the Fire Pathogen. In Fire Yang disease, if fire fumigation is used without producing sweat, the heat has no outlet. In patients with Yin deficiency subjected to fire, restlessness will inevitably ensue. After six days, when the transmission of channels is complete, and on the seventh day returning to the Taiyang channel, the heat should resolve. If it does not, the heat forces blood downward, resulting in bloody stools.
If the pulse is floating and heat is severe, applying moxibustion is contraindicated. This is an Excess pattern treated as Deficiency. Due to the disturbance caused by fire, dryness of the throat and hemoptysis (spitting blood) will inevitably occur.
This represents blood forced upward by the Fire Pathogen. A floating pulse with severe heat indicates Exterior Excess. If the physician mistakenly treats the floating pulse as Deficiency and applies moxibustion, the fire qi moves the blood, forcing it upward, causing dryness of the throat and hemoptysis.
For a pulse that is slightly rapid (Wei Shu), moxibustion must be strictly avoided. Fire becomes a pathogenic factor, leading to vexation and rebellious qi. It pursues Deficiency while simultaneously aggravating Excess, causing blood to scatter within the vessels. Although the fire qi may be slight, its internal attacking power is strong, potentially scorching bones and damaging sinews, making blood restoration difficult.
A slightly rapid pulse indicates Heat. Moxibustion dispels Cold but cannot dissipate Heat; therefore, it is strictly contraindicated. If moxibustion is incorrectly applied, the heat intensifies due to fire, leading to vexation and rebellious qi. Moxibustion is intended to tonify Deficiency, but here it exacerbates Heat into Excess. Heat injures blood, and combined with fire qi, causes blood to scatter within the vessels. Qi warms, and Blood moistens. With the dissipation of Qi and Blood, they can no longer nourish sinews and bones, resulting in scorched bones and damaged sinews, with scattered blood being difficult to restore.
When the pulse is floating, the exterior should be resolved through sweating. If moxibustion is used, the pathogen has no exit. Aggravated by fire, the condition below the waist will become heavy and numb, termed "Fire Reversal" (Huo Ni).
A floating pulse indicates the exterior; it should be resolved through sweating. If the physician uses moxibustion to induce sweat but fails to do so, the pathogen has no outlet. Assisted by fire qi, the heat intensifies. The upper half of the body corresponds to Heaven's Yang; the lower half corresponds to Earth's Yin. Fire nature flares upward. Consequently, in the lower half, Yin qi dominates exclusively. Thus, from the waist down, heaviness and numbness will inevitably occur.
Spontaneous resolution occurs first with vexation, followed by sweating and recovery. How do we know this? Because the pulse is floating, we know recovery comes through sweating.
Vexation and heat indicate the pathogen returning to the exterior. Sweating resolves the condition because the floating pulse signals the pathogen's return to the exterior.
If pricking needles induces sweating, and the needle site is exposed to cold, forming a nodule that turns red, Ben Tun (Rolling Pig, a condition where Qi rushes from the lower abdomen to the heart) will inevitably develop. If Qi rushes from the lower abdomen to the heart, apply one moxa cone directly on each nodule to disperse the cold, and administer Guizhi Jia Gui Tang (Cinnamon Twig Decoction with Added Cinnamon Twig), increasing the amount of Cinnamon Twig by 3 liang.
Pricking needles to induce sweating damages Yin Blood and startles Heart Qi. Cold gathers at the needle site, forming nodules. Heart Qi becomes deficient due to fright. Kidney Qi moves in conjunction with the cold pathogen, triggering Ben Tun. The *Jin Gui Yao Lue* states: "Ben Tun arises from fright." Kidney Qi attempts to ascend to the Heart, causing Qi to rush from the lower abdomen to the heart. First, moxa is applied to the nodules to disperse cold, and Guizhi Jia Gui Tang is given to drain the Qi of Ben Tun.
