Children possess a constitution of "pure yang" and are prone to internal heat. Depression of Heart Qi often leads to sores and carbuncles. If fetal toxins or dietary stagnation generate heat-toxins, Xijiao San (Rhinoceros Horn Powder) is the most suitable. Other cases should be treated according to standard methods. Using drastic purgatives may damage healthy Qi.
Zhu Danxi stated: Among the six Yang meridians and six Yin meridians, some have abundant Qi but scarce Blood, some have scarce Qi but abundant Blood, and some have both abundant Qi and Blood; they cannot be generalized. Among all meridians, only the Shaoyang and Jueyin meridians are prone to carbuncles and should be prevented in advance. This is because these two meridians have abundant Qi but scarce Blood; with insufficient Blood, muscle tissue struggles to regenerate, causing sores to fail to heal for a long time, inevitably leading to fatal outcomes. Some practitioners use drugs that drive out toxins and promote urination/drainage to attack the Blood of the Yin aspect, bringing disaster immediately upon doing so. When swelling and pain first appear, one must correlate pulse and symptoms; if weakness is indicated, tonification should be administered. As long as Qi and Blood remain un-depleted, auspicious recovery can be ensured. If one merely uses common heat-clearing, toxin-pulling, or Qi-regulating herbs, the disaster of exacerbating deficiency will be as obvious as looking at one's palm.
A thirty-year-old man presented with redness and swelling on the lateral aspect of his left leg. A forty-year-old man presented with redness and swelling under his ribs. Both failed to consider the scarcity of Blood in their respective meridians (Shaoyang) and rashly used Dahuang (Rhubarb Root) to purge the interior, resulting in death.
A sixty-year-old man had a nodule on the lateral aspect of his left upper arm. A young woman suffered from pain within her thigh bone. Both also failed to consider the scarcity of Blood in their respective meridians and rashly used Wuxiang Shixuan San (Five-Aromatic Ten-Point Dispersion) to induce sweating and release the exterior, resulting in death.
By differentiating according to meridians, one avoids errors involving contraindications and pathological reversals. However, the Hand Shaoyang, Hand Shaoyin, and Hand Taiyin, as well as the Foot Shaoyang, Foot Shaoyin, and Foot Taiyin, all have abundant Qi but scarce Blood. The Hand Jueyin and Hand Taiyang, as well as the Foot Jueyin and Foot Taiyang, all have abundant Blood but scarce Qi. The Hand Yangming and Foot Yangming both have abundant Blood and abundant Qi.
The above cases were not caused by changes from rich food, erysipelas, or fire-heat, but rather by consumption fatigue and Qi depression. Treatment should focus solely on tonifying the physical constitution and regulating the meridians; the sores would resolve spontaneously without needing sweating or purging. Failure to carefully distinguish the differences in pulse, symptoms, and meridian involvement before applying purgative methods constitutes a violation of disease and meridian contraindications, leading to therapeutic failure.
For internal resolution (Neixiao), one must examine the depth and size of the lesion, its location within specific meridians, and the excess or deficiency of the pulse. Lesions on the head, back, waist, neck, and buttocks belong to the Taiyang meridian and should be treated with Huanglian (Coptis Rhizome) and Qianghuo (Notopterygium Rhizome). Areas near the hypochondrium belong to the Shaoyang meridian and should be treated with Baidu San (Detoxification Powder). For patients with robust physique and excess-type pulses, Loudang Tang (Loudang Decoction) or Wuli Dahuang Tang (Five-Benefits Rhubarb Decoction) should be used to dredge and guide. For Qi deficiency, Renshen (Ginseng Root) is primary; for Blood deficiency, Danggui (Angelica Sinensis Root) and Renshen are primary, assisted by detoxifying herbs and guided by meridian-specific directing agents. The differentiation of the Six Meridians dictates supplementation or reduction based on the root and branch, cold and heat, and the abundance or scarcity of Qi and Blood in each meridian. Only the Shaoyang meridian follows the same treatment principles as conditions of Qi and Blood deficiency. (Herbs such as Gualou (Trichosanthes Fruit), Shegan (Belamcanda Rhizome), Shanjiya (Pangolin Scales), Chansu (Cicada Slough), Lianqiao (Forsythia Fruit), Dingduan (Houttuynia Herb), Niuzi (Arctium Seed), Yinhua (Honeysuckle Flower), and Mibiezi (Momordica Seed) are all herbs for internal resolution.)
