呕属阳明。有物有声。气血俱病也。仲景云。呕多虽有阳明证。不可下。

Those who speak "Kuang Yan" (Manic Speech) open their eyes wide and converse with others, discussing matters they have never seen; this is called Kuang Yan.
Those who speak "Zhen Yu" (Delirious Speech) close their eyes and talk to themselves, speaking of things commonly seen and done in daily life; this is called Zhen Yu.
Those who exhibit "Zheng Sheng" (Feeble Voice) have a trembling and weak voice that does not connect continuously, with words issuing from the throat; this is called Zheng Sheng.
The answer states: The Stomach (Wei) acts as the general manager. Internally, there are distinctions among the Taiyang (Greater Yang), Yangming (Yang Brightness), and Shaoyang (Lesser Yang) meridians. Due to differences in the quantity of Qi and Blood, there are variations in vocalization and the presence or absence of expelled matter.
If vomiting belongs to the Taiyang meridian, it involves expelling matter without sound, indicating a disease of the Blood level. There are distinctions such as vomiting immediately after eating, vomiting shortly after eating, and vomiting after food has remained for a long time.
Vomiting (Ou) belongs to the Yangming meridian, involving both matter and sound, indicating a disease affecting both Qi and Blood. Zhang Zhongjing stated: "If there is much vomiting, even if there are Yangming syndrome manifestations, purgation must not be used."
Hiccups (Yue) belong to the Shaoyang meridian, involving sound without matter, indicating a disease of the Qi level. By inferring from this, bowel movements also correspond to specific meridians. By observing whether there is matter without sound, matter with sound, or sound without matter, one can determine which meridian is affected. Regarding Spleen diseases, the expulsion of residual gas can be distinguished by the five odors to identify which Zang organ's pathogenic factor has entered the Middle Jiao causing illness.
Diseases may arise from premature purgation, from failure to use purgation when indicated, or from Stomach Heat or Stomach Rot. Although the causes differ, generally they all involve the Earth element (Stomach/Spleen) assisting the Hand-Shaoyang Heart Fire to enter the Hand-Taiyin Lung meridian. Consequently, red spots like millet grains appear between the skin and hair follicles. (Baihu Tang / White Tiger Decoction), (Xiexin Tang / Drain the Epigastrium Decoction), (Tiaowei Chengqi Tang / Regulate the Stomach and Direct Downward Decoction) should be used according to indications. Differentiation should also be made via the Lung pulse.
The answer states there are nine types. Taiyang, Yangming, Shaoyang, Taiyin, Shaoyin, and Jueyin constitute six. Additionally, there are Taiyang-Yangming, Shaoyang-Yangming, and Zhengyang-Yangming, constituting three more. Thus, they total nine. Yangming disease refers to the transmission of pathogens from both Taiyang and Shaoyang meridians into the Stomach, hence termed Zhengyang-Yangming (True Yangming). For the first three meridians, if Yangming disease occurs spontaneously without entering the interior, it is termed "in the meridian" and does not qualify as Zhengyang-Yangming.
Taiyang-Yangming is treated with Dachengqi Tang (Major Order the Qi Decoction). Shaoyang-Yangming is treated with Xiao Chengqi Tang (Minor Order the Qi Decoction). Zhengyang-Yangming is treated with Tiaowei Chengqi Tang (Regulate the Stomach and Direct Downward Decoction).
Regarding sweating syndromes: Since Shaoyang resides in the middle, Taiyang syndromes are considered exterior and require diaphoresis; Yangming syndromes are considered interior and require purgation. Because Shaoyang is in the middle, treatment neither employs diaphoresis nor purgation, but rather harmonization using Xiaochaihu Tang (Minor Bupleurum Decoction) targeting the Shaoyang meridian.
Regarding purgation syndromes: Yangming resides in the middle. Taiyang meridian has abundant Blood and scarce Qi; Yangming meridian has abundant Qi and Blood; Shaoyang meridian has abundant Qi and scarce Blood. If one purges directly from Taiyang, one offends Shaoyang; if one purges directly from Shaoyang, one offends Taiyang. Therefore, treatment focuses solely on Yangming. This combination of the three Yang meridians is called Zhengyang-Yangming. It follows the Middle Qi rather than the Root or Branch. Because the Yangming meridian lies between Taiyang and Shaoyang, and possesses abundant Qi and Blood, its central position is prioritized. Thus, treatment follows Yangming rather than Taiyang or Shaoyang. Spontaneous Yangming disease is primarily treated with Tiaowei Chengqi Tang. Concurrent illness of the three Yang meridians is primarily treated with Baihu Tang (White Tiger Decoction). This exemplifies following the Middle Qi.
