(Lin syndrome [dysuria], hematuria, Ge Chang [intestinal obstruction], oral ulcers, Fu Jia [latent mass], Shi Yi [polyphagia with emaciation], Bi Yuan [nasal sinusitis], epistaxis, closing of eyes)
When heat from the Bao (uterus/womb) transfers to the Bladder, it results in Lin syndrome (dysuria) and hematuria; when heat from the Bladder transfers to the Small Intestine, it causes Ge Chang (intestinal obstruction with difficulty in defecation), and upward transmission leads to oral ulcers; when heat from the Small Intestine transfers to the Large Intestine, it forms Fu Jia (latent masses) and sinking accumulations; when heat from the Large Intestine transfers to the Stomach, the patient experiences polyphagia but remains emaciated, a condition also known as Shi Yi disease; when heat from the Stomach transfers to the Gallbladder, it is likewise called Shi Yi; when heat from the Gallbladder transfers to the Brain, it causes a pungent sensation and Bi Yuan (nasal sinusitis). Bi Yuan refers to the continuous flow of turbid nasal discharge. If the condition progresses to cause epistaxis and closing of the eyes, it is due to Qi reversal (Qi Jue).
The Zang organs are Yin; when Cold pathogenic factors enter, they do not transform easily, thus giving rise to diseases of transferred Cold. However, if pathogens transmit from the meridians and Fu organs to the Zang organs, the pathogenic factors have usually already transformed into Heat. The Fu organs are Yang; when Cold enters, it immediately transforms into Heat, so there are only Heat pathogens in the Fu organs, not Cold. Any Cold conditions are internal injuries, such as damage to the Stomach by raw, cold drinks or food, or deficiency patterns where Zang Cold leads to Fu Cold.
The *Nan Jing* states: Mingmen (Gate of Life) stores Essence in men and connects to the Bao (uterus/womb) in women. The Bao Mai (Bao vessels) lie between the Chong Mai (Penetrating Vessel) and Ren Mai (Conception Vessel), connecting upwards to the Heart Qi and downwards to the Bladder. Thus, the Bao is the site for conception in women and storing Essence in men. Pathogenic Heat within the Bao often arises from the brewing of desire/fire. If this Heat transfers to the Bladder, it moves from interior to exterior. If Bladder Heat stagnates in the Qi aspect, it causes urinary retention (Lin syndrome); if it injures the Blood aspect, it causes hematuria. Obstruction leads to pain, named Lin syndrome.
The Small Intestine is the official responsible for receiving and containing, transforming water and grain, and separating the clear from the turbid. The turbid descends to the Large Intestine, while the clear seeps into the Bladder. Therefore, the Bladder can also transfer Heat to the Small Intestine, causing obstruction with the Large Intestine and leading to difficult defecation. Since the turbid cannot descend, Heat steams the water vapor in the Stomach, ascending to scorch the mouth causing ulceration, and may also corrode the tongue, because the tongue is the sprout of the Heart, and the Small Intestine is the Interior-Exterior paired organ of the Heart.
The Small Intestine connects below to the Large Intestine. If Heat transfers to the Large Intestine, dregs and turbidity accumulate and fail to move, forming Fu Jia. "Fu" has the same pronunciation and meaning as "Fu". Jia refers to masses formed artificially that are fixed and difficult to remove, similar to accumulated dry feces.
The Large Intestine meridian links to the Lung, and the Lung and Stomach are connected; thus, the Large Intestine can transfer Heat to the Stomach. When the Stomach receives pathogenic Heat, appetite increases, but Heat scorches the muscles, leading to emaciation, because the Spleen and Stomach govern the muscles. This is Zhong Xiao (Middle Jiao Wasting-Thirst disease), anciently named Shi Yi.
When the Stomach transfers Heat to the Gallbladder, the pathology remains in the Middle Jiao, so the disease nature does not change significantly, though bitter taste in the mouth may occur, indicating Gallbladder Heat.
The Gallbladder meridian ascends to the head and connects to the Brain. When pathogenic Heat enters the Brain, it scorches the brain marrow, transforming it into turbid nasal discharge that flows down continuously. Because it originates from the Brain, it seems to have a pungent odor that triggers the flow of mucus, named Xin He Bi Yuan. "He" is pronounced 'he'. It is located inside the nasal bridge between the two eyes. Because it is deep in the nose and discharges foul-smelling mucus, it is named Yuan. Over time, it transmits to cause epistaxis and closing of the eyes. This occurs because turbid mucus mixed with dirty blood flows downward, causing dizziness due to Qi reversal, hence the eyes close. This condition arises from Qi Jue (Qi Reversal), indicating a severe and deep pathology.
