The upper opening of the Stomach is named Fenmen (Cardia), through which the essence of food and drink is transported upward to the Spleen and Lungs, disseminated throughout the meridians. It is located at Zhongwan (CV12) and primarily governs the decomposition and ripening of water and grain.
The lower opening of the Stomach, which is also the upper opening of the Small Intestine, is named Youmen (Pylorus). The guiding herbs for channel transmission include Shengma (Cimicifugae Rhizoma), Gegen (Puerariae Lobatae Radix), Baizhi (Angelicae Dahuricae Radix), and Shigao (Gypsum Fibrosum). During Chen hour (07:00–09:00), qi and blood flow into the Stomach.
The Foot-Yangming Stomach Channel begins at the side of the nose. [The three Yang channels of the foot run from the head down to the feet.] It descends along the lateral aspect of the nose, enters the upper teeth, emerges, circles the lips, and crosses at Chengjiang (CV24) [located below the lower lip]. It passes behind the mandible to Jiache (ST6), travels from the hairline anterior to the ear to the forehead and skull. A branch follows the throat into Quepen (Clavicular Fossa), descends through the diaphragm, connects with the Stomach, and links to the Spleen. The main trunk descends from Quepen to Ruzhong (ST17) [along the medial edge of the breast, descending alongside the umbilicus, entering Qijie (Inguinal Artery)]. Another branch originates from Youmen, runs within the abdominal cavity downward, and eventually merges with the main trunk at Qijie. [The branch and main trunk converge at Qijie, which is located on both sides of the pubic region.] From Bituan (ST31), it reaches the patella [Bituan is an acupoint above the knee; the kneecap is called Bin], ending between the medial aspect of the tibia and the big toe. [The shin bone is called Jing; the dorsum of the foot is called Fu.] A separate branch ascends on the dorsum of the foot and meets the Foot-Taiyin Spleen Channel at the tip of the big toe. [Tip refers to the fingertip or toe tip.]
The Stomach resembles a sickle, shares a membrane with the Spleen, and attaches to the left shu point above the Stomach, corresponding to the level below the 11th thoracic vertebra. It moves upon hearing sound; this movement rubs against the Stomach and governs transportation and transformation. The guiding herbs for channel transmission include Shengma (Cimicifugae Rhizoma), Gegen (Puerariae Lobatae Radix), Cangzhu (Atractylodis Rhizoma), and Baishao (Paeoniae Radix Alba). During Si hour (09:00–11:00), qi and blood flow into the Spleen.
The Foot-Taiyin Spleen Channel originates at the big toe. [The three Yin channels of the foot run from the feet up to the abdomen.] It ascends along the medial margin of the white flesh, posterior to Hegu [the round bone medial to the proximal phalanx of the big toe], and anterior to the medial malleolus. [Hegu refers to the round bone medial to the base of the big toe. The malleolus has medial and lateral parts, known as the snail-shell bone. The round bones on either side of the wrist are also called malleoli.] It continues up the tibia to the interior of the knee, [The calf muscle is called Fei.] enters the abdomen along the anterior medial edge of the thigh, [The thigh is called Gu.] connects with the Spleen, links to the Stomach, communicates with the Diaphragm, flanks the pharynx, connects to the tongue, and spreads beneath the tongue. A collateral branch from the Stomach injects into the Heart.
The Heart is located below the lung tubes and above the diaphragm, attached to the fifth thoracic vertebra of the spine. The Heart is pointed and round in shape, resembling a lotus stamen, with orifices inside whose number varies, serving to guide primordial qi. There is no perforating orifice at the bottom, but it connects superiorly to the tongue. It has four ligaments to communicate with the four Zang organs. Outside the Heart is a layer of yellow-red fat, known as Xinbaoluo (Pericardium). Below the Heart is the diaphragm, which adheres circumferentially to the spine and ribs, shielding turbid qi so that it cannot ascend to fumigate the Heart and Lungs. The guiding herbs for channel transmission include Huanglian (Coptidis Rhizoma) and Xixin (Asari Radix et Rhizoma). During Wu hour (11:00–13:00), qi and blood flow into the Heart.
The Hand-Shaoyin Heart Channel originates in the Heart, descends through the diaphragm, and directly connects with the Small Intestine. A branch returns from the heart root, ascends to flank the pharynx, and connects to the eyeball pupil. The main trunk ascends to the Lung, emerges from the axilla, runs along the posterior medial aspect of the arm, passes through the elbow and inner arm to the back of the palm, and finally enters Shaochong (HT9) via the wrist malleolus. [Located at the medial end of the little finger.]
