Ku Ma Cai (Euphorbia humifusa / Spreading Spurge), also known as Yang Nai Cai (Goat's Milk Vegetable). Its taste is bitter, and its nature is greatly cold. It is a pure Yang substance, growing in sunny places, and has the effect of cooling blood. It treats hemorrhage caused by reckless movement due to blood heat. It stops all types of bleeding syndromes: hematemesis (vomiting blood), vomiting blood from the stomach, coughing up blood from the throat, expectorating blood, epistaxis (nosebleed), lower intestinal bleeding (hematochezia), and retrograde menstruation with inverted blood flow in women. It resolves phlegm, eliminates goiter (thyroid enlargement or neck masses), dissipates qi stagnation in the throat, transforms phlegm-toxin, and washes away sores-toxin.
(Attached Case) In the past, there was a person who suffered from hematemesis, expectoration of blood, coughing, blood-streaked sputum, fever with aversion to cold, soreness and pain in the limbs, spontaneous sweating (daytime sweating without exertion), and night sweats (sweating during sleep). His diet lacked flavor. The sputum he expectorated resembled agate with red and white colors, looking similar to pus. A physician prescribed this formula for him, and subsequently used it to save dozens of people; its efficacy was truly remarkable, making it a miraculous prescription.
Formula: Ku Ma Cai (crushed to extract juice, one small cup), Quan Dang Gui (Angelicae Sinensis Radix, 3 qian), Huai Shu Di (Prepared Rehmanniae Radix, 2 qian), Hang Shao (Paeoniae Radix Alba, 1 qian), Huai Sheng Di (Rehmanniae Radix, 1.5 qian), Fen Dan Pi (Moutan Cortex, 1 qian), Chen Pi (Citri Reticulatae Pericarpium, 1 qian), Chuan Bei Mu (Fritillariae Cirrhosae Bulbus, 1 qian), Hei Xuan Shen (Scrophulariae Radix, 1 qian), Bai Fu Ling (Poria, 1 qian), Tian Men Dong (Asparagi Radix, 3 qian), Zhe Mai Dong (Ophiopogonis Radix, 2 qian), Bai He (Lilii Bulbus, 1 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma, 0.5 qian). Do not use a guiding herb (Yin); decoct in water and take orally. Avoid fish, mutton, and fried or hot-natured foods.
(Additional Note) The blood in the human body is like the water in the earth. Water flows downward, so the downstream flow operates continuously, nourishing the Zang-Fu organs and penetrating the meridians. Blood belongs to Ying (Nutrient Qi), and Qi belongs to Wei (Defensive Qi). Ying and Wei circulate day and night, operating continuously. The Heart generates blood, the Spleen controls blood, the Liver stores blood, and the Kidney receives blood. When Zang-Fu organs receive blood, they become moistened; when the eyes receive blood, they can see; when the tongue receives blood, it can speak; when the hands receive blood, they can grasp; when the feet receive blood, they can walk. Blood follows the movement of Qi; if Qi moves reversely, blood also moves reversely. If diseases arise from an imbalance where Qi and Blood are excessive, labor injury causing fire to flare up will all lead to loss of blood. When Yang is excessive and Yin is deficient, fire carries blood upward, causing meridian disorder and reckless bleeding, which is termed "Ni" (Reversal). When Yang is abundant and Qi is vigorous, it ascends, and blood exits from the upper orifices, i.e., from the mouth and nose. When Yang is insufficient and Qi is deficient, it sinks, and blood exits from the lower orifices, i.e., from urination and defecation. If hematemesis occurs first, followed by sputum, or if sputum contains blood streaks, this indicates Yin deficiency with hyperactive fire; treatment should focus on nourishing Yin and descending fire. If sputum appears first, followed by blood, with purple-black blood mixed in the sputum resembling agate, this indicates accumulated heat in the Lung and Stomach; treatment should employ methods to clear the Lung, resolve phlegm, and cool the blood. Fresh red blood is new blood and should be stopped. Purple-black clots are stasis blood and should be resolved and removed. Pale yellowish blood is "white blood"; the appearance of this symptom indicates a critical condition. Epistaxis is called "Xue Nu," originating from the Liver due to extreme liver fire. Hemoptysis originates from the Lung, caused by wind invasion and heat-phlegm in the Lung; if caused by Yin deficiency and pulmonary tuberculosis, it should be treated as a deficiency syndrome. Hematemesis (spitting blood chunks) originates from the Stomach. Kidney deficiency failing to receive blood leads to vomiting blood originating from the Spleen. Hematemesis originates from the Spleen and Stomach. Saliva mixed with fresh blood originates from the Kidney. Hematuria (blood in urine) originates from the Small Intestine due to heat accumulation.
