Introduction: Two sets of acupoints used by Mr. He Puren to treat hemorrhoids and low-grade fever.

Chengshan (BL57), Kongzui (LU6)

Chengshan is an acupoint of the Foot Taiyang Bladder Meridian. The Bladder Meridian branch extends from the popliteal fossa to the sacrum and enters the anus. Through this branch of the Bladder Meridian that enters the anus, Chengshan can treat anal disorders. The *Jade Dragon Song* states that it is indicated for "nine types of hemorrhoids and fistulas."

The anus is connected to the large intestine, and the lung and large intestine are internally and externally related. Xi-cleft points are particularly effective in treating acute conditions and blood disorders. Therefore, Kongzui, the Xi-cleft point of the Lung Meridian, can promote bowel movement and stop bleeding.

The combined application of these two points can treat conditions such as hemorrhoidal bleeding and anal fissures.

**[Typical Case]**

Ms. Chen, female, 50 years old.

Anal fissure pain for 2 years, aggravated for 3 days. Over the past 2 years, anal fissure pain has occurred without an obvious cause, fluctuating in severity. The pain became significantly worse starting 3 days ago, with more bleeding during bowel movements. Accompanied by fatigue, poor appetite, restless sleep, normal urination, and dry stools.

The patient believes in acupuncture and requests acupuncture treatment.

Inspection: Pale tongue with thin white coating. Palpation: Deep and thready pulse.

Differentiation: Qi and blood deficiency, intestinal tract lacking nourishment. Treatment principle: Tonify qi and moisten intestines, nourish blood and stop bleeding.

Acupoints selected: Chengshan, Kongzui.

Needling method: Filiform needle technique, needles retained for 30 minutes. After the first treatment, pain decreased; after the second treatment, bleeding reduced, but hemostasis was not yet achieved.

After examination by the proctology department, diagnosed with "anal fissure," an unhealed ruptured blood vessel was found and sutured, leading to recovery.

Four Flowers

The Four Flowers refer to Danshu (BL19) and Geshu (BL17), with two points on each side, totaling four points. They are primarily indicated for the five strains and seven injuries, as well as chronic and debilitating diseases. Master He frequently uses them to treat low-grade fever.

The Danshu point is where the gallbladder qi is transported and infused. Additionally, because Shaoyang acts as a pivot, needling the Danshu point can promote the smooth flow of qi and facilitate the pivot function.

Any prolonged low-grade fever inevitably leads to the depletion of qi and blood, as well as the retention of blood stasis. The Geshu point, being the influential point of blood, can nourish blood, benefit yin, and promote blood circulation to unblock the collaterals.

The combination of these two points promotes smooth qi flow, disperses blood stasis, and enriches yin blood, thereby reducing low-grade fever.

Clinically, it can alleviate symptoms such as bone-steaming tidal fever caused by various factors, and it is particularly effective for low-grade fevers resulting from physical weakness or autonomic nervous system dysfunction.

Additionally, Dazhui (GV14), Qihai (CV6), and Pishu (BL20) are also used as acupuncture points for treating low-grade fever, often in combination with the Four Flower Points.

Dazhui (GV14) can circulate yang qi throughout the body, releasing yang and resolving heat. For those with insufficient primordial qi, pairing it with Qihai (CV6) and Pishu (BL20) can enhance the nourishing and invigorating effects on qi and blood.

【Typical Cases】

Case 1: Wang, female, 52 years old.

The patient has been experiencing subjective fever for over a year. Following surgery one year ago, she has had poor appetite, general weakness, palpitations, insomnia, occasional high blood pressure, and normal bowel and urinary functions. The tongue tip is red with a thin white coating, and the pulse is thready and rapid.

Syndrome Differentiation: Severe depletion of vital qi and deficiency of yin fluids after surgery, leading to deficiency-heat and low-grade fever. Treatment Principle: Greatly tonify vital qi and nourish yin to reduce fever.

Acupoint Selection: Dazhui (GV14), Sihua (Extra), and Qihai (CV6).

Needling Technique: A 1-cun filiform needle is inserted into the acupoints to a depth of 5–6 fen, while Qihai (CV6) is needled to a depth of 1 to 1.5 cun, all using the reinforcing method. The condition was cured after 8 acupuncture sessions.

Case 2: Patient Wang, female, 32 years old.

Low-grade fever in the afternoon for 3 months, body temperature 37.5°C. Over the past 3 months, the patient has experienced low-grade fever in the afternoon, flushed cheeks, fatigue, palpitations, insomnia, poor appetite, pale complexion, irregular menstruation, leukorrhea, with normal bowel and urinary functions. The tongue is swollen with a thin white coating, and the pulse is fine and wiry.

Pattern identification: Overthinking and fatigue impair the spleen, leading to a deficiency in the source of qi and blood production, resulting in yin deficiency fever. Treatment principle: Strengthen the spleen and stomach, alleviate fatigue-induced fever.

Acupoint selection: Dàzhuī (GV14), Sìhuā (EX-LE10), Píshū (BL20).

Needling technique: Using one-cun filiform needles, insert the needles to a depth of 5–6 fen, all with reinforcing methods.

After acupuncture, appetite slightly increased, body temperature decreased from 37.5°C to 37°C. Continuing treatment with the same acupoints, a total of 10 acupuncture sessions were administered. Low-grade fever subsided to 36.5°C, diet normalized, palpitations resolved, fatigue disappeared, recovery achieved, and the patient returned to work.
