🌿 Folk Prescriptions

Dysmenorrhea is a common gynecological disorder, traditionally treated according to patterns such as qi stagnation and blood stasis, cold congealing in the uterus, or liver-kidney deficiency. Classical formulas like Yao Hong Si Wu Tang, Wen Jing Tang, and Tiao Gan Tang have proven effective. However, for severe cases such as membrane-type dysmenorrhea or endometriosis with intense pain, specific formulas are required. This article proposes naming this condition "Dysmenorrhea due to Yin Deficiency with Damp-Heat and Blood Stasis."
This condition commonly affects young women in low-lying, water-rich regions, many of whom have histories of menstrual hygiene lapses involving swimming, fishing, working in water, or being exposed to rain outdoors. During onset, patients experience tight, hard, burning abdominal pain; heat application worsens pain. Some may find relief with warmth, indicating cold-congealed type. There are abundant black, viscous clots differing from qi-blood stagnation (more distension, less pain, fewer bright red clots) and from membrane-type dysmenorrhea (with sheet-like discharge). This condition results from cold-damp pathogens invading the uterus during menstruation, transforming into heat toxins over time, causing blood stasis and damage to the uterus—leading to complex, mixed deficiency-excess patterns with severe pain.
1. Brief Analysis of Cause and Mechanism
Cold-damp turbidity is inherently yin-cold, sticky, obstructing qi flow, and prone to chronic, entangled illness. Initially injuring yang, prolonged exposure transforms into heat-toxins damaging yin. During menstruation, uterine lining sheds, leaving open wounds. Cold-damp toxins directly invade these wounds, making the uterus vulnerable. Sudden exposure of warm menstrual fluid to cold water causes abrupt stagnation of uterine vessels—this is one cause of dysmenorrhea. Many women develop dysmenorrhea after consuming cold drinks or abdominal chilling during menstruation, confirming that cold-induced vessel stagnation can trigger pain. From a modern medical perspective: rivers, lakes, and marsh waters are not only cold and unclean but often harbor various pathogens. When the uterine wound remains unclosed during menstruation and contacts contaminated water, bacterial infection frequently occurs, leading to pelvic inflammatory disease or endometritis—causing abdominal pain. Modern medicine attributes such pain to menstrual exposure to water or unhygienic bathing and sexual activity. Inflammation produces pathological secretions, categorized in TCM as phlegm-turbidity and blood stasis. Long-term, the uterus accumulates cold-damp turbidity, decaying and forming damp-heat accumulation. Cold causes stagnation, while damp-heat steams and intensifies stasis. Thus, alternating cold and heat, qi and blood clash, and heat-toxins aggressively attack, ultimately blocking the uterine vessels. Over time, this leads to the formation of masses (commonly known as blood clots). During menstruation, blocked vessels prevent blood flow—"blockage causes pain." Additionally, ischemia due to restricted blood supply triggers strong uterine contractions, forcing stagnant blood and clots into the open uterine wounds—resulting in excruciating pain. Patients may roll on the floor, turn pale, break out in cold sweat, or even faint. Severe pain lasts three to four days, resembling serious illness, requiring several days of bed rest and up to two weeks to recover. Recurrence leads to repeated episodes, depleting qi and blood, damaging Chong and Ren meridians, exhausting liver and kidney yin, eventually causing internal heat. Internal heat combines with damp-heat and toxins, further obstructing vessels, making menstruation difficult and incomplete, leaving residual toxic blood. Ancient wisdom states: "When kidney qi is strong, the Chong meridian flows freely." Weak kidney qi leads to poor Chong-Ren circulation, causing dysmenorrhea. Ye Tian-shi noted: "Since women rely on the liver as their innate foundation, liver yin deficiency allows fire to rise uncontrollably—fundamental deficiency must be addressed immediately by nourishing liver and kidney yin." Modern practitioners believe anemia (including yin deficiency) can cause blood stasis leading to dysmenorrhea. Shanghai gynecologist Cai Xiao-sun said: "Regarding the balance between deficiency and excess in dysmenorrhea, Zhang Jingyue stated: 'Most women with menstrual pain have deficiency, few are purely excess.' This insight is profound. But by the time the condition reaches this stage, it's like a dry riverbed where boats inevitably suffer damage—patients endure severe pain and enter a complex state of mixed deficiency-excess, weakened constitution, and strong pathogenic factors, making treatment extremely difficult."
2. Syndrome Differentiation and Treatment
Chronic damp-heat and toxin accumulation in the uterus, blood stasis obstructing channels, causing pain. Long-term, Chong and Ren meridians are damaged. Depletion of the Jia Gui source leads to liver-kidney yin deficiency, generating internal heat, further obstructing the uterine vessels, resulting in severe, complex, difficult-to-treat dysmenorrhea. Treatment should focus on nourishing yin, resolving dampness, clearing heat, detoxifying, and removing blood stasis.
First, urgently nourish liver and kidney yin to prevent depletion of the Jia Gui reservoir and replenish depleted Chong-Ren blood sea. Clear and resolve damp-heat toxins in the uterus, unblock obstructed blood vessels, repair damage caused by heat-toxins, and restore normal menstruation.
Proposed Basic Formula:

3. Clinical Experience
This condition involves mixed deficiency-excess, severe and complex, primarily due to yin deficiency with damp-heat and toxin-stasis. The self-designed formula heavily uses Sheng Di, Sheng Bai Shao, and Bei Sha Shen to vigorously nourish liver and kidney yin, replenishing the source of blood sea and uterine vessels. Since damp-resolving herbs tend to injure yin, heavy use of nourishing yin herbs is essential to prevent further depletion. Although nourishing yin herbs may retain dampness—typically avoided in dampness treatment—modern TCM practitioners believe combining nourishing yin and damp-resolving herbs is synergistic. Renowned expert Zhao Chaoqin excels in treating yin deficiency with damp-heat using this approach. Once liver-kidney yin is replenished, clearing heat and resolving dampness becomes more effective, allowing blood-stasis-clearing agents to work optimally, accelerating recovery. Large doses of Sheng Bai Shao paired with Gan Cao offer strong antispasmodic and analgesic effects. Chuan Dong Zi and Yuan Hu form the classic Jin Ling Zi San, excellent for relieving various pains—superior to Shi Xiao San—with no foul odor or gastric irritation. Xue Jie, Bai Tou Weng, Dan Shen, Ze Lan, and Shi Yang Quan together enhance blood-stasis removal and pain relief. Notably, Bai Tou Weng is a modern discovery for effectively treating gynecological pain associated with blood-heat and masses. Shi Yang Quan (Bai Mao Teng) has strong heat-clearing and detoxifying properties, plus remarkable pain-relieving effects. Famous physician He Ren of Zhejiang used Xian He Cao combined with Shi Yang Quan to relieve severe cancer pain. Xue Jie not only removes blood stasis and relieves pain but also promotes tissue regeneration—helping repair damaged uterine tissue. Tu Fu Ling, Tu Niu Xi, Ren Dong Teng, and Bai Jiang Cao paired with Pei Lan and Yi Ren form a powerful group for clearing heat, resolving dampness, and dispersing nodules. Removing dampness clears heat and dissipates stasis, cleansing the Jia Gui source, stimulating new blood production, restoring vitality, and naturally curing dysmenorrhea.
The self-designed formula suits Yin Deficiency with Damp-Heat and Blood Stasis dysmenorrhea, showing excellent clinical efficacy.
