🌿 Folk Prescriptions

Dysmenorrhea is a common gynecological disorder, traditionally treated according to patterns such as Qi stagnation and blood stasis, Cold Constriction of 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-like dysmenorrhea or endometriosis with intense pain, specific prescriptions are required. This article proposes the diagnosis of "Dysmenorrhea due to Yin Deficiency with Damp-Heat and Stasis."
This condition commonly affects young women in low-lying, water-rich regions who have histories of poor hygiene during menstruation involving swimming, fishing, working in water, or exposure to rain outdoors. During onset, patients experience tight, hard, burning abdominal pain—worse with heat application. Some may find relief with warmth, indicating Cold Constriction of the Uterus type. There are abundant black, viscous clots differing from Qi-Blood Stagnation type (which features more distension than pain, fewer clots, and brighter color), and distinct from membrane-like dysmenorrhea with sheet-like discharge. This condition results from cold-damp pathogens invading the uterus during menstruation, transforming into heat toxins over time, leading to stasis and damage to the uterine organs—thus complex, mixed deficiency-excess, severe pain.
1. Brief Analysis of Etiology and Pathogenesis
Cold-damp turbidity is inherently yin-cold, sticky, obstructing Qi flow, prone to chronic, entangled progression. Initially injuring Yang, prolonged exposure transforms cold-damp into heat-toxins, damaging Yin. During menstruation, endometrial shedding creates open wounds; cold-damp toxins directly invade these wounds, making the uterus vulnerable. Warm menstrual fluid suddenly encountering cold water causes abrupt constriction of the 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 constriction can trigger pain. From a modern medical perspective: rivers, lakes, and ponds are not only cold and unclean but often harbor various pathogens. When the uterine wound remains open during menstruation and contacts contaminated water, bacterial invasion commonly leads to inflammation—modern medicine identifies this as pelvic inflammatory disease or endometritis, associated with menstruation-related water exposure, unhygienic bathing, or sexual activity. Inflammation typically produces pathological secretions, categorized in TCM as phlegm-damp and blood stasis. Long-standing, the uterus accumulates cold-damp turbidity, which rots and transforms into damp-heat stagnation. Cold constricts the vessels, while damp-heat steams them, worsening stasis over time. Thus, alternating cold and heat, Qi and blood clash, and heat-toxins aggressively attack, ultimately obstructing the uterine vessels. Over time, this forms masses resembling blood clots. During menstruation, blood clots block the passage, obstructing menstrual flow—"no free flow, then pain." Additionally, ischemia due to blocked blood supply causes strong uterine contractions, forcing stagnant blood and clots into the open wounds of the uterus—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 a major illness, requiring several days to bed rest and up to two weeks to recover—yet pain returns with the next period. Repeated episodes severely deplete Qi and blood, damage Chong and Ren meridians, exhaust Liver and Kidney Yin, eventually leading to internal heat. Internal heat combines with damp-heat and stasis, further obstructing vessels, making menstruation difficult and incomplete, leaving residual toxic blood. Ancient wisdom states: "When Kidney Qi is abundant, the Chong Vessel flows freely." If Kidney Qi is insufficient, Chong-Ren circulation becomes impaired, 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. Thus, urgently nourishing Liver and Kidney Yin is essential." Modern practitioners believe anemia (including Yin deficiency) can cause blood stasis and dysmenorrhea. Shanghai gynecologist Cai Xiao-sun said: "Regarding the balance between deficiency and excess in dysmenorrhea, Zhang Jing-yue stated: 'Most menstrual pain involves deficiency; few cases are purely excess.' This is truly insightful. But by the time the condition reaches this stage, it's like a dried-up river where boats inevitably suffer damage. Patients not only endure severe pain but are already in a state of mixed deficiency-excess, with weakened constitution and strong pathogenic factors—complex and difficult to treat."
2. Syndrome Differentiation and Treatment
Stagnant damp-heat and toxin-turbidity coagulating in the uterus, obstructing the uterine vessels and causing pain—long-term damage to Chong and Ren meridians. Depletion of the Jia Gui source (Liver and Kidney Yin) leads to internal heat, further obstructing the uterine vessels, forming a severe, complex, mixed deficiency-excess dysmenorrhea. Treatment should employ methods to nourish Yin, resolve dampness, clear heat, detoxify, and remove stasis.
First, urgently nourish Liver and Kidney Yin to prevent depletion of the Jia Gui reservoir, replenish depleted Chong-Ren blood sea. Clear and eliminate damp-heat toxins from the uterus, unblock obstructed stasis in the uterine vessels, repair damage caused by heat-toxins, restoring normal menstrual function.

3. Clinical Insights
This condition presents complex, mixed deficiency-excess with severe pathology, primarily due to Yin deficiency, damp-heat, and stasis. The self-designed base formula heavily uses Raw Rehmannia, Raw White Peony Root, and Northern Sand-Participating Ginseng to strongly 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 imperative to prevent further depletion of Liver and Kidney Yin. Although Yin-nourishing herbs may promote dampness retention—a general contraindication in dampness treatment—modern TCM scholars note that combining Yin-nourishing and damp-resolving herbs can be synergistic. Renowned expert Zhao Chao-qin excels in managing Yin deficiency with damp-heat. Once Liver and Kidney Yin are replenished, clearing heat and resolving dampness become more effective, allowing stasis-dispersing agents to perform optimally—accelerating recovery. High-dose Raw White Peony Root paired with Licorice offers significant spasmolysis and analgesia. Chuan Teng Zi and Corydalis form a classic pair (Jin Ling Zi San), renowned for relieving various pains—superior to Shixiao San—with no foul odor or gastric irritation. Blood-Resin, Whitehead Herb, Salvia Miltiorrhiza, Eupatorium Fortunei, and Polygonum Multijugum collectively enhance stasis-resolving and pain-relieving effects. Notably, Whitehead Herb is a modern discovery effective against gynecological stasis-heat masses and pain. Polygonum Multijugum (White Hair Vine) has strong heat-clearing and detoxifying properties, plus remarkable analgesic effects. Famous expert He Ren of Zhejiang used a combination of Agrimonia Pilosa and Polygonum Multijugum to relieve severe cancer pain. Blood-Resin not only resolves stasis and relieves pain but also promotes tissue regeneration—ideal for repairing damaged uterine tissue. Earthworm, Trichosanthes Root, Honeysuckle Vine, Houttuynia Cordata, combined with Patchouli and Coix Seed, form a powerful team for clearing heat, resolving dampness, and dispersing nodules. Removing dampness clears heat, dissolves stasis, cleanses the Jia Gui source, stimulates new blood production, restores healthy Qi, and ultimately cures dysmenorrhea.
The self-designed formula is particularly suitable for dysmenorrhea due to Yin deficiency with damp-heat and stasis, yielding excellent clinical results.
