🌿 Folk Prescriptions

Ectopic pregnancy is one of the most common acute abdominal emergencies in obstetrics and gynecology. With advancements in diagnostic techniques, most ectopic pregnancies are now diagnosed early. Conservative drug treatment avoids surgical damage to the fallopian tube structure, thereby maximizing preservation of fertility, especially beneficial for women desiring future childbearing. Recently, the Second Affiliated Hospital of Sun Yat-sen University treated 53 ectopic pregnancy patients using either integrated Chinese-Western medicine or pure Western medicine, comparing efficacy. Results showed that integrated treatment improved effectiveness and shortened treatment duration, with significantly better long-term outcomes compared to the control group, making it a preferred clinical option.
The researchers randomly divided the 53 patients into a treatment group (Group A, 33 cases) and a control group (Group B, 20 cases). Group A received methotrexate (MTX) plus syndrome differentiation-based Chinese medicine. Group B received MTX alone. Results showed that Group A had significantly higher clinical cure rates, shorter time for serum β-hCG to return to normal, and greater reduction in pelvic mass size compared to Group B. Among patients with fertility requirements, hysterosalpingography was performed three months post-treatment. Of the 23 follow-up cases in Group A, 19 (82.6%) had patent contralateral tubes; of the 15 in Group B, 8 (53.3%) had patent tubes. The difference in tubal patency between groups was significantly better in Group A.
MTX is a metabolic inhibitor. Its safety has been confirmed through large-dose treatment of gestational trophoblastic tumors. It does not induce other cancers, nor does it increase subsequent miscarriage or fetal malformation rates, nor does it adversely affect intellectual or physical development of offspring. Some patients experienced mild side effects such as nausea, vomiting, or oral ulcers during medication, which resolved after discontinuation, with no other significant toxicities or long-term adverse effects. Thus, MTX is clinically safe and effective.
The researchers explained that according to traditional Chinese medicine, the etiology of ectopic pregnancy is often related to disharmony of Chong and Ren meridians and qi stagnation with blood stasis. Since the embryo develops abnormally, qi and blood become obstructed. Over time, the vessel walls rupture, blood escapes and flows abnormally, forming blood stasis in the lower abdomen. Prolonged stagnation leads to accumulation and formation of masses (zheng jia). Clinical treatment typically focuses on activating blood circulation to resolve stasis and dispersing masses. In the basic formula of this study, peach kernel (Taoren) and safflower (Honghua) activate blood and resolve stasis; rhizome of curcuma (Sanling) and root of zedoary (Ezhu) break up blood stasis and disperse masses; Corydalis (Yanhusuo), notoginseng (Sanqi), and green tangerine peel (Qingpi) activate blood, stop bleeding, and relieve pain; Tianhua powder (Tianhuafen), centipede (Wugong), and soap pod spine (Zaojiaoci) clear heat, kill embryos, detoxify, and unblock meridians. Modern pharmacological studies show that Curcuma, safflower, centipede, and soap pod spine all possess anti-pregnancy effects, with Curcuma oil showing particularly strong action. Amygdalin in peach kernels hydrolyzes to hydrogen cyanide, which paralyzes the embryonic central nervous system, halting development. Combined with MTX, it interferes with DNA synthesis in trophoblast cells, further promoting embryonic death. Coupled with blood-activating and stasis-resolving drugs, it improves local circulation, inhibits platelet aggregation, and helps dissolve and absorb clots. Thus, it prevents formation of hematoma masses and promotes absorption of existing ones, resulting in significantly better outcomes for pelvic masses in Group A compared to Group B. Blood-activating and stasis-resolving drugs also exhibit anti-inflammatory, antibacterial, and collagen synthesis-inhibiting effects, preventing infection, reducing adhesions, or softening connective tissues. Therefore, tubal patency rates were significantly higher in Group A than in Group B.
