Period pain is one of the most common reasons women seek out acupuncture — and one of the most rewarding conditions to treat.
Whether your pain has been dismissed as “just cramps” or you’ve been managing it with ibuprofen for years, there are effective natural options that go far beyond pain relief in the moment.
This article explains what dysmenorrhea is, how Traditional Chinese Medicine understands and treats it, what the current research shows, and how Drew works with patients dealing with painful periods at his Toronto Danforth clinic.
What is Dysmenorrhea?
Dysmenorrhea is the clinical term for painful menstruation — cramping, pelvic pain, and discomfort that occurs during or just before the menstrual period. It is one of the most prevalent gynecological complaints worldwide, affecting an estimated 45–95% of menstruating women to some degree.
There are two types:
Primary dysmenorrhea refers to menstrual pain without an identifiable underlying condition. It is caused by an excess of prostaglandins — hormone-like compounds that trigger uterine contractions during menstruation. When prostaglandin levels are high, contractions become more intense and prolonged, reducing blood flow to the uterus and causing the characteristic cramping pain.
Secondary dysmenorrhea is pain caused by an underlying reproductive condition — most commonly endometriosis, but also fibroids, adenomyosis, or pelvic inflammatory disease. Treatment of secondary dysmenorrhea involves addressing both the pain and the underlying condition.
A Special Note on Endometriosis & Infertility
Endometriosis — a condition in which tissue similar to the uterine lining grows outside the uterus — deserves particular attention in any discussion of dysmenorrhea. It is one of the leading causes of painful periods and one of the most underdiagnosed conditions in women's health. The average time from first symptoms to diagnosis is still measured in years, not months.
The connection to fertility is significant. According to the World Health Organization, 25–50% of women with infertility have endometriosis — and women with endometriosis face an estimated two to four times greater risk of infertility compared to the general population. If you are experiencing painful periods alongside difficulty conceiving, endometriosis may be a factor worth investigating with your medical team.
TCM treatment cannot diagnose or cure endometriosis — but it can meaningfully address the pain, reduce inflammation, support hormonal balance, and complement any medical treatment you are receiving. Many of Drew's fertility patients also present with endometriosis, and supporting both concerns simultaneously is a regular part of his clinical work.
How Does Traditional Chinese Medicine Understand Painful Periods?
In TCM, menstrual pain is almost always understood as a problem of obstruction — the free flow of Qi (energy) and Blood through the uterus is being disrupted, causing pain. The principle is simple: where there is free flow, there is no pain. Where there is obstruction, there is pain.
The specific cause of that obstruction varies from person to person, which is why two women with equally painful periods may receive quite different treatments. The three most common TCM patterns seen in dysmenorrhea are:
Blood Stasis The most common pattern. Blood is not moving freely through the uterus, leading to clotting, dark or purple menstrual blood, fixed stabbing pain that worsens with pressure, and relief once bleeding begins. This pattern is frequently seen in endometriosis.
Cold in the Uterus Cold — from external exposure (cold weather, cold foods) or constitutional tendency — constricts the uterine vessels and impairs circulation. Symptoms include cramping pain that improves with heat, pale or dark blood with clots, cold extremities, and a preference for warmth. Moxibustion is particularly effective for this pattern.
Liver Qi Stagnation Emotional stress, frustration, and tension cause the Liver’s free-flowing function to become constrained, affecting the smooth movement of Qi through the pelvis. Symptoms include distending pain that moves around, breast tenderness, irritability before the period, and pain that improves once flow begins. This pattern is commonly seen alongside the others.
It is worth noting that many patients present with combinations of two or more patterns — and TCM diagnosis accounts for this complexity by tailoring treatment to the individual rather than applying a standard protocol.
Treatment Options
Clinical Acupuncture Acupuncture is the cornerstone of TCM treatment for dysmenorrhea. Points are selected based on your specific TCM diagnosis — not a generic period pain protocol. Treatment aims to move Blood and Qi, reduce uterine contractions, regulate prostaglandin levels, and activate the body’s natural pain-relieving endorphin response. For best results, treatment is recommended in the week before your period, during the period itself if pain is severe, and regularly between cycles to address the underlying pattern.
Chinese Herbal Medicine Herbal medicine is a powerful complement to acupuncture for dysmenorrhea — particularly for Blood Stasis and Cold patterns where the underlying disharmony needs consistent treatment between cycles. Formulas are prescribed based on your individual TCM diagnosis and adjusted over time as your pattern shifts. A 2025 systematic review and meta-analysis found that combining acupuncture with herbal medicine significantly improved pain scores, uterine artery blood flow, and overall effectiveness rates compared to acupuncture alone. clinicaltrials
Dietary Guidance Food is medicine in TCM. Dietary recommendations for dysmenorrhea typically focus on warming foods that support circulation, reducing cold and raw foods that can aggravate Cold patterns, and anti-inflammatory eating principles that address the prostaglandin excess driving primary dysmenorrhea. Specific guidance depends on your TCM pattern.
TENS Therapy Transcutaneous electrical nerve stimulation — applied to acupuncture points or directly over the lower abdomen — can provide meaningful pain relief during the menstrual period itself. Drew has put together a practical video guide on using a TENS unit for dysmenorrhea relief at home. CLICK HERE
What Does the Research Say?
The evidence base for acupuncture in dysmenorrhea is substantial and growing.
A systematic review and meta-analysis examining 13 randomized controlled trials with 675 participants found that acupuncture and moxibustion were significantly more effective than control treatments in managing primary dysmenorrhea, with meaningful reductions in pain scores across multiple validated measures. PubMed
A comprehensive network meta-analysis published in 2025 — searching 10 databases including Cochrane, PubMed, and Embase, covering studies through November 2024 — compared the efficacy and safety of multiple acupuncture-related therapies for primary dysmenorrhea, finding consistent evidence of benefit across acupuncture modalities. clinicaltrials
Research on auricular acupuncture specifically for dysmenorrhea has also shown promising results, consistent with the broader evidence base for acupuncture point stimulation in menstrual pain management.
The mechanisms are well understood from a biomedical perspective: acupuncture reduces prostaglandin levels, increases endorphin release, improves uterine blood flow, and modulates the pain signalling pathways involved in menstrual cramping.

Drew’s Experience & Additional Training
Dysmenorrhea is an area Drew has pursued with particular depth throughout his clinical career. In addition to 25 years of treating painful periods in practice, Drew has:
- Delivered a continuing education seminar for Naturopathic Doctors on the topic of dysmenorrhea — bringing a TCM perspective to the naturopathic community
- Developed an online course on dysmenorrhea through his Acupuncture Masterclass platform at acupuncturemasterclass.com — designed for acupuncture students and practitioners who want to deepen their clinical knowledge in this area
This depth of training means that when you come to see Drew for painful periods, you are working with someone who has thought carefully about this condition — not just in the treatment room, but in the classroom and the research literature.
