When period pain needs a doctor
Period pain (dysmenorrhea) is common and is often a normal part of the cycle, when the womb tightens during a period. [1] But the NHS lists conditions that can cause it, including endometriosis, adenomyosis, fibroids and pelvic infection. [1] Get an urgent medical review if pelvic or period pain is severe or worse than usual and painkillers have not helped. [1] See a doctor if periods become more painful, heavier or irregular, or if you have pain during sex, bleeding between periods, weight loss or a swollen tummy. [1] In the US, call 911 for an emergency.For everyday guidance see period pain and menstrual cycle health. The NHS suggests heat, gentle exercise, massage and painkillers such as paracetamol or ibuprofen, and doctors may recommend stronger anti-inflammatory medicines or a TENS machine. [1]
How TCM explains period pain
In TCM, painful periods are described using ideas such as stagnant qi or blood, cold, or deficiency. These are traditional frameworks, not diagnoses a scan can confirm; see TCM gynecology. What follows is only what trials measured.Chinese herbal medicine
A Cochrane review of 39 trials (3,475 women) looked at Chinese herbal medicine (CHM) for primary dysmenorrhea, meaning period pain with no identified pelvic disease. [2] Results compared with placebo were unclear because the data could not be combined (3 trials). [2] Against pharmaceutical drugs, CHM did better for pain relief in 14 trials (relative risk 1.99). [2] The authors called the evidence "promising" but limited by poor methods and small trials. [2]That review is from 2008, so newer trials are not included, and I did not find a newer Cochrane update. Most comparisons were herbal mixtures versus drugs or other herbal products, which are open to expectation effects and publication bias; see publication bias in Chinese trials. Label: promising but limited.
The published review does not name a single best formula, and this page does not give doses or recipes. Formula names such as Xiao Yao San are covered separately.
Acupuncture and acupressure
| Comparison | What the 2016 Cochrane review found | Strength of evidence |
|---|---|---|
| Acupuncture vs sham | 6 trials, inconsistent; the one trial at low risk of bias in all areas found no difference at 3, 6 or 12 months. [3] | Insufficient evidence |
| Acupuncture vs NSAIDs | Pain relief favored acupuncture in 4 trials (odds ratio 4.99), but the evidence was low quality and the trials varied too much to pool pain scores. [3] | Low-quality evidence |
| Acupressure vs sham | Two studies reported a benefit of 1 to 3 points on a 10-point scale; data were unsuitable for pooling. [3] | Low-quality evidence |
The review included 42 trials (4,640 women) and concluded that there is insufficient evidence to say whether acupuncture or acupressure work for primary dysmenorrhea, citing risk of bias, poor reporting and probable publication bias. [3] An earlier 2011 Cochrane review of 10 trials was more positive ("acupuncture may reduce period pain") but called for better trials; the 2016 review is larger (42 trials) and reached a more cautious conclusion. [4] For how needling and pressure are done, see acupuncture and acupressure.
Frequently asked questions
Is there a Chinese herb that cures period pain?
No. A Cochrane review called the evidence for Chinese herbal medicine promising but limited by poor trial quality. [2]
Does acupuncture work for period pain?
Unclear. The 2016 Cochrane review found insufficient evidence, and the one low-risk-of-bias sham-controlled trial found no difference. [3]
Is acupressure safe to try?
No acupressure studies in the review reported adverse events, but the evidence was low quality. [3] See acupressure for cautions.
When is period pain not normal?
When it is severe or worse than usual, not helped by painkillers, or comes with heavy bleeding, bleeding between periods or pain during sex. [1]
Can I use herbs with ibuprofen?
Ask a pharmacist. Herbs and drugs can interact, and NCCIH advises talking to a health care provider before using TCM herbal products. [5]

Safety
- Herbal products can be contaminated or mislabeled; NCCIH reports Chinese products with undeclared drugs, heavy metals and pesticides. [5] See Chinese herbal products: quality and interactions.
- Tell any practitioner if you could be pregnant, take blood thinners or have an IUD, which the NHS notes can itself cause period pain in the first 3 to 6 months. [1]
- If you take a blood thinner, ask a pharmacist before using any herbal product.
- Keep taking prescribed medicines unless your prescriber tells you otherwise.
