Moxa for Period Pain: TCM Menstrual Cramps
The heat pack is already on the couch before your period even starts. You know the drill — the dull, cold ache low in your belly, sometimes with dark, clotted flow, sometimes with the kind of irritability that shows up days before the bleeding does. Heat helps. It always has. That's not a coincidence.
What the tradition sees
The tradition reads this as cold settling in the lower abdomen — flow that's meant to move getting sluggish and stagnant, the way water slows and thickens when it's cold. Warmth doesn't mask the pain here; it's the actual antidote to the cold that's causing it.
There are two related readings. Cold stagnation in the lower abdomen — cramps that clearly ease with a heat pack, flow that runs dark with clots, a belly that's cold to the touch — is the classic cold-type period pain moxa was built for. Qi/blood stasis with irritability is the stress-adjacent version: breast tenderness and irritability before your period, pain that starts before the bleeding does, best paired with the stress ritual.

Common questions
Can I use moxa on period pain every month, or only sometimes?
The rhythm the tradition gives is daily for 3–5 days before your period starts, then as needed once it does — it's designed to be a monthly ritual, not a one-off.
Is moxa safe for period pain, or could it make things worse?
For cold-type cramps — the kind a heat pack clearly helps — moxa is squarely in its lane. But if your pain is new, severe, worsening month-on-month, or you're bleeding between periods, that's a signal for a practitioner, not a home ritual.
What's the difference between moxa and a regular heating pad for cramps?
A heating pad warms broadly; moxa targets two or three specific points the tradition has used for this exact pattern for centuries — Guanyuan and Sanyinjiao specifically for cold-type cramps.
Can I use moxa if there's any chance I'm pregnant?
No — this is the one absolute line in this practice. No moxa at all during pregnancy, for any complaint, and it applies with particular weight here given Sanyinjiao's role.
Before you start
Pregnancy — the blanket rule: no moxa at all during pregnancy, for home practice, full stop; if there's any chance you might be pregnant, don't moxa this cycle. SP6 (Sanyinjiao) caution: this point is classically contraindicated in pregnancy — skip it entirely if there is any chance you are pregnant. Heavy or flooding bleeding is not a moxa situation — if your flow is unusually heavy, flooding, or bleeding is happening between periods, see a practitioner rather than reaching for moxa. New, severe, or worsening pain — especially pain that's getting worse month-on-month — deserves screening for conditions like endometriosis; that's a doctor conversation, not a home-ritual one. If heat signs are present instead of cold, skip moxa for this pattern. Never use on broken skin, rashes, moles, varicose veins, or numb areas. Never while intoxicated, acutely unwell, or likely to fall asleep mid-session.
