Tension builds slowly, so herbalists gave it time
Stuck Liver Qi, in the old picture, doesn't come from one bad day. It's weeks of pressure: the sighing, the snapping at people you love, the warm flush when someone moves your mug. Herbalists didn't expect a formula to undo that overnight, so Jia Wei Xiao Yao San was traditionally taken steadily, often across more than one cycle, and practitioners often kept people on it for a good while. Sixty days is a sensible first stretch. It's long enough to notice the week before your period, and how your evenings go, twice over.
Got a mad patch coming? New job, moving house, the run-up to the change, that kind of thing. Six bottles sees you through it, and you won't be scrabbling to reorder halfway. Low mood or anxiety a big part of it, though? Then go and see your GP as well. Please.
10 days a bottle, about 60 days in all
Sixty days, two cycles, one note a day
Bottles 1–2
Days 1 to 20
Six a day, half in the morning, half at night. We'd scribble a line every evening too (how's the mood, the temper, did you run hot, what day of the cycle is it).
Bottles 3–4
Days 21 to 40
Usually a full cycle in. Look back at the week before your period in your notes. That's the window herbalists paid most attention to.
Bottles 5–6
Days 41 to 60
Round two. How's it stacking up against last month? Feeling more worn out and wound up than hot these days? Then a herbalist might well swap you to plain Xiao Yao San.
If you're expecting, trying to be, or feeding a baby yourself, chat to your GP before you start, honestly. There's dong quai in it, and that doesn't get on with warfarin or other blood thinners. On any regular medication at all? Have a word with your GP or pharmacist first. We'd rather you did.
Choosing between them
Tension, heat or midlife? Three close neighbours
There's a lot of overlap here. So how did herbalists pick? They'd ask what was leading the dance, stuck Qi or heat, and whether Yin had started running low.

Jia Wei Xiao Yao San
Stuck Liver Qi that's gone hot, and a Spleen that's tired out. Think wound up and pink in the face, fuse about an inch long, evenings you can't settle, usually round the cycle.
The brisk mover
Chai Hu Shu Gan San
When the tension's moved into the body. Ribs feel tight, you sigh all day, and stress goes straight to your stomach. It's more about moving than nourishing (and it has no cooling herbs).
See Chai Hu Shu Gan SanMidlife Yin
Geng Nian An
Made for the change. Kidney Yin's said to be thinning out by then, so the warmth sneaks up at night. Rehmannia at its heart, and calming, not really a stuck-Qi formula at all.

Anna T., verified buyerI have been using these for a couple of weeks and have already noticed a big difference in mood, positively. Am ordering another bottle to continue on.
Freya E., verified buyerJia Wei Xiao Yao San: your questions
Why do people bring up Jia Wei Xiao Yao San when they talk about PMS?
History, mainly. Ask around about PMS and its name comes up a lot! That's because when the days before a period left someone tense, ratty and hot, it's the pot the old herbalists went for. That's its history, not a treatment claim. PMDD, low mood, or anything that's getting in the way of your life should go to your GP.
Is it one for men too?
Yes, though you'd never guess it from the shelf. Stuck Liver Qi with heat isn't a women-only pattern, and herbalists have given it to men who are wound up, short-tempered and running warm. Why's it got a name in women's health, then? Because a monthly cycle shows the pattern up so clearly, that's all.
Anything herbalists said to do day to day?
Get your Qi moving, basically. The theory goes that stress jams it up and moving about loosens it again, so a good stomp round the park, fresh air, and saying what's bugging you instead of stewing on it. Alcohol and very spicy food were said to add heat, which is exactly what the two extra herbs are there to cool, so go easy on both.
Can I take it with Gui Pi Tang?
Some practitioners do use the two side by side, when tension and heat come with real tiredness and poor sleep. Still, do check with a herbalist before you put them together. They're each a whole formula, and they've both got dong quai in, which really matters if you're on any medication.
So how long will the 6 pack keep me going?
Sixty days, at six a day. Same eight herbs as the single bottle, sixty tablets in each of the six, and for most women that's two cycles' worth. Pop the ones you haven't opened somewhere cool and dry. Oh, and glance at the best-before on each as you get to it.
