Lesser Yang Shao Yang stage

The Lesser Yang Shao Yang stage is the second of the Six Stages of Cold disease as Cold penetrates into the body.

This ancient theory of disease remains in daily use today, 1800 years after being elaborated by Zhang Zhong Jing.

If you read on, you’ll find that those ancient Chinese knew a thing or two about what it was like to get ill! And they made sense of it in a way we can still use to our great benefit.



Of course over succeeding centuries Chinese doctors learned more about how it worked, culminating in another theory put forward 1500 years later, but that later theory, the Four Levels of Disease, deals not with Cold disease but with the invasion of Heat. The Four Levels theory is more useful for many viruses, including influenza-type illnesses, such as Covid 19, on which we’ve got a page ‘Cope with Fever‘.


If that introduction puts you off, I’m sorry – just trying to be precise! Please read on a bit, and you’ll probably find quite a lot is familiar.

Unlike the third stage, the Bright Yang stage, this Lesser Yang Shao Yang stage is fairly common in Western developed countries where we are either less fit or better at preventing the high fevers of the Bright Yang stage.

In a way, this is a pity. The Bright Yang stage is a strong defence mounted by your body when attacked by Cold disease.

This, the Lesser Yang Shao Yang stage, is not so strong, and can take longer. If it takes much longer, that means more suffering. When it goes on a bit, most people succumb to the blandishments of modern pharmacists and take painkillers.

That means that their ills are usually successfully ‘suppressed’. That’s not necessarily a good thing. Why? Read Suppression.

What is happening at the Lesser-Yang stage?

The Lesser Yang Shao Yang stage mobilises two channels of acupuncture, which are really one long one, called the Lesser Yang Shao Yang channel:

  • the Three Heater channel starting on your fourth finger, next to your small finger, goes up your arm and over the side of your head to your eye
  • from your eye the Gallbladder channel goes over the side of the head next to your Three Heater channel then down the side of your body and legs to your fourth toe, the one next to your smallest toe.
  • Since these two channels are affected, you also get some disturbance in their paired channels and zang-fu organs, the Pericardium and Liver channels.


This long channel is on the side of your body, whereas the Greater (Tai) Yang channels (again made up of two long ones, Small Intestine and Bladder) are mostly on your back, your most Yang area.

In the Greater Yang Tai Yang stage your body kept the invader in the Yang areas  – on your back. Now it’s been forced to permit the invader half-way round to the front, the Yin area.

Half-way in, Half-way out

So your body is still fighting but the invader is half-way through the door. As the door swings one way or the other, the invader is pushed out or forces its way further in.

Of course, these are figurative: pictures to help us understand. There isn’t a great big bogeyman, Wind-Cold, that you can see. But your body behaves as if, fighting this invisible opponent, it is trying to keep it away from the centre.

The symptoms, such as the bitter taste, fullness under the ribs and blurred vision come from these two channels, particularly the Gallbladder channel, which plays a large part in maintaining vision and courage: in this state you aren’t feeling very courageous.

Symptoms of Lesser Yang Shao Yang stage

The main feature of this Lesser Yang Shao Yang stage is that the body and the wind-cold are almost evenly matched, so at times one is winning, at times the other.

Alternation of States in this Lesser Yang Shao Yang stage

This means you get an alternation between keeping the disease process on the outside and letting it in, as your body strives to keep it out. It’s like alternating between the first two stages, above.

When it’s on the outside, you get shivering. When it’s on the inside, you get fever.

  • Two alternating states: feeling cold and shivering 
  • versus… 
  • feeling hot and feverish. Unlike in the Greater Yang stage, you don’t get both shivering and feeling hot at the same time. Instead, here they alternate.
  • If you don’t actually have a fever as measured by a thermometer when you are feeling hot – during the hot alternations – you may also not actually feel objectively hot to someone touching you.
  • taste may be bitter (from the Gallbladder in excess)
  • full distended feeling under the ribs (hypochondria, the area ‘ruled’ by your Liver)
  • vision can be blurred (because Liver and Gallbladder can’t maintain good Qi and Blood to the eyes)
  • no desire to drink 
  • no desire to eat
  • nausea, possibly vomiting: often stomach ache (because Liver ‘attacks’ the Stomach)
  • irritable and mentally disturbed: can prevent sleep (if your Pericardium is disturbed)
  • your heart-beat may be irregular (if your Pericardium is also affected)
  • Tongue: often has a coating, thin and white or a mixture or white and yellow: may be on one half only: sides may be a bit redder than the rest of the tongue
  • Pulse: thin and wiry

What can YOU do at this Lesser Yang stage?

Don’t let yourself get cold and do keep warm. That’s about it. (What about a hot  bath? Stay in it until you start to sweat slightly. But don’t stay in it for more than 15 minutes even if you haven’t started to perspire. Instead, get into bed with a hot water bottle or hot bean-bag – but don’t burn yourself! And lots of bedclothes. Try to sleep for some hours.)

At this Lesser Yang Shao Yang stage, I’m not sure vigorous physical exercise is so helpful because your body’s energy is already depleted and only just holding its own.

Making your body take vigorous exercise, to the point where you sweat, may weaken it further, allowing the invader to push in more. Sleep is a better suggestion. Lots of rest.

However, you must keep your energy up so you should try to eat and drink small amounts, even if you don’t relish them.

  • Food and drinks should be warm
  • Food should be easily digested and nutritious, so warm rice congee is good: even better are warm vegetable soups and, if you are not vegetarian, chicken or beef consommé.
  • Ginger is excellent to help you digest food
  • There is a theoretical suggestion that warm, weak, cider vinegar might assist your body here. You don’t need much, just a few drops in warm water. However, I haven’t tested this myself on the very few (I’m glad to say)  occasions I’ve been in the Lesser Yang stage: I just stayed in bed and let my body sort it out.

What would your acupuncturist do for this Lesser Yang Shao Yang stage?

Acupuncture has been used to treat this for 1800 years. Points along the Lesser Yang Shao Yang channels (Gallbladder and Three Heater) would mostly be used, the aim being to release the invader outwards by harmonising the channel. For example, TH 5, TH 6, TH 17, GB 34, GB 41, Du 13.

There is an ancient herbal recipe that is often very effective: Xiao Chai Hu Tang.

What happens if the Invader gets past the Lesser Yang stage?

In that case, the disease has penetrated past your first two Yang defences and is now at the Bright Yang Yang Ming stage on its way to your Yin defence area, ie the Greater Yin stage. However, the last of these Yang defences (ie the Bright Yang Yang Ming stage) is a strong one.
