Chinese Organ Networks: Liver

And so we come around to the Liver.  The Liver is a frickin' doozy.  Enough so that I'm actually procrastinating jumping into the meat of the matter, because I hardly know where to start.  This is an organ system rife with rich associations and layers of meaning that seem to shoot out in all directions like fresh green tendrils in springtime.  Stubbornly spreading up and out, against gravity, persevering against tough odds--namely the laws of physics, which luckily seem not to apply to living things.  Or rather, life finds the loopholes and bends said laws to its own benefit and makes of Newton and Descartes a gleeful mock.

As usual, the macrocosmic position of the organ reveals much of its nature.  We saw how in a sense the Gallbladder marks the beginning of the new year, as yang (light, warmth) makes its return--as yet unfelt, perhaps, but influential all the same.  To the Liver falls the task of continuing the what the Gallbladder has initiated.  The Gallbladder's job was romantic--the spark in the dark, setting things off with a little explosion; the Liver's is decidedly less so.  The Liver doesn't take that critical first step back towards the light, but rather the equally critical second step.  It plods forward, against the flow, against gravity.  It perseveres.  Its animal symbol is the ox: the creature best suited to long, hard labor.  The ox wants and needs something to push against.

Labor...pushing...if this is all sounding suspiciously feminine, it's not a coincidence.  The Liver is the organ most closely associated with womanhood, most obviously through the blood, which the Liver is said to store.  "Women are blood, men are qi," goes a Chinese medicine saying.  But we are getting ahead of ourselves.  We aren't finished with the ox.  Could there be a more specific connection between oxen and women?  Here's a hint: take a look at a picture of an ox head or skull.  Georgia' O'Keeffe was on top of this one (though she chose a ram, the effect is much the same.)  The relation of head and horns is strikingly similar to that of womb and ovaries via the Fallopian tubes.  Women, in some sense, have the power of oxen: to push, to persevere, to plod forward and continue the endless work.  Masculine energy is more apt to come in bursts; men are often good initiators and warriors, hunters, whereas women keep the ball rolling.  Hormonally, women may be better suited to traditional "women's work"--not just the obvious maternal activities but such slow, methodical, careful work as weaving, spinning, seed-sorting, knitting.  It's not just a matter of culture.  Women are rich in blood, which in Chinese medicine also means certain hormones, and this hormonal reality shapes much of physical, psychological reality.

Of course it's not just women who benefit from the ability to push, to go against the flow.  This type of sustained work is at the heart of self-cultivation practices, from martial arts to meditation and everything in between (Tai Qi and Qi Gong and genuine Hatha Yoga tend to fall towards the center of this spectrum).  The Chinese sagely ideal is of wu wei, effortless action; but in order to achieve such a state of skill it is necessary to train intensively.  The archetypal Zen master who flows so artfully through life does not achieve their mastery except through rigorous training.

There's yet another feminine connection to be made.  The Liver's cosmological time is most of January and the beginning of February, a period which overlaps (even if it doesn't completely correspond) with the Western astrological sign of Aquarius.  At first glance the associations are disparate; the Liver with blood and femininity and Aquarius with water, creativity, prophetic change.  Symbols take us deeper, however.  The traditional shorthand for Aquarius is a double squiggle, like two letter M's nested on top of one another.  Now it is an interesting fact that the word for "mother" in virtually every language begins with or contains the "m" sound.  mother, mama, mom, mu, ma, aama, maman...there are probably exceptions, but I can't come up with any.  Infants seem hardwired to make the "m" sound in relation to their mothers.  The letter M even look like a couple of a pair of bent legs, spread, as in a reclining birthing position.  Aquarius is also classified as an air sign; we'll soon see how air or wind relates to the Liver.

That's two liver-blood-femininity strings of association so far.  We've momentarily come up for air; time now to dive down and pull up one more set.  The Liver stores the blood, has everything to do with this vital substance.  What is the blood, on the level of micro-macrocosmic correspondences?  It is our vital water, our veins and arteries like rivulets and streams and great rivers.  They all flow into the sea, our great reservoir of blood, the Liver.  Another way to look at it: evolutionarily we come from the ocean.  Primitive sea creatures need no closed circulatory systems, but when we crawled out of the watery depths, we needed a way to bring some of that ocean with us.  The blood, and especially the Liver's blood reservoir, is that oceanic remnant.  It's noteworthy, too, that we're not talking about fresh water here.  The ocean is salty, and so is the blood.  Nor is the saltiness of either composed of simple sodium chloride, though that is the most prominent component of ocean and blood salts by weight.  The ocean contains hundreds of trace minerals in solution, and so does our blood.  Though nutritional science hasn't uncovered a physiological need for every such mineral, more and more are being found to be essential to health.  This is why unrefined sea salt (including salt mined from ancient sea beds) are so critical to health.  Remove all those essential trace minerals, and you compromise the quality of your internal ocean.

Another conceptual leap: the Liver and blood relate directly to Wind and the nervous system.  The most basic connection is to be found in the trigram Xun, The Gentle or Wind or The Subtle.  It shows a single yin line penetrating up through two steadfast yang lines.  It is yin moving upwards, and represents the pervasiveness of subtle influence.  This is how a breeze operates: it is gentle, but if it maintains a consistent direction it can be powerful in the long run.  But Xun is also a symbol for Wood, the upward growth of springtime.  It is the yin aspect of Wood, just as the Liver is the yin Wood organ (and the Gallbladder yang Wood, as represented by the trigram Zhen, with one yang line thrusting up below two of yin).  Wind, the force of movement and communication, is related to springtime.  Spring is, after all, the time when things are shaken up, when the "winds of change" blow.  That, roughly, is how the physiological force of Wind or Air is related to the Liver.  (An interesting contrast with Ayurveda here; in that system, Wind or Vata is more associated with the large intestine, and while it is closely related to the nervous system, the concept of blood and the liver is largely separate.  At least as far as I understand it.)

So the Liver is responsible for Wind, for proper movement.  Movement of what?  Of qi, primarily.  Of subtle energy, including perhaps the electro-chemical impulses that are the language of our nervous system.  Now it may be less surprising that trace mineral deficiencies have been implicated in a number of growing disorders including ADD and ADHD.  These can be viewed in terms of Wind; hypermobility; an ungrounded and in some sense overactive nervous system.  When our blood is not well fortified with the natural ocean's mineral spectrum, our Wood and with it our Wind go out of whack.  In our terms, its a Liver problem.

We've yet to look at the Confucian 12 officials system.  In it the role of the Liver is clear cut: it is the general.  It commands, strategizes, schemes.  Physiologically, the little-L liver sorts out thousands or millions of chemical reaction pathways, sending this here and that there and generally ironing out an operating plan for the Gallbladder to execute.  The Liver is resourceful.  As a commander it wants to win; it strives to live.  See?  It's not just the Chinese language that contains plenty of forgotten symbolic resonance.  The liver is the only organ that is capable of fully regenerating itself from a small fraction.  It's that (re)generative power of Wood.

Finally, the herbal side of the story.  The herb that best represents the upward and outward exuberance of Wood is none other than the familiar cinnamon (Chinese Gui Zhi (twigs) or Rou Gui (bark)).  Cinnamon was anciently classified in the Tang Ye Jing as a "Wood within Wood" herb, meaning that it is the essence of Wood.  Although modern TCM likes to treat the liver in terms of suppressing flaring liver yang with cold herbs and smoothing out the liver qi with herbs like Bupleurum (Chai Hu), much modern Liver pathology has more to do with cold in the blood.  Here our internal ocean gets frozen over, leading to blood deficiency and stasis, with signs like cold extremities, menstrual cramps with clotty bleeding, and sexual frigidity.  Bulldozing through the ice with qi-moving herbs won't work; we have to melt the ice.  Cinnamon gets into the blood layer (Jue Yin) and does just that, especially when combined with the star blood herb Dang Gui (Chinese Angelica).
