The kidneys are located on the rear wall of the abdomen in the small of the back on either side of the vertebral column and have many different functions. The meridians (energetic pathways) of the kidneys pass into the ears.
The kidneys store jing (sexual essence, DNA). Jing is the fundamental, material substance of life governing birth, growth, development and reproduction It is stored in the left kidney as kidney yin and transformed by the right kidney (kidney yang, gate of fire) into the marrow, bones, brain, spinal chord, sex organs, head hair, teeth (excess of bones) and original chi (stimulus of all organ function). Jing also governs will power. The amount of jing is fixed at birth, and starts to decline after sexual maturity. It is the fountain of youth when full, and the harbinger of old age, disease when less, declining. Protein and fat build and fuel jing.
The kidneys regulate electrolytes (positive and negative ions), pH, acid and alkaline balance. The pH scale ranges from 1 – 14. A pH of seven is neutral. Below seven is acid, above, alkaline. Normal body, blood pH is approximately 7.3. Anything above (alkalosis) or below (acidosis), in the extreme sickens.
The kidneys filter the blood removing and combining nitrogenous (protein and fat) wastes, urea with water into urine, sent down via ureters to the urinary bladder for temporary storage and eventual excretion via the urethra. The kidneys control the urinary bladder, urination and elimination.
The kidneys are a function of diet, lifestyle. Too much or too little protein and fat, excessive sex, caffeine, coldness, immobility, sedentary lifestyle, excessive sitting, lying down, and or chronic illness tend to weaken the kidneys, bones, sex organs, etc. Protein and fat build and fuel blood, jing kidneys, etc.
Low protein and low fat diets, in the extreme, tend to thin and weaken the blood, which in turn, thins and weakens jing, hair, teeth, bones, etc. Too much protein, fat, in addition to alcohol, smoking and caffeine also accelerates the consumption of jing.
Excessive sex, masturbation (daily), caffeine, alcohol, smoking, stimulant drugs, bulimia, overwork, heredity and or living in an excessively hot, dry climate increase, accelerate consumption, burning of jing. When jing declines, the aging, drying, thinning and weakening process begins. You can live fast, die young or slow down, conserve jing and live longer.
Excessive sex, masturbation is especially weakening for men. Orgasm, ejaculation produces a great loss of energy via a loss of essence, jing (contains large amounts of protein and fat) generally causing a loss of consciousness after orgasm. Eastern philosophies advise the man to start but not finish (ejaculate, orgasm) to not only conserves jing but also extend lovemaking. Give up the small (orgasm) for the greater (longer lovemaking, healthier life). The less you ejaculate the stronger and longer you live, which is why many spiritual disciplines advocate celibacy. Celibacy also allows one to direct energy inward, upward into the higher chakras, spiritual energy centers, instead of down and out the lower chakras.

Kidney pathologies are defined in terms of yin and yang. Kidney yin (jing) builds and moistens all yin (liver yin, heart yin, lung yin, etc), while also building and fueling kidney yang (fire). Kidney yang fuels all yang, function (digestion, respiration, circulation, reproduction, etc.) and automatically declines, becomes deficient when kidney yin, jing declines. Kidney yin and yang are never in excess, only deficient, as jing naturally declines with age, after sexual maturity (varies according to the individual). Kidney pathologies, in general are stage 6 or higher. The following are symptoms of kidney yin deficiency.
Kidney yin deficiency Stage One
1. Dry mouth at night Long-term kidney yin deficiency, blood, protein and fat deficiency and or excessive heat (too much protein, fat, alcohol, caffeine and smoking), tends to cause heat, dryness, especially in the extremities, head, arms and legs, during the evening and or periods of inactivity. Dry mouth and throat, during the night is a cardinal kidney yin deficiency symptom
2. Night sweats Deficient yin (jing, blood) fails to control0 cool and moisten yang, fire, causing the body to temporarily overheat, perspire during the night.
3. Malar flush is partial facial flushing. Kidney yin, jing deficiency cannot fully control, contain energy, fire causing it occasionally rage, flash out of control producing partial (deficient) flushing as opposed to total flushing (entire face red). Excess heat (too much building) causes excess heat. Deficient heat causes deficient, temporary heat.
4. Insomnia (light and dreamy) The shen, spirit sleeps in the heart (blood rich organ anchors, holds the spirit). Kidney yin, blood, protein, fat, jing deficiency tends to weaken and dry the heart (in addition to everything else) while overheating the body, causing the spirit to rise up into the head, brain, stimulating thinking, dreaming.
5. Urinary difficulties Kidney yang heats the bladder, thinning its fluids making them easier to pass. When jing declines, kidney yang, fire also declines increasing and thickening water in the bladder making it more difficult and painful to pass. Yin fuels yang.
Stage Two. Chronic kidney yin deficiency
6. Dry skin, nails, hair, eyes, secretions, etc Long-term kidney yin (jing, blood) deficiency dries the skin, hair, nails, etc.
7. Mental problems (poor concentration, loss of memory, etc) Long-term jing, blood deficiency thins and weakens the marrow, brain. Dizziness, vertigo
8. Restlessness and or irritability Yin deficiency tends to cause deficient heat, over stimulation of the brain. Yang (fire, energy) no matter how weak is always moving. Energy moves. Its movement is temporary and not long lasting as the cause is deficiency. Excessive restlessness would require excessive energy, fuel, high protein, high fat, spices, coffee, smoking, etc.
9. Dizziness and vertigo Severe blood, jing deficiency, poor circulation and or sudden excess heat via diet (caffeine, alcohol, smoking, etc.) or climate (hot, dry) tends to dry and weaken the brain causing it and the body to become dizzy, lose consciousness, control temporarily, causing the body to sway, like fire. 10. Tinnitus (ringing in the ears) The kidneys open up into the ears. Kidney yin deficiency tends to create a soft ringing as opposed to a loud ringing, generally a symptom of excess heat in the liver.
11. Weak bones and teeth Jing is the material foundation of the bones, teeth and hair.
12. Nocturnal emissions The kidneys control the sexual organs.. Deficient kidney yin weakens, lessens kidney yang, holding power, causing leaking during the night (nocturnal emissions).
Kidney yang heats, stimulates, supplements all function, yang: digestion (spleen), respiration (anchors the breath, inhalation), elimination (bladder, orifices of elimination), circulation (heart) and reproduction (transforms jing into ovum, sperm). Jing, blood deficiency, old age, poor diet, excessive sex, alcohol, caffeine, drugs and kidneys yin deficiency drains, weakens kidney yang. Kidney yin, jing fuels kidney yang.
Kidney yang deficiency Stage One
1. Coldness in the back and knees Kidney yang warms the bones, back, knees.
2. Sore, weak lower back The kidneys are located in the lower back. Kidney yang (chi) holds the bones in place. Deficient kidney yang causes pain, weakness and coldness in the lower back. Cardinal symptom
3. Abundant, clear urination Kidney yang heats the bladder, thins the urine. Weak kidney yang cools the bladder increasing water, urine and the need to urinate.0
Stage Two
4. Bright, white complexion Kidney yang supplements heart and lung yang. Chronic deficient kidney yang weakens the lungs, heart, reducing circulation, blood flow to the head, face producing a bright, white complexion (cold). Blood is red (hot).
5. Shortness of breath Kidney yang anchors (pulls in) the breath, Chronic kidney yang deficiency weakens, decreases the inhalation.
6. Weak legs The kidneys rule the bones, legs
7. Loose stools at daybreak Deficient kidney yang weakens digestion, spleen yang, fire.
8. Premature ejaculation Kidney yang (chi) holds. Deficient kidney yang tends to cause premature ejaculation (lack of holding).
9. Impotence Kidney yang moves and holds blood in the penis. Deficient kidney yang causes impotence.
10. Chronic vaginal discharge Kidney yang heats the body. Weak kidney yang cools, moistens and thickens fluids in the uterus, vagina into clear or white mucous discharges.
11. Edema in the legs and ankles Kidney yang controls water metabolism. Water increases, and tends to overflow into the legs and ankles when kidney yang is weak.
12. Prolapse of the uterus Kidney yang supports spleen yang, holding. Chronic kidney yang deficiency weakens spleen yang, holding causing the uterus to sink, prolapse.
13. Infertility in women Kidney yang transforms jing into ovum, moves the egg (ovum) through the ovaries and fallopian tubes into the uterus. Kidney yin deficiency decreases transformation, movement of the egg, fertility.
14. Tongue is pale, swollen and wet. Kidney yang heats the body, dries excess fluids and supports heart yang, circulation. Deficient kidney yang burns less fluids and moves less blood causing the tongue to become pale (blood is red), cold, swollen and wet.
The kidneys, jing are nourished by blood, protein and fat (especially red meat), black foods (black beans, black fungus, black sesame seeds, black dates, rhemannia, etc.) and warmth (protein, fat, cooked foods, etc.). Cold temperatures (winter, air condition, swimming in cold water, etc.), cold drinks (juices, sodas, ice water) in excess, tends to chill, shock and weaken the kidneys. This is one reason why in some cultures women wrap, insulate their midsection, lower abdomen with an extra layer of clothing, to keep cold out, while heat, energy in. It is also the reason why most foods are cooked, to not only aid digestion, but also increase body heat. This does not mean that vegetables should be overcooked, soft, mushy just cooked, lightly steamed, boiled, crunchy.
