The way our body is constructed is to contain an energy system of meridians, other than the known systems such as the lymphatic system, nervous system, etc.
Those meridians are channels not unlike blood vessels, but with energy flowing through instead of blood. They affect the body and the substance exchange in it.
There are a total of 12 meridians, belonging to every major organ. These are the lungs, large intestine, stomach, spleen, heart, small intestine, bladder, heart area, kidney, duodenum, gallbladder and liver meridians. According to yin-yang, they are divided in six yin and six yang meridians. The yin meridians belong to the organs which collect, storage and process substances and energy: the liver, lungs, spleen, heart, kidney and heart area.
The yang meridians include the organs which exchange and excrete substances and energy: the colon, stomach, small intestine, bladder, duodenum and gallbladder.
The Chinese medicine and law of rhythm rules say that the meridians work for 24 hours, divided in 12 two hour intervals. Each meridian has its peak when the opposite meridian hits its low.
A Chinese doctor always asks his patient first about what time of the day the symptoms appeared. Knowing that, he understands where the problem originates, or rather where the energy circulates with issues, or there is too much energy.
Its best to follow the biological clock and write down the time when the symptoms appeared. Also, note the time of day when you’re most energetic, and when you wake up at night – that also implies there’s an issue in a certain part of the body.
1 – 3 AM – liver (detoxification, muscles and eyes)
3 AM – 5 AM – lungs (skin)
5 AM – 7 AM – colon (assimilation, elimination, skin)
7 AM – 9 AM- stomach (lymph, food digestion)
9 AM – 11 AM – spleen, pancreas (lymph, food digestion)
11 AM – 1 PM – heart (artery blood circulation)
1 PM – 3 PM – small intestine (digestion, assimilation, arteries)
5 PM – 7 PM – kidneys (bones, teeth, ears, filtration, elimination)
7 PM – 9 PM – cardiac layer (constriction of blood vessels)
9 PM – 11 PM – duodenum (thermoregulation)
11 PM – 1 AM – gallbladder (digestion, muscles, eyes)
Time of minimal functions or rest
1 AM – 3 AM – small intestine (digestion, assimilation of the arteries)
3 AM -5 AM – bladder (bones, teeth, cleaning elimination)
5 AM – 7 AM – kidney disease (bones, teeth, ears, filtration, elimination)
7 AM – 9 AM – the heart layer (constriction of blood vessels)
9 AM – 11 AM – duodenum (thermoregulation)
11 AM – 1 PM – gallbladder (digestion, muscles, eyes)
1 PM – 3 PM – liver (detoxification, muscles and eyes)
3 PM – 5 PM – lungs (skin)
5 PM – 7 PM – colon (assimilation, elimination, skin)
7 PM – 9 PM – stomach (lymph, food and digestion)
9 PM – 11 PM – spleen, pancreas (lymph, food digestion)
11 PM – 1 AM – heart (artery blood circulation)
One meridian (organ) has its highest energy level exactly when another on the opposite side has its lowest.
Take the liver for example: its highest energy levels are between 1 and 3 AM, and at that time the small intestine is at its lowest energy level. When you eat late and go to sleep, the food is not absorbed well in the small intestine, so you have to avoid certain activities when the energy of the body involved in the activity is at its lowest.
During the maximum activity all the functions are boosted. In cases of diseases of excess energy which burden a system, they will show symptoms and that is the exact time to reduce the excess energy.
