Clinical manifestations: coughing up blood, spitting out blood, urinating blood, red tongue, stringy pulse.
Blood heat is the invasion of heat and poison into the blood, running into the blood, often occurs in the tropics, or work in a very hot environment, or in the hot season, overexposure to the sun, or sweating too much, did not replenish the water, a long time thirsty, loss of water, or to eat fried, fried, and other hot and dry food, or take some stimulants, may lead to blood heat.
The symptom of blood heat is that the blood is hot and goes everywhere. Everyone has experienced blood heat at one time or another, they just don't quite remember it. In the summer, after you've been out in the sun, your blood is running around in your body, making it hard for you to sit still. You usually say, "It's hot. If you feel it carefully, you can realize that your skin has a little prickly sensation from the inside out, and that's the hot blood moving around. In some people, the microvessels are more fragile, and there are little red dots under the skin. That is when the Spleen meridian does not regulate the blood vessels well, and when the hot blood runs to the end, the blood vessels can't hold back the blood, so that the blood seeps out a little bit. What it looks like is a blotchy skin.
In the case of hot blood, even the blood coming out of the veins is bright red. It is not like the usual vein blood which is darker red. In the early days, there was a doctor in the West who accompanied a laborer on a ship across the equator to work in South Africa. In those days, there was no air-conditioning in the cabins of the ships, and many workers fell sick while crossing the equator. The treatment at that time was to cut open a vein and bleed the blood, so that the blood could flow out a little bit, and the symptoms improved a lot. That was caused by blood heat. At that time, as soon as he cut the vein open, he was shocked to see that the blood was bright red and thought he had cut an artery. Later, he thought of a theorem in physics about thermodynamics from this, that is, the conversion of energy, heat energy will be converted into the body's internal energy. Thus getting a cognizance in physics.
And restlessness. This time must be very irritable, fidgety, at one time up to walk, at one time and then sit down. The tongue is very red. If it is a little more serious, there will be delirium, that is, speaking without thinking, talking nonsense. A little more serious, it will be coma, unconscious.
As I said earlier, the body's operations are all non-linear, and when the blood is hot, the non-linear phenomena are very powerful. When it becomes so powerful to a certain extent, the body will go out of control, and the organs will lose their proper rhythm and coordination with each other, and it will be easy to fall unconscious.
The number of pulses is the rapid beating of the blood veins. This is because in order to accelerate heat dissipation, circulation must be accelerated. Heat is dissipated through the epidermis and also through the breath.
There are about three kinds of blood diseases mentioned above. The first is blood deficiency, in which blood production is insufficient and the function of nourishing and moistening the body is not good. The second type is blood stasis, caused by poor channeling. The third is blood heat, the temperature of the environment is too high, so that heat and poison invade the blood.
