However, it will be of great benefit if blood is bled at some acupoints of human meridians before blood donation.
Especially in the liver meridian, kidney meridian, stomach meridian or pericardium meridian, there is no need to put a lot of blood. If you are young, it is usually only ten drops and eight drops of blood. The blood released from these positions is purple-black, which is really waste blood. The so-called blood stasis means that blood cannot return to the heart for blood exchange at these positions.
The principle of blood vessels in the human body is the same as that of tap water pipes. Where there is space, water will fill that space. After the waste blood is released, the siltation of the body will be really dredged, and then the original silted position will be washed away by fresh blood, and other blood will be washed away, so as to return to the heart for blood exchange.
Therefore, blood donation after acupoint bloodletting is a very good health care effect, so from the perspective of health care.
If there is no bloodletting, just ordinary blood drawing, it can only be harmless and beneficial.
Like you, I don't believe in science or western medicine now. I teach myself Chinese medicine. The above is the result of my own DIY. I bleed at Taichong point on the instep (the original point of liver meridian) and the foot socket on the back of ankle bone. This position is the Taixi point, the original point of the kidney meridian.
I am a foreign exchange trader and often stay up late. The reason why I haven't died is because I taught myself Chinese medicine and treated myself. If ordinary people were like me, they would have died years earlier.
