Discussion on ‘caducity induced by deficiency and stasis' and ‘tumor induced by deficiency and stasis' under the theory of qi and blood

Caducity includes physiological and pathological caducity, it is the main factor of age-related disease, which often associates with tumor. Qi and blood are the essential elements to constitute and maintain human activities, and they are the material basis of Zang and Fu, meridians and collaterals. Between qi and blood, qi is the commander of blood, blood is the mother of qi. Qi and blood deficiency can not nourish the body organs and tissues, leading to decline of systemic organ function. The less of qi and blood can lead blood stasis which will cause new blood no living, aggravating the deficiency. So the formation of ‘caducity induced by deficiency and stasis'. Yuan qi deficiency is the cause of human aging. Qi deficiency and blood stagnation can easily lead to the formation of blood stasis. That is because of deficiency and blood stasis. The long term of blood stasis can cause blood dry, and it may stay or backup somewhere. The blood stay may cause the formation of abdominal mass swollen, which is the reason of ‘tumor induced by deficiency and stasis'. From the manifestation of senescence and tumor formation and clinical study, it is thought that the deficiency of qi and blood and circulation delay leads to senescence acceleration and tumors.
