Blood qi is strong, i.e., qi and blood are full and functioning well. The functional activities of the human body are all closely related to qi and blood. Insufficient qi and blood will lead to weakened or diseased functions. According to Chinese medicine theory, qi and blood have a relationship of mutual sustenance, interdependence and mutual utilization. Deficiency of qi and malfunctioning of qi will inevitably affect blood; deficiency of blood and malfunctioning of blood will also inevitably affect qi. Qi and blood and body activities are closely related. If qi and blood are strong, all the body’s functions are healthy. If qi and blood are insufficient, it will be manifested as fear of cold and cold limbs (fear of cold, cold limbs), palpitations (rapid heartbeat, often accompanied by panic), shortness of breath, lack of color, fatigue (mental fatigue, physical weakness) and so on. It can be treated with some proprietary Chinese medicines, such as Bazhen Pill and Gui Spleen Pill. If the organism shows symptoms of insufficient qi and blood, it should consult a doctor in time and take medicines under the guidance of a Chinese medicine practitioner to identify the symptoms, do not take medicines on your own, so as to avoid delays in the condition or adverse reactions.
