Deficiency of both qi and blood is what Chinese medicine calls qi deficiency and blood deficiency. Deficiency of qi and blood will lead to the decline of viscera function and lead to premature aging.

1. the concept of qi: qi is a fine substance running in the human body. It has strong energy activity, which stimulates and promotes the functional activities of body organs, so it also represents the qi of five internal organs and the qi of meridians. The function of qi is mainly to warm the body, resist the invasion of external evils, and participate in the metabolism of visceral functions.

Qi deficiency: that is, the function of zang-fu organs decreases and the disease resistance is poor. Qi deficiency leads to chills, spontaneous sweating, dizziness, tinnitus, listlessness, fatigue, palpitation, shortness of breath and dysplasia.

2. The concept of blood: blood is a red liquid flowing in meridians. The function of blood has two aspects. First, regulate viscera, body, meridians and bones. Full of qi and blood, healthy body, rosy complexion, smooth skin, moist hair and flexible joints. Second, blood is the material basis of spiritual activities. Full of blood and refreshing, quick thinking. Deficiency of qi and blood leads to trance and palpitation.

Blood deficiency: sallow complexion, dry skin, dry hair, cracked nails, blurred vision, numbness of hands and feet, insomnia, dreaminess, forgetfulness and palpitation.

3. the source of qi and blood

There are two sources of qi and blood. First, it is endowed with innate nature. That is, the innate nature of parents (the nature of reproduction). Secondly, the nature of the day after tomorrow is the nature of Shui Gu and nature, which are transported only through the spleen and stomach. Qi can promote blood circulation, learning can carry qi, and qi and blood are born together. Qi deficiency means less blood, and less blood means qi deficiency, so TCM is generally deficient in both qi and blood in clinic.
