Question
The child’s nail growth is not good, and it has been ongoing for a while. Parents are concerned and hope to receive professional medical advice.
Answer
According to traditional Chinese medicine theory, nail growth requires nourishment from Qi, blood, and body fluid, and the transportation of these nutrients depends on the meridians. The meridians primarily involve the three Yin and three Yang meridians of the hands and feet. The hand Yang meridians run from the hands to the head, while the foot Yang meridians run from the head to the feet. Based on your description, slow finger nail growth and faster toe nail growth may be symptoms of Yang Deficiency Syndrome. Yang Qi represents the functions of the internal organs and vitality of the body. When Yang Qi is weak, it is more difficult to push upwards but relatively easier downwards, like water flowing more easily downward when water pressure is low. Therefore, the finger nails may receive less nourishment in terms of essence and blood compared to the toe nails.
