The Brain

nǎoZang-Fu

Overview

The Brain (Nao) is a curious hollow organ located in the skull, formed by the convergence of marrow and known as the Sea of Marrow. It governs spirit, consciousness, thought, sensation, and movement, and is closely linked to the heart and the five viscera, especially the kidneys.

Theoretical points

  • The Brain resides in the cranium and is formed by the gathering of marrow, hence it is called the Sea of Marrow and belongs to the extraordinary fu-organs.
  • The Brain governs spirit, consciousness, thinking, sensation, and movement, and is responsible for vision, hearing, speech, and physical activity; it is regarded as the 'house of bright spirit' and the 'palace of the primordial spirit'.
  • In traditional Chinese medicine, the functions of the Brain are largely attributed to the Heart, which stores the spirit, and are intimately connected with the five viscera, particularly the Kidneys (which store essence and generate marrow to fill the Brain) and the Liver (which governs free flow of Qi).
  • When Kidney essence is sufficient, the Sea of Marrow is full, resulting in keen hearing and vision, and agile thinking; when the Sea of Marrow is insufficient, symptoms such as dizziness, tinnitus, forgetfulness, diminished vision, and fatigue may arise.

Common patterns

  • Insufficiency of Kidney essence leads to depletion of the Sea of Marrow, manifesting as dizziness, tinnitus, poor memory, blurred vision, and lassitude.
  • Disorders of the Heart spirit or Liver Qi stagnation may indirectly affect Brain functions, causing mental or emotional disturbances.
  • External pathogens or internal imbalances may impair the clear orifices, affecting sensory and motor functions governed by the Brain.

Daily care

  • Maintain regular sleep and rest to nourish the spirit and support Brain function.
  • Engage in moderate physical and mental activity to promote the flow of Qi and blood, benefiting the Sea of Marrow.
  • Avoid excessive mental strain and emotional stress to protect the Heart spirit and Liver Qi.
