Sinews

jīnTissues & Senses

Overview

Sinews (Jin) refer to fascia, tendons, and ligaments that attach to bones and converge at joints, governing joint movement and constituting one of the Five Body Constituents. In Traditional Chinese Medicine, they are closely linked to the Liver, which nourishes them through Blood, and their health reflects Liver Blood sufficiency and the absence of internal Wind.

Theoretical points

  • Sinews are tissues such as fascia, tendons, and ligaments that attach to bones and gather at joints, responsible for joint movement and stability.
  • The Liver governs the sinews, as Liver Blood nourishes all sinew tissues throughout the body.
  • When Liver Blood is sufficient, sinews are strong, movement is agile, and the body resists fatigue.
  • Liver Blood deficiency leads to malnourishment of sinews, manifesting as numbness, limited flexion and extension, tremors, and easy fatigue.
  • Internal Liver Wind can cause spasms, convulsions, and opisthotonos, reflecting hyperactive sinew contraction.

Common patterns

  • Liver Blood deficiency fails to nourish the sinews, resulting in symptoms like limb numbness, stiffness, tremors, and fatigue.
  • Liver Wind stirring internally (e.g., from heat or Yin deficiency) triggers sinew spasms, cramps, and severe rigidity.
  • Chronic overuse or trauma may impair sinew function, often involving Blood stasis or Qi stagnation in the affected joints.

Daily care

  • Maintain regular, moderate exercise to promote smooth Qi and Blood flow, supporting sinew health.
  • Ensure adequate rest and avoid overexertion to prevent depletion of Liver Blood and sinew fatigue.
  • Adopt a balanced diet with nourishing foods (e.g., dark leafy greens, legumes) to support Blood production.
