Chinese Theory

The liver controls the sinews such as tendons, ligaments, and fibrous tissue. The liver is analagous to a healthy green tree with strength and yet pliablility to withstand the forces of the environment. The tree needs to have strength to support and yet have flexibility to bend with the wind. Sinews, tendons and ligaments, are similar. They need to have strength to support the body but have flexibility to bend and support the concussive forces placed upon them.

When liver yin or liver blood become deficient the sinews become brittle like a dried out tree. The brittleness to the structures doesn’t allow for the flexibility needed in motion and can lend towards tearing of fibers. The herbs in Sound Tendon tonify liver yin and liver blood to restore strength and resilience.

Treatment Principles: Tonifies liver yin, nourishes liver blood, and strengthen sinews
