In TCVM, the Liver governs the sinews, including tendons, ligaments, and fibrous connective tissue; when Liver Yin or Liver Blood become deficient, the sinews lose their moisture and nourishment and become brittle and inelastic, predisposing them to stiffness, microinjury, and fiber tearing under the concussive and tensile forces of athletic work. Sound Tendon's eleven-herb formula nourishes Liver Blood and Yin, tonifies Kidney Yang to strengthen the structural foundation of the sinews, and activates Blood circulation to ensure the nourishment reaches the tendons and ligaments. This formula is appropriate for sport horses and performance horses recovering from tendon or ligament strain, horses with chronically tight or stiff tendons, and horses whose sinew health has been compromised by demanding training schedules. Available in traditional powder (500g, 900g, 1200g) and Flax Plus (30-day and 60-day supply); a six-tablespoon scoop is included with the Flax Plus format. Dosing varies by body weight and health condition; your authorizing veterinarian will provide specific guidance.

The Liver is analogous to a healthy green tree, strong enough to support structure yet flexible enough to bend without breaking. Tendons and ligaments must have the same dual quality: the strength to support the body and the flexibility to absorb the concussive and tensile forces of movement. When Liver Yin or Liver Blood become deficient, the sinews lose their nourishment and become like a dried-out tree: brittle, inelastic, and prone to stiffness and fiber tearing under the demands of training. Sound Tendon nourishes Liver Blood and Yin to restore the moisture and resilience the sinews need, and adds Kidney-tonifying herbs because the Kidney governs the bones and provides the deep structural foundation that supports Liver function and sinew health. Activating Blood herbs ensure the nourishment is actively circulated to the sinew tissue.

In TCVM, the Liver governs the sinews, including tendons, ligaments, and fibrous connective tissue; when Liver Yin or Liver Blood become deficient, the sinews lose their moisture and nourishment and become brittle and inelastic, predisposing them to stiffness, microinjury, and fiber tearing under the concussive and tensile forces of athletic work. Sound Tendon's eleven-herb formula nourishes Liver Blood and Yin, tonifies Kidney Yang to strengthen the structural foundation of the sinews, and activates Blood circulation to ensure the nourishment reaches the tendons and ligaments. This formula is appropriate for sport horses and performance horses recovering from tendon or ligament strain, horses with chronically tight or stiff tendons, and horses whose sinew health has been compromised by demanding training schedules. Available in traditional powder (500g, 900g, 1200g) and Flax Plus (30-day and 60-day supply); a six-tablespoon scoop is included with the Flax Plus format. Dosing varies by body weight and health condition; your authorizing veterinarian will provide specific guidance.

When Liver Yin or Liver Blood become deficient, the sinews lose their nourishment and become like a dried-out tree: brittle, inelastic, and prone to stiffness and fiber tearing under the demands of training. Sound Tendon nourishes Liver Blood and Yin to restore the moisture and resilience the sinews need, and adds Kidney-tonifying herbs because the Kidney governs the bones and provides the deep structural foundation that supports Liver function and sinew health.

The Liver governs the sinews; when Liver Blood or Yin is insufficient, the sinews lose their nourishment and become like a dried-out tree, lacking the flexibility needed to withstand the concussive and tensile forces of movement and training. Horses that benefit most include performance horses and sport horses with a history of tendon or ligament strain, horses with chronically tight or stiff tendons, and horses whose sinew integrity has been compromised by demanding training schedules. A TCVM-trained veterinarian can confirm that Liver Blood-Yin deficiency is the appropriate pattern before authorization.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow is Sound Tendon administered, and what are the recommended doses for a 1,000 lb horse?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eFor the traditional powder, administer two tablespoons twice daily for the first 20 days, then two tablespoons once daily. For the Flax Plus format, administer one scoop (six-tablespoon scoop included) twice daily for the first 20 days, then one scoop daily. Mix into grain for easy administration. If the horse is reluctant to eat herbs, begin with small amounts in grain and gradually increase, or choose the Flax Plus version. Confirm dosing for horses of other weights with your authorizing veterinarian. Not for use in pregnant mares.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eWhy does Sound Tendon include Kidney Yang-tonifying herbs alongside Liver Yin and Blood nourishing herbs?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eIn TCVM, the Liver and Kidney share a deep constitutional relationship: the Kidney stores Essence and governs the bones, while the Liver stores Blood and governs the sinews. Kidney Yang and Essence are the deep energetic foundation that supports Liver function; when the Kidney is strong, the Liver receives the constitutional support it needs to adequately nourish the sinews. Yin Yang Huo, Bu Gu Zhi, and Shan Zhu Yu tonify Kidney Yang and Essence to strengthen this foundation, ensuring the Liver Blood and Yin nourished by the formula has the constitutional support needed to fully restore sinew health. This dual Liver-Kidney approach is characteristic of classical TCVM sinew rehabilitation formulas.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eHow long does it take to see improvement in tendon and ligament condition, and can this formula be used alongside conventional rehabilitation?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003eBecause Sound Tendon addresses an underlying Liver Blood and Yin deficiency, improvement in sinew resilience and flexibility typically requires consistent use over 4 to 8 weeks, with full constitutional strengthening of the tendons and ligaments potentially taking 2 to 3 months of continuous use. It can generally be used alongside conventional tendon and ligament rehabilitation protocols, including controlled exercise, controlled hand-walking, and physiotherapy, under the guidance of both a TCVM-trained veterinarian and your primary veterinarian. Your authorizing veterinarian will guide the appropriate course length, dosing schedule, and integration with any concurrent rehabilitation plan based on your horse's condition and response.\u003c\/span\u003e\u003c\/p\u003e"}
