Do NOT use alone for inflammatory knee disorders such as rheumatoid arthritis, bursitis, synovitis, or tenosynovitis — use Flex (Heat), Flex (CD), or others based on TCM diagnosis. Contains Dan Shen (Radix et Rhizoma Salviae Miltiorrhizae) and Dang Gui (Radix Angelicae Sinensis) — patients on anticoagulant or antiplatelet therapies such as Coumadin (warfarin) should use with caution or not at all. Optimal results occur when herbs are combined with acupuncture, electro-stimulation, and tui-na. Patients with arthritis should avoid vigorous exercise — mild exercise such as tai chi chuan and walking are recommended.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eClinical distinction — Knee \u0026amp; Ankle (CR) vs. Knee \u0026amp; Ankle (AC):\u003c\/b\u003e Knee \u0026amp; Ankle (AC) is for the acute phase — swelling, inflammation, and pain from recent injury or trauma. Knee \u0026amp; Ankle (CR) is for the chronic and rehabilitation phase — repetitive wear and tear, atrophy, degeneration, decreased mobility, and ligament instability. Use Knee \u0026amp; Ankle (AC) first for acute injuries; transition to Knee \u0026amp; Ankle (CR) + Flex (MLT) for chronic recovery and rehabilitation. Note: untreated acute sprains and strains lead to ligament and joint instability and more frequent re-injury — Knee \u0026amp; Ankle (CR) ensures repair of minor ligament tears and facilitates complete recovery to prevent future re-injury.\u003c\/p\u003e\n\n\u003ch2\u003eCLINICAL APPLICATIONS\u003c\/h2\u003e\n\u003cp\u003e* \u003cb\u003eChronic knee and ankle disorders\u003c\/b\u003e with atrophy and degeneration of soft tissues (muscles, tendons, and ligaments)\u003c\/p\u003e\n\u003cp\u003e* \u003cb\u003eChronic leg disorders\u003c\/b\u003e with weakness, stiffness, decreased range of motion, and decreased mobility of the joints\u003c\/p\u003e\n\u003cp\u003e* Sprain, partial rupture, stretch, or tear of ankle ligaments leading to instability and frequent re-injuries\u003c\/p\u003e\n\u003cp\u003e* Rehabilitation and recovery phase following acute knee and ankle injuries\u003c\/p\u003e\n\u003cp\u003e* Muscle wasting and atrophy from lack of exercise and physical movement in late-stage musculoskeletal injuries\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eBackground:\u003c\/b\u003e Musculoskeletal and connective tissue injuries lead to over 10 million clinic visits per year in the United States. Chronic injuries are characterized by dull pain, stiffness, numbness, and decreased muscle mass and strength. Treatment of chronic injuries includes relief of pain and restoration of physical and physiological functions. Degeneration of soft tissues (muscles, tendons, and ligaments) is often seen in chronic knee and ankle disorders, leading to decreased range of motion and mobility. Many patients experience pain or worsening of their condition prior to rainy days — antirheumatic herbs that dispel wind-damp are essential in these cases.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eKey herb-level clinical data:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e— \u003cb\u003eChuan Niu Xi\u003c\/b\u003e (Radix Cyathulae \/ Cyathula Root): chondroprotective — potently inhibits MMP-13, an important enzyme for degradation of the cartilage collagen matrix especially under arthritic conditions;
