Natural home remedies for removing fluid from knee joints include the RICE protocol (rest, ice, compression and elevation) for reducing swelling. Other treatments include herbal supplements and alternative forms of physical therapy, as stated by Healthline.
Fluid builds in the knee as a result of several different factors. Injuries such as fractures, ligament or meniscus tears, and overuse trauma all draw fluid to the knee. Such conditions and diseases as osteoarthritis, rheumatoid arthritis, gout, infection, bursitis, bleeding disorders, tumors and cysts all lead to fluid gathering around and inside the knee joint, according to Mayo Clinic.
When carrying out the RICE protocol, sitting on a couch, elevating the feet on a cushion, and applying a bag of ice or frozen small vegetables to the knee reduces swelling. Using a compression bandage while going about normal daily activities applies pressure to fluid, sending it out of the joint. Some natural supplements that help reduce knee swelling include ginger extract, willow bark, glucosamine and chondroitin sulfate. Ginger extract and willow bark reduce pain and inflammation, and chondroitin sulfate and glucosamine address more severe cases of pain and swelling. Tai chi is an alternative form of physical therapy that boosts flexibility and balance. It also increases range of motion, fighting the tendency to remain sedentary that accompanies pain and allows fluid to build as well, notes Healthline.
