Treat arthritis of the knee at home by exercising, using hot and cold therapy and modifying the diet to include the right fatty acids and the spice turmeric, according to Healthline. Herbal supplements and low-impact exercises, such as swimming, can be beneficial for arthritis of the knee.
Alternating hot and cold packs to the knee may also be of benefit. Dietary alterations to include omega-3 fatty acids into the diet can sooth arthritis woes, and the spice turmeric has anti-inflammatory properties that can reduce the swelling caused by the condition, reports Healthline.
Some herbal supplements are purported to help with arthritis, reports Healthline, including ginkgo, thunder god vine, stinging nettle, bromelain and boswellia. However, be sure to talk to a doctor before adding these supplements, since they interact with medications.
