Natural Herbs That Treats Arthritis Pain: The pain of arthritis is very painful. This pain usually occurs in the elderly due to increase in swelling in the joints. Arthritis occurs when the cartilage between the bones under the joints wears down. Gout disease occurs when uric acid starts increasing in the body. Uric acid is made from purine, a by-product of protein synthesis. When purine breaks down, it becomes uric acid. Normally, excess uric acid is filtered in the kidney and comes out of the body through urine. But when uric acid starts increasing or food that increases uric acid is consumed more, then uric acid is not filtered completely by the kidney, due to which it starts increasing. However, if the diet is controlled, then the pain in arthritis can be easily relieved. There are some amazing herbs too, with the help of which arthritis pain is relieved.
