Psoriatic arthritis (PA) is a form of arthritis that affects some people that have the skin condition psoriasis – a condition resulting in red patches of skin topped with silvery scales. Joint pain, stiffness and swelling are the main symptoms of PA, and are caused by a hyperactive immune system that creates inflammation in the body. There is currently no cure for PA, so treatments focus on controlling symptoms and preventing damage to joints. Without treatments, PA may become disabling. Several medications can be used to decrease pain and inflammation, or there are procedures to reduce inflammation, such as steroid injections or joint replacement surgeries. However, before utilizing these measures, many people turn to natural remedies first. There are several spices that have been shown beneficial in psoriatic arthritis.
