@SarahGen-- I've been looking into possible natural treatments for lupus for quite a while now. Based on my experiences and discussions I've had with others, the results appear to be mixed. Natural remedies work for some but not for others and some remedies and methods are better. Unfortunately, there is no cure for lupus and the most that natural remedies, or any treatment for that matter, can do is reduce symptoms. Don't expect any miraculous results from any type of treatment.
I've personally gotten good results with natural anti-inflammatory supplements and things like yoga, meditation and prayer to relieve stress. Fish oil and vitamin E supplements are beneficial because they have natural anti-inflammatory properties. There are also amino acids that you can take to relieve joint stiffness and pain if you are experiencing them. For fatigue, you can take natural herbs like ginseng for extra energy.
Stress is also a major trigger for lupus flares so it's important to fight stress by regularly practicing meditation or praying, and spending time in nature and with pets.
None of these cure lupus but they certainly help to some extent. Always check with your doctor before starting any supplements or herbs.
