Lupus is an inflammatory disease caused when the immune system attacks its own tissues. This attack leads to inflammation and chronic pain in the skin, joints and muscles. Lupus can also cause sun sensitivity, weight loss, hair loss and digestive problems. In 50 percent of cases, lupus causes a rash on the face known as a butterfly rash, which can get worse with sunlight and also appear on other parts of the body. Research indicates that at least 1.5 million Americans have lupus. Potential causes include allergic reactions, viruses, emotional stress, estrogen disruption due to pregnancy or birth control, hormonal imbalances, poor digestion and metal toxicity. Natural remedies for lupus—including an anti- inflammatory diet, exercise and essential oils for pain and stress reduction—can help manage symptoms and prevent further complications.
