*symbol of hope*

Butterfly - Traditionally the butterfly represents freedom, transformation and recovery. Also, one of the more common symptoms of Lupus is called a butterfly rash. It is a red rash across the nose and cheeks that resembles a butterfly. That is why the butterfly has become the symbol of hope for Lupus patients.
