According to Chinese Medicine theory, restless legs syndrome (RLS) is resulted from both internal weakness, and excess pathogenic disturbances. The internal weakness includes dysfunction of the liver and kidney, and insufficiency of blood and qi (vital energy); the excess pathogens can be wind, coldness, dampness, and blood stasis etc. Middle-aged or elderly individuals are more likely to be due to internal weakness, while young individuals are likely to be due to excess pathogenic disturbances.
