The article puts forward a new point about "the theoretical study of biological origins of Chinese herbs". The origin, meaning and reason for emergence of "regional habitually used drugs" are discussed and examples of these drugs used in history and modern times are given. It is indicated that these drugs are gradually differentiated with their species character being made clear. It is thus suggested that more efforts be made to study these drugs, promote their differentiation and treat them by their character and nature.
