[Safflower's origin and changes of producing areas].

ABSTRACT

Human's application of safflower (Carthamus tinctorius) has a long history, but the origin remains unclear. Safflower was introduced into China for traditional Chinese medicine, and Sichuan was major producing area. However, in recent years, the main producing area is in Xinjiang province, in contrast Sichuan safflower is difficult to find. By reading relevant document literature and the production and marketing information of safflower, and having field investigation in the main producing areas, the origin of safflower and the reasons of producing areas' changes were explored. The origin of safflower is considered as the Fertile Crescent in reasonably. The change of producing areas in China is effected by the factors of natural environment and society. The suitability of producing areas and quality of safflower still need to study further.
