Saffron and saffron are the same. They are different names of the same medicinal material. Among them, saffron is a scientific name, which is mainly used in academic journals, scientific research papers and other formal occasions. Crocus sativus is a common name, which is often used in daily life. Crocus sativus has other names.

Crocus sativus is a plant of Crocus belonging to Iridaceae, which originated in ancient Persia, namely Iran and other countries and regions. Because Persia is located in the west of China and its flowers are red, it is called "crocus", which means red flowers from the west. Later, saffron entered Tibet through India and was transported to the mainland through Tibet. So it is commonly known as "saffron", which literally means saffron. Many people also mistakenly believe that the origin of saffron is Tibet.

Many things have two or more names, which are very common in imported goods, mainly due to cultural differences in the place of origin and different ways of transmission. Crocus sativus was also called Bobran and Crocus sativus in ancient times. After a long historical change, it gradually unified into crocus and crocus.
