Botanical History

On the question of the origin of cowpea, Purseglove (1968) suggested that it may have been tropical Africa, where wild species can be found. He also believed that cowpea was introduced to Asia and the Mediterranean region through Egypt and other Arab countries in the early days and is now native to the tropics, while the main areas of origin are tropical Africa and tropical Asia, with our species accounting for only about 1/10th of the species in the genus.

But according to the literature, "Guangyun" book that has the word "cowpeas", this book was originally written in 601 years has been anonymous, has been reworked, now exists in the Song dynasty Lu Pangnian, such as the revision of the book.

The Northern Song Dynasty's "Tu Jing Ben Cao" has a record of cowpeas; Su Shi has a poem about cowpeas. In the Ming Dynasty, since Zhu Sao's "Salvation of the Deserted Ben Cao", "Bin Min Tu Jie", "Ben Cao Gang Mou" and other books and journals have a record of cowpeas, so it can be seen that the cowpeas have been widely cultivated in the Ming Dynasty. In the historical records, the climate of the Yellow River basin was once warmer, and according to the records of the ancient books, it is possible that China is also one of the places of origin of cowpea.
