It is widely cultivated for its attractive and sweetly fragrant flowers. The flowers are also used for perfumes and for making tea. It is known as the Arabian jasmine in English. It is the national flower of the Philippines, where it is known as sampaguita. It is also one of the three national flowers of Indonesia, where it is known as melati putih.

Jasminum sambac is classified under the genus Jasminum under the tribe Jasmineae. It belongs to the olive family Oleaceae.

Despite the English common name of "Arabian jasmine", Jasminum sambac is not originally native to Arabia. The habits of Jasminum sambac support a native habitat of humid tropical climates and not the arid climates of the Middle East. Early Chinese records of the plant points to the origin of Jasminum sambac as eastern South Asia and Southeast Asia. Jasminum sambac (and nine other species of the genus) were spread into Arabia and Persia by man, where they were cultivated in gardens. From there, they were introduced to Europe where they were grown as ornamentals and were known under the common name "sambac" in the 18th century. A name which is derived from a misapplication of the Sanskrit name champaka, which refers to the fragrant flowered shrub Michelia champaca.
