The flowers of several jasmine species are the
source of the aromatic jasmine oil (oleum
jasmini), which contains eugenol and plays an
important role in the perfume industry (cf.
essential oils). Moreover, two African species have
been reported to have psychoactive effects. In
Abyssinia, the leaves of Jasminum floribundum R.
Br. (known as hab el tsalim) are used as an
"inebriating agent"; the leaves of Jasminum
abyssinicum R. Br. are used in Eritrea for the same
purpose (Hartwich 1911, 811 *). The constituents
are unknown. Gelsemium sempervirens is also
known as yellow jasmine.
