Syzygium aromaticum is the name for a small evergreen tree of the myrtle family and for its unopened flower bud, an important spice. The buds are reddish-brown in color and have a strong, aromatic flavor and aroma. The cloves are gathered by hand, dried, and marketed either whole or ground for culinary purposes. Syzygium aromaticum may have aphrodisiac properties. Clove oil is widely used in synthetic vanilla and other flavorings as well as in  perfume. Syzygium aromaticum oil is often considered medicinal and antiseptic.

The flower bud of Syzygium aromaticum has been used in Unani medicine since ancient times as an aphrodisiac for the treatment of male sexual disorders. The present study is aimed to investigate the effect of 50% ethanolic extract of clove on general mating behaviour, libido, potency along with its likely gastric ulceration and adverse effects on sexually normal male albino rats. The suspension of the extract was administered orally at the dose of 100, 250, and 500 mg / kg, to different groups of male rats once a day for seven days. The female albino rats involved in mating were made receptive by hormonal treatment. The general mating behavior, libido and potency were determined and compared with the standard reference drug sildenafil citrate. The probable gastric ulceration and adverse effects of the extract were also evaluated. Oral administration of the extract significantly increased the Mounting Frequency, Intromission Frequency; Intromission Latency, Erections; Quick Flips, Long Flips as well as aggregate of penile reflexes and caused significant reduction in the Mounting Latency and Post Ejaculatory Interval. The most appreciable effect of the extract was observed at the dose of 500 mg/kg. The test drug was also found to be devoid of any conspicuous gastric ulceration and adverse effects. The results indicated that the 50% ethanolic extract of Syzygium aromaticum produced a significant and sustained increase in the sexual activity of normal male rats, without any conspicuous gastric ulceration and adverse effects. Thus, the resultant aphrodisiac effectivity of the extract lends support to the claims for its traditional usage in sexual disorders.
