Clove oil is obtained by extraction from the dried flower buds of the clove plant. Traditionally, it has been used as a flavouring spice in foods, or as a fragrance. It is also found in topical analgesics. Clove oil has shown to exert some antimicrobial activities. The antioxidant and antimicrobial activity of clove is higher than that of many fruits, vegetables, and other spices . Clove is native of Indonesia but is now cultured in several parts of the world, including Brazil in the state of Bahia. This plant represents one of the richest source of phenolic compounds such as eugenol, eugenol acetate and gallic acid and has great potential for pharmaceutical, cosmetic, food and agricultural applications . Interestingly, clove oil has been studied for its potential benefit in treating neuropathic pain, as well as vaginal candidiasis with promising results , . The FDA categorizes clove oil as generally recognized as safe (GRAS) for use in dental cement or as a food additive .

The chief constituent present in clove oil is the phenol "eugenol" which is present in amounts up to 85%. Clove oil acts as a germicide to Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa . Clove oil is thought to inhibit prostaglandin synthesis, thereby reducing painful symptoms . Eugenol, the main constituent of clove oil is purported to have anticancer action. In one study, eugenol-treated HL-60 cells showed features of apoptosis including DNA fragmentation and formation of DNA ladders in agarose gel electrophoresis. It was observed that eugenol transduced the apoptotic signal via reactive oxygen species (ROS) generation, inducing mitochondrial permeability transition (MPT), decreasing anti-apoptotic protein bcl-2 level, inducing cytochrome c release to the cytosol, and subsequent apoptotic cell death. When taken together, the study showed that ROS plays a critical role in eugenol-induced apoptosis in HL-60, and this is the first report on the mechanism of the anticancer effect of eugenol .
Clove oil is primarily indicated in conditions like colic, flatulence, and toothache .
