Eugenia caryophyllata is indigenous to the Maluku islands of Indonesia

Known Uses

Clove essential oil (CEO) is commonly used as an antiseptic for oral infections and to kill a wide variety of microbes. University of Buenos Aires, Argentina researchers found that clove has the greatest effect over E. coli, Staph aureus and Pseudomonas aeruginosa, bacterias that can lead to pneumonia and skin infections.

CEO is considerably high in manganese (126.4%) – which is used to prevent and treat osteoporosis, anemia and premenstrual syndrome (PMS); CEO contains a substance (eugenol) that is a powerful anti-inflammatory. Low doses of eugenol have been shown to protect the liver against ischemia/reperfusion injury (a known cause of liver disease). Eugenol reverses inflammation, and slows apoptosis (cell death). As an anti-bacterial and anti-fungal it is used in dental care to slow tooth erosion and for relieving the pain and discomfort associated with various dental disorders.

Clove Essential Oil has the highest ORAC (Oxygen Radical Absorbance Capacity) value of any substance - 1,078,700 units (almost 3X higher than Myrrh). ORAC is a measurement of the antioxidant value in foods, molecules that reverse the damage that free radicals cause including cell death and cancer.


The Chinese have used clove for more than 2,000 years as a fragrance and spice. Since spreading to the international community, it has been added to numerous products for agricultural, cosmetic and industrial purposes. The greatest asset of CEO, however, is related to its widespread application in homeopathic medicine. Because it contains such an elevated level of eugenol, clove essential oil (CEO) has proven to be extremely versatile and has been thoroughly researched as an effective alternative to many current medical treatments.


Clove oil contains a chemical called eugenol that seems to slow blood clotting. There is a concern that taking clove oil might cause bleeding in people with bleeding disorders. There is also a concern that it might cause bleeding during or after surgery. Stop using clove at least 2 weeks before a scheduled surgery.

Frequent and repeated application of clove oil in the mouth or on the gums can sometimes cause damage to the gums, tooth pulp, skin, and mucous membranes.

In children, clove essential oil is likely unsafe to take by mouth. It can cause severe side effects such as seizures, liver damage, and fluid imbalances.

There is not enough reliable information about the safety of taking clove in medicinal doses if you are pregnant or breast-feeding. Stay on the safe side and avoid use.
