clove dehydrated

Long-used in traditional medicine, there is evidence that clove oil containing eugenol is effective for toothache pain and other types of pain,^[8][9] and one review reported efficacy of eugenol combined with zinc oxide as an analgesic for alveolar osteitis.^[10] Studies to determine its effectiveness for fever reduction, as a mosquito repellent, and to prevent premature ejaculation have been inconclusive.^[8][9] It remains unproven whether blood sugar levels are reduced by cloves or clove oil.^[9] Use of clove for any medicinal purpose has not been approved by the US Food and Drug Administration, and its use may cause adverse effects if taken orally by people with liver disease, blood clotting and immune system disorders, or food allergies.
