Fights bacterial, viral and fungal infections. Great for toothaches! You can bite down slightly on a whole clove (being careful of course to avoid further tooth injury as in the case of a cracked tooth) and then hold the clove in between the cheek and area of toothache. As well, you can dilute clove oil (pure clove oil would irritate tissue!) with olive oil and apply to the gum area with a Q-tip. Avoid swallowing. Clove also improves digestion.
There are no contraindications. Clove can and should be used often in the kitchen!
