This is the purest clove bud oil we can find. We always use the best sources but they change from time to time as we find more. SAFETY WARNING: For external use only. Other than aromatherapy, dilute with a carrier oil. For topical use, rub a very small amount on the inside of your elbow area to test for any allergic reaction before use. Keep out of the reach of pets. Essential oils can be potentially toxic to pets at certain concentrations. Cats can be especially sensitive to essential oils. Avoid contact with eyes, keep out of the reach of children. If pregnant, consult with your health care provider before use. Clove oil blends well with citronella, grapefruit, lemon, orange, peppermint, rosemary, and rose oils
