Topical: Dilute with a carrier oil, unscented lotion or unscented cream and apply on area of concern or as desired. Consider using a roll-on applicator for ease of application of prediluted oil. According to Tisserand, Allspice "was neither irritant nor sensitizing when patch tested on a panel of 32 volunteers at 8%" dilution (48 drops to an ounce). He recommends a "dermal maximum of 0.15% for both leave on and rinse off products in order to avoid skin sensitization." Inhalation: Diffuse or use a personal Nasal Inhaler Internal: In Essential Oil Safety, Robert Tisserand (2013 edition, p. 393) writes regarding oral use of Pimento Berry/Allspice: "Should not be taken in oral doses."
Potentially carcinogenic based on methyleugenol content. Methyleugenol is a rodent carcinogen when exposure is sufficiently high.
Avoid contact with the eyes and other sensitive areas. Essential oils are both lipophilic and hydrophobic. Lipophilic means they are attracted to fat— like the membranes of your eyes and skin. They are also hydrophobic, meaning they do not like water. Applying a carrier oil will create another fat for the essential oil to be attracted to other than the membranes of the eyes or skin. Tisserand suggests: "With essential oils, fatty oil has been suggested as an appropriate first aid treatment, though the advantage of saline [eyewash] is that the eyes can be continually flushed, and this is less easy with fatty oil.” We are not aware of a case where essential oil in the eyes caused permanent injury or long-term discomfort, but if you feel concerned, please call your health care provider.
