Which form of kaffir lime leaf provides the most potent burst of essential oils carrying documented benefits?

Answer

The fresh leaf

Although dried leaves retain some nutritional benefits and can be improved by light toasting, the fresh kaffir lime leaf is recognized as providing the most potent and immediate burst of essential oils. These volatile oils are the carriers of many of the documented benefits, including the intense aromatic qualities and the associated antioxidant and antimicrobial properties. For maximum impact in terms of both flavor and efficacy, the fresh product is superior to dried or processed forms.
