From the maker:

With a recipe that reads more like a medieval elixir of herbs, plants, roots, barks, spices and flower seeds. A bottle of Galliano begins it’s life with the meticulous sorting and quality control of some 30 herbs, spices and plant extracts. This creates a perfectly balanced hand crafted artisanal spirit.

To this day the Galliano recipe remains a guarded secret. Here is just a handful of the extracts: Mediterranean Anise, Juniper, Musk Yarrow, Star Anise, Lavender, Peppermint, Cinnamon, Vanilla.
