Preheat the oven to 180 degrees F or its lowest setting.
Wash the ivy leaves, pat dry, and chop roughly. Place on a baking sheet and let dry in the oven for 1 hour.
Blitz the dried ivy leaves in a blender with the gin, juniper essential oil and grapefruit peel. Strain through a sieve into a bowl to remove all the fiber, squeezing the pulp with your hands to extract as much liquid as possible.
Heat the sunflower oil, emulsifying wax and beeswax in a heatproof glass bowl above a pot of boiling water until all the wax has melted. Take off the heat and slowly whisk in the ivy liquid, 1 tablespoon at a time. Pour into glass jars and let cool.
Apply to legs once or twice a day for up to 3 weeks. Then take a two-week break before using again.
For external use only. Do not use if you are allergic to ivy.
