Make the herbal honey syrup by combining honey, hot water, and herbs in a small bowl. Let steep for 5 minutes, then strain out the herbs and let cool.
For the cocktail, fill a shaker with ice and add the gin, lemon juice, and herbal honey syrup. For the mocktail, add only the lemon juice and herbal honey syrup to the ice-filled shaker; reserve the tonic water.
Shake vigorously for 15-20 seconds until well chilled and the outside of the shaker is frosty.
Strain into a coupe glass or a rocks glass filled with fresh ice. For the mocktail, pour in the tonic water after straining and stir gently.
Garnish with a fresh herb sprig and lemon wheel before serving.
