Place the kawakawa leaves in a pot with the water and ginger, bring to a boil then reduce down to a simmer for 15 minutes, allowing water to reduce by a ¼ cup.
Strain and serve with a squeeze of lemon juice. Stir in raw Manuka honey as the tea starts to cool to preserve its antimicrobial properties.
Notes
Kawakawa is endemic to New Zealand and easy enough to forage, however try a health food store for the dried leaf if you aren't confident with your plant identification
If using the dried leaf, use one teaspoon (up to 4g) per cup of water
