How to use: Brew a tea from 1-2 fresh leaves (don’t overdo it, as it’s potent!) or use kawakawa balm for skin irritations.
🍯 Mānuka Honey
Why it’s amazing: Famous worldwide, Mānuka honey’s Unique Manuka Factor (UMF) comes from methylglyoxal, a potent antibacterial and antiviral compound. It’s a go-to for soothing sore throats and boosting immunity.
How to use: Stir a teaspoon into warm water with lemon or ginger for a comforting winter drink.
🌿 Kūmarahou (Pomaderris kumeraho)
