Hibiscus petals lend a tangy and vibrant flavor, while orange zest and lemon balm add citrusy notes that complement it well. Cloves and lavender could contribute some aromatic and slightly spicy undertones, while licorice root adds sweetness and depth. The inclusion of stevia would offer a touch of sweetness without overpowering the other flavors. It seems like a refreshing and aromatic blend that would be perfect for a relaxing afternoon or as a soothing bedtime drink.
