"Design a sleek and modern wellness product packaging for a premium brand. The product is a wellness supplement featuring the herb 'Kanna,' known for its calming and mood-enhancing properties. The design should emphasize simplicity, elegance, and tranquility, using a color palette dominated by majestic silver and effulgent royal blue. The packaging should have smooth, metallic surfaces with a subtle gradient effect, blending silver and blue seamlessly. Incorporate soft, flowing patterns or abstract motifs representing calmness, mental clarity, and nature, evoking the essence of the Kanna herb. Use minimalist, clean fonts for the brand name, ensuring 'Kanna' is prominently displayed in the center. The overall feel should evoke luxury, calmness, well-being, and trust, suitable for the wellness sector."
