That sounds absolutely wonderful—just imagine the subtle aroma of fresh herbs mingling with the natural scent of the wood itself. Cedar or dark walnut would keep moisture at bay and add a subtle resin note that actually helps preserve your tinctures. I’d carve a shallow tray with a cork lid, maybe even line the bottom with a thin layer of beeswax so nothing sticks and the herbs stay dry. The grain will become a living map of your healing journey, and every time you open it, you’ll feel the calm of nature inside. 🌿
