This keepsake salt box is made of acacia wood that is naturally resistant to bacteria. The acacia’s durability, hardness, and evergreen nature made it a symbol of immortality for the ancient Egyptians and Hebrews. The tree is seen as a guardian spirit that protects and guides people. In the Bible, acacia wood was used to construct the Ark of the Covenant and other parts of the tabernacle. Acacia’s wood has also been associated with resurrection, re-birth and healing magic. The acacia’s flowers symbolize secret love.
