The invention involves a grinder safety cap suitable for medicinal items such as herbs or other consumable substances that may be desirably restricted from children, and which may require grinding and/or homogenizing before ingestion. The grinder safety cap is comprised of a cover shell and base shell, wherein the cover shell fits snugly over an upwardly extending top wall of the base shell. The base shell may have upwardly extending grinding protrusions, having sharp and/or serrated edges, capable of grinding, cutting, or otherwise reducing the particle size of a consumable substance. The cover shell may also have downwardly extending grinding protrusions. A consumable substance may be placed within a cavity or receptacle of the base shell, the cover shell may be placed over the top wall of the base shell so as to close the grinder safety cap, and the consumable substance may be ground by turning the cover shell.
