Traditional Dragon-Shaped Herbal Grinder — Crafted from Pure Copper The dragon motif is exquisitely crafted and remarkably lifelike: the head and tail gleam with a brilliant gilded finish, while the body is intricately engraved with a pattern of fine scales. Paired with a circular copper grinding wheel, this device is designed for the precise grinding of traditional Chinese medicinal herbs. Why is it made of copper? As a natural metal, copper possesses relatively stable chemical properties; it does not readily react with the majority of active compounds found in traditional Chinese medicine, thereby effectively preserving the herbs' original medicinal potency and natural flavor. Furthermore, copper exhibits natural antimicrobial properties, ensuring that—even with prolonged use—it remains resistant to bacterial growth.
