Japanese boat-shaped pill/herb grinder - Mortar and pestle - Copper

A solid copper, boat-shaped traditional Chinese medicine grinder (*huiyi cao*). This complete set—comprising the grinding trough, wheel, and handle—is in excellent condition and features an exquisite design.
It weighs 995 grams, stands 10 cm tall, and measures 21 cm in length.
The boat-shaped body rests on three feet and is adorned with rivet-style decorative motifs. A seal-script inscription is present on the base, and the piece displays a rich, authentic patina. As a traditional tool for preparing medicinal herbs, it is functional for grinding ingredients, while also serving as an ideal decorative object for a traditional Chinese medicine clinic, a study, or a collection focused on the culture of traditional Chinese medicine.
