[Chinese medicine name]walengzi
[English name] Arcae Concha
[Source] Arca subcrenata Lischke, muddy Arca gran.osa Linnaeus or burrow Arca injlata Reeve is equivalent to several kinds of shells.
[Animal form] Large shells, oblique ovoid, extremely dilated, left and right shells slightly different, shell top inflated, slightly close, shell front obtuse, backward gradually narrow, behind the oblique side, shell with radial ribs 42 to 48 (often 43), smooth and neat, rib pattern and width of the intercostal groove equal, the surface of the shell is brown and hair, easily fall off. The inner surface of the shell is white, slightly gray at the top, and the edge is thick. It has long teeth that are equivalent to the radiating ribs and grooves on the shell surface, and have no radial ribs but very thin radiation stripes. The hinge section is straight and the hinge teeth are approximately 70. The taper from both ends to the center is dense, the coat marks and the marks of the closed shell muscles are obvious, the front closed shell muscle marks are small, nearly circular, and the latter is slightly larger, resembling a square shape. The mantle is thick and pleated.
[Origin distribution] Living in the shallow sea dozens of meters deep in the soft mud or muddy sandy bottom. Distributed in the coastal areas of China, the largest production in Bohai Bay.
[Harvesting and processing] Harvesting in spring and autumn, picking up and picking up in the shallow sand at the time of low tide, washing the sediment, cooking, and serving the meat, drying the shell.
[Herb character] Slightly triangular or fan-shaped, 7-9 cm long and 6-8 cm high. The outside of the shell is uplifted with brown fluff or has fallen off; the shell top protrudes and curls inwards; there are 42 to 48 radial ribs extending from the top of the shell to the ventral surface. The inner surface of the shell is smooth and white, and the shell edge has a recess corresponding to the straight edge of the shell. The hinge part has a row of hinge teeth. Quality. Gas slightly, tasteless.
[pharmacological studies] The experiment shows that the compound Wazizi granules is superior to cimetidine in anti-digestive ulcer healing and has the effect of inhibiting the growth of Helicobacter pylori, and its antibacterial ability is also superior to cimetidine.
[chemical composition] contains a lot of calcium carbonate, a small amount of calcium phosphate. Also contains a small amount of magnesium, iron, silicates, sulfates, chlorides and organic matter.
