Notes on Usage

• The Vietnamese name "xương bò" translates literally to "cow bone," but this is a folk name and does not describe the plant's physical properties. The connection is likely traditional and not literal.
• It is important to distinguish this term from the literal phrase "xương của con bò" (bone of a cow), which refers to actual bovine bones. Context is crucial for understanding.
