water pepper
薔 refers specifically to water pepper, a plant. Its meaning is narrow and botanical, without broader abstract extensions.
薔 combines the plant radical 艹 with 嗇, which likely contributes the sound. The exact historical development of 嗇 is uncertain, but the character is used for a specific plant name.
The grass top 艹 signals a plant, and the dense lower part 嗇 looks like a tangled thicket. Picture water pepper growing in a messy, damp patch.
For バ, imagine a bar of soap made from water pepper: bar -> バ, and the plant's spicy leaves are used to make a cleansing bar.
