(used only in compounds)
This rare kanji has no clear standalone meaning. It is used only in compounds, so treat its meaning as uncertain.
The historical origin of 蓚 is uncertain. It visually contains 艹 (grass) and 修, but the exact development is unclear.
The grass top 艹 over 修 suggests something related to plants or cultivation, but the exact meaning is unclear.
For シュウ, imagine a shoe (シュウ) made of woven grass from the top component 艹, tied to the idea of something crafted or repaired like 修.
