This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 荎 is uncertain. It combines 艹 (grass) with 至, but the original meaning and component function are unclear.
With grass 艹 over 至, picture a plant reaching its limit, but since the meaning is uncertain, treat this as a placeholder.
For チ, imagine a tiny grass 艹 reaching 至 for cheese: cheese -> チ, but remember the meaning is unclear.
