This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
捊 combines 扌 (hand) with 孚, which likely contributes sound. The exact historical development is uncertain.
The hand radical 扌 beside 孚 suggests an action, but the specific meaning is not clear from the shape alone.
For ホウ, imagine a hand holding a hoe: hoe -> ホウ, though the meaning of the kanji is uncertain.
