Dill is bound to Mercury & fire.  It is commonly used as a protection herb, and is often placed in a child's crib to keep him safe.  It can also be carried on the person in a sachet or charm, and dried seed heads are hung in doorways for protection purposes.

Dill is also used in love and lust charms and sachets.  Place the seeds in a muslin bag under your shower water, or bath water to make you irresistible to your lover. 

Dill is sometimes used in money spells, and can be carried on the person to attract money.
