to be honest, i don't see why not......
Of course some are just absurd, like to change appearances and vanwuish made-up, television demons etc etc, but the spells in the show that could be used like the luck spell, the altar blessing, dominus trinus, have everything all the other spells we use. they're of the same structure, and they rhyme, ( "To bind ye spell every time, let ye spell be spake in rhyme " )
maybe will some slight changes, additions etc they certainly could be used in real practise.
Is this a joke! Charmed is a television show for entertainment.It is simply not true; none of it! It is Harry Potter stuff.
Stop seeing TV as "real". Not even the news bulletins are always true!
Charmed, like many other similar shows, is fiction.
