@TheMuslimWitch It’s hard to tell what kind of ritual someone is doing unless you ask them. You can try to guess by looking at the ingredients and the imagery but you would still be guessing. After all, they can trick you into thinking that it’s a healing/positive ritual when it’s really not.
On the other hand, I agree with @Temujin_Calidius that secrecy is important. Nobody has to see any pentagrams unless you show them. 
There’s a reason why “to keep silent” is part of the Witches’ Pyramid. Quoting the Bible, don’t cast your pearls before swine. (Matthew 7:6)
