Greetings @CandiAnn,
That’s a great question- thank you for sharing it! I hadn’t heard that honey jars are specific to voodoo/hoodoo, was there a specific honey jar spell you found that was created by a voodoo/hoodoo practitioner? In that case, I can see how the spell might have traits that would be exclusive to those within the practice.
But if it was a general spell without specified ties to voodoo/hoodoo, then I believe that honey and similar sweetening agents in spellwork are universal ingredients- sweetening substances are common in many many types of love, friendship, and relationship spells. Also, honey is not like White Sage in that it has specific cultural ties and symbolism- honey has been used across civilizations dating back to Ancient Egypt:
Honey was revered in ancient Egypt, and until recently the oldest honey in the world was indeed found in an Egyptian tomb. That 3,000 years old honey had been placed in honey pots in the tomb of deceased pharoah King Tut to keep him happy on his celestial journey to the afterlife.
From Bee Mission: World’s Oldest Honey
Others may have differing opinions, but I do not believe that one culture or practice can claim exclusive use of an ingredient easily accessible and historically used by people around the world.
And while I didn’t personally write the Honey Jar Spell or Valentine’s Jar Spell (both of which are honey jars), as a fellow creator here I can attest that if they were written for Spells8 then they were definitely written to be used by any practicing witch or pagan, as opposed to only for those within a certain sect of magick 
I think it is very thoughtful and responsible of you to be wary of cultural appropriation, but in the case of general honey magick and spell jars using honey, I don’t think you have to worry. Any general sweetening jars should be okay to use. And if you’re set against that type of spellwork, then perhaps a Cleansing Spell could help to “clear the air” with your coworkers"?
These are just my thoughts on the issue- I’m sure those who know more about voodoo/hoodoo may have other thoughts for you to consider as well! As always, I am looking forward to hearing what the rest of the coven thinks about this 
Blessed be, Candice!
