Want to build trust? Try Lavender!

"new study published in the journal Frontiers Psychology suggests that the calming scent of lavender—as opposed to more stimulating smells like peppermint—is capable of fostering interpersonal trust. Scientists have long known that certain aromatic compounds can have an effect on a person’s cognitive or psychological well-being, but this is the first time they’ve found a direct link between a particular smell and the phenomenon of trust."
