Tim, the product is Honey-B-Healthy, advertised in Bee Culture.  It
is spearmint plus lemongrass oil compounded to be soluable in syrup.
Once when I didn't have time to use my usual Thurber Long Cage method
of introduction, I sprayed the queen and surrounding bees with H-B-H
in syrup and the direct introductin worked just fine.   Dan
