let me see if I can try to answer the question with out looking like a horny toad lol

ok when a woman OR animal starts her or it's period the body puts a out a signal of getting ready to come in to heat, now the in heat signal don't last that long maybe a hour or two at the most once it hits the air. lure makers have tried to mock that oil, that's were asafetida, lovage oil, valerian extract and tonquin , which all are one form or another is a passion ingredient when added to urine and or glands to mock that in heat reaction

one of the best man made synthetic passion ingredents that is deadly for deer, is the TONQUIN . mix a little with urine , glands or even by it's self will draw deer.


I have some trail pics in the small game board, look under the thread called yote gland lure testing with trail cam and see how many deer in the day light hours that came in to that lure with TONQUIN.
