4Herb paste?

Ive seen this offered a few times, Ive never tried or it even seen it. Can someone ive me a rundown on the product? 4Herb paste, Im guessing maybe a blend of whatever herbs/oils in a paste form used in rat/beaver lures?

My 4herb is a blend of four herbs with some glycerine and methylparaben to keep it from growing mold. It is the base for my Woodchipper and Muskrat#1 lures. I don't know if this is the same formulation as other 4herbs.

thanks Paul, its one of the few ingrediants I had not tried at one time or the other.. Ive been putting together a new oil's order and noticed several makers have it listed for sale now..
