This Black Pepper Essential Oil is a superb quality product, 100% pure and undiluted. Black Pepper has been used for a long time in the manufacture of fishing baits with piperine being the main active ingredient. Black pepper essential oil has a slightly spicy note to it and is used as a taste enhancer and digestive aid. It is probably the most common of all Essential Oils used within bait manufacture.Suggested dosage, 8-12 drops per kilo of mix (double in pop ups/hook baits), dependant on other additives used. As with all Essential Oils always use in a well-ventilated area.
