Sultan Al Akhdar (king of green) is what you could call the grandfather oil of the well loved popular oil Zamarad. The raw material for this oil was collected over a peroid of 1 year and is juiced from dark high quality agarwood from Sabah and Kelantan. If a oil was to represent the finest version of green smelling notes this would be it. Not a harsh or dark green but a vibrant sweet equatic green. The colour of this oil is a very light green and when applied to the skin feels like a chip on low heat sizziling away. The oil has a spicy element and also reminds me of oils from Borneo & Sri Lanka, it takes your nose on a real rollercoaster of a ride.
