Has anyone tried Kewra / Kewda floral water or Indian Attar?

Was wondering if anyone has ever used Pandaus odoratissimus, called Kewda or Kewra in India?

I found this at http://www.whitelotusaromatics.com/n...ers/kewra.html
- "...effect of refreshing and awakening tired brain cells. It is an oil of inspiration and creativity which seems capable of blasting away the cobwebs of lethargy or rejuvanating ones thinking process should it suffering from overwork..."

Others described its odour as: "reminiscent of vinegar, horseradish and hyacinth and very heady"

Any thoughts and uses?
