Warning, if you are thinking of purchasing Nag Champa Fragrance Oil, which is actually produced in-house by Ancient Wisdom, then don't. The fragrance is absolutely nothing like Nag Champa. I returned one bottle for analysis and AW say that there's nothing wrong with the product and that I should expect it to be "slightly different" to the fragrance of Nag Champa incense. In my book "slightly different" shouldn't end up being nothing like Nag Champa! Needless to say, AW won't replace the product nor refund my P&P for returning the sample. Bottom line is, avoid this product and expect poor service.
