Haven't used it yet but...

First off, I could not detect a gingery smell when I opened the sealed bottle but, maybe that's how it is with Ginger. I did get it for it's medicinal effect, not for the smell (as I've gotten others such as: Orange, Lemon, Lime etc). I'm a big fan of Now Essential oils. So far, all the Now EOs I've tested have passed the "construction paper test". Put a drop of the essential oil on a piece of construction paper and let it dry for hours and, when it's totally dry, there should be no spot on the paper.
Another tip, I notice that the Now EO droppers release the oil drops quite quickly from the bottle, In the past, I've gotten Essential Oils from other companies and, it was (exaggeration to come) and aerobic experience :) to get a drop out of those bottles. So be aware of that with the Now EOs, especially when doing a recipe and you need to specifically measure out the drops. It can move quickly.
