Run !
This cannot possibly be pure, undiluted and undefiled essential oil.  I ordered this brand Lemon because a trusted family member told me they had purchased a product from Radha without problem.  I am not new to EOs.  I use lemon for everything.  I go through about 4 oz. a month for cleaning and laundry, and I thought I would try this.  My first mistake was straying from one of the brands I *know* is pure.  This is clear, not even a hint of yellow.  It smells of lemonade concentrate, in a bad way.  I'm angry at having wasted money, but I'm disheartened that this bottle claims it is 100% pure.  Of course, distilled water is pure too, so that may be the truth.  Only, in this case, I believe this oil is 100% pure OF lemon, as in, I don't think there's but a drop or two in there, along with whatever else has been used to fill the bottle.
