[EX Q]: This tea is stale.  I have had this brand and kind of tea many times, so I know how it should taste.  It's dated Jan. 2013, but it must have been stored improperly.  It has no fragrance and no taste.  Even the teabag paper looks yellowed.  It is worse than supermarket tea.  I cherish my breakfast tea, so am very disappointed, especially having bought six boxes of this useless stuff.  I tried to give it no stars, but that's not allowed, so I gave one for prompt shipping.
[EX A]: Negative

[EX Q]: Google "propylene glycol" to find out why.  I bought this product, along with several others, without running the ingredients by my wife first (a nurse of 30 years) she was surprised when she noticed it.. we went a googling, and poured my $50 order down the drain afterwards.  There's "pure" and then there's "not so much".....  from the website:  [...]  Propylene Glycol  A cosmetic form of mineral oil found in automatic brake and hydraulic fluid and industrial antifreeze. In the skin and hair, propylene glycol works as a humescent, which causes retention of moisture content of skin or cosmetic products by preventing the escape of moisture or water. The Material Safety Data Sheet warns users to avoid skin contact with propylene glycol as this strong skin irritant can cause liver abnormalities and kidney damage. Also used in:    Tyre sealant   Rubber cleaner   De-icer   Stain removers   Fabric softener   Degreaser   Paint   Adhesive   Wallpaper stripper  I wrote the company about this concern and they never responded....
[EX A]: Negative

[EX Q]: I love the aroma and the taste of the fruit and vanilla combo, and the addition of ginseng for an added energy boost rounds this tea out nicely for me. It's a sweet tea, which makes it a wonderful healthy alternative to desert after dinner.  I see that others didn't like it, but it's really a matter of personal taste...different courses for different horses!
