Scientific Test

I had heard about this stuff but never seen it in the UK.
Then, whilst dutifully doing the grocery shopping, came across it in our local Co-op, complete with special offer.
I felt that it was my public duty to conduct a proper test to see if it is:
a) the promised elixir combining two of the most stress relieving substances know to woman, or
b) undrinkable, or
c) neither of the above.
Preliminary results are in and it seems that, purely in the interests of science of course, the study may need to be extended ;)
