A 16% fall today is nothing to worry about....in their previous guise they fell from grace like an autumn leaf; when their trial was exposed.
( That was the last gasp for Phytopharm, then they bought into this Bio-co....but the exact details are too confusing to remember - DYOR.)
Phytopharm ( a different Co.) came to prominence because of an African plant "Hoodia" which by some accounts tasted horrible....but they went on a developed a pharma-drug by some magic and it was this that was being pushed around . . . but I don't recall it getting any worth-while Trial-status.... and I almost believe it was sold...or some deal was done with a Far-eastern company.... who may pay a royalty.....but one suspects not too soon . . and then any Patent protection will be lost . . . since you can find the same thing growing wild in the African desert . ..( that's the original story; but again it's been told/retold several times to confuse Investors like me.

2016- the IXI-sp has been steady, then rose and is now on its way back . . . but the NY ( 2017 ), may bring fresh hopes . . . and LT investors will start to see a return ( on their Investment...NOT in the Old-Ways, please.).
Whilst IXI is nothing to do with the previous business . . . maybe there lingers a whiff in the air.
Also, every Co. needs careful investigation by all investors IMHO.
Promises are easy.....delivery- Ah there's the rub. Good Lucj.

EDIT(17Dec2017)- Yawn... January AGM at 9:30 says "Stay-Away" IMHO - and still not much in the way of GOOD_NEWS, anyone?
