Have actually been and bought some of the cordial suggested i think the 40% cottees one suggested by Filo. I have been to bali numerous times before both with family and friends and none of us have ever been sick. Basically wanting to know WHAT the actual property is in the cordial that helps, thought it must be something to do with rasberry fruit themseves but theres No rasberry in it at all just flavouring plus apple juice etc Just otherwise wondering why we wouldnt use it here for gastro etc?? interested to know...
