whilst not a natural solution the following is usefull information in an expedition setting.
when on wanders in remote areas of the world I carry 10 x 500mg ciprofloxacin tablets.
as soon as the first signs of diarrhoea present themselves I take one 500mg tablet, often this brings the infection to an immediate halt.
if the symptoms persist you then you have a choice, ride it out (the majority of travelers diarrhoea is caused by E. Coli and will not last more than 24-48 hours)
Or if you do not have the luxury of the facilitys and time to let your body deal with it, take one 500mg ciprofloxacin every 12 hours for three days.
Ciprofloxacin will treat infections caused by E.coli, Campylobacter, salmonella, and shigella.
if symptoms persist after 3 days on ciprofloxacin then it is likley that you are suffering from Gardia or amobic dysentry (both will last around 14 days) in which case you will need to find your local pharmacy/doctor/expedition medic and you will be given 2 grams of metronidazole once a day for 3 days. (seek professionel medical help) absolutley no alcohol should be consumed whilst taking metronidazonle
be aware that ciprofloxacin should not be used only under professional medical supervision and with extra caution for pateints with a history of epilepsy, liver or kidney impairment, pregnancy, who are dehydrated, or young children.
Seek medical attention if the tempurature rises above 40 degrees or the fever lasts more that 48 hours, if the diarrhoea lasts more than 4 days, or if there is blood in the stools
in all cases people suffering from diarrohea should be kept hydrated with a mixture consisting of 8 level tea spoons of suger + 2 tea spoons of salt in a 1ltr of water, drink 400ml of this after every loose stool.
immodium and codeine phosphate only treat the symptoms they do nothing to combat the infection, I tend not to take either unless I have to. (I.E. on a long bus journey with no toilets
)
