I know Diarrex - took it sometimes in India. It is made from herbal charcoals and it can constipate. I had ordered the holarrhena (bitter oleander) and took like 2tsp 3xday (with the aegle -bael fruit) and it was enough to make my symptoms much less. Then ran out of the bael and took simply hollarrhena two times a day - like equivalent to 4 grams two times a day and now symptoms are not so repressed. So I assume that the dosage inside herbal formulas containing holarrhena are way below what I was taking and insufficient. Better get the herb in bulk and plan for a long siege; or make your own concoction.

Against protozoa, I also found Artemisia Annua - chinese Wormwood - is efficient against cryptosporidium (1000mg 3x day for 21 days);

and saccharomyces boulardii - friendly yeast - is also efficient to prevent recurrences. It also works against candida.

So am going to try a new mixture or then take the Nitaxonazide for three days. Chinese doctor thinks that my immunity may kick in and stop a recurrence.

Ayurvedic preparations from India are not quality controlled and potentially harmful. A recent study by clinical toxicologists in London revealed "heavy metal" contamination (TOXINS like mercury, lead, arsenic, etc.) in many samples. These contaminants are not always accidentally added, some practitioners actually believe they are beneficial to the patient's health!

Maybe there's a method... Take Ayurvedic medications and then immediately begin Liver Flushes for toxins! Or - Just don't do either!
