Amebiasis
"Dientamoeba fragilis is notoriously difficult to get rid of. I&#039;ve tried anti-parasite herbs, Flagyl, Alinia, Tinidazole plus Yodoxin, and most recently, Tinidazole plus Paramomycin. The first time I had a very low dose (250mg) but I actually felt much better while taking it. After I finished, though, symptoms worsened again.  
The second time I took 1000mg, and that knocked out about 90% of my pain and other symptoms for about 4 months, until I took an antibiotic for a different infection.  Then it worsened again.  But overall I feel like Tinidazole worked far better than any of the other remedies (including the herbs, dietary restrictions and digestive enzymes)."
