It would be great to know how you found this out and if it is a cure or just reduces the blasto. I was diagnosed with Blasto last year and became very ill. Although my docs didn't believe the blasto was the cause I'm pretty convinced that it was. I took metronidazole just to "rule out" any parasitic infection according to my docs and the blasto is apparently gone now according to stool tests; however, I believe it is still there just in reduced numbers as I have had continuing nausea for almost a year. I have tried numerous herbal remedies which would help for a few days and then I would feel sick again.
Over the year, I have realized that one of the only things that helps the nausea is exercise. The effect seems to last for about 3 hrs after vigorous exercise. I wondered if it could have been due to extra oxygen in my blood and looked up and found that blasto is anaerobic (aha!). Last week, I began taking liquid oxygen and have had almost no nausea for a week-you wouldn't believe how exciting this is for me after almost a year of being nauseated almost every day! I'm not jumping to conclusions as I've had a few days break before but nothing this long or substantial yet.
I would also urge anyone with blasto to get their b12 level tested. mine was extremely low (135) and since I have taken supplements and it has raised up to 212, my energy has improved a great deal (which was what enabled me to get back exercising again in the first place). I believe the low b12 is what leads to the chronic fatigue and brain fog associated with this bug.
If you have more info about how you found this info, please elaborate. I am tempted to try the green tea but have been told to avoid caffeine by my internist...
