no one in LA. Cahill is the only reliable doctor left in the US. Yes, he can find protozoa and some helminths, and they are the most common. But he gives little meds, so you will have to take higher dose. My point is that most people who have stomach problems, losing weight rapidly, and colon pain, etc, is almost aways Protozoa (ameba most likely) or trichurica. These can be cured easily. But you need to take the proper meds
