Trich is a protozoan or germ similar to bacteria, so I would try something else before undergoing another fast and that is to take therapeutic doses of a good quality Colloidal Silver for about 3 weeks.
It takes about 4 days for the C' silver to build in your system to be effective in destroying pathogens of all kinds, and is a very effective way of doing so.
After this time-frame would I then undergo another fast of at least 10 to 15 days to make sure it is killed off completely.
