Its a good reason to do a liver flush.
If your scared regarding anything about it then I suspect that you have read or heard something that would cause you to be scared.
If you were only given the directions to do the flush, then you would not be scared to do it.
Pretend that you were only given the directions.
There is nothing to be scared of except good health.
The liver flush has been being done for thousands of years, maybe millions.
