How to flush EtG out of body?

I've come across the topic of flushing EtG out of the body and I'm curious to know more about it. Can you explain what EtG is and why someone might want to flush it out of their body? What methods or techniques are commonly used to achieve this, and are there any potential risks or side effects associated with doing so? Additionally, is there any scientific evidence to support the effectiveness of these methods?
