Is there a natural alcohol level in a human body

It is said that even if we are using natural remedies then also we are taking an alcohol in small amounts. But these quantities of alcohol can be eliminated within few minutes. It is a fact that apart from water if alcohol is used even in small quantity, it reaches to different parts of our body very quickly. When we take alcohol in any form, it passes from stomach into the small intestine. It is the place where it is rapidly absorbed in the blood and distributed quickly throughout the body. Even if it is taken in small quantity and in small concentration it affects our central nervous system.
