"clearing" is not the same as detoxifying, detoxifying is making something toxic not be toxic anymore which rarely happens in the body
Detoxification (detox for short) is the physiological or medicinal removal of toxic substances from a living organism, including, but not limited to, the human body, which is mainly carried out by the liver. Source

And I'll add (again) this from How The Liver Works from The Canadian Liver Foundation
metabolizing alcohol and other drugs and chemicals,
neutralizing and destroying poisonous substances.
By definition, the liver is a critical part of the body's mechanisms to detoxify itself.
