Because it is a toxic substance with great affinity with fatty tissues. Do you know where there is fat? In neurons. More specifically in the myelin sheath, a kind of insulation that surrounds the axons and is composed of fat and proteins. Axons are the extension of neurons and function as a network that allows receiving and forwarding information between neurons and other cells. How does myelin absorb chloroform, the functioning of the central nervous system is compromised. Therefore, the substance causes mental confusion, torpor, sensation of anesthesia, dizziness, fainting and even death.
