Exogenous

Toxins ingested from the environment are described as exogenous and include gases (such as carbon monoxide), metals (such as mercury<5>), liquids (ethanol) and numerous solids. Many neurotoxins are found in plant and animal matter found in nature; for example the neurotoxin aesculin is found in the horse chestnut (Aesculus hippocastanum),<6> and the California buckeye tree.<7> When exogenous toxins are ingested, the effect on neurons is largely dependent on dosage.
