Ketones and Ethers are known for their potential neurotoxic properties in certain concentrations and contexts. Ketones, such as those found in certain essential oils, can have significant effects on the central nervous system and may lead to neurotoxicity if misused or overused. This can manifest as dizziness, confusion, or other neurological symptoms, making it crucial to use these oils with caution.

Ethers, while typically considered less neurotoxic than ketones, can still exhibit neurotoxic effects under specific circumstances or when present in high concentrations. It is essential for aromatherapy practitioners to be aware of these risks and to thoroughly understand the safety profiles of the essential oils they use, especially those containing ketones and ethers.

The other families listed do not share the same level of concern regarding neurotoxicity. For instance, carboxylic acids and saponins are primarily known for their inflammatory or irritative effects rather than neurotoxicity, while esters and aldehydes are generally regarded as less likely to cause neurological issues. Monoterpenes and phenols, while they have their own safety considerations, do not typically include neurotoxic risks in the same way that ketones and ethers do. This knowledge is vital for ensuring safe practices
