The word germicidal refers to therapeutic agents - including natural substances such as herbs, oils, or essences, or conventional pharmaceutical drugs, that kill germs such as bacteria and other micro-organisms.
Some dictionaries define germicidal as destroying specifically disease-causing micro organisms.
The meaning of the term germicidal is easily remembered from its form:
- The -cidal part of the word refers to the fact that this agent kills/destroys something, and
- the germ- part of the word indicates that the thing it kills is "germs".
