What is a pediculicide used for?

A pediculicide is specifically designed to destroy lice, which are parasitic insects that can infest the human scalp and body. These products typically contain chemical agents that are effective in killing lice at various life stages, including eggs (nits), nymphs, and adult lice. The use of pediculicides is crucial in addressing lice infestations, as these pests can cause significant discomfort and may lead to secondary infections from scratching.

In contrast, the other options relate to different functions: preserving body tissues generally pertains to embalming techniques; masking odors is more about using fragrances or deodorants; and promoting healing of tissues refers to treatments involving antiseptics or healing agents. These uses are not associated with pediculicides, reinforcing why the correct identification of the function of these products is so important in the context of lice treatment.
