Tissues are usually infiltrated with paraffin directly from an essential oil.

Explanation:
Embedding tissues requires infiltration with paraffin after the tissue has been dehydrated and cleared with a solvent that is compatible with paraffin. An essential oil can be used as a clearing agent in some protocols, but you do not infiltrate with paraffin directly from an essential oil. The wax must be the infiltrant, introduced as molten paraffin that gradually replaces the clearing solvent. So the statement is not correct.
