Notes on Meaning

The primary and modern meaning of lymph is strictly biological, referring to the fluid of the lymphatic system. Its use to mean pure water or plant sap is archaic and found primarily in historical or poetic texts. In medical and biological contexts, it never refers to blood or plasma directly but is a closely related fluid that interacts with them.
