Notes on Meaning
The term "thymic acid" is largely historical or found in older texts. Its use has been almost entirely superseded by the term "thymol." When encountered, it refers to the same crystalline compound derived originally from thyme oil or produced synthetically. It is not a true "acid" in the common chemical sense (like citric acid or sulfuric acid); the "acid" in its name is a traditional designation.
