This is according to the Galenic system of humors, with the four temperaments described according to the state of their "bryne" or humors. This is followed by instructions for diagnosis of illnesses, again by referencing the state of a person's "bryne". A catalogue of illnesses and their symptoms. Some examples are alopecia, asthma, worms, cramps, flesh wounds, fluxes, and gout. The final index is an alphabetically organized list of various maladies, with reference to the entry number and first letter of appropriate medicines for each. The headings are often specific, such as "For wormes in the bely of chyldren" or "For broken synews." Usually, the "Grete Herball" is not the sole focus of scholarly work itself, but is mentioned in larger examinations of the history of herbals and botany. One exception is "The English Plant Names in The Grete Herball (1526) A contribution to the Historical Study of English Plant-Name Usage" by Swedish author Mats Rydén. It is a philological study focused on the herbal's English plant names, "...their frequency of use, provenance, typology, and synonymy (i.e. identity)...and changes in groups of names." It has been praised as filling a "shocking gap in English-language scholarship", but its potential use as a historical work has been questioned.
