Johannes Hartlieb's 1462 Kräuterbuch ("Book of Herbs") has drawn much scholarly attention for its unique characteristics and foundational importance in early German natural history writings. This notable manuscript not only replicates parts of Konrad von Megenberg’s Buch der Natur, itself a reworking of earlier herbals by Thomas of Cantimpré and Albert Magnus drawing on Arabic botanical handbooks, but also includes additional chapters detailing drugs derived from both plants and animals. The Kräuterbuch is distinguished by its 160 illustrations that accompany textual descriptions of the medicinal uses of various plants, making it one of the few fully illustrated herbals from the incunabula period of German history.
Despite its detailed illustrations, the cost of producing such an ornate book at that time suggests that it was not designed for practical pharmacological use. Library of Congress curators surmise that its primary purpose was to serve as a feat of visual representation rather than an accurate botanical guide. This hypothesis is supported by the fact that the floral illustrations, despite their beauty, were often too crude to allow for the accurate identification of plant species in nature.
Each chapter of the Kräuterbuch follows a systematic botanical classification, a method first developed by the Greek philosopher Theophrastus. This includes the name of the plant, information on its habitat, storage requirements, its medicinal effects on the body, and preparation recipes. Many of the medicinal concepts in the manuscript are based on medieval humorism and its doctrine of antithesis. For instance, cabbage is prescribed for headaches due to its cool and moist properties, which counteract the perceived hot and dry nature of headaches.
An interesting aspect of the Kräuterbuch is its accounts of animals exhibiting pharmacological knowledge. Deer, for example, supposedly rub themselves on pepperweed to dislodge hunters' arrows, while birds fed with disguised wild rue fall into a confused state, only recoverable with a shot of vinegar. Furthermore, some entries illustrate the use of plants like deadly carrots, which when applied, simulate leprosy — a trick supposedly useful for beggars to evoke sympathy.

The Kräuterbuch also enters the realm of the mystical and occult. For example, it includes a discourse on the mandrake root and its potentially fatal properties when harvested, a secret that Konrad von Megenberg advised should be kept from commoners. Hartlieb intensifies this secrecy when discussing verbena, suggesting that revealing its properties could incur divine wrath.
Born in Neuburg an der Donau at the start of the 15th century, Johannes Hartlieb was a court physician to Duke Albrecht III and later Duke Sigmund of Bavaria-Munich. He was a scholar deeply invested in the occult sciences, producing various works on topics ranging from enhanced recollection techniques to lunar divination and the power of names. His Buch aller verbotenen Kunst (Book of All Forbidden Arts) is a notable compilation, though it only details seven out of the promised ninety dark arts.
Hartlieb's contributions to literature also include translating Andreas Capellanus' magnum opus of courtly love into German and writing his own version of the Alexander romance. His diverse interests and achievements underscore his significance as a scholar and illustrate the broad scope of medieval thought and learning.
