Renaissance painting of Leonhart Fuchs by Heinrich FullmaurerIn 1967, the Potomac Unit of The Herb Society of America initiated a project to publish a facsimile of one of the most significant herbals of the sixteenth century, De historia stirpium, or History of Plants, published by Leonhart Fuchs in 1542. The work, titled The Great Herbal of Leonhart Fuchs (De historia stirpium commentarii insignes) consists of two volumes. Volume one is an interpretive commentary based on three decades of research by the late Dr. Frederick Meyer, the late Dr. Emily Emmart Trueblood, and the late Dr. John L. Heller. Volume two is a facsimile of the Latin edition of the herbal.

At its inception, the project was under the leadership of Dr. Trueblood, a Potomac Unit member noted for her publication of the Badianus Manuscript, an Aztec herbal written in 1552, translated from Latin into English. As originally planned, Volume I was to include a life of Fuchs, a translation of Fuchs’ introduction, the contents of the herbal, and the botanical names for the woodblock figures of the plants in the herbal.

To help Dr. Trueblood, Dr. Meyer, a retired botanist at the U.S. National Arboretum, was invited as a consultant and advisor on botanical matters. After Dr. Trueblood suffered a heart attack and stroke making it impossible for her to continue, Dr. Meyer assumed full responsibility for the project. He was assisted by Dr. Heller, a Latinist and expert on Linnaeus at the University of Illinois, and with the continued support of the Potomac Unit members, the project moved forward. The sixteenth century was a period during which herbalism flourished and the illustrated herbal reached its maximum development. Of all the fine herbals that appeared at that time, the monumental work of Leonhart Fuchs, a folio with 511 beautiful woodcuts of plants, was one of the finest. The herbal was both an important medical document and a history of botany that enjoyed wide popularity throughout Europe for a long period. The last commentary on the herbal was published in France in 1862.

Title page of De Historia StirpiumLeonhart Fuchs, born in Bavaria in 1501, became one of the leading physicians of Europe. As a Renaissance humanist, philologist, Greek and Latin scholar, administrator, professor, and author, he may be considered the equal of Copernicus and Vesalius. In addition to his great herbal that went through 39 imprints during his lifetime (including German, French, Dutch, and Spanish translations), Fuchs published about 20 books on Galen and Hippocrates, and his anatomy treatise was second only to that of Vesalius. Fuchs was professor of medicine at the University of Tubingen for 35 years and was rector of the same university seven times. In addition to his writing and teaching responsibilities, he had a private medical practice and was father of ten children. He admonished medical men of his day for their botanical ignorance, writing that “one can find scarcely one in a hundred who has an accurate knowledge of even a few plants.”

Illustration of Heinrich Fullmaurer and Albrecht MeyerEvidence of his skill as a field botanist is found throughout his herbal. To illustrate his great herbal, Fuchs retained three artists. Albrecht Meyer drew the plants from life; Heinrich Füllmaurer transferred the drawings to the woodblocks; and Viet Rudolf Speckle did the cutting of the wood blocks. The illustrations produced by these artists, praised for their “simple elegance and naturalness of form” are among the finest produced in any sixteenth-century herbal. Of the many books authored by Fuchs, De historia stirpium was unquestionably his greatest love, his magnum opus. The fine printing and methodical layout, the organization of the subject matter, and the elegant illustrations make the herbal a real treasure.

Botanical Illustration of Capsicum in De historia stirpiumThere are many reasons for the significance of the Fuchs herbal. It is the first treatise on plants that can be called scientific. As one of the German fathers of botany, Fuchs is considered one of the founders of the sixteenth-century plant iconography. The 511 illustrations, all drawn from living specimens and nearly all identifiable to species, are a starting point for modern taxonomic botany, more than 200 years before Linnaeus. Fuchs’ illustrations were extensively borrowed, copied, or adapted for more than 458 years. Because of the excellence of the illustrations, it was possible to make the first accurate identification of many medicinal plants known from earlier periods. Many of the figures may be considered as historic types of plants figured by Fuchs and later accepted by Linnaeus. More than 100 plants are illustrated for the first time, including chile pepper, corn, French marigold, pumpkin, and kidney bean. The foxglove, a well-known cardiac plant, was first named and depicted by Fuchs in 1542.

Botanical illustration of Acanthus from De historia stirpiumFuchs aimed to include the complete history of every plant illustrated in the herbal, and for this reason, more than 40 Greek, Latin, and post-Roman authors were cited as sources for plant names. He also drew information on medicinal uses from the leading ancient sources, especially Dioscorides, Pliny, and Galen. Fuchs, himself, contributed additional information on medicinal use derived from local sources, which he included in a special appendix. The herbal also contained the first published glossary of botanical terms. An English translation is included in the new publication.

Scholars have praised the herbal of Fuchs as one of the most significant landmarks of pre-Linnaean herbal-botanical literature. [This] publication, The Great Herbal of Leonhart Fuchs, will be of value for scholars and students interested in the history of botany, medicine, pharmacy, Renaissance history, history of science, gardeners, herbalists, and others. Today, [over four and a half centuries] after De historia stirpium was published, it still has relevance as a medical reference. Over 80% of the plants illustrated in Fuchs’ herbal have relevance as medicaments in modern medicinal usage.

Dr. Frederick Meyer was a member of The Herb Society of America. An accomplished botanist, Dr. Meyer was both widely traveled and widely published. He wrote many taxonomic articles and books, including on the flora of Japan, the flora of Chile and the Juan Fernandes Islands, as well as publications on the cultivated plants of Europe. He studied the plants of Tierra del Fuego, as well as the ancient plants of Pompeii, and was the first to collect and study the cultivated plants growing along the Riviera in southern France.

Well, Well, What Do We Have Here? A Tale of Two Acorus Species

by Erin Holden

Tall, thin green leaves with a whitish-greenish spadixWhile doing research for a presentation on herbal uses of native plants, I decided to look more into a plant I’d learned about in herb school, sweet flag (Acorus calamus). This strongly aromatic aquatic plant has long been my favorite warming digestive bitter for those times when I overindulge in a huge meal (I’m looking at you, Thanksgiving). The flavor is warm, pungent, bitter, and spicy in a black-peppery way – the flavor sort of fills up your mouth and is warm all the way down to your stomach. But as I dug deeper into the research, I discovered I’d been wrong all this time about the origin of the Acorus species I’d been using. It turns out that A. calamus is native to Europe, temperate India, and the Himalayan region, while the native species is A. americanus (also called sweet flag), although the two species look so similar that even some scientists are unsure of which species they’ve studied and reported on. There still isn’t much consensus among taxonomists as to what differentiates these two – some even classify them as the same species (Boufford,1993; eFloras, 2008). Let’s take a deeper look at the similarities and differences between these two plants. 

There are many common names for sweet flag from all over the world (Daglan, 2014), many of which describe either the flavor of the root (like bitter, sweet, pepper) or its watery habitat:

Muskrat_eating_plant Linda Tanner via wikimediaAbenaki: mokwaswaskw (muskrat plant)

Ayurvedic Tradition: vacha 

Cheyenne: wi’ukh is e’evo (bitter medicine) 

Chinese Medicine: shui chang pú (watery flourishing weed)

English: sweet flag, calamus 

Hudson Bay Cree: pow-e-men-arctic (fire or bitter pepper root) 

Penobscot and Nanticoke: muskrat root

Micmac: ig gig’wesukwul (muskrat root)  

Pawnee: kahtsha itu (medicine lying in water) 

Many Native American names connect Acorus with muskrats. According to Sue Thompson’s dissertation on Acorus (as reported by Daglin, 2014): 

There seems to be “a closely linked ecological relationship between Native Americans trapping muskrats and using Acorus, muskrats eating Acorus, and Acorus. Muskrat feeding habits may in part be responsible for the dispersal of Acorus, and Native Americans may have intentionally planted Acorus both for their own medicinal use and to ensure food for the muskrat, which was economically valuable to them (Morgan 1980). Thus, the many Native American names for Acorus, which involve muskrat as a root word, may reflect an important economic and ecological relationship among man, plants, and other wildlife.”

A border planting of tall, thin green Acorus calamus leavesBoth species are perennial, grow in zones 4 to 10, have 1’–3’ tall iris-like leaves, and can spread 1’–2’. They bloom April through June, and like full sun to part shade. The inflorescence is a green spadix with no spathe (a spathe is a hood-like structure, like the white part of a peace lily). Both A. americanus and A. calamus are freshwater aquatic plants that grow in medium to wet soil and can grow in up to nine inches of water. They’re both easily propagated by root/rhizome divisions in the spring. Since they are aquatic plants, they can be used in water gardens, ponds, or rain gardens. They can also grow in regular garden beds as long as they get adequate water, so they’re very versatile if you’re looking for tall, straight leaves (Missouri Botanical Garden, 2022).

Although the two species look very much alike, there are some subtle differences you can use to tell them apart. A. calamus has leaves with one prominent vein and undulate (wavy) margins, does not produce fruit, and will “appear to have a shriveled ovary” in late summer, whereas A. americanus has leaves with two to six veins and smooth margins, produces small green berries, and has swelling ovaries in late summer (Dalgin, 2014).

There are also some unseen differences between the two. It turns out that A. americanus is a fertile diploid species and contains almost no phenylpropanoids, a chemical family whose members play a role in the flavors and aromas of cinnamon, cloves, nutmeg, and sassafras. A. calamus is a (mostly) sterile triploid (there are some populations of a fertile diploid phenotype in Asia that are morphologically distinct from the North American A. americanus). In addition, 13% of its volatile oil fraction is made up of those phenylpropanoids, one of which is β-asarone.

Botanical illustration of Acorus calamusThis chemical distinction is important, because β-asarone has demonstrated procarcinogenic tendencies (meaning it could metabolize into a cancer causing compound), and the FDA has banned the use of “calamus, calamus oil, or extract of oil in food,” although these studies used high levels of isolated β-asarone and not “suggested doses of the whole plant in terms of mg/kg of body weight” that an herbalist would recommend. However, since A. americanus has little to no β-asarone, it’s been suggested that this species is safe to consume (Dalgin, 2014).

Sweet flag is an important plant for many native peoples. One writer said it is “considered so sacred [to the Cheyenne] that only qualified Sundance priests [can] collect it,” and it “may be the most important herb in Penobscot pharmacology” (Dalgin, 2014). 

Historically, the Dakota used a paste on their faces to “instill fearlessness and provide stamina” in battle and chewed the rhizomes to enhance endurance “during the wars of the 20th century” (Dalgin, 2014). 

Other uses for the plant include: colds, flu, and sore throat; as a tonic; for intestinal pain and as a carminative (dispels gas); as a stimulant when tired; toothache; an analgesic for muscle cramps/spasm; and in ceremonial/religious rituals.

Tall, thin leaves of Acorus americanus growing along the bank of a streamColonists also used Acorus, and Eclectic physicians (doctors in the 1800s) incorporated it into their materia medica (list of medicinal substances). Eventually, it made its way into the first edition of the  Dispensatory of the United States in 1833 (Osol et al, 1833), which cataloged drugs used by U.S. pharmacists at the time. These groups used it pretty much the same way that Native Americans use it: as a carminative, for weak digestion and flatulent colic, as a sialagogue (stimulates saliva production) and as “breath perfume,” a warming aromatic bitter, and externally for ulcers that wouldn’t heal (Dalgin, 2014). 

Some modern herbalists who use both species say that, because of its higher volatile oil content, A. calamus targets the gastrointestinal system more specifically, while A. americanus has a “more balanced” action on the whole body—working equally on the gastrointestinal and nervous system, as an expectorant (which helps clear gunk from the lungs), spasmolytic (calms spasms), and antitussive (Daglin, 2014).

Now that I know about A. americanus and its different effects on the body, I’m interested in experimenting with the two species. I’ve also planted it out in the Native American bed in the National Herb Garden. I wonder if we should also invest in a muskrat.
