In this entry, I want to talk a little bit about a concept that can get very sticky, and which may very well put me at the outer limits of credibility. Before I dig into the meat of the subject, however, I think I should remind everyone that THIS IS NOT A MEDICAL BLOG. NO INFORMATION PRESENTED HERE IS INTENDED TO DIAGNOSE, TREAT, OR OTHERWISE PROVIDE MEDICAL ADVICE FOR ANY ILLNESS, AILMENT, OR CONDITION. IF YOU HAVE A MEDICAL NEED, PLEASE SEE YOUR PHYSICIAN OR QUALIFIED HEALTH PROVIDER. ALL INFORMATION CONTAINED HEREIN IS STRICTLY IN THE INTEREST OF PRESENTING FOLKLORE AND PERSONAL OPINION.
Now that the big, scary, all-caps part of the post is done, let’s talk about the Doctrine of Signatures. I was actually rather surprised after our last episode to hear from several people that the concept of the DOS was unfamiliar to them. I realized at some point that the ideas founding the DOS were so internalized, and I was assuming that most people who worked with herbs had heard of those concepts. Now I’m thinking that I may have just been sort of lucky to have picked that information up early on (I know my mother shared a bit of that with me based on herbs she grew and I learned a lot of it from my first few years as a practicing neo-Pagan hanging around rock and herb shops).
So what is the Doctrine of Signatures? In this case, I think I’ll leave the general explanation to better folklorists than myself. First, I’m going to quote a somewhat neutral (though erring on the side of skepticism) article by folklorist Wayland D. Hand:
“Advocates of nature’s way in natural and organically grown foods, probably still have a lingering belief in the doctrine that for every illness with which man is afflicted God himself has provided a healing agent. All one has to do is to learn to seek out these wondrous plants. It was on this essential premise that the Doctrine of Signatures was enunciated by Paracelsus, Giambattista Porta and the early botanists. This theory is most ably stated by William Turner, an English botanist, who in his The New Herbal of 1551, wrote: ‘God hath imprinted upon plants, herbs, and flowers, as it were, a hieroglyphic, the very signature of their vertues, as on the nutmeg, which, being cut, resembles the brain.’ Writing a half a century later, Johannes Franck, one of the leading German botanists of his day, compiled a book which he called Signature, that is, a Basic and True Description of Plants Created by God and Nature. This doctrine went somewhat beyond the shape and color of plants to their activity and function. One of the earliest examples of this kind of sympathetic connection is found in the writings of Pliny the Elder who flourished in the first century, A.D. Calcifrage was recommended to combat the stone. This prescription comes form the fact that this hardy plant which could penetrate the fissures of the hardest face of a cliff, would certainly be able to break up kidney and gallstones, as the name of the plant itself suggests: calci-frage, ‘stone breaking.’” (Hand, “Magical Medicine,” Western Folklore)
Next, let’s look at a much older (and much more cynical) opinion about this idea, from plant folk-lorist T.F. Thiselton-Dyer, whose Folk Lore of Plants is something of a classic:
“The old medical theory, which supposed that plants by their external character indicated the particular diseases for which Nature had intended them as remedies, was simply a development of the much older notion of a real connection between object and image. Thus, on this principle, it was asserted that the properties of substances were frequently denoted by their colour; hence, white was regarded as refrigerant, and red as hot. In the same way, for disorders of the blood, burnt purple, pomegranate seeds, mulberries, and other red ingredients were dissolved in the patient’s drink; and for liver complaints yellow substances were recommended. But this fanciful and erroneous notion ‘led to serious errors in practice,’ and was occasionally productive of the most fatal results.” (Dyer, TFLOP, Chapter XVI)
The idea of plants bearing the divine mark which indicated their use is a very old concept. Hand notes that Pliny the Elder recorded such an idea, and it was debated even in his time with question to the validity of this method. The idea—in one form or another—appears in herbal medicinal systems throughout the world, including Chinese traditional herbalism and Indian Ayurvedic medicine. Many people swear by it, and a number of ‘yarb doctors’ have treated ailments with it for centuries with relative success. Yet at the same time, the doctrine has been misused, misapplied, or just plain wrong in some cases and has caused an increase in illness or injury.
I bring up the DOS at all because it’s so fundamental to New World magical concepts. The idea that God, the Creator, or some other spiritual force has set in motion a world which bears hallmarks of its design seems to have been taken as de facto truth among many early settlers in America, particularly poor folks with limited access to medical treatment. An entire profession of folk herbalism, or “yarb doctors” arose in the Appalachians, and similar practices (such as curanderismo in the Southwest) appeared elsewhere. In most cases, these medicine men and women did not make their primary living off of their knowledge of herbs and plants, but rather in many cases refused payment for such services, feeling that it was their God-given duty to render help when help was needed. Of course, such high-mindedness was not universal, but even in cases where money or goods changed hands, yarb doctors cost less than a typical doctor in most instances.
Determining which plants have which signatures is a strange and murky process. For instance, an herb with heart-shaped leaves might be good for treating a physical heart problem, an emotional disorder, working a love charm, etc. The hairy stems of mint might indicate that it has the ability to ‘prickle’ the lungs and stimulate respiration, or they might signal that rubbing mint on one’s scalp would stimulate hair growth. The tall and showy joe pye weed, which has the nickname ‘gravel root,’ is used to treat kidney stones—frequently referred to as ‘gravel’—but its hollow stems might signal a use in treating sore throats as well as problems of the urinary tract, which both feature hollow tubes leading to external orifices. In this latter case, we can see another important aspect of the Doctrine, in which many plants receive their folk names based on their folk medical uses (boneset, feverfew, eyebright, etc.). Critics of the DOS sometimes point out that the retroactive ascription of signs to the plants, such as noticing that joe pye weed has hollow stems and therefore would be good for urinary problems, does not indicate a heavenly marking of use, but rather makes for an easy mnemonic device for remembering what plants are good for what ailments. Further complicating the matter, some signatures are not visual markings, but rather based on sounds the plant makes when shaken, for example, or perhaps on a specific odor the plant emits.
There are also potential problems separating out a ‘signature’ from a legendary or mythical ascription of plant demarcation. Passionflower, which I’ve written about previously, is a good example of layered interpretation, with the numerical and color symbology of the plant being so closely linked to Christian mythology that the flower essentially contains a sermon. Was passionflower marked, given its unusual structure by a Creator to illustrate a story? Likewise, a number of plants are reputed to have some tie to the Crucifixion in Christian myth, such as the holly berry. Thiselton-Dyer also records a similar blood-staining myth related to poppies, in which they have been dyed by the blood of St. Margaret. In these cases, the plants are ‘marked,’ but not necessarily for use. They bear the signs of an interested and involved divine power, but are not strictly Doctrine of Signatures material since those signs illustrate a story and not a practical application. Yet, by a stretch of imagination, one could link the poppy’s use as an opiate and intoxicant to the story of St. Margaret, who famously battled a dragon. Since the use of poppy-derived-opium (and its relative, heroin) was known for a time as “chasing the dragon,” the connection does, by a bizarre happenstance, make some degree of sense. But was the flower marked with foreknowledge of the phrase, and thus was it pre-figurative? Or is all of this just strange coincidence?
It’s probably time for me to come clean, as I’ve been sort of dancing around my opinion on the Doctrine of Signatures. I’m a believer. Not a hard-and-fast, every-plant-bears-a-signature-and-medical-science-is-quackery kind of believer, but I tend to think that the DOS has some validity. My personal work with herbs and plants has led me to see the connections between their form and their functions. I don’t think that we necessarily understand every signature in every plant, and I do think that we frequently misinterpret the signs we see, but I do think that there’s an element of deliberate design within most flora that has to do with its use. This probably hedges a bit close to the Intelligent Design argument for some folks, and I don’t want to get bogged down in that discussion. I don’t make claims as to who marked the plants—perhaps they mark themselves in some way, for all I know. And I don’t necessarily think that I could wander into a meadow, find a foot-shaped plant, and use it to treat bunions and corns. I tend to agree with the skeptics about the retro ascription of plant signatures that human understanding of the plant signatures comes after we figure out what they are used for. But that does not diminish—to me—the idea that the design is implicitly connected to the use. It only emphasizes that we should be paying much more attention to what plants have to teach us, and to the hidden language of the world working around us.
So that’s my nutshell version of the Doctrine of Signatures. There are many authors who discuss this concept more handily than I have here, so please do some research and see what you think of the whole thing. Have you ever noticed signatures in plants (or even in animals, weather phenomena, etc., which are sometimes included in an extended version of this doctrine)?
Thanks for reading!

I think the DOS arose after people lost the abiity to commune with the plant spirits, which is how we learned most of the traditional remedies.
I would tend to agree with you on this, freemanpresson. Well said.
Very informative and creative. Thank you!
Thanks for posting. I find it funny you post since I was intending to research this after your recent podcast. Thank you, Cory. 🙂
Thanks for the info! I also hadn’t done much research on the DoS and was very interested in what you had to say.
Excellent treatment of this topic. I really enjoy this discussion, and do believe in DOS. I actually use it in my herbal practice.
Love this post! To me, the DOS is one part of the puzzle. I agree with Freeman that communication with plants has fallen by the wayside. I like the work Kiva Rose is doing with her “herbal energetics” which encourages sensory interaction with plants. Plants speak loud and clear in many ways (scent, visual, environment, taste, energy) we just need to learn to listen.
Thanks for posting on this. I hadn’t heard of the doctrine of signatures before last episode and am happy to know about it. 🙂
I’m a big fan of the DOS too, though my spirits make me say that sometimes the signs we see don’t match up with powers for a good reason. Each thing is a being, so its not unreasonable to assume that sometimes these beings get along famously with us, and sometimes not. When they do, we tend to get more from the plant / stone / animal / what-have-you. When they don’t, we tend to get less – you don’t help people you don’t like. Pretty much everyone gets jalapenos are hot, but some people get extra awesomeness from them, and some don’t. Some people get Aphrodite to all sorts of stuff unrelated to love, and some people are lucky to get even the basic love magic from her.
Which means we have to take DOS with a small grain of salt, to see if what we see holds up to what we actually experience – it’s more complicated than just the signs. Sometimes it’s about who we are, and who they are, and how the two meet (or don’t).
Also, just wanted to say hi (hi!) – new listener and fan. Found you via Sarah / Witch of Forest Grove. LIstening to old shows, and wish I could comment on some of them… 😦
