Reading the Green Language: The Doctrine of Signatures in our Smokies
Ever noticed how some plants seem to 'tell' you what they're for? Or that they just show up and keep announcing themselves to you when you need them, even if you don't realize it yet?
Long before modern labs, our ancestors in these Tennessee mountains practiced the Doctrine of Signatures. They believed that a plant's shape, color, or habitat was a divine 'signature' of its purpose. While it's often called a myth today, and people actually make a living 'debunking' it, as an herbalist, I've found that these signs often can point us toward incredible chemical truths.
For instance, here locally, we have in our neck of the woods here:
Bloodroot (Sanguinaria canadensis): Break the root and it "bleeds" a bright red sap. Traditionally used for blood-related conditions, we now know it contains powerful alkaloids like sanguinarine.
Yellowroot (Xanthorhiza simplicissima): That vibrant yellow inner bark was a clear sign to old-timers of its use for "bilious" (liver/gallbladder) complaints. Today, we recognize its berberine content, which supports exactly those systems!
Boneset (Eupatorium perfoliatum): With leaves that look like they’ve been "set" right through the stem, it was the go-to for break-bone fever.
Whether you see it as a divine map or a brilliant mnemonic tool used by the "yarb doctors" of old, the Doctrine of Signatures reminds us to slow down and really look at our Green Allies. Nature isn't just a resource; it's a conversation.
These conversations with our Green Allies lead us into relationships with the green world. A world where the plants are our Ancestors, and it is their mission to help us. They WANT to help us, because we are their descendants. Cultivating these relationships with our Green Allies, gives us incredible tools to work with in healing, or in just nourishing our bodies to even prevent the need for healing. What was that old saying? "An ounce of prevention is worth a pound of cure."
In the Heroic model of Allopathic Medicine, some will use herbs to treat symptoms only. While that is certainly possible, you will miss out on the deeper nourishment and profound healing that comes from actually communing with these plants as their caretaker, their gardener, their friendly forager. You learn so much more from the plants themselves this way.
Here's my own personal anecdote on one of my favorites: Mullein (Verbascum thapsis) that grows in plentitude in many areas but not in the higher elevations as much. The wands produce literally millions of seeds when tells you that it has a fairly low germination rate. That said, it CAN, and often does become invasive, so it must be introduced and managed responsibly.
Mullein kept cropping up in the strangest places one year when I had a persistent, (leaf mold related) cough that just wouldn't go away. Not only is mullein useful in smoking blends or (well strained) as a tea, the tinctured first year root is excellent for urinary incontinence associated with bronchial spasms that causes coughing to the point of bladder leakage. For most these symptoms go away with the ailment, but the older we get, the more we might have need of this ally's gentle action on the bladder to help with temporary, or even chronic urinary incontinence.
Mullein's leaves look like lungs both in their shape and texture. This was key in helping oral cultures such as the local Cherokee and other First Nations peoples discern the best use for this attractive biennial plant.
The flowers, though some prefer Greek Mullein or Moth Mullein flowers because they are larger and easier to harvest, are also useful paired with garlic and infused in almond oil for earaches in children and to treat ear mites in pets. You can also dip the seed wands in wax, or pitch or kerosene to create an attractive torch for camping. Mullein has a lot to offer us.
In spellwork, powdered mullein leaves are a substitute for graveyard dust, in European folklore it was knowns as "Hag's Taper" or "Witch's Candle" or simply "Candlewyck" when the stalks were dipped in tallow for funeral processions. It's greyish 'dusty' appearance and its ability to thrive in disturbed soil lent itself to this use and led to it's association with graveyards. The Appalachians are essentially an open air library for our plant helpers, if we just pay attention.
