The Herbarium: Sassafras — The Three-Faced Tree That Flavored a Nation

A Field Entry by Professor Eldrin Nightshade, Alchemist Extraordinaire
Classification: Sassafras albidum | Family: Lauraceae | Origin: Eastern North America

A PERSONAL NOTE FROM THE PROFESSOR

I want to begin with a confession that will surprise no one who has read the previous entry on sarsaparilla: I got these two confused for an embarrassingly long time.

Not botanically — the Professor's field notes are meticulous, and Smilax ornata and Sassafras albidum are not, in any meaningful sense, similar plants. One is a thorny vine. The other is a tree. One grows in Central America. The other in the forests of Virginia. They are related only in the way that all things with complicated histories and optimistic marketing are related: by the particular energy of a century that believed strongly in botanical cures and asked very few follow-up questions.

What confused me was the cultural overlap. Both roots were shipped to Europe as syphilis cures in the 1500s. Both became patent medicine staples. Both ended up in the same glass, more or less, when root beer was invented. Both were ordered at frontier saloon bars by men with strong opinions about horses. And both have names that sound, to the uninitiated ear, like variations on the same word.

They are not. And the differences, once you look closely, are considerable.

But we will get to that. First: the tree itself. Because sassafras deserves to be understood on its own terms before it is compared to anything.

I encountered it properly for the first time in colonial Virginia, during what was supposed to be a brief temporal reconnaissance and became, as these things do, a four-hour detour. Mortimer has filed it under "Unauthorized Excursions, Vol. 1" — which is to say, sassafras was among the first plants to derail the Professor's schedule, and it has never entirely stopped.

A local herbalist handed me a cup of brewed root bark and said, with the serenity of someone who had never once entertained doubt: "This cures everything."

It did not cure everything. But it smelled like something that should cure everything — warm, sweet, spicy, ancient, and somehow both familiar and completely new. I stood in that Virginia forest for a long time afterward, looking at a tree whose leaves could not agree on a shape, and thought: this one has a story.

It does. Several, in fact. Here they are.

THE TREE THAT CANNOT COMMIT

Sassafras albidum is a deciduous tree of eastern North America — found from southern Ontario through the eastern United States and into Mexico, growing in forest edges and disturbed ground with the cheerful opportunism of something that has never worried about where it belongs. It reaches 30 to 60 feet at maturity, with deeply furrowed reddish-brown bark and a root system that spreads through underground runners, colonizing ground quietly and persistently in a way that the Professor finds both admirable and slightly alarming.

But the leaves. We must discuss the leaves.

On a single sassafras tree — sometimes on a single branch — you will find three entirely distinct leaf shapes growing simultaneously:

• Unlobed: a plain oval. Unremarkable. The botanical equivalent of a firm handshake and no further conversation.
• Mitten-shaped: one lobe extending to the side, as though the leaf began as an oval, reconsidered, and added a thumb as an afterthought.
• Three-lobed: symmetrical, three-fingered, the kind of shape a medieval illustrator would draw in the margins of a manuscript next to a note about dragons.

All three. Same tree. The botanical explanation involves juvenile growth patterns and responses to light conditions. The Professor's explanation is that sassafras simply has a complicated inner life and has decided, after considerable reflection, not to be pinned down.

Mortimer eventually came to retrieve the Professor from the Virginia forest. The Professor was still staring at the leaves. This is, in retrospect, an entirely reasonable response.

The entire tree is aromatic — bark, leaves, roots, and twigs all carry that warm, spicy, root-beer-adjacent scent. This comes primarily from safrole, a phenylpropanoid compound concentrated most heavily in the root bark, which has had — as we shall discuss — a rather eventful regulatory career.

A HISTORY OF EXTRAORDINARY AMBITION

The Indigenous Foundation

Before European contact, sassafras was woven into the botanical knowledge of numerous Indigenous peoples across eastern North America. The Cherokee, Choctaw, Ojibwe, and many others used the root bark for fever and pain, the leaves as a culinary thickener, and the wood for its durability and scent. This is not incidental background — it is the foundation on which everything that follows was built, and it deserves to be named first.

The leaves, dried and ground, produce filé powder — a fine, earthy seasoning that thickens and flavors gumbo across Louisiana and the Gulf Coast to this day. It is one of the more quietly elegant culinary legacies in this archive: a tree that cannot decide on a leaf shape turns out to produce, in powdered form, a cornerstone ingredient of an entire regional cuisine. The Professor finds this deeply satisfying. Mortimer uses it in something he calls filing cabinet soup. The Professor has chosen not to investigate further.

The Colonial Export Frenzy

When European explorers arrived in the 16th century, they encountered sassafras and did what they invariably did with interesting American plants: declared it a cure for syphilis and shipped it home in quantity. Sir Francis Drake brought it to England. The Virginia Company listed it among the primary commercial motivations for colonial settlement. Ships returned laden with root bark. The price was extraordinary.

It did not cure syphilis. It smelled wonderful and made a pleasant tea, which was perhaps sufficient justification for the trade volume, if not the marketing copy.

The gap between the claims and the evidence was, the Professor notes, staggering — and entirely consistent with the era's approach to botanical medicine, which might be summarized as: it smells medicinal, therefore it cures things, therefore we will not be taking questions.

The Patent Medicine Era and the Birth of Root Beer

The 18th and 19th centuries brought sassafras into the patent medicine mainstream as a spring tonic — the belief being that winter's accumulated humors required something aromatic and slightly medicinal, and sassafras delivered both admirably. Families brewed it seasonally. Children drank it. It was considered wholesome in the vague, optimistic way that many things were considered wholesome before controlled clinical trials became fashionable.

And then came root beer.

The original root beer — brewed in American homes and commercialized in the mid-19th century by Charles Hires, among others — was a genuinely herbal preparation, and sassafras root bark was its defining ingredient. That warm, sweet, slightly medicinal, deeply nostalgic flavor that most people associate with root beer? That is sassafras. Specifically, that is safrole. For roughly a century, sassafras root beer was simply root beer — the standard, the original, the thing itself.

And then came 1960.

The Safrole Question

In 1960, the FDA banned safrole as a food additive, following studies in which laboratory rats developed liver tumors after being fed safrole at doses that were, by any reasonable calculation, far in excess of what a human being would consume through normal tea drinking. The root beer industry reformulated. Artificial flavoring approximating the original became standard. The root beer most people drink today is a reasonable facsimile — but it is not, strictly speaking, the same thing.

The Professor notes, for the record: safrole is also present in smaller quantities in black pepper, basil, and nutmeg, none of which have been banned. He presents this as context, not as regulatory advice. He is an alchemist, not a toxicologist, and he recommends consulting appropriate guidance for your region before brewing anything from root bark.

What he will say is this: the flavor that defined an entire beverage category for a century came from a tree that grows three different leaf shapes simultaneously and was named by Spanish explorers who thought it cured syphilis. The Professor finds this cosmically appropriate.

SASSAFRAS VS. SARSAPARILLA: A FIELD COMPARISON

Since the previous Herbarium entry covered sarsaparilla in some depth, and since these two roots have been confused with each other for approximately five centuries, the Professor feels a direct comparison is warranted. Consider this a corrective to history.

Origin: Sassafras is a North American tree. Sarsaparilla is a Central American vine. They share a continent in the broadest sense and nothing else geographically.

The plant itself: Sassafras grows upright, reaches 60 feet, and has three kinds of leaves. Sarsaparilla winds around whatever it can find, stays low, and has thorns. One is a tree with an identity crisis. The other is a vine with commitment issues. The Professor finds both relatable.

The flavor: Sassafras is warmer, spicier, more immediately recognizable — it smells like root beer because root beer was built around it. Sarsaparilla is earthier, more mineral, faintly vanilla-adjacent, quieter in its complexity. Sassafras announces itself. Sarsaparilla introduces itself gradually and then stays.

The history: Both were shipped to Europe as syphilis cures in the 1500s. Both became patent medicine staples. Both contributed to root beer. But sassafras was the dominant flavor — the one that defined the category — while sarsaparilla was more of a supporting ingredient, more prominent in the marketing than in the glass. Sarsaparilla got the saloon reputation. Sassafras got the FDA ruling. Neither outcome is entirely fair.

The regulatory status: Sarsaparilla root is sold freely as an herbal product. Sassafras root bark contains safrole, which is banned as a food additive in the United States. Sassafras leaves — the source of filé powder — are entirely unaffected by this ruling and remain in wide culinary use.

The legacy: Sarsaparilla is the root that people think made root beer. Sassafras is the root that actually did. Both have been somewhat misrepresented by history, which is perhaps the most accurate thing that can be said about either of them.

The Professor's preference: He declines to choose. They are different instruments playing different notes, and the question of which is better is less interesting than the question of what each one actually is — which is, in both cases, considerably more than the history books suggest.

WHAT REMAINS

Sassafras persists. It spreads through underground runners with the quiet stubbornness of something that has survived considerably more than regulatory controversy. The leaves continue to be ground into filé powder. The trees continue to grow three leaf shapes simultaneously. The scent, when you crush a leaf or snap a small twig, is immediate — warm, sweet, ancient, and somehow both familiar and irreducible.

It smells like something that has been important for a very long time. Because it has.

The Professor, on his last visit to a sassafras grove in the Virginia piedmont, stood among the mitten-shaped and three-lobed and unlobed leaves and thought about colonial ships, patent medicine bottles, root beer fountains, and FDA hearings, and found the whole arc — from miraculous cure-all to banned substance to quietly persistent forest tree — to be one of the more complete stories in the archive.

Some plants have simple histories.

Sassafras is not one of them.

Disclaimer: Professor Eldrin Nightshade and the lore of The Seventh Atelier are fictional. Sassafras has a genuine and well-documented history, but safrole — its primary aromatic compound — is banned as a food additive in the United States and several other jurisdictions. Filé powder, made from the leaves, is entirely safe and widely used in cooking. The Professor does not recommend brewing sassafras root bark tea and accepts no liability for unauthorized excursions to colonial Virginia, gumbo-related incidents, or the lingering philosophical discomfort of a tree with three kinds of leaves.
