Sassafras Oil – Extreme Snark

We’ve chosen Sassafras oil, which sounds like something your grandma would recommend for a cough, but actually doubles as a chemistry experiment that can wreck your liver. Charming. 🌿

What is sassafras oil (and why did it get itself banned)?

Sassafras oil is extracted from the sassafras tree and contains a compound called safrole. Safrole is the star of this disaster: it’s been shown to be carcinogenic (cancer-causing) in animal studies and is also, for bonus points, a precursor chemical used in making MDMA.

So you’ve got a substance that:

Can damage your liver
Is linked to cancer
And helps people synthesize illegal drugs

Regulators looked at that résumé and said, “Absolutely not.”

When was it banned?

In the United States, sassafras oil (specifically safrole) was effectively banned in 1960 by the FDA as a food additive.

Before that, it was used in:

Root beer (yes, your nostalgic soda used to contain a mild chemical hazard)
Traditional medicines
Flavorings

Then science showed up, ruined the party, and suddenly everyone had to switch to “safrole-free” versions. Progress is so inconvenient.

How many people died?

Here’s where it gets frustratingly vague.

There isn’t a clean body count like some dramatic poison story. Sassafras oil didn’t rack up headlines by dropping people instantly. Instead, it worked the slow, boring route:

Long-term exposure linked to liver damage and cancer
High doses can cause vomiting, hallucinations, seizures, and death

There are documented cases of poisoning, but no widely agreed global death total. Translation: it’s dangerous enough to ban, but not flashy enough to come with a neat kill scoreboard.

So if you were hoping for a dramatic “X thousand deaths” number, sorry. This is more of a quietly harmful over time situation. Less horror movie, more slow paperwork-induced doom.

Is it banned worldwide?

Not universally, because of course humanity can’t agree on anything.

United States: banned as a food additive (safrole illegal in consumables)
European Union: heavily restricted
Other countries: regulations vary, but safrole is generally controlled due to toxicity and drug manufacturing concerns

So while you might still find sassafras-related products, they’re typically safrole-free. The dangerous part got kicked out, like a problematic guest who ruined the evening.

Does it have medicinal properties?

This is where folklore and reality start arguing.

Historically, sassafras was used for:

“Blood purification” (which sounds impressive but means nothing scientifically)
Treating colds and fevers
Digestive issues

Modern science says:

Any minor benefits are overshadowed by toxicity risks
There is no strong evidence supporting meaningful medicinal use
Safer alternatives exist for literally everything it was used for

So yes, it had traditional uses. And yes, we stopped using it because we enjoy having functioning organs.

Final reality checkIt didn’t get banned because of paranoia. It got banned because:

It can cause cancer
It can damage your liver
And it has a side hustle in illegal chemistry

Still, there’s something almost poetic about it. A sweet-smelling oil that once flavored root beer and promised healing… turned out to be a long-term liability wrapped in nostalgia.

Nature really does have a sense of humor.
