theobromine earrings | sterling silver
Theobromine is the alkaloid that gives chocolate its character. The genus Theobroma was named by Linnaeus in 1753, from the Greek for 'food of the gods.' Mesoamerican cacao use predates that classification by at least three thousand years. The chemistry has been on human tongues for longer than most things on it.
The Science of Theobromine
Theobromine is a methylxanthine alkaloid, structurally one methyl group different from caffeine. Both compounds antagonise adenosine receptors and inhibit phosphodiesterase enzymes. Theobromine has weaker central nervous system effects but stronger cardiovascular and smooth-muscle activity, which is why it lifts mood without producing the jitter caffeine can. The compound is famously dangerous to dogs and cats. Their hepatic metabolism of methylxanthines is much slower than ours, so doses that pass through a human without effect accumulate to lethal levels in a small animal. The same chemistry that makes chocolate pleasant for one species makes it dangerous for another.
Who Reaches For This
There's a specific overlap of interests this lands for: chemistry curiosity and a chocolate habit, in roughly equal measure.
- biochemists and natural product chemists
- pharmacologists and toxicologists
- science teachers and educators
- chocolate-loving graduate students
Often gifted to a chocolate enthusiast who can recite the structural formula.

FAQ
Will a chocolate fan without a chemistry background get this?
Possibly not on first sight. The molecule is recognisable to anyone with biochemistry training, but a casual chocolate enthusiast might need it pointed out. The cleanest gift case is someone who has both chemistry knowledge and a chocolate habit, or who would happily accept a brief explanation.
Why is chocolate dangerous to dogs but safe for humans?
Dogs metabolise theobromine far more slowly than humans do. Their hepatic enzymes break it down at roughly a quarter the rate, so a dose that clears in a few hours for a person can take more than a day in a dog and accumulate to toxic levels. The mechanism (adenosine receptor antagonism and cardiac stimulation) is the same in both species. Only the kinetics differ.
What's the size, material, and hoop diameter?
15 mm theobromine charms in 925 polished sterling silver, nickel-free and hypoallergenic, on 17.5 mm sterling silver hoops. Free DHL Express shipping worldwide in 1-5 business days, all duties and taxes covered, 30-day "Love It or Return It" policy.
Is there a necklace version of theobromine?
Yes. The theobromine necklace exists in sterling silver and 18k gold vermeil, both at 24 mm. Different format, different size class. The earrings are smaller because they sit on a hoop rather than hang from a chain.
