In my last blog post I examined coffee, the official beverage of NYC movers, shakers, and deal-makers and source of my favorite alkaloid, caffeine. This article is something of a sequel. While the consensus seems to be that a sequel is never as good as the original, I could muster a boatload of rabid Star Wars fans that would argue to the contrary. In any case, my sequel involves a frosty highball of fine aromatic gin, a juicy wedge of lime, and a comfortable seat in the shade—so how bad could it possibly be? The alternate ending is not so pleasurable—it features high fever, chills, profuse sweating, nausea, and a plethora of other equally objectionable symptoms. Intrigued? Confused? Let me elaborate.

Outside of a handful of plant geeks, most folks probably aren’t that familiar with trees of the genus Cinchona (pronounced “sin-cho-nah”). They are native to the tropical Andean region of South America with some species reaching north into Central America or west as far as French Polynesia. It’s a pretty tree by most standards. The big Cinchona pubescens in the Upland Rainforest house of the Conservatory bears large, soft, elliptic green leaves and attractive panicles of rose-pink flowers in spring. But truly—anyone can stand around and look pretty. What makes this tree so fascinating is what it can do.

The dictionary in my office defines an alkaloid as “one of a large class of organic, nitrogen-containing ring compounds of vegetable origin and sometimes synthesized that have a bitter taste, are usually water-insoluble and alcohol-soluble, that combine with acids without the loss of a water molecule to form water-soluble hydrochlorides, hydrobromides or…”

Need I continue?

Based on this definition, you might conclude that a blog post about an alkaloid is as exhilarating as collecting paperclips. Who could blame you? But alkaloids are nothing if not incredible. Mind you, this is coming from a man who, I’m ashamed to admit, spent much of college chemistry struggling to stay awake or attempting to secure a date with the brunette in the front row (both hopeless endeavors).

I’d be willing to bet most of you love alkaloids, too…or at least one in particular. It’s okay to admit an alkaloid is on your mind the instant you wake in the morning, during that staff meeting or interminable chemistry lecture. It doesn’t make you a bad person. Better than 80% of Americans are in the same boat, because eight out of 10 Americans simply can’t live without their daily coffee. As a recent and very reluctant convert to decaf, I can attest to the fact that without caffeine (an alkaloid!) the world is a far different place. Navigating The City that Never Sleeps without caffeine is like entering a NASCAR race on a rusty tricycle with a broken wheel and no seat. Sure, it can be done—but the risks are incalculable.
