How Poisonous Is Lily of the Valley?

Original image

We don't want to spoil anything from this season of Breaking Bad for those who haven't seen it. But for the floss readers curious about lily of the valley, a plant that played a part in Sunday's season finale, we're happy to talk botany. Read on at your own risk.

So, what is lily of the valley?

Known by the scientific name Convallaria majalis, the lily of the valley is an herbaceous (the leaves and stems die at the end of the growing season and there's no persistent woody stem) perennial found in temperate areas of the Northern Hemisphere. The plant forms large colonies by spreading underground stems and appears above ground with upright stems called pips. The lily blooms in the late spring and has white, bell-shaped, sweet-smelling flowers and small orange-red berries.

The plant pops up in Christian legend several times. As the story goes, lily of the valley was formed from the tears of Mary as she wept at the crucifixion of Jesus, and grew from the blood shed by Saint Leonard of Noblac during his fight with a dragon. The lily of the valley was also used as the floral emblem of Yugoslavia and is the national flower of Finland

Is it really poisonous?

You bet. 

Toxicity is the plant's defense against animals eating its seeds. All parts of the plant—the stems, the leaves, the flowers and the berries—are extremely poisonous and close to 40 different cardiac glycosides have been found in the plant so far.

Glycosides are chemical compounds where a sugar is bound to a non-carbohydrate molecule. By increasing calcium stores in and around cells, cardiac glycosides increase the force with which the heart contracts and the volume of blood it can pump. This is not necessarily a bad thing, and these compounds have been used in medicine since the ancient Roman Empire to treat arrhythmia and congestive heart failure (today, the drugs Lanoxin, Digitek, and Lanoxicaps are made from a purified cardiac glycoside extracted from the foxglove plant). In quantities over the recommended safe dosage, though, cardiac glycosides can wreak havoc on your gastrointestinal, circulatory and nervous systems (more on that later).

That doesn't sound good. Could it be growing in my yard?

Possibly. The plant is widespread in the wild across Asia, continental Europe, England and the Appalachia region of the eastern United States. It's also a popular garden plant because of its sweet-smelling flowers and ground-covering ability, so it wouldn't be shocking to find it in a garden outside of its native range. Like, say, Albuquerque.

So I definitely shouldn't be eating it, then?

Not unless blurry vision, diarrhea, vomiting and nausea, disorientation, drowsiness, headaches, red skin rashes, excessive salivation, sudden alterations in your cardiac rhythm and possible death sound like your idea of fun.

Oh. Let's say that, er, a friend of a friend ate some. What's next?

Get to a hospital, where treatment will include ingestion of activated charcoal, breathing support, IV fluids, an electrocardiogram and a temporary pacemaker, depending on the nature and severity of the symptoms. They might also recommend not hanging out with people who make and/or sell meth.

Big Questions
Why Do Cats Freak Out After Pooping?

Cats often exhibit some very peculiar behavior, from getting into deadly combat situations with their own tail to pouncing on unsuspecting humans. Among their most curious habits: running from their litter box like a greyhound after moving their bowels. Are they running from their own fecal matter? Has waste elimination prompted a sense of euphoria?

Experts—if anyone is said to qualify as an expert in post-poop moods—aren’t exactly sure, but they’ve presented a number of entertaining theories. From a biological standpoint, some animal behaviorists suspect that a cat bolting after a deposit might stem from fears that a predator could track them based on the smell of their waste. But researchers are quick to note that they haven’t observed cats run from their BMs in the wild.

Biology also has a little bit to do with another theory, which postulates that cats used to getting their rear ends licked by their mother after defecating as kittens are showing off their independence by sprinting away, their butts having taken on self-cleaning properties in adulthood.

Not convinced? You might find another idea more plausible: Both humans and cats have a vagus nerve running from their brain stem. In both species, the nerve can be stimulated by defecation, leading to a pleasurable sensation and what some have labeled “poo-phoria,” or post-poop elation. In running, the cat may simply be working off excess energy brought on by stimulation of the nerve.

Less interesting is the notion that notoriously hygienic cats may simply want to shake off excess litter or fecal matter by running a 100-meter dash, or that a digestive problem has led to some discomfort they’re attempting to flee from. The fact is, so little research has been done in the field of pooping cat mania that there’s no universally accepted answer. Like so much of what makes cats tick, a definitive motivation will have to remain a mystery.

Big Questions
Why Do Baseball Managers Wear Uniforms?

Basketball and hockey coaches wear business suits on the sidelines. Football coaches wear team-branded shirts and jackets and often ill-fitting pleated khakis. Why are baseball managers the only guys who wear the same outfit as their players?

According to John Thorn, the official historian of Major League Baseball since 2011, it goes back to the earliest days of the game. Back then, the person known as the manager was the business manager: the guy who kept the books in order and the road trips on schedule. Meanwhile, the guy we call the manager today, the one who arranges the roster and decides when to pull a pitcher, was known as the captain. In addition to managing the team on the field, he was usually also on the team as a player. For many years, the “manager” wore a player’s uniform simply because he was a player. There were also a few captains who didn’t play for the team and stuck to making decisions in the dugout, and they usually wore suits.

With the passing of time, it became less common for the captain to play, and on most teams they took on strictly managerial roles. Instead of suits proliferating throughout America’s dugouts, though, non-playing captains largely hung on to the tradition of wearing a player's uniform. By the early to mid 20th century, wearing the uniform was the norm for managers, with a few notable exceptions. The Philadelphia Athletics’s Connie Mack and the Brooklyn Dodgers’s Burt Shotton continued to wear suits and ties to games long after it fell out of favor (though Shotton sometimes liked to layer a team jacket on top of his street clothes). Once those two retired, it’s been uniforms as far as the eye can see.

The adherence to the uniform among managers in the second half of the 20th century leads some people to think that MLB mandates it, but a look through the official major league rules [PDF] doesn’t turn up much on a manager’s dress. Rule 1.11(a) (1) says that “All players on a team shall wear uniforms identical in color, trim and style, and all players’ uniforms shall include minimal six-inch numbers on their backs" and rule 2.00 states that a coach is a "team member in uniform appointed by the manager to perform such duties as the manager may designate, such as but not limited to acting as base coach."

While Rule 2.00 gives a rundown of the manager’s role and some rules that apply to them, it doesn’t specify that they’re uniformed. Further down, Rule 3.15 says that "No person shall be allowed on the playing field during a game except players and coaches in uniform, managers, news photographers authorized by the home team, umpires, officers of the law in uniform and watchmen or other employees of the home club." Again, nothing about the managers being uniformed.

All that said, Rule 2.00 defines the bench or dugout as “the seating facilities reserved for players, substitutes and other team members in uniform when they are not actively engaged on the playing field," and makes no exceptions for managers or anyone else. While the managers’ duds are never addressed anywhere else, this definition does seem to necessitate, in a roundabout way, that managers wear a uniform—at least if they want to have access to the dugout. And, really, where else would they sit?
