Nature's Bounty?


One of the great things about this time of year is that, even after Halloween, people are racing to give you new ideas on ghosts, goblins, and how to kill people, with or without Nature's little helpers.  Two articles from Atlas Obscura leapt out to me:

First of all, consider the Manchineel Tree*.  Related to poinsettias, it's a nice looking tree, with fruit that looks kind of like the "little green apples" of the old Roger Miller song (older than dirt).

BUT:

You might be tempted to eat the fruit. Do not eat the fruit. You might want to rest your hand on the trunk, or touch a branch. Do not touch the tree trunk or any branches. Do not stand under or even near the tree for any length of time whatsoever. Do not touch your eyes while near the tree. Do not pick up any of the ominously shiny, tropic-green leaves. If you want to slowly but firmly back away from this tree, you would not find any argument from any botanist who has studied it.  Supposedly it killed Ponce de Leon.  (Manchineel Tree)

Gives new meaning to the Genesis admonition "if you eat of the tree you will surely die."  Now I think that the average mystery writer can think of a couple of ways of utilizing the Manchineel Tree, with the help of say, some rubber gloves and mass disposal of all cooking utensils, and I'll just leave that idea simmering away in the back of your minds.

The Manchineel tree (Hippomane mancinella) is found in the Caribbean, Central America, the northern edges of South America, and south Florida. Florida, of course, is host to other toxic plants, including the spotted water hemlock, (Cicuta maculata, a/k/a spotted parsley, spotted cowbane, and the suicide root) which looks like this:


https://en.wikipedia.org/wiki/Cicuta_maculata#/media/File:Cicuta_maculata.jpg

Occasionally mistaken for parsnips, this is considered to be North America's most toxic plant. "A quarter-inch of the stem is enough to kill a person" according to naturalist and botanist Roger Hammer, a naturalist and botanist. Unfortunately for us all, the range of the spotted water hemlock is the entire freaking United States, and I can show you a lovely crop growing up along the Big Sioux River here in Sioux Falls.

Or perhaps it's actually cow parsnip (Heracleum maximum), which grows everywhere, and is tall, herbaceous, and looks like a much larger, taller, thicker Queen Anne's Lace (daucus carota, a/k/a wild carrot).  According to Alaska's Poisonous Plants

"The sap of this plant contains various phototoxic chemicals that can make the skin (especially light skin) extremely sensitive to sunlight and more prone to sunburn. Skin contact with juice from the plant followed by exposure to sunlight can cause dermatitis, which can range from a mild, red rash to severe skin blistering."

Well, I'm not going to wade in to find out.  But people actually ate cow parsnips and lived.  From Wikipedia:

"The young stems and leafstalks were peeled and usually eaten raw, while early American settlers cooked the plant.[25] In terms of taste, texture, and nutrients, the peeled stalks resembled celery, which gave rise to the common name "Indian celery". The natives were aware of the toxic effects of the plant, knowing that if the outer skin were not removed, one would get an "itchy mouth" or blistering skin.[4][26] Pregnant women were warned away from the flower bud stalks to prevent newborns from asphyxiating when crying."

And this leads to (me, at least) the eternal question, how in the world did humans learn to eat some of this stuff?  

Take ginkgo seeds, from the ginkgo tree.  The ginkgo is the oldest living tree species on earth, an actual “living fossil” that's existed in their current form as far as the Middle Jurassic Period, or 170 million years ago (my emphasis added).  And they're very popular.  Their green fan-shaped leaves are aesthetic and pleasing, and turn a beautiful gold in autumn.  They can grow anywhere, through anything.  But a lot of people are severely allergic to their pollen, and their fruit stinks - "like vomit-laced poop" - and is inedible. (I would strongly advise against ginkgo supplements, no matter how hard they're pitching you.)  What you can eat is the cooked nuts - after a long, involved process requiring gloves and other precautions. And even then, the nuts contain trace amounts of a neurotoxin that can cause nausea and headaches, so you should only eat 10 nuts a day.  (Atlas Obscura)

But ginkgo is a more or less a garnish food.  What's even more fascinating to me is when people take something that is absolutely poisonous and transform it into edibility through a long, involved process of grinding, boiling, rinsing, leaching, etc. - how in the world did they survive to find out that the product would be edible?  Think about acorns and cassava.  

Acorns have bitter tannins, which interfere with the ability to metabolize protein. In order for humans to eat them, they have to be chopped and then soaked in several changes of water, until the water no longer turns brown. This can take several days. After that, they can be ground up and used like flour.

And there's manioc, a/k/a cassava.  Cassava root has cyanide in it, so it obviously has to be prepared carefully. Sweet cassava should be peeled, chopped up small, boiled until very tender, and the cooking water discarded. Bitter cassava (which is often grown because the animals won't eat it) has to be soaked in water for 4–6 days, boiled until tender, and then all the cooking water discarded.

Well, people aren't eating many acorns anymore, but cassava is the main carbohydrate for much of Africa and South America.  And people are still getting poisoned by it:  In 2017, 28 people died in Venezuela from cyanide poisoning from being sold raw bitter cassava roots instead of sweet cassava roots.  (They look alike, apparently.)  (El Pais)

Either way, whether it's ginkgo seeds, cow parsnips, acorns or cassava, what runs through my mind is a Monty Python routine:  

"Nuts, roots and seeds! Nuts, roots and seeds! Come and get your fresh nuts, roots and seeds!"

"Hey, there, my husband tried that root.  Took one bite and dropped dead, he did."

"Well, madam, we don't guarantee safety. You could try cooking it."

"Cook it? You didn't say nothing about cooking it."

"Haven't you heard? Everything's better if it's cooked. Or ground up a bit."

"My Aunt tried that. Ground it up cause she'd lost all her teeth. Took one bite and she dropped dead, too."

"Well, I've heard that some people are chopping it up, and rinsing it a few times first."

"How many times do you rinse it?"

[Shrugging] "Trial and error. Depends on the root. You got any relatives you don't like to try it out on?"

"Well, there's me husband's crowd from the shore. Bunch of clam eaters."

"And if that doesn't work, you could boil the hell out of it, and then drain it all off."

"It all sounds like an awful lot of work. Don't you have any potatoes?"

"Not for another three thousand years. Meanwhile, you get this right, and you could have a nice bowl of tapioca pud for your tea."

"Well, I suppose it would make a change...  I'll take two. But mind, if this doesn't work, I'm sticking with cattails."

Happy post-Halloween!




*Political Sidenote - the Manchineel tree is so toxic I propose calling Joe Manchin "Manchineel Joe".

  2. So it is, Janice. Humans will eat anything. I'm still amazed at the ingenuity of the first person to figure out that if you beat egg whites long enough, they change texture...

  3. Gabriel's Trumpet aka Angel Trumpet aka Trumpet Plant, a beautiful flower found in tropical areas is toxic if ingested and hallucinating if smoked like some Hawaiians do. At least two people who smoked it thought they could swim the Pacific from Maui to the mainland. Who decided to put it in a pipe or roll it up in smoking paper?

    I hear that the South Dakota sheriff who loaned the AG his personal car after the AG hit a "deer" on the highway, didn't find the "deer" until the next day and failed to initially see the Deer's sunglasses on the front seat in the AG's car with all the windshield glass has recently died of allegedly pneumonia or covid. Just as the investigation into the wreck is about to get going strong.

  4. Yes, R.T., the Sheriff of Hyde County died two days ago - in North Carolina. So far, no one is saying what was the cause of death, or where he was in North Carolina. Next week is the AG's impeachment hearing, and his testimony would have helped, to put it mildly.

  5. What an interesting article, Eve. I encountered those little green apples in the Caribbean, sitting under a manchineel tree on the beach of Sint Maarten. I didn’t know what the plant was, but I wasn’t the least tempted to try those little green apples. Whew.

    Eve, I grew up around old farmers and woodsmen who knew their woodcraft. They advised watching what animals ate (grazers and browsers). Another technique was to tie a bit of questionable but potential food to the inner arm. If it irritated the skin, avoid it.

    I’ve never tried poke salat, but Polk Salad Annie harvested it. Poke salat has prepared (boiled?) to get rid of toxins.

    A long ago girlfriend made acorn bread, blanching and re-blanching. (I’m not sure what blanching is, only that she did it.) It turned out pretty well.

    Eve, AHMM just purchased a story that contains a common plant that’s far more toxic than ricin. However, boiling it in milk renders it safe to make muti– a medicine.

  6. Leigh - I've had poke salat, prepared by others, not myself. (BTW, blanching is scalding something in boiling water for a short time, and pouring the water off.) So many strange plants out there that humans figured out how to eat...

Welcome. Please feel free to comment.

Our corporate secretary is notoriously lax when it comes to comments trapped in the spam folder. It may take Velma a few days to notice, usually after digging in a bottom drawer for a packet of seamed hose, a .38, her flask, or a cigarette.

She’s also sarcastically flip-lipped, but where else can a P.I. find a gal who can wield a candlestick phone, a typewriter, and a gat all at the same time? So bear with us, we value your comment. Once she finishes her Fatima Long Gold.
