The Four Humors, Explained
HTML-код
- Опубликовано: 4 июн 2024
- The humoral theory was the main theory of health and disease for nearly 2,000 years. The idea that blood, phlegm, black bile, and yellow bile could influence your health and personality were the foundation for treatments like bloodletting and leeches, but also the first inklings of psychiatry. In this video, Patrick Kelly will explain the theory of the four humors in depth, and how it was replaced by cell theory in the 1800s.

A special thank you to my Patrons for making this video possible. I love getting to do these longer videos, but they take a lot of time to produce. Support on Patreon.com/corporis lets me take the time to go in depth on topics and not worry about cranking out content for the algorithm. If you're interested in supporting me, check out the link. Either way, have a lovely day!
What a humorous video!
buh-dum-chh!
I would like to personally thank you for making me chuckle, it made my day just a bit better :)
"Cry of the suffering organs" - I totally can relate to this, with my body had cried several times already
It's such a good line, right?!
@@PatKellyTeaches Indeed!
I first heard of the 4 humours aged 16 through Chaucer's Canterbury Tales, last century now 😊
Absolutely love your content! Just a couple corrections on the Chinese medicine side:
氣-qì does not refer to an "energy". The term literally translates to "air" or "vapor" and pertains to a classical Chinese worldview in which all things are composed of a single, fundamental substance which they regarded as a vapor.
"five elements" is a mistranslation of the term 五行 wǔ xíng-five phases and pertains to a theory describing how vapor moves particularly as it relates to geographical influences.
The theory goes that because everything is essentially composed of the same material, distinctions are not based on material composition but rather its behavior. In which case, The five phases is a model describing how this material moves. This makes it quite different from an elemental theory which proposes that all things are composites of a set of fundamentals. However, due to superficial similarities, the two models are easily conflated.
Thank you so much for your generous explanations, and kind delivery of feedback. I really appreciate it.
“Medicine daddy, sorry, father of medicine” got a real laugh from me. I feel humourily balanced
I think another important cause for the demise of the humoral theory was the Paracelsian rejection of the theory in favor of early Iatrochemistry, especially that which thrived in French Paracelsian schools in the 17th century: Pierre-Jean Fabre, Nicasius le Febure, Bernard Gilles Penot, etc. These developments would be critical for the rise of modern pharmacology as well.
FINALLY! Someone who lists their sources! It's hard to list a youtube video as a source for A collage paper, but with this I can actually give credit to people!
Thank you for informative video essay and integrity of source listing.
I take sources and citations seriously, so thank you for noticing. And make sure to check out some of the books listed in the description -- Passions and Tempers was a great source for this video
Thank you Theodor Schwann, your cells caused me a real headache, but your research played a pivotal role in having modern neurosurgeons be able to remove that headache!
Lol, came from my home town. He has a big bronce statue in front of the historical post office
I'm a pharmacy student and I wanted to understand the humor theory better so I clicked on your video and it's amazing!! Very well done on every aspect can't wait to binge watch all your videos ❤
Sarcasm, slapstick, yomamma jokes, stand-up. I think that's about it.
I thoroughly enjoy your videos each time they get released, I hope you know your content is top quality, keep up the great work!
I appreciate the kind words. I’m focusing on this channel much more this year
the way you correctly pronounced ibin sina was refreshing ❤️
Thank you! I mess up pronunciations constantly, so I make it a point to look for pronunciations of non-English names
Very cool video.
One thing I would add - blood-letting actually works for some people with certain diseases. Folks with Viking heritage have a genetic mutation that causes too much iron (“heme”) to accumulate. Since iron is toxic, they need to bleed often. They were warriors, so problem solved.
But, like in England, when the Norse invaders (the “French” Normans under William the Conqueror) settled and became a bit more peaceful, their offspring benefited from a medicine that, rightly or wrongly, “bled” sick people to “cure” them. Sometimes, these odd practices actually made scientific sense, in retrospect. 😊
I follow you from Syria
Thank you very much for this wonderful content
You are a great man❤️
I love hearing where people are from! Thank you for the nice words
Quite interesting;
Of course you're absolutely right but placebo/nacebo is amazingly real.
For example when I was sick with the flu, my mom putting her hand on my head to check if I was still sick was the bestest medicine I ever had.
Now I have to ask many times to get my fancy-pant physician-assistant wife to do it well.
Nopes, my wife doesn't quite replace my mom (go-figure ;).
From one educational content creator to another, let me thank you for your amazing work. This is just lovely and I'm so very thankful that you are producing this conten!
It's funny seeing my favorite religious/esoteric channel comment on my favorite medical history channel, especially after you just started covering Paracelsus!
Lovely video as usual Patrick.
Many thanks! More to come
I hope the algorithm promotes you more I found this channel yesterday and it’s amazing!!
Very nice. Very easy to understand. I'm just doing a little research on the humours for personal reasons, and this is one of the best videos I've found on it.
How do you only have 77,000 subscribers, your videos are perfection.
I was always curious about this. Thanks for explaining things so clearly. I always learn a lot from your videos.
You are amazing thank you so much ❤️
You didn't mention Al-Zahrawi(Abulcasis) or Ibn Al-Nafis, as these had great merit in medical sciences ،They created and composed many works
Thank you for the kind comment. I've heard of Ibn Al-Nafis before but not Al-Zahrawi. Can't wait to learn more about them
Lovely video as usual Patrick.. Great production value !.
You deserve millions of subs. The quality is superb.
Mr Patrick your videos are good and informative that i can't enough of them! I hope your channel keep growing bc you deserve it! Keep the good work!
Thank you for the kind words! Many more coming this summer
@@PatKellyTeaches excellent! I can't wait!😃
Been waiting so long for this masterpiece to drop. Thanks for helping us pick the right leeches :)
Man, I really appreciate the kind words, and more broadly, your long running support.
Great production value !
Thank you for your efforts
It’s a good brief overview of medical history
Amazing. Thank you. Subscribed
i'm not a med student or anything, but these videos are absolutely amazingly put together and very informative. really learned a lot here, thank you!
I hope some day in the future, there will be a video talking about how far medicine has come since the early 21st Century.
4:26 Missed opportunity to use the "Numa Numa" song
As a child of the 90s, I feel ashamed that I didn't
15:53 those silly little pointing hands made me laugh. All that effort when an arrow would have been fine. I love it.
Very helpful, thankyou.
Great video, great job.
Thank you!
Commenting to help you with the algorithm, gonna watch later! I was wondering when you'd get out a new one a few days ago lol 😁
I appreciate that. I had a rough autumn in my personal life, but now that I'm out the other side of it, I can put more energy into RUclips again. And this channel is getting my priority.
I enjoyed learning about humors 🌈
Subbed! Waiting on the Galen vid 😸
I'm disappointed, I was hoping to learn more about how to develop my comedic timing!
Lol, looks like you're off to great start already!
@@PatKellyTeaches Seriously though, this was very interesting. These medical techniques seem so ridiculous now, but it's interesting to learn how cutting edge it was within the philosophies of the time, helpful or no
Excellent video.
Thank you very much!
Some I knew, some not. Love it 😀 😍
I love this channel, but man the RUclips algorithm loves it too. I was watching a Star Trek Lore video and videos from this channel were the first 4 videos suggested… I don’t see the connection 😂😂
“Symptoms, then, are in reality nothing but a cry from suffering organs.”
- Jean-Martin Charcot
Your Channel is so underated
Ayyy thank you so much. More vids coming soon
Some say that bloodletting came from men seeing women get upset, have their periods, and then feel better, so they applied it to other things
I’m less than a minute in and completely distracted by that logo on your shirt - is it a flying pig?! Anyway, had to ask 😂 off to watch the content!
Hahaha, awesome comment. It's Brooks Brothers' sheep logo. Thanks for watching!
Entertaining and informative at the same time! Also, as a German I'd say you pronounced Matthias Schleiden and Theodor Schwann correctly. :)
A rare pronunciation W for me!
Love your video! But wouldn’t Matthew Baillie’s last name be pronounced like Bailey, not like Bale? I also noticed that the video section about Matthew Baillie is called “Bale”, and I was wondering if there was any source that said his name should be pronounced like Bale and not Bailey
15:42
Four hundreds years before William Harvey, Ibn al-Nafis discovered the pulmonary circulation: "The work of Ibn al-Nafis regarding the right sided (pulmonary) circulation pre-dates the later work (1628) of William Harvey's De motu cordis. Both theories attempt to explain circulation"
Only for colleagues:
The organism (the soma) contains two polarities, not only corresponding from right to left, but also from bottom to top, which differ in proportions and in the specialization of its cellular components. If we analyze it, it is very obvious that the cephalic structures have a breech correspondence; Let me explain what I just said... the brain with its circonvolutions correspond to the intestines, just as the brain is divided into two hemispheres, the intestine also has two parts (Auerbach/Meissner plexus), the upper cingulate corresponds to the lower one, the shoulder blades are the iliacus, the clavicle with the public bones, which would not both be in the front if there had not been happened a caudal rotation in the embryonic period, the mouth correspond with the anus that has its “dentate line” the Müllerian ducts that later will be either fallopian tubes or deferens ducts, etc.; correspond to the visual pathway, the seminiferous glands are the mammary glands, which along with the omphalo replicate the trigone, the scrotum corresponds to the internal part of the vagina, they present the same pattern of fissures when they contract, the lungs with the kidneys, the heart with the Pecquet cistern, also the muscle groups and the vessels with their vascular terrain correspond, the liver with the pituitary gland (portal system). Perhaps the unconscious would be the autonomous system, and the conscious is the autonomous system of the unconscious. Now I am combining this knowledge with Hippocrates' theory of humors, and the occult anatomy.
7:35 enlarged to show detail. Like the little insert box in the corner of the atlas that shows the city details
Well, now I’m gonna call Hippocrates Medicine daddy now
I don't make the rules 😎
"medicine daddy", LOL
I find this post to be very humorous......
Glad you liked that one. Father of Medicine is too bland
I’d love to know what, if any, current medical treatments you see are on their way out. Personally I think wound packaging, applying heat/ice to swelling, and default tooth removal will be antiquated before ling
is there a reason why you think those specific ones will disappear? super curious!
I just found your channel and I am a post-traditional student, so these are nice concise bites of information I can use to refresh and review.
How about a video on what ancient medicine got right.
I cannot get over it how ridolous humour theory is and how close it got to the truth, or at least it sounds like hormones.
I'm working on a video for August about ancient antimicrobials, and how some of them are pretty close to modern antibiotics.
Four or five thousand years ago, were either before, across, or after the flood in which case healthcare either exceeded ours or was in the stone ages. And a couple thousand, it was in the dark ages, or transitioning through the latter.
Natural herbal cures and a complete understanding of anatomy, plus basic cleanliness would have gone a long way to keeping at least some of them alive. Yeah, dissection and the invention of the microscope probably went a long way to getting things on track.
I hear 'Materia Medica' and I can't help but instinctively think, "Actually, it's called Restore Materia..." because of Final Fantasy 7. >_
Love the B.B. shirt!
Thank you! I love a good collar roll
This is probably a really dumb question, but I've been recently studying the various aspects of our eyes, and there are two parts that have to do with "humour": aqueous humour and vitreous humour. Since those are still considered as humors, does that mean the stuff these old scientists considered humors are still humors? Like is blood still considered a humor?
I'm insanely tired and probably not making sense. But I was just curious! I noticed that humor comes from a Greek word meaning juice or sap. And blood is sort of a juice, same with bile and phlegm... so maybe they are still considered humors, just not associated with these ideas of humorism?
Tbh i think the funniest thing is telling ppl we still do a lot of humoral remedies, just for very different reasons than we used to. Especially medical leeches i love medical leeches
very interesting to me how the balancing of humours resembles homeostasis
He is learning!
Why acetaminophen is around for so long if it's already debunked?
I saw this video, while my mbbs 😂
18:42 why do all the letter 's' look like 'f' ?
So, I'm not totally sure, but a quick Google search tells me that it was a way of denoting a long S sound. You'll see it a bunch when you read sources from the 16th and 17th century
i have seen it in many old manuscripts and written works, maybe that has something to do with the pronunciations. i also saw the same in Robert Hooke's Micrographia.
In the old script, the letter "s" was written in this way in the middle of a word - it's not a long "s" sound. At the end of a word it was generally written like a modern "s". This was only changed in the 20th century.
It's been a documented phenomena that Koreans buy significantly more spicy foods during times of economic recession, so they weren't completely wrong that spicy foods could change a melancholic constitution
We alternative (dissident) medical history!
Talk about irony, Empedicles the Impediment.

I'd imagine black bile was just bloody vomit.
🙏🙏🙏
It's kinda funny to think that they aren't as far off as we think
Medicine daddy 😂
Glad you appreciate that one

This is kinda weird. Are you April from bioZone?
I am naming one of my next two cats Sixtus. I went to school with a dude named Galen so I am not naming a cat Galen. 🤷🏻♀️ Maybe I will name a cat Humorous. Maybe Humorous the Sixtus. Humoral? We'll see. 😂
"Hello, these are my cats: black bile and yellow bile"
@@PatKellyTeaches 😂🤣😂
Wow! I hope I live to see the day that academia begins to regard virology as it now does humoral science. Thanks a lot for such an insightful retrospective! Fantastic quality of research on your part!
either and gas were thought of as two separate gases air being life giving bloodletting was used not that much or sparingly.this is sensationalizing it.either and fire representing mental problems or symptoms.
You know, I'm a bit of humorist myself ..
So on the one hand the humors model was a black box model that you basically analyze with input output or treatment vs outcome. The drive later was to understand the body better, but I would argue it gave us hundreds of years of misguided medicine because doctors would always assume they understand the machine when in fact they only grasped the most basic mechanics like the heart pumps blood which then to this day gives rise to stupid mechanical fixes, when the body is this evolutionary hypercomplex cellular machine. Germ theory was a big advance, but then again, the biggest advance was supporting the body itself with more complete nutrition, ie the analysis of the input to the body (vitamins etc), back to the black box model. Ie all the better health happening around the time of antibiotics was people got sick less because they ate healthier (fridge). I'm not even sure that sanitation (going back to germ theory) was such a big deal, because all this was discovered when people were still in a state of malnourishment, basically medicine as an alternative to food/immune system, which has misguided health care ever since.
Lmao the 4 humors is crazy
I know this is about medicine and science but you may want to warn that there is discussion of dog vivisection [other animals too?]. I had to take a break after that.
BTW I had fun reading the book: Things Come to Life: Spontaneous Generation Revisited, by Henry Harris on all of the classic experiments used to help get rid of the ideas surrounding spontaneous generation. A few of them went into the theories of disease and germ theory. The fights between famous supposed experts and the people that designed the experiments was wild.
😅
The four humours, dad, dark, edgy and cringey
😅 You forgot "dry"

guilty :P
how is it different from the chemical imbalance theory of mental disorder?
They applied it to everything without proper insight or a way to get proper insight.
@@jantuck6358 good one! i'll save it for children's birthday.
So… you’re not gonna tell me how these are funny? I thought this was gonna be a video about comedy writing or something idk whats so humorous about “black bile”… wait nevermind, thats pretty humorous
to much emphasis on the islomo age what is that Greek it's Greek to me.
Unfortunately you didn't give single logical reason to reject humoural theory. How Rudolf virchow pathology debunked humoral theory?
Hmmm let’s see if I can do better here. Humoral theory said disease was caused by humors, while cell theory and the pathologists said localized pieces of anatomy caused disease. Sorry for the lack of clarity.
I am physician treating people in Pakistan by herbal medicines. The system is called Unani (Greek) medical system. In this system we still use the ideology of galon and avenncina. Most of my patients are those who are incurable in allopathic system. In our system humoral imbalance is not the only cause of the disease. What are the reasons of local anatomical imbalances? Not germs only. We say most the times that humors are the cause of the local anatomy disorders but not always. Our system is close terrain theory.
The physician in Pakistan who is using the folk medicine to try to help those who are not helped by current allopathic medicine brings up an insight.
Isn't it curious how many well developed long-enduring health systems there are that prove helpful to their users? I am thinking not just of dietary, manipulative, exercise, meditative, or breathing systems, but also the more fully inclusive systems like Ayurvedic and Traditional Chinese medicine, among others, that include herbs, massage, acupuncture, movement like qi gong, and far more than I know about.
I don't know much about Ayurveda, but I have been astounded for years by Traditional Chinese medicine. What an amazing study of bodies/minds/spirits! It puts all our familiar "Western" medicine to shame. Of course, it's been around for thousands of years, as we know from Ötzi, the old man in the ice.
Lack of a *proper index?!?!* How dare you!! 🧤🧤🧤 Choose your second-- we shall meet at dawn, you blaggard!
Oh heck, there's a reason I don't write historical novels. I don't think any of that was accurate at all
I had a term paper focused around medicinal history during medieval Europe and man-I wish I had your video available then cause teaching myself the four humors for some reason did not land with me then, so I focused more on the advances in medicine and how religion and social aspects of society affected treatment 😭😭
The other student that had medical history during the era as their topic focused on the humors and honestly I was taken aback they found so much info surrounding it 🧍
I hope your videos gain in popularity.
The 4 humors: Larry, Moe, Curly, and Shemp 🤣😂
