Why Do Spicy Foods Make Your Nose Run?

Original image

Hot sauces, curries, wasabi peas and other spicy treats turn you into a snot faucet. Why is that?

Capsaicin is the chemical found concentrated in the placental tissue of chile peppers and allyl isothiocyanate is an oil contained in plants like mustard and radishes (including horseradish). Plants use both of these chemicals as biological weapons against predatory animals. They irritate pretty much any soft tissue they come in contact with, which is what causes the wonderful burning sensation on your tongue. But they also cause the painful sting of post-chile-handling eye contact and a seriously runny nose. When your mucous membranes get hit by these chemicals, they become inflamed and go into defense mode. This means producing mucous to trap allergens and other undesirables, and keeping them out of your respiratory system by removing them via the nasal passage.

You might have noticed that if you’ve got a cold and are congested, the runny nose effect of spicy foods can make you feel a little better. Don’t be fooled by the healing properties of hot and sour soup and buffalo wings, though, because the relief is only temporary and really just makes things worse in the long run.

Capsaicin and allyl isothiocyanate’s irritation can cause the dilator naris muscle in your nose to temporarily allow more air to enter. Receptors in your nose then tell your brain that you’re breathing easier. It’s all an elaborate ruse, though, and when the effect of the heat wears off, you’re back to your old stuffy self, with plenty of extra snot brought on by your meal to boot!

What Is the Difference Between Generic and Name Brand Ibuprofen?

What is the difference between generic ibuprofen vs. name brands?

Yali Friedman:

I just published a paper that answers this question: Are Generic Drugs Less Safe than their Branded Equivalents?

Here’s the tl;dr version:

Generic drugs are versions of drugs made by companies other than the company which originally developed the drug.

To gain FDA approval, a generic drug must:

  • Contain the same active ingredients as the innovator drug (inactive ingredients may vary)
  • Be identical in strength, dosage form, and route of administration
  • Have the same use indications
  • Be bioequivalent
  • Meet the same batch requirements for identity, strength, purity, and quality
  • Be manufactured under the same strict standards of FDA's good manufacturing practice regulations required for innovator products

I hope you found this answer useful. Feel free to reach out at www.thinkbiotech.com. For more on generic drugs, you can see our resources and whitepapers at Pharmaceutical strategic guidance and whitepapers

Big Questions
Do Cats Fart?

Certain philosophical questions can invade even the most disciplined of minds. Do aliens exist? Can a soul ever be measured? Do cats fart?

While the latter may not have weighed heavily on some of history’s great brains, it’s certainly no less deserving of an answer. And in contrast to existential queries, there’s a pretty definitive response: Yes, they do. We just don’t really hear it.

According to veterinarians who have realized their job sometimes involves answering inane questions about animals passing gas, cats have all the biological hardware necessary for a fart: a gastrointestinal system and an anus. When excess air builds up as a result of gulping breaths or gut bacteria, a pungent cloud will be released from their rear ends. Smell a kitten’s butt sometime and you’ll walk away convinced that cats fart.

The discretion, or lack of audible farts, is probably due to the fact that cats don’t gulp their food like dogs do, leading to less air accumulating in their digestive tract.

So, yes, cats do fart. But they do it with the same grace and stealth they use to approach everything else. Think about that the next time you blame the dog.
