The pineal is a teeny endocrine gland deep inside your brain🧠 that modulates sleep-wake and seasonal cycles! Melatonin is the sleepy substance 💤 that regulates circadian rhythms and gets you to bed. Descartes thought the pineal was the seat of the human soul. The gland is also thought to be the third eye 👁and is named for its pine cone-like shape. If you need a bed buddy, check out our sleep-inducing brand new pineal plush!

St. Pituitary and St. Pineal wish you a Happy 🍀 St. Patty’s day 🍀 filled with endocrine gland gold. May the luck of these brain buddies be with you!

Pineal Gland is new to the Guts Gang and will be available in the shop starting next week!

We get a lot of great ideas from our customers here at I Heart Guts, but one of my personal favorites came from a dental student in Michigan, who begged us to make tooth t-shirts reading "Flossin' Ain't Just for Gangstas." Now while we still haven't made these shirts, I did make this one-of-a-kind drawing, along with a bunch of other special doodles -- including brains, lungs and kidneys -- all up for sale in the I Heart Guts store. Maybe you'll give one of these special friends a good home?
The pineal gland may be small, but it looms large in the minds of literary types. Did you know the pineal gland was a source of fascination to philosophers like Descartes, who called it the "seat of the soul"? The pineal gland captured the imagination of authors like Hunter S. Thompson, whose character Dr. Gonzo feared the psychoactive properties of pineal gland extract in Fear and Loathing in Las Vegas. "Man, I'll try just about anything, but I'd never in hell touch a pineal gland," Dr. Gonzo said in the movie version of the book. In his novel Broom of the System, David Foster Wallace's fictional corporation Stonecipheco worked on putting a pineal additive in baby food. More pop culture pineal stuff here.
