piths

For example, some chimpanzees chew bitter piths of the medicinal shrub Vernonia amygdalina to treat worm infections—and even detour from their normal foraging routes to seek out the plants.

Grapefruit is used here, but if you happen on pomelos, grab a few: They’re much easier to peel and loosen from their piths.

More tangerine wedges cook alongside the bird in the same pan, their piths softening in the sauce that lacquers the bird.

They’ve also become a model for larger, multinational food companies, which are starting to realize that upcycling peels and piths can be good business.

"Yes—that's where they piths 'em," said the Tramp, quite in love with his conceit.
