Creepy Australian trees 'bleed' when cut open

On the outside, Corymbia opaca and Corymbia calophylla may look like completely normal trees — but slice one open, and you'll quickly discover an eerie secret.

Native to Australia, the trees, which are commonly referred to as red gum or bloodwood trees (for obvious reasons), exhibit a shockingly human characteristic: they "bleed" when they're cut into, or even shed bark.

Creepy Australian trees 'bleed' when cut open
😥🌳Bleeding trees in my city. They cut these trees and it seems to me they're bleeding... I'm sorry to see so many trees being cut and none being planted in their places. I'll miss these trees a lot, because they made my walk to work a lot better. 🌳😥#bleedingtrees #ecology #nature #environment #trees #bloodwoodtrees #bloodwoodtree #bloodwood #pterocarpus #pterocarpusangolensis

Tried a new bushwalking trail today. Came across one of these bloodwood 'bleeding trees' just when I was wondering if anyone would be able to find us if we got lost. Not ominous at all... 🥺 . . . #bloodwood #bloodwoodtree #bleedingtree #bushwalks #bushwalking #hiking #hikingtrail #hikingtrack #sydney #sydneywalks #sydneyhikes #walkingtracks #walkingtrails #walks #naturewalks #garigalnationalpark #newsouthwalesnationalparks

Desert Bloodwood tree aka Corymbia opaca. never thought I would get my hands on one, shoutout to @muss_k for looking out! Check out the blood sap oozing from the bark. This stump is already pretty dry and will serve as a great project. #bloodwoodtree #bloodwood #corymbiaopaca #corymbia #opaca #wood #deserttree #grain #oozing #blood #red #redblood #bark #woodworking #woodworkers #carpentry #grains #woodcraft #work #stump #exotic #woodley #woodenproject #woodenart #woodproject #chainsaw #woodcutting #beautifulwood #sap #carpenterslife

It is true: you are never too old to learn something new...this morning it was botanical lessons at the park 😳 . . Francesca was a bit taken & sad by the peculiarity of this tree: “mummy it looks like the tree is bleeding” . This tree is the “Corymbia Terminalis - Desert Bloodwood -. The orange/ red colours appears when dead barks have recently shed. The sap flows until it crystallises, covering up the hole in the bark. Another interesting fact : Australian Aboriginals collect this substance as bush medicine. They apply the sticky gum directly to sores or cuts and it works as an antiseptic. 😮 . Here you go....never too old to learn for sure 👌 . . #adventureswithkids #adventureswithchildren #melbourne #dendypark #bloodwoodtree #restorissimo #walktothepark #botanicallessons #tree #bleedingtree #australia #visitaustralia #nevertoooldtolearn #curiousity #adayout #parksinmelbourne #lovemycity #cometoaustralia #explore #exploringourcity #letthemexplore #enjoylife #bushmedicine #aboriginalaustralia #kidswholiketolearn #mydaughter #daddygirl #lovemyfamily #schoolholidaysmelbourne #photography

A tree says: A kernel is hidden in me, a spark, a thought, I am life from eternal life. The attempt and the risk that the eternal Mother took with me is unique, unique the form and veins of my skin, unique the smallest play of leaves in my branches and the smallest scar on my bark. I was made to form and reveal the eternal in my smallest special detail. H.Hesse #tree #bleeding #bark #pine #life #bleedingtree #nature #beauty #blood #resin

Of course, the "blood" seeping out of a damaged Corymbia opaca or Corymbia calophylla isn't anything like yours or mine — the thick, red goo is actually a gum called "kino," which just happens to bear a shocking resemblance to human blood.

Australian Aboriginals are known to collect the material, which gets its red color from an exorbitant amount of tannins, and use it as medicine to treat colds and other ailments. 

While totally harmless, the sap is definitely the stuff of nightmares for unsavvy outback explorers.
