Historically, various cultures, including the Adirondack and Sami people, have consumed tree bark during times of famine, proving its potential as an emergency food source. But the critical question remains: can you eat bark in a survival situation today, and if so, how do you do it safely?

Historically, various cultures, including the Sami people of Scandinavia and several Indigenous peoples of North America, have utilized tree bark as a food source, particularly during times of famine. This practice raises a modern question: Is there any nutritional value in tree bark for humans, and is it a viable food source?

Foraging history shows that indigenous peoples and early explorers relied on natural resources, including tree bark, for sustenance during lean times. This practice has sparked curiosity about whether modern-day survivalists can get nutrition from tree bark.

Studies of Scots pine inner bark have shown a protein content of approximately 3–10%. This confirms that yes, tree bark contains protein, though its quantity and biological function vary significantly depending on the species and season.

Historically, various cultures, including Scandinavian and Native American peoples, have relied on tree bark as a valuable food source. While you can't eat the rough outer layer, the nutritious inner bark, known as cambium, can be edible in certain tree species.

While most people associate maple trees with sweet syrup, historical records and foraging knowledge confirm that the inner cambium layer of the bark is also edible for humans. This practice, dating back to Indigenous peoples, reveals a surprising and nutrient-rich food source for those with the right knowledge and respect for the tree.

Tannins are phenolic compounds found throughout the plant kingdom, and their concentration can vary dramatically between species and even within different parts of a single plant. One species known for its exceptionally high tannin content is the Quebracho tree, which contains up to 25% tannin by weight in its heartwood.

According to the National Park Service, the manchineel tree, found in the Americas, is so toxic that rain dripping from its leaves can cause blistering, and burning its wood releases toxic smoke. This extreme example highlights the critical question: is tree bark toxic?

Dating back to 2000 BC, when Egyptians used it for embalming, cinnamon has been a highly prized commodity. So, what does cinnamon classify as, botanically and culinarily? While most know it as a spice, its true classification is more specific and fascinating, rooted in the bark of evergreen trees from the Lauraceae family.

Historically, various indigenous cultures and pioneers have relied on tree bark to supplement their diet during times of famine. But can humans survive on bark alone? The answer is complex, as it is only the nutrient-rich inner layer of specific, non-toxic trees that provides minimal sustenance for a limited time in a dire survival scenario.
