Introduction: Survivalist's Guide to Edible Plants
Exploring the wilderness can be treacherous without the right nutrients. This requires a basic knowledge set and some basic skills when it comes to sourcing food. While nature offers a bounty of flora, not all plants are safe for consumption. Misidentifying a plant can lead to severe consequences, ranging from mild discomfort to critical poisoning. Understanding which plants are safe to eat and how to test for edibility is a crucial skill for any outdoor adventurer.
Section 1: Characteristics of Poisonous Plants
In the wild, certain visual cues may help identify potentially dangerous plants. You're first job is to inspect the source to avoid some basic characteristics. Here are some common characteristics to be cautious of and avoid if you can't identify it as safe:
Milky Sap: Many plants with milky sap, such as certain species of euphorbia, can be toxic. We will discuss later plants that have this and are edible.
Red Plants: In general, the color red in nature can serve as a warning coloration—known as aposematism—which suggests toxicity or danger. This is nature's way of warning potential predators, including humans, about the risk of consuming or interacting with these organisms.
Almond or Peach Scent in Woody Parts: This scent can indicate the presence of cyanide compounds, particularly in bitter almonds and some stone fruits.
Bitter or Soapy Taste: Plants that taste overly bitter or soapy should be avoided, as these flavors can indicate the presence of alkaloids or other toxic substances.
Thorns, Fine Hairs, or Spines: While not exclusively a sign of toxicity, these features can often indicate a plant’s defensive mechanisms against predators, including humans.
Old and Wilted Leaves: Old and wilted leaves can indicate several issues that affect the plant's overall health and the safety of consuming such parts.
Umbrella Shaped Flowers: Some of the most poisonous plants found in the U.S. are cow-bane and water hemlock, which both have flowers that grow in an umbrella shape.
White/yellow berries: As a general rule only about 10% of these will be edible world wide. The odds are heavily stacked against you with these.
It's important to note that these characteristics alone do not guarantee a plant’s toxicity nor do they apply universally. Many edible plants may exhibit one or more of these traits without being harmful. Proper identification through multiple sources is key.

Section 2: The Plant Edibility Test
When food resources are limited, and the identity of a plant is unknown, the plant edibility test can be a vital tool. It is important to remember that this test can only be done on one part of a plant at a time, prepared the same way each time. Make sure the plant is in abundance because this will take a while! This test involves several steps to determine whether a plant is safe to consume. If at any point during the test you start to have a negative reaction, stop the test and wait for symptoms to subside. You can now start the test with a new plant of different part of the plant. Here we go:
Look for Poisonous Characteristics: Use a list like the one above to rule out any possible poisonous characteristics. If it has the above, stop the test.
Separate the Plant: Isolate different parts of the plant—roots, leaves, stems, and flowers. One part may be edible while another is not, it's recommended to do this with a plant that is abundant and easy to procure.
Skin Contact: Place a piece of the plant on your wrist or inner elbow for 8 minutes and check for skin reactions.
Sap Contact: Break the plant open to allow for the sap contact just as in step 3. Wait 8 minutes and check skin for reactions.
Lip Test: Touch a small portion of the plant to your lips and again wait 8 minutes.
Taste Test: If no skin reaction occurs, chew a small piece of the plant (a teaspoon or less) for any immediate reactions but do not swallow. After 8 minutes swallow and wait 8 hours to any adverse effect.
Swallow: If no discomfort is felt, swallow a larger piece (about 1/2 cup) and wait for another 8 hours. If no adverse effects develop, the plant part is likely safe to eat.
This test must be conducted with caution and as a last resort. It’s also crucial to test only one part of the plant at a time, as some plants contain both edible and toxic parts.

Section 3: Understanding Plant Parts and Their Uses
Different parts of plants offer varying degrees of edibility and nutritional value:
Roots: Often nutrient-rich but must be cooked properly to neutralize toxins in some species.
Stems: Can be fibrous and hard to digest but boiling can help break down fibers and release nutrients.
Leaves: Generally the safest part to consume; cooking reduces the risk of irritants.
Flowers: Usually edible when blossoms are open; avoid wilted or unopened flowers.
Fruits: Typically safe when ripe; unripe fruits can be toxic or hard to digest.
For instance, dandelion is a common edible wild plant, where all parts—the roots, leaves, and flowers—are edible. However, the rhubarb plant’s leaves are toxic, while its stalks are a popular edible item.
Section 4: Tips for Safe Foraging
Foraging for wild plants can be rewarding but requires careful consideration to avoid disturbing or damaging the natural habitat:
Carry a Field Guide: Always have a reliable plant identification guide or an app on your phone. I use Flora Incognita and absolutely love it.
Learn Locally: Participate in guided tours or workshops to learn from experienced foragers or if you're in North West Florida come visit us at Six Point Survival.
Sustainability Practices: Be mindful of the environment by foraging responsibly and ethically.
Gearing Up: Essential Tools for Plant Identification and Edibility Testing
Here’s a list of recommended gear and resources to help you confidently forage for edible plants and recognize those to avoid:
This comprehensive guide by Samuel Thayer is invaluable for any outdoor enthusiast. It offers detailed information on how to safely identify, harvest, and prepare wild plants across North America.
A staple in the field guide genre, this book by Steven Foster and James A. Duke covers over 500 species of plants in detail, focusing on their uses as traditional medicines.
Turn learning into fun with these playing cards, each featuring a different edible wild plant, its characteristics, and uses. It’s a portable and entertaining way to familiarize yourself with edible plants.
This multitool includes a knife, saw, and other essential tools that can be handy for harvesting plant samples and preparing them for testing or consumption.
Keep a Rite in the Rain notebook handy to jot down notes on plant locations, characteristics, and your personal experiences with them. This waterproof option ensures your notes stay intact, no matter the weather.
These glow sticks are great for marking trails or locations where you’ve found edible plants, especially when foraging in dim light. They are reusable and environmentally friendly.
Conclusion
Arming yourself with the knowledge to identify and test plants for edibility is more than just a survival skill—it’s a way to deepen your connection with nature and enhance your outdoor experiences safely. Remember, when in doubt, it’s better to skip consumption than risk poisoning. We hope you've enjoyed our Survivalist's Guide to Edible Plants.
