Edible Wild Plants – Field Guide UPDATED

Wild plants are plants that are normally found in nature, growing spontaneously without the need for anyone to grow or care for them. Although they may not always seem like it, there are many edible wild plants. Do you want to know more about these edible wild plants? Join us in this article where we give you names and examples through photos.

How To Know If a Wild Plant Is Edible

If you need to check whether a wild plant is edible, you can apply a method traditionally used in survival manuals and tactics.

  1. First, separate the plant into its different parts: there are edible roots, edible fruits, edible wildflowers, and edible leaves, but just because one part of the plant is edible, doesn’t mean that all of it is.
  2. Then clean the separated parts for possible parasites or insects: if they are inside, discard the plant.
  3. The next step is to rub the plant against your wrist or elbow.
  4. Then crush it and hold it against another area of skin for about fifteen minutes.
  5. Wait 8 hours to see if it causes any kind of reaction: if there is any kind of allergic reaction, discard it.
  6. Boil or simmer the plant in water if you have access to such tools: if not, you will have to taste it raw. Very slowly, hold a small sample between your lips for about 180 seconds. If you notice a burning or any kind of reaction, discard the sample again.
  7. The next step is to put the sample on your tongue, without chewing, for 15 minutes, again watching for reactions. If nothing happens, chew for another 15 minutes, watching for changes or adverse effects.
  8. Finally, swallow a small sample and wait 8 hours without eating or drinking anything but water. If you notice something negative, induce vomiting without hesitation and drink plenty. If nothing happens, try a reasonable amount of the plant, such as a quarter cup, prepared in the same way.

This is a survival mechanism in case of need, and you must be very careful when doing so, as you expose yourself to serious complications.
