How can you tell if a wild fruit is edible?

Try not to try it yourself, you really don't have anything to eat in the wild, just see if there are any small animals to eat.

The biggest problem with eating wild plants is how to identify poisonous or non-toxic. The easiest way is to cut a hole in the collected plants, put a pinch of salt, and observe whether the hole changes its original color, and the discolored ones are inedible.

The Atlas of Chinese Wild Vegetables summarizes several relatively simple identification methods:

Take a small part of the plant, chew it with your front teeth in your mouth, and taste it with the tip of your tongue for bitterness, spiciness, and other peculiar smells. If the smell is strong, it may be poisonous, so you should spit it out immediately before rinsing your mouth. Astringency indicates tannins, while bitterness may contain harmful substances such as toxic alkaloids and glycosomes.

Because some harmful substances (tannins, alkaloids) can be dissolved in water, so the plant can be scalded in boiling water for 5 6 hours or cooked, and then taste whether there is still a strange smell. At this time, if the bitterness and strange smell still exist, it should not be eaten.

If a large amount of precipitation is produced in the boiled plant soup, it means that it contains heavy metal salts or alkaloids and is inedible. If the boiled soup produces a large amount of foam after shaking, it means that it contains saponins and is inedible.

The feed that can be eaten by ordinary livestock is basically edible by humans. It is a popular feed for several types of livestock, and it is certainly non-toxic.

In the absence of all the above identification tools and means, you can also try a small amount of a certain plant, if there is no dizziness, nausea, headache, abdominal pain, diarrhea and other poisoning symptoms within 8 12 hours, then eat a large amount.

Identifying whether a plant is poisonous or not is complex, and the most reliable way is to carefully identify it according to the atlas of edible wild plants compiled by the relevant authorities. However, in the wilderness, they can only rely on the types, distribution and feeding methods of edible wild plants that they usually know.
