How to evaluate scorpions in the Compendium of Materia Medica 5

According to the "Compendium of Materia Medica" and the "Chinese Pharmacopoeia", the whole scorpion has the functions of "extinguishing wind and antispasmodic, anti-inflammatory and attacking poison, and relieving pain"; It is mainly used for the treatment of "pediatric convulsions, convulsions, ** diseases, cardiovascular and cerebrovascular diseases, inflammation, hepatitis B, tumors" and other diseases.

The ** of the plant kingdom scorpion grass is very advanced, it is a nettle family that grows in relatively humid and shady places.

Scorpion grass also has thorns, but its stings are very special, the stings are hollow, there is a kind of venom in it, if a person or animal touches it, the spine will automatically break, and inject the venom into the human or animal's **, which will cause **inflammation or itching. In this way, wild animals do not dare to encroach on them.

Toxic substances in plants are the most powerful defenses in the plant world**. Agave contains a steroid that causes the red blood cells in an animal's body to rupture and die.

Oleander contains a muscle relaxant, not to mention insects and birds eat it, even people and animals can not save their lives. Poison hemlock is a plant in the Apiaceae family, and its seeds contain alkaloids, and animals die within hours of eating. In addition, the young leaves of aconitum and the young leaves of quinoa are also very toxic, and if cattle and sheep eat them, they will also be poisoned and die.

The whole body of croton is poisonous, and the crotonin contained in its seeds is even more toxic, and animals will vomit, diarrhea, and even shock after eating.

There is a toxin in potatoes that can kill leafhoppers when they bite into it. Although some plants also contain alkaloids, they just taste bad, and herbivores who have tasted bitterness do not dare to eat it anymore. They use a mildly powerful chemical** that is purely defensive in nature.

To ward off attacks from germs, insects, and birds, some plants grow all sorts of wonderful organs, just like our human armor. Tomatoes and apples, for example, use thickening the cuticle to resist bacteria. A layer of wax grows on the surface of wheat leaves, and rust bacteria cannot harm it.

The "armor" of insect-resistant corn is more advanced, and its bracts can tightly wrap around the ears of fruit, keeping pests inside, allowing them to kill each other, eat the weak, or drive pests to the filaments and let them poison themselves.
