Selaginella officinalis comes from Shennong Materia Medica Classic. "Southern Yunnan Materia Medica" is called Huiyang grass, "Compendium of Materia Medica" calls it long-growing grass, and "classified herbal medicine" calls it Huanghuancao. "Modern practical traditional Chinese medicine" calls it the grass that revives the dead. The "Jianjiang traditional Chinese Medicine Handbook" calls it to see water and return Yang grass. So what kind of plant is Selaginella officinalis? According to the plant data of Hunan, Selaginella officinalis is a fern, its root can separate from the soil, curl up like a fist, move with the wind, meet the water and prosper, and then drill back into the soil to look for moisture. Because of its strong drought tolerance, it can stretch again as long as the root system is soaked in water after a long period of drought, so it is named. Selaginella officinalis is not only a kind of foliage plant, but also can be used as medicine. it has the effect of hemostasis and convergence, and has remarkable effect in treating hematochezia, urine bleeding, nosebleed and so on.

Pteridophyta is a large group of higher plants. At the same time, it is also a lower class of higher plants. Often a tall woody plant, it became a big forest, flourishing in the late Paleozoic era and mostly herbaceous in modern times. Ferns can be divided into five subphyla: Pteris subphylum, stone pine subphylum, leek subphylum, wedge leaf subphylum, true fern subphylum.

The leaves of general ferns have the function of producing organic nutrients by photosynthesis and producing spores for reproduction (that is, homomorphic leaves). Ferns are the oldest terrestrial plants. In the history of biological development, it has been 350 million to 270 million years from late Devonian to Carboniferous, which was the most prosperous period of ferns and was the main plant group on the earth at that time. Tall scale wood, seal wood, Reed wood and tree ferns together formed the ancient swamp forest. Since the end of Permian, a large number of pteridophytes became extinct, and their remains were buried underground, forming coal seams.

There are about 12000 species of pteridophytes, widely distributed all over the world. Most of them are native, lithophytic or epiphytic, and a few are wet or aquatic. I like a wet and warm environment.

Pteridophytes live in mountains, plains, forests, grasslands, ditches, crevices and swamps, especially in tropical and subtropical areas. There are about 2400 species in China, mainly distributed in the provinces and regions south of the Yangtze River.
