The function and difference between Artemisia and Artemisia

Artemisia argyi and Artemisia are similar, and they may not be able to tell the difference between them in the wild. So what are the functions and differences between Artemisia and Artemisia?

I. the difference between Artemisia and Artemisia

Artemisia leaf and Artemisia grass belong to the Compositae plant, the scientific name of Artemisia annua is Artemisia annua, and the scientific name of Artemisia argyi is Artemisia argyi, the similarity of the name is easy to misunderstand. They often grow in places where soil moisture is rich, such as ridges and ponds. And the growth cycle of Artemisia argyi leaves is long, starting from March, can grow to May, but Artemisia grass past Ching Ming Festival (about April), also passed the most tender time.

The height of Artemisia grass is lower, the trunk is also relatively small, the stem is dark red, the best growth of Artemisia grass, only about 10 cm. But the moxa leaf is different, its trunk is slightly thick and long, the stem is light green, the root near the ground is slightly Lignified (hard), some can reach 1.5 cm in diameter and 80-250 cm in height.

Artemisia leaves are usually thin, the front color is white, there will be a layer of white villi, soft and smooth, the leaves are small, the serrated lines around them are deep, and the whole leaves are long and narrow. On the other hand, the surface of Artemisia argyi leaves is gray-green, white villi on the back, the leaves look fat, the leaves are wider than Artemisia grass, the serrated around the leaves are much smaller, and the back is densely covered with gray-white spider silk villi.

Another way to tell the difference is smell, but because both plants have fragrance, it is more difficult to distinguish them unless they are particularly experienced. The aroma of Artemisia grass is faint, and some even have a slight smell of grass. On the other hand, the taste of moxa leaves is slightly spicy and cool oil, which belongs to the "heavy taste". In addition, the stem of Ai is relatively soft, while Artemisia annua is brittle and easy to break.

Second, the role of Artemisia grass and moxa

1. The function of Ai: the whole grass is used in medicine, which has the effects of warming menstruation, removing dampness, dispelling cold, stopping bleeding, anti-inflammation, relieving asthma, relieving cough, calming the fetus, anti-allergy and so on. The whole grass is used as insecticidal pesticide or fumigation as room disinfection and insecticide. Moxa dried and crushed into Artemisia powder, which is a high-quality feed additive for livestock and poultry. It can also be used as a natural plant dye. Buds and seedlings are used as vegetables.

two。 The role of Artemisia grass: many species are used in medicine for important or commonly used anti-inflammation, hemostasis, warming menstruation, relieving surface, antimalarial and cholagogic drugs or moxibustion; a few species are used for food; many species distributed in grasslands and meadows are used as livestock feed Some shrubs or semi-shrubs growing in desert or semi-desert areas have thick and deep roots, strong tillering ability of stems and branches, tolerance to drought and salinity, and are used as pioneer plants for windbreak and sand fixation or as auxiliary plants.

Although the two look very similar, but the function is not the same, so we must carefully distinguish, so as not to confuse.
