Writer: Hongji MedicalHongji Medical

Astragali Radix, also known as Huang qi, is a medicinal material with a long history. Its medicinal history can be traced back to before the Han Dynasty. It was first recorded in the "Shennong Bencao Jing" and was listed as a top-grade product. The scientific name of Astragalus is Astragali Radix, which mainly comes from the dried roots of the leguminous plants Astragalus mongolica and Astragalus membranaceus . The main producing areas include Inner Mongolia, Shanxi, Hebei and other places.


In the Shennong Bencaojing, Astragalus is described as " sweet in taste, slightly warm; used to treat carbuncle, long-term wounds, pus discharge and pain relief, severe wind, dysentery, hemorrhoids, fistula, tonic, and all kinds of children's diseases ". In the Qing Dynasty, Wang Ang's "Compendium of Materia Medica" believed that Astragalus " can be used raw to strengthen the exterior, roasted to nourish the middle and replenish the vital energy ". Li Shizhen mentioned in the "Compendium of Materia Medica": "Qi means long, and Astragalus is yellow in color, which is the best tonic, hence the name." The records in these ancient books fully affirm the important position of Astragalus in traditional Chinese medicine.

Astragali membranaceus is the dried root of Astragalus polysaccharides, while Astragalus membranaceus is the dried root of Astragalus mongolicus or Astragalus membranaceus. Although Astragalus membranaceus and Astragalus membranaceus have similar names, they are actually two different medicinal materials. There are obvious differences in appearance between the two: Astragalus membranaceus has a light brown or light brown surface with irregular longitudinal wrinkles or longitudinal grooves; Astragalus membranaceus has a gray-red-brown surface with longitudinal wrinkles, transverse lenticel-like protrusions and a few root scars. The outer skin is easy to fall off, and the peeled part is light yellow.

Roasted Astragalus is milder in nature and flavor than raw Astragalus, and its main effects are to replenish qi and moisten the lungs, strengthen the spleen and harmonize the stomach . Roasted Astragalus is often used for symptoms such as weak spleen and stomach, poor appetite and loose stools, sinking of middle qi, and long-term diarrhea and prolapse of the anus. It is particularly suitable for situations where it is necessary to replenish the middle qi . Roasted Astragalus has a stronger effect of replenishing qi and has a certain effect of moistening the lungs.

The storage of Astragalus also requires attention. To prevent moisture and insect infestation, Astragalus should be stored in a dry, cool place or refrigerated in the refrigerator, and be especially careful not to expose it to sunlight for a long time .


Pressed tablets, round tablets, and nail-shaped tablets: Different ways to cut Astragalus


The following are all tragali, but they are cut in different ways, so they look like completely different herbs. Due to the different origins of tragali, the skin of tragali may appear yellow or black. Traditionally, it is believed that the black skin is more effective, and it is also called "black tragali".

Long strips: This is the most common shape of tragali in Hong Kong. Because it looks like an arrow, it is also called arrow tragali. The original plant of tragali is like a branch. Long strips of tragali are cut straight and then flattened by a machine. In the industry, it is called "pressed slices" or "longitudinal slices".


Grains: This is the common cutting method in the Mainland. Tragali is cut into grains directly. It is easier to handle. This is a flat-cut "round slice". Now in Hong Kong, many tragali are sold in this shape.


Slices: This is also the common cutting method in mainland China. Slanting cuts become "nail-shaped slices", making the tragali look a little thicker.
