The Efficacy and Functions of Codonopsis (Dang Shen)

Codonopsis, also known as Dang Shen (党参), Lu Dang Shen (潞党参), and Fang Dang Shen (防党参), is a commonly used Qi-tonifying herb in Traditional Chinese Medicine (TCM). It belongs to the Campanulaceae family and is a perennial herbaceous plant with milky sap. The stem base has multiple tuberous stem scars, and the root is often large, spindle-shaped or spindle-shaped cylindrical, with few branches or slightly branched below the middle, measuring 15-30 cm in length and 1-3 cm in diameter. The surface is grayish-yellow, with fine ring patterns on the upper part measuring 5-10 cm. It is found in the mountainous forest edges and shrubs of northern China at altitudes of 1560-3100 meters. In ancient times, due to the scarcity and high price of ginseng, many people began to use Codonopsis as a substitute for ginseng as early as the Han Dynasty. It is mainly produced in Shanxi, Shaanxi, and Gansu, with the best quality coming from the Shangdang region of Shanxi. According to “Bencao Congxin” (本草从新), Codonopsis tonifies the middle and benefits Qi, harmonizes the spleen and stomach, and alleviates thirst. Let’s explore the efficacy and functions of Codonopsis, as well as its dietary recommendations and contraindications!

The Efficacy and Functions of Codonopsis (Dang Shen)

01

The Efficacy and Functions of Codonopsis

The first function is to tonify the middle and benefit Qi, as well as to generate fluids and alleviate thirst. It primarily has a strong Qi-tonifying effect on the upper and middle Jiao (regions), especially for patients with spleen Qi deficiency, which can lead to symptoms such as reduced appetite, abdominal distension, and diarrhea.

For patients with lung Qi deficiency, which can cause cough, scanty phlegm, and shortness of breath, Codonopsis is also effective.

The third function is for conditions such as organ prolapse caused by spleen Qi deficiency, including gastric prolapse and uterine prolapse. Codonopsis is commonly used for these conditions due to its Qi-tonifying properties.

Fourthly, it has a fluid-generating effect. It does not merely lead to significant thirst after tonifying the kidneys; rather, it generates fluids, making it useful for conditions of thirst and fluid deficiency caused by heat or diseases. Modern medicine recognizes that Codonopsis has a broad range of effects, primarily enhancing the body’s immune function and increasing the ability to resist diseases through immune regulation.

Dietary Recommendations and Contraindications for Codonopsis

Usage Recommendations

It is suitable for individuals with Qi deficiency and Yang deficiency. It should be avoided in cases of excess conditions or heat conditions. It is not advisable to use it alone in cases of Zheng deficiency and Xie excess. When taking Codonopsis, it is advised to avoid drinking tea. It should not be used in conjunction with Li Lu (藜芦). It can assist in general deficiency conditions and can replace ginseng; however, in cases of severe deficiency, ginseng is preferred.

Properties and Meridians

It is neutral in nature, sweet in flavor, and enters the spleen and lung meridians.

How to Select

Choose roots that are large, with many stripes and firm texture. The root tops should be rounded, commonly referred to as “lion’s head”.

Tea Preparation

Combine 10 grams of Codonopsis and roasted Astragalus (Huang Qi, 黄芪), 5 grams of Bai Zhu (白术), and 10 jujubes (Da Zao, 大枣), and decoct in water to drink as tea. This tea has immune-boosting effects.
