Distinguishing Between Artificial Cultivation And Wild Of Cistanche Deserticola

Overview of Cistanche deserticola
Cistanche deserticola is known as the "desert ginseng" and has rich nutritional and medicinal value. Mainly grows in deserts and desert areas, preferring warm, dry climates and sandy soils.
Cistanche deserticola is a fleshy stem of the Cistanche genus in the family Liliaceae, characterized by dried and scaled leaves. It is also known as the Big Cloud, Cistanche deserticola, goblin, and golden bamboo shoots. As an extremely precious traditional Chinese medicine, it has been regarded as a precious tribute to the imperial court by various countries in the Western Regions throughout history. It is sweet and warm in nature, salty and moist in texture, with the functions of nourishing yang without dryness, warming and promoting kidney yang, and tonifying kidney deficiency; The characteristics of nourishing yin without greasiness, moistening the intestines and promoting abdominal circulation to treat constipation.

Cistanche deserticola is a parasitic plant that parasitizes the roots of the desert plant Haloxylon ammodendron, with low requirements for soil and water. It mainly grows in the Gobi Desert environment with extreme drought climate, strong sunshine, annual precipitation less than 250mm, severe changes in temperature, strong winds and sand, poor soil development, medium fine sand, thin soil layer with coarse texture, neutral or slightly alkaline, high salt content and lack of organic matter. Seeds are abundant, small and light, and have a longer lifespan.
Its morphological characteristics are perennial parasitic herbs, with a height of 40-160cm. The stem is fleshy, with a single or basal part consisting of 2 or 3 branches. The lower part is 5-15cm wide, and the upper part gradually becomes thinner, with a width of 2-5cm. Leaves numerous, scaly, arranged in a spiral pattern, pale yellow white, without petioles. Spike inflorescence, 15-50cm long; The flower is yellow white, light purple, and turns brown after drying. There are two vertical bright yellow protrusions inside the tube. Capsule ovate, 2-lobed, brown. The seeds are mostly small, oval shaped, with a network like surface and a glossy appearance. The flowering period is from May to June, and the fruiting period is from June to July.

Growth and reproduction are mainly achieved through seed propagation, and can be selected from sandy or semi sandy desert areas. It is suitable for parasitic growth of Haloxylon ammodendron and utilizes deserts with concentrated natural Haloxylon ammodendron forests. Or cultivate artificial Haloxylon ammodendron forests, dig seedbeds about 50-80cm east or southeast of the forest, sow seeds in holes on the seedbeds, apply camel manure, cow and sheep manure, cover with soil, and leave ditches or seedbed pits on top for watering. After sowing, keep the seedbed moist and induce the host roots to extend onto the seedbed. Sow in spring and autumn, and within 2 years, some beds will be parasitized by Cistanche deserticola. A few will be unearthed and grow, while the majority will be unearthed within 2-4 years, flowering and fruiting. At the same time, due to the strong winds in the desert, it is important to cultivate soil or wrap branches around the exposed host roots to prevent wind damage. The seedbed should be regularly watered to maintain moisture and other plants should be removed. When Cistanche blooms in May, artificial pollination is necessary to increase the fruiting rate.
The lower classification of Cistanche deserticola includes Cistanche deserticola and Cistanche deserticola. Cistanche deserticola has yellow brown leaves and stems, purple brown flowers, and stems that can be used as medicine and food. Its main host plants include sand protecting plants such as Haloxylon ammodendron, Tamarix genus, and Salicornia genus.
Cistanche deserticola has extremely high medicinal value, as discussed in Li Shizhen's "Compendium of Materia Medica" during the Ming Dynasty. It can be used for conditions such as labor injury, kidney deficiency, white turbidity, excessive sweating, constipation, easy hunger during digestion, and tetanus. It is also recorded in the Dictionary of Traditional Chinese Medicine, and its aliases include Rou Song Rong, Zong Rong, Di Jing, Jin Sun, Da Yun, etc. Harvesting can be done in both spring and autumn, preferably between March and May.
In recent years, breakthrough progress has been made in simulating wild planting of Cistanche deserticola on sandy riverbanks in the Cangzhou area of Hebei Province, as the soil quality is much better than in desert areas and the resulting Cistanche deserticola has extremely high quality.

The difference between artificial cultivation and wild cultivation
(1) Quality
Wild Cistanche deserticola grows in natural environments and is greatly influenced by natural factors, resulting in unstable quality. Due to the uncontrollable growth environment, wild Cistanche deserticola may be contaminated by the surrounding environment, resulting in safety issues such as excessive heavy metals. For example, in some polluted deserts and desert areas, wild Cistanche deserticola may absorb harmful substances from the soil, thereby affecting its quality.
Artificially planted Cistanche deserticola uses scientific planting techniques, selects high-quality seeds and suitable soil, and has stable quality. During the planting process, growers will test and improve the soil to ensure that it meets the growth needs of Cistanche deserticola. Meanwhile, selecting high-quality seeds can ensure the genetic quality of Cistanche deserticola. And through scientific management and strict testing, safety and environmental protection are guaranteed. During the planting process, pest and disease control measures will be taken on Cistanche deserticola to avoid the use of highly toxic pesticides and ensure the safety of the product. At the same time, monitor the planting environment to ensure that Cistanche deserticola grows in a pollution-free environment.

(2) Production volume
Wild Cistanche deserticola is rare in quantity, difficult to harvest, and has a low yield. Wild Cistanche deserticola grows in remote areas such as deserts, and its distribution is relatively scattered. Finding and harvesting it requires a lot of manpower and time. Moreover, excessive harvesting can cause damage to the ecological environment of wild Cistanche deserticola, further reducing its yield.
Artificially planted Cistanche deserticola has a high yield through large-scale cultivation and scientific harvesting methods. Artificial planting can select suitable land for large-scale cultivation, and increase the yield of Cistanche deserticola through reasonable planting density and management measures. Meanwhile, scientific harvesting can avoid excessive damage to Cistanche deserticola plants and ensure their sustainable growth.
(3) Price
Wild Cistanche deserticola is expensive due to its scarcity, difficulty in harvesting, and unstable quality. Due to the scarcity of wild Cistanche deserticola, the market is in short supply and the price is naturally higher. Moreover, harvesting wild Cistanche requires professional personnel and equipment, and the cost is also relatively high. In addition, the unstable quality also causes significant price fluctuations in wild Cistanche deserticola.
The cost of artificially cultivated Cistanche deserticola is relatively low, but the price is also relatively high due to market supply and demand. Artificially planted Cistanche deserticola can reduce costs through large-scale production, but it also requires certain human, material, and financial resources to be invested in the planting process. However, due to its stable quality, high output, and relatively low price, it is increasingly favored by the market. With the continuous improvement of people's understanding of Cistanche deserticola, the demand for artificially cultivated Cistanche deserticola in the market is also increasing, and the price will be affected by the market supply and demand relationship.
How to distinguish?
(1) Appearance
Wild Cistanche deserticola has a darker color, appearing dark brown or black, with small scale like textures on its surface. Its size and shape vary depending on factors such as growth environment and harvesting time. Wild Cistanche deserticola grows naturally in harsh environments, such as Qinghai, Gansu, Ningxia, and other areas in northwest China, where the climate is dry and cold, and the soil is poor. These special growth environments make the color of wild Cistanche deserticola darker and the surface texture more distinct. Due to uncontrollable growth conditions, their sizes and shapes also vary.
Artificially planted Cistanche deserticola has a lighter color, appearing light brown or yellow brown, with a smoother surface and relatively uniform specifications and shapes. Artificially cultivated Cistanche deserticola is usually grown in greenhouses or greenhouses, where growers choose suitable soil and climate conditions and use scientific planting techniques to cultivate Cistanche deserticola. Therefore, its growth environment is relatively stable, the color is light, the surface is smooth, and the specifications and shapes are relatively uniform.

(2) Odor
Wild Cistanche has a faint fragrance. Wild Cistanche deserticola grows in natural environments and is not contaminated by fertilizers or pesticides, so it has a faint fragrance.
Artificially cultivated Cistanche deserticola may have the odor of fertilizers or pesticides, but the odor may vary among different regions and varieties, and odor is not an absolute judgment criterion. Artificially planted Cistanche deserticola may use fertilizers or pesticides during the planting process, so it may have some odor. However, the odor of Cistanche deserticola from different regions and varieties may also vary, so odor cannot be used as an absolute criterion for judgment.
(3) Taste
Wild Cistanche deserticola has a rich taste and strong medicinal effects, and should be consumed in moderation. Due to its harsh growth environment, wild Cistanche deserticola is more nutritious and has a better taste. However, due to its strong medicinal properties, it needs to be consumed in moderation.
Artificially cultivated Cistanche deserticola has a lighter taste and relatively weaker medicinal effects. Artificially planted Cistanche deserticola is subject to artificial intervention during its growth process, resulting in relatively low nutritional content, weak taste, and relatively weak medicinal effects.
