Caulis Cistanchis is a precious traditional Chinese medicine in China. It has been used as a tribute to the western regions in history.
For many years, Caulis Cistanchis has only been used as medicinal materials and health products; However, since january2020, all provinces and regions in China have successively issued the pilot scheme for nine food and drug substances, and the business circles in Inner Mongolia and Xinjiang pay more attention to Caulis Cistanchis.
01 magical plant -- Caulis Cistanchis
Caulis Cistanchis is parasitic on the roots of desert plants. This plant is Haloxylon ammodendron, a kind of sand fixing and afforestation plant. Haloxylon ammodendron is the first tree species in the "ant forest" and the most common tree species for greening the desert. A Haloxylon ammodendron can fix 10 square meters of desert, which is called "the king of desert vegetation". Caulis Cistanchis parasitic on the roots of Haloxylon ammodendron is also called desert Caulis Cistanchis.
Caulis Cistanchis is a perennial parasitic herb of the family orobanaceae. There are two main species, Caulis Cistanchis and Cistanche tubulosa. It is mainly distributed in Alxa, Hotan and other regions in western Inner Mongolia. Its edible part is a dry fleshy stem with scaly leaves, which is called "desert ginseng".
Caulis Cistanchis can be harvested in spring and autumn, but the quality of harvest and excavation in autumn is better. Spring is the main harvest and excavation period, but seeds can be kept. After growing on the ground, Caulis Cistanchis will soon blossom and seed, and its nutritional value will be relatively reduced. However, its seeds will spread by using external forces such as wind, and a large number of seeds will fall into the sand. Once the seeds feel the chemical substances and nutrients released by the host plants, they will start germination and parasitic growth, which is the growth process of wild Caulis Cistanchis.
02 what is the difference between deserticola deserticola and Cistanche tubulosa
The flora of China includes Caulis Cistanchis, Caulis Cistanchis, Cistanche tubulosa, and Cistanche halophila. The common Caulis Cistanchis and Cistanche tubulosa also have great differences.
First, the host is different.
Desert Caulis Cistanchis is parasitic on the roots of Haloxylon ammodendron and Haloxylon ammodendron in Chenopodiaceae. Cistanche tubulosa is parasitic on the roots of Tamarix or Salix
Secondly, the geographical distribution is different.
Caulis Cistanchis can not grow independently. It must attach to the root of the host plant to obtain nutrients and water. Therefore, the geographical distribution of Caulis Cistanchis coincides with that of its host plants.
Desert Caulis Cistanchis is mainly distributed in Alxa Left Banner, Ejina Banner and wulathou banner in central and Western Inner Mongolia, Zhangye and Wuwei in Gansu, Northern Xinjiang and Qinghai.
Cistanche tubulosa is mainly distributed in southern Xinjiang around Taklimakan Desert, such as Hotan and Bazhou. The yield of Cistanche tubulosa in Hotan is the largest and the quality is better.
Third, the growth cycle is different.
Caulis Cistanchis is a perennial plant. As long as it does not grow above the ground, it will continue to grow. Caulis Cistanchis has a longer growth cycle than Cistanche tubulosa.
Fourth, different applications
At present, both can be used in medicine and health food. In the future, Caulis Cistanchis may be used in the field of common food.
However, due to its short growth cycle and high yield, Cistanche tubulosa is intensively planted in Xinjiang and other places with low cost. At present, Cistanche tubulosa is widely used in Chinese patent medicine.
