Preliminary Investigation of Resources and Medicinal Use of Codonopsis canescens
To study the resources and medicinal use of Tibetan medicine
Codonopsis canescens
,analyze its suitable habitat,and protect its wild resources,in order to provide an important reference basis for further rational development and utilization.
Method
2
Combined investigation methods of literature textual research,visiting investigation and on-the-spot investigation were adopted.
Result
2
In this paper,we investigated the resources and medicinal use of
C. canescens
in 27 cities and counties of Sichuan,Qinghai and Tibet. Compared with historical records of
C. canescens
,the results showed that there was no obvious change in the distribution range,and the distribution was uneven in different places. Ganzi Prefecture, Sichuan, boasts rich resources; in particular, Luhuo county has as high as 90-120 plants/100 m
2
, it is estimated that the reserves per unit area of root
C. canescens
in this area were 3 445.32 g·m
-2
,which totaled 1 279.18 ton(1 ton=1 000 kg). In history,the root is the main medicinal part. However, in recent years,in order to protect resources,the aboveground part is frequently used. The clinical efficacy of Tibetan medicine is mainly to tonify Qi and activate blood circulation. It can be combined with other drugs to treat rheumatism,sores,furuncle,carbuncle and other diseases. However,the plants of
Codonopsis
are mixed with
C. canescens
in each Tibetan area,and the mixed varieties are determined according to the growing varieties of the same genus in this area.
Conclusion
2
The reserves of wild resources of
C. canescens
are decreasing with the increase of clinical use and market demand of Tibetan medicine. There is serious mixture of
Codonopsis
plants in Tibetan areas. It is suggested paying attention to resource protection,carrying out artificial planting,establishing the standard for the medicinal use of Tibetan medicine,and promote rational and sustainable utilization of resources.
