Decrease of wild resources
The listed commodities of Pinellia ternata are mainly provided by wild Pinellia ternata. Due to the reclamation and utilization of barren hills and idle land in the past few years, and the extensive application of chemical fertilizers, pesticides and herbicides by farmers, its wild environment has been seriously damaged. Especially in recent years, drug farmers in Pinellia production areas have been digging and digging, and the wild resources have gradually decreased, resulting in a serious shortage of listed commodities.
Increase of pharmaceutical factory's feeding capacity
Last year, the pharmaceutical management department carried out a comprehensive rectification of pharmaceutical enterprises. After passing GMP certification, most enterprises increased the production of Chinese patent medicine decoction pieces, preparations and lotions for relieving cough and resolving phlegm, and changed Pinellia ternata into dried Pinellia ternata as raw materials, which greatly increased the market demand for dried Pinellia ternata products.
An increase in the number of exports
In recent two years, the export volume of Pinellia ternata has gradually increased. At the 36th (Zhangshu) National Medicinal Materials Fair held recently, the export orders of Pinellia ternata increased significantly compared with previous ones, and it is estimated that the export volume will reach 20 million kilograms next year.
