There are many authentic medicinal materials in Zhejiang, but "Zhejiang Eight Flavors" is the most famous. "Eight flavors of Zhejiang" actually refers to eight Chinese herbal medicines, namely Atractylodes macrocephala, Radix Paeoniae Alba, Fritillaria thunbergii, Chrysanthemum morifolium, Rhizoma Corydalis, Radix Scrophulariae, Radix Ophiopogonis and Radix Curcumae, which have been highly praised by doctors in past dynasties for their good quality, wide application range and good curative effect. As early as in Treatise on Febrile Diseases by Zhang Zhongjing, a famous doctor in Han Dynasty, there were 58 applications of "Zhejiang Eight Flavors". Li Shizhen, a famous pharmacist in the Ming Dynasty, quoted the illustrated Materia Medica in the Song Dynasty in the Compendium of Materia Medica, saying: "Atractylodes macrocephala was born in Hangzhou and Vietnam." It can be seen that "Zhejiang Eight Flavors" has long been famous at home and abroad. Some famous old pharmacies, such as Beijing Tongrentang, Shanghai Leiyunshang and Hangzhou Huqingyutang, all choose "Zhejiang Eight Flavors" as the formula. "Zhejiang Eight Flavors" has a long history of cultivation in Zhejiang.
According to statistics, from 65438 to 0996, Corydalis yanhusuo planted 27,000 mu in Zhejiang with a yield of 2.7 million Jin, accounting for about 80% of the national total output. Atractylodes macrocephala planted 4,200 mu, with an output of 4.72 million kg, accounting for about 40% of the country. However, because there is no Chinese herbal medicine market in Zhejiang, and there is a lack of purchasing, selling and circulation links, the output of Zhejiang "Zhejiang Eight Flavors" fluctuates greatly, which greatly blows the enthusiasm of drug farmers. Take Fritillaria thunbergii as an example. In 1950s and 1960s, the supply of Fritillaria thunbergii was in short supply for a long time. In 1970s, Zhejiang producing areas, with the support of national medicinal materials companies, took various measures to control commodity fields and develop Dantian. After more than ten years of hard work, they have spent a lot of manpower, financial resources and material resources. By the mid-1980s, the volume of commodities reached 450-500 tons, which could meet the national demand. Since the 1990s, due to the poor sales of medicinal materials, the enthusiasm of drug farmers has decreased. In the 1970s, some new producing areas (Yuyao, Fenghua, Zhoushan) and old producing areas (Xiangshan, Yinxian) have sold seeds as commodities, and the number of fields alone has decreased by thousands of acres. The consequences of this "killing the goose that lays the golden eggs" are unimaginable, and the Fritillaria thunbergii base, which has been supported by the state for more than ten years, also exists in name only. Another example is Scrophularia. In 1960s, the planting area of the whole province was 7445 mu, and the output was1.2500 kg. However, in the 1990s, for the same reason, the enthusiasm of drug farmers was greatly reduced, and the output was always at a low level. Pan 'an County, the main producing area, has an annual inventory of about 100 tons. In the past, the output of Ophiopogon japonicus was between 200 and 250 tons per year, and it could be exported. However, the output has been greatly reduced in recent years, and the output of 1996 is only 50 tons, which is incomparable with the past. 1997 The planting area of Chrysanthemum morifolium is about 40,000 mu, the output is 3,200 tons, and the estimated income is 76 million yuan. However, because there is no direct trading place in Zhejiang, it needs to be transported to other places, which leads to the decline of quality and income during transportation170,000 yuan. In addition, foreign drug dealers often pretend to be Ophiopogon japonicus in order to make huge profits, which has brought extremely adverse effects on the reputation and development of "Zhejiang Eight Flavors" for a long time. Therefore, it is necessary to establish Zhejiang Chinese herbal medicine circulation market as soon as possible.
In recent years, Zhejiang is intensifying and deepening the research on "Zhejiang Eight Flavors", and applying high technology, especially biotechnology and cell engineering, has achieved success in accelerating the propagation and improving the efficacy of "Zhejiang Eight Flavors" such as Fritillaria thunbergii. Recently, Xinchang Pharmaceutical Factory of Zhejiang Pharmaceutical Co., Ltd. has begun to study the extraction and preparation technology of fat-soluble effective components of Atractylodes macrocephala. I believe that in the near future, "Zhejiang Eight Flavors" will glow with more brilliant brilliance.
