Problems solved by technology

Although traditional Chinese medicine can solve local problems after sulfur fumigation, modern pharmacological research shows that long-term use of sulfur fumigated Chinese medicinal materials may cause serious harm to human liver, kidney and other organs
In addition, the residual sulfur dioxide and heavy metals in sulfur-fumigated Chinese herbal medicines have also been confirmed to have serious harm to multiple organs of the human body

Embodiment 1

[0014] Embodiment 1: the fresh Gastrodia elata after harvesting is classified according to four grades below 75g, 75-150g, 150-300g and above 300g, washed with water to remove soil and surface dirt, and steamed in a steamer for different times , less than 75g: steamed for 10min; 75g-150g: steamed for 20min; 150g-300g: steamed for 30min; above 300g: steamed for 35min. Make the moisture reach 65% at different times, take it out, cover it with a plastic film, sweat for 8 hours, take it out, flatten it, and continue to put it in the drying oven 1. 30%, put it into the drying box 2 microwave drying box, and dry it for 20 minutes with a microwave power of 19W, so that the moisture of the medicinal material is below 15%, take it out, let it cool, and it is ready.

Embodiment 2

[0015] Embodiment 2: the fresh Gastrodia elata after harvesting is divided into four grades below 75g, 75-150g, 150-300g and above 300g, washed with water to remove soil and surface dirt, and steamed in a steamer for different times , less than 75g: steamed for 10min; 75g-150g: steamed for 10min; 150g-300g: steamed for 20min; above 300g: steamed for 30min. Make the moisture reach 45% at different times, take it out, cover it with a plastic film, sweat for 14 hours, take it out, flatten it, and continue to put it in the drying oven 1. 20%, put it into the drying box 2 microwave drying box, dry it with microwave power 76W for 5 minutes, make the water content of the medicinal material below 15%, take it out, let it cool, and get it.

Embodiment 3

[0016] Embodiment 3: the fresh Gastrodia elata after harvesting is divided into four grades below 75g, 75-150g, 150-300g and above 300g, washed with water to remove soil and surface dirt, and steamed in a steamer for different times , less than 75g: steam for 8min; 75g-150g: steam for 15min; 150g-300g: steam for 25min; above 300g: steam for 32min, put in drying oven 1 electric heating constant temperature blast drying oven, and dry different grades of Gastrodia elata at 50°C Make the moisture reach 65% at different times, take it out and sweat for 8 hours, flatten it, and continue to put it in the drying oven 1 with electric heating and constant temperature blast drying. In an infrared drying oven, dry with an infrared power of 1000W for 25 minutes, so that the water content of the medicinal material is below 15%, take it out, let it cool, and obtain it.

Abstract

The invention discloses several fresh rhizoma gastrodiae drying methods, in which the rhizoma gastrodiae is put into one or sequentially two or more different equipment to be dried. In a complex drying method, the rhizoma gastrodiae is put into equipment for easily removing moisture on the surface of the rhizoma gastrodiae first and then is put into equipment for easily removing moisture inside the rhizoma gastrodiae, so that active components in the rhizoma gastrodiae can be prevented from being destroyed, and the moisture content of the rhizoma gastrodiae can quickly reach a standard required in Chinese Pharmacopoeia; harm caused by sulfur fumigation in the processing process is avoided; through content comparison and efficacy comparison among five active components in the rhizoma gastrodiae in different processing groups, an optimal processing method is selected, and the accuracy and reliability of the method can be reflected better.

Description

technical field [0001] The invention relates to a processing method of a traditional Chinese medicine, in particular to a processing method of the traditional Chinese medicine Gastrodia elata. Background technique [0002] Rhizoma Gastrodia (Rhizoma Gastrodia), formerly known as Chijian, is the dry tuber of Gastrodia elata Bl., a traditional Chinese medicine in my country. Expelling wind to relieve spasm, calming liver-yang, dispelling wind and dredging collaterals. For convulsions in children, epileptic convulsions, tetanus embolism. Mainly produced in Guizhou, Sichuan, Yunnan, Hubei, Shaanxi and other places. Fresh Gastrodia elata medicinal materials have a high water content, with a dry-to-dry ratio of about 5.5:1, and contain a lot of polysaccharides, mucus, and are not easy to dry. At present, the processing methods of Gastrodia elata are generally sun-dried, smoked, and dried by fire. The processing time is long and the operation is cumbersome, which not only makes ...
