A few years later, Kang Boqing, who is skilled in pharmaceutical technology and familiar with the efficacy of medicinal materials, left the pharmacy where he worked and began to make various Chinese medicines at home, such as Qizhen Dan, Heihu Dan, eye patch, Wanying Ingot and small plaster.
At that time, he cooked drugs during the day and walked around the street with his bag on his back at night. Kang Boqing understands that it is difficult for his homemade drugs to compete with those of big pharmacies in big cities, but because these drugs do have curative effects, they have a broad market in the vast rural areas, especially in remote mountainous areas. As a result, he often goes to towns and villages far and near to serve rural villagers, and sometimes he sells medicine to small vendors in other places. These practices are generally welcomed by rural residents who lack medical care and medicine. At that time, life in the countryside was poor, people's diet was poor, and it was easy to get angry. Hei Hu Pill made by Kang Boqing has the effects of purging heat and clearing the stomach, and is very effective in resolving food stagnation, which is deeply loved by villagers. Another Chinese medicine he made blindly, Qizhen Dan, is mainly used to treat children's acute fever, convulsions, convulsions and constipation, which often has miraculous effects and is trusted by villagers.
Because these drugs are cheap, easy to take and effective, they quickly opened the market and gained some fame. Kang Boqing is full of confidence, determined to develop new drugs and embark on a unique road of his own. 192 1 year, he bought a house in the south gate of Chongwenmen with the money accumulated from selling medicines and opened a Deshoutang drugstore himself. Kang Boqing hired Wu Hongxi, an experienced old Chinese doctor, to be a doctor in the pharmacy. With the assistance of Wu Hongxi, Kang's secret Niuhuang Jiedu Pill and Niuhuang Qingxin Pill were successfully developed to clear away heat and toxic materials, dispel wind and relieve pain. Because the pills are prepared with honey and sealed with wax skin, they can be hidden for a long time.
After Deshoutang produced and sold Niuhuang Jiedu Pills, patients enthusiastically bought them. Because of the remarkable curative effect of the drug and the introduction of patients to each other, Niuhuang Jiedu Pill suddenly became famous.
When Deshoutang was founded, it was just a small pharmacy dealing in pills, powder and pills, and rented four rooms for grinding. After relying on the best-selling Niuhuang Jiedu Pill to accumulate funds, pharmacies entered a period of rapid development.
1928, Kang Boqing bought more than 10 houses in Huashi East Street and opened Deshoutang East. The pharmacy originally opened in Nanxiaoshikou was changed to the general number. The general number extends to both sides of the pavement, and there are more than 20 shops in * * *.
In addition to some medicines such as Niuhuang Jiedu Pills sold in Beijing, Deshoutang is mainly sold to other places and vast rural areas. There are agents in Shandong, Shanxi, Henan, Shaanxi, Sichuan and other places, and the drugs are sent to Shanghai, Tianjin, xi, Guangzhou, Chengdu, Changchun, Shenyang and other big cities through wholesalers. Due to the large demand, customers will remit the order first, and Deshoutang will deliver the goods. Both sides pay great attention to credibility. During 10, Deshoutang became a powerful and famous pharmacy in Beijing.
Kang Boqing advocates innovation and enterprising, abandons conservatism, and is good at learning from the strengths of various schools and creating his own new path. He believes that people need to invent and innovate all their lives, and all successful new drugs are improved and perfected on the basis of ancient prescriptions. At that time, Deshoutang innovatively developed more than 200 kinds of pills according to the formula of 1000 formulated by Shi Jing Chinese Medicine Chamber of Commerce. Besides the Niuhuang Jiedu Pill made by Kang, there are Niuhuang Qingxin Pill, Shugan Pill, Huachong Powder, Mao Jie Pill, Xiling Pill and Xiaoer Zhike Pill, which are also very popular with patients.
In order to maintain the reputation of Deshoutang, Kang Boqing is very strict about the quality of drugs and is very particular about the selection of materials. Any unqualified material would rather be discarded than used. For example, Scutellaria baicalensis Georgi is mostly selected from Rehe Chengde, rhubarb is purchased from Xining, realgar is mostly Su Realgar, and yam must be pruned in Henan. The prescription attached to the pill and sold together explains in detail what diseases should be dissolved, chewed and swallowed, decocted and taken, and externally applied to the affected area. In order to make the drug exert the best curative effect and eliminate the side effects caused by improper medication.
1937 After the July 7th Incident, the Japanese army occupied North China, traffic was blocked, prices soared, and Deshoutang was also hit hard. The raw materials of pharmacies are extremely scarce, and the production and sales of drugs have dropped sharply.
It was not until 1949 that Beiping was liberated that the fate of Deshoutang took a turn for the better. Since then, Deshoutang has handed over the secret recipe of Niuhuang Jiedu Pill to the state, and made it into medicine and decoction to continue to contribute to relieving people's pain.
