Baota sugar is born with the times.
Ascaris is what we now call a parasite. It is a kind of worm with pink body surface, horizontal stripes on the body surface and curly tail in the male. At that time, the economic level of China was still at a backward level, and the living standard of the domestic people was generally low. The rice given to children every day is absorbed by ascaris before the nutrition is absorbed by children. In the long run, the child's physical immunity has declined in all aspects. In order to let children eat pesticides, candy was melted into medicine, so this kind of Baota candy came into being.
The main raw material of Baota sugar is basket.
Penny is a good herb to kill parasites. Generally planted in winter or spring, the flowering and fruiting time is between August and June 5438+00. This herb is extremely cold and should be dried quickly after picking. At that time, there were no baskets in China, and the baskets for making Baota sugar were basically imported from the Soviet Union. However, after the 1960s, Sino-Soviet relations deteriorated, and the Soviet Union tore up the aid contract and withdrew the raw materials for extracting baskets. At the same time, the planting area of Zizania latifolia is expanding, but there is no effective extraction method, which leads to many Zizania latifolia rotting underground.
Baota sugar withdrew from the historical stage.
By 1982, researchers in China have made continuous efforts and finally developed a new pesticide that can replace Baota sugar. The major pharmaceutical companies finally stopped planting and producing bamboo baskets. At this point, Baota sugar, which is popular all over the country, has become a legend and remained in the memory of the previous generation.
