There were many types of antibiotics, such as penicillin, tetracycline, and erythromycin. With the conditions in Xiuzhuzhou, it was impossible to make them.
Or to be precise, they could be produced but not purified.
Using penicillin as an example, there was a large amount of harmful substances in the mold culture. Using it without purification was no different from suicide.
Moreover, the output of mold culture that did not go through industrial selection was devastatingly low.
However, it was different for allicin. Garlic cloves yield about 2.5 milligrams of allicin per gram of raw weight, and the harmful substances were much fewer as well, so the extraction of allicin could be done in Xiuzhuzhou.
