Afterwards, Heshan Workers’ Hospital and the relevant medical and health units in the region formed a research collaboration group to conduct further research on Huang Genyi’s drug. In the past few years, more than 1,000 rats were divided into more than one hundred experimental groups for the treatment of silicosis models. Observations further confirmed the therapeutic effect of Huanggen. At the same time as animal experiments, Heshan Workers’ Sanatorium was treated with Huanggen decoction for clinical observation. Generally, the response was good, symptoms were relieved, and the physical strength was enhanced. X-ray photographs showed that most of the disease stabilized after four years of observation and comparison.
