Specific techniques known as Saiseihigen are reported as a measure for Mine Worker's Disease at the Iwami-Ginzan Silver Mine (Omori-cho, Oda City, Shimane). One was to boil four kinds of medicinal herbs with vinegar and water, and to send the medicine in the form of steam into the tunnel during ventilation. The other was to use have the workers use a mask, Fukumen, which included sandwiching plum meat in the mask. As a result, it is reported that both the air that was ventilated became fresher and dust suppression were realized. Neither the aim nor the assumed effect of the application of steam medicine, the main subject, were mentioned in a classical book on herbs, so inference was used. For dust suppression, it was argued that moisturization using steam and acid steam acted as a dust suppression agent. The author argues that the effects of countermeasures against dust prevention, which are carried out today, such as humidification and the use of dust suppression agents, were obtained. It is noteworthy that implementation of countermeasures resulted in a foreseeable effect.
