You can suck sulfur. Ginger with mud can be smoked with sulfur, because sulfur is a neutral chemical substance, which can remove microorganisms and harmful substances on the surface of ginger during smoking, thus prolonging its storage time. At the same time, the surface of the smoked ginger is smooth and clean, which looks better. In the process of smoking, the sulfur in ginger will react with water and organic matter to produce smoke. These flue gases contain harmful substances such as sulfur dioxide, and long-term inhalation may have a certain impact on human health. Therefore, pay attention to ventilation when smoking to avoid inhaling harmful substances.
