Traditional Chinese Medicine believes that dampness is a pathogenic factor in yin, which can easily damage yang qi and obstruct qi mechanisms. Its illness is lingering and difficult to cure.
Moisture can dissipate phlegm and cause blockages in the air system, just like walking in mud during heavy rain.
中医学认为，湿为阴邪，易伤阳气，易阻气机，其病缠绵难愈。
湿气化痰淤，就会导致气机不通，就像大雨中，在淤泥中行走一般。
