What is the evil qi that often traps the spleen first after causing illness?

The evil that often traps the spleen first after causing disease is dampness.
Dampness is divided into external and internal dampness. External dampness is mostly caused by exogenous factors, such as living in wetlands for a long time and getting wet in the rain. Internal dampness is generally generated by the body itself, such as spleen deficiency, weak transportation, water and fluid internal storage, it is easy to produce phlegm and dampness.
Dampness is heavy, sticky and tends to go downward, and because it is a yin evil, it is easy to damage yang qi. Dampness is most likely to trap the spleen and block the qi, which is often manifested as nausea and vomiting, chest tightness and epigastric plumpness, poor appetite, sticky mouth, abdominal distension and other symptoms. Because of the downward tendency of dampness, there are symptoms such as loose stools and turbid urine.
Dampness is difficult to cure because of its sticky nature. Dampness belongs to Yin, so warm medicines should be used to treat this type of disease.
If you have any symptoms, we recommend that you consult a doctor in a timely manner, under the guidance of the doctor to identify the evidence of the treatment, and not to dispose of it on their own, so as not to delay the condition.
