Tiredness, chest tightness and shortness of breath are mostly related to phlegm-dampness internal obstruction (phlegm and dampness obstructing the internal organs and meridians), liver-qi discomfort (liver-qi stagnation and discomfort), and qi and blood deficiencies, etc., and can be regulated with Chinese medicines such as Er Chen Pills and Gui Spleen Pills. It is recommended to use these medicines under the guidance of professional physicians. Er Chen Pill is composed of Chen Pi, Semixia (made), Poria, and Glycyrrhiza. It has the effect of drying dampness and resolving phlegm (removing phlegm from the body by drying dampness), regulating qi and harmonizing the stomach (regulating qi and harmonizing the spleen and stomach). It is used for cough and phlegm, nausea and vomiting caused by stagnation of phlegm and dampness. Er Chen Pills should not be taken together with tonic Chinese medicines, and are not suitable for coughs caused by lung yin deficiency (deficiency of yin fluid in the lungs), and those who have fever or worsening of symptoms during the period of taking the medication should consult a doctor in a timely manner.
