Pohu BL-42 has influence over both physical and psychological disorders.
As its name indicates, it treats disorders of the Corporeal Soul (Po) and emotional disorders related to Lung disharmony. It strengthens and roots the Corporeal Soul in the Lungs, by releasing emotional feelings such as long-term worry, sadness and grief. It has the effect to calm the Mind and sooth the spirit, so that the patient turns inwards and become more comfortable with themselves.
Furthermore, BL-42 promotes the descending of Lung Qi. Thus it also treats wheezing, dyspnoea and breathlessness.
