Herbs
that resolve phlegm and stop cough and asthma are used in cases with profuse
sputum; thick, sticky phlegm; asthma; or symptoms related to phlegm, such as
scrofula, goiter, epilepsy, convulsions and yin carbuncles.
The
selection of herbs depends upon the cause and manifestations. For example,
if phlegm is accompanied by an exterior syndrome, herbs that release the
exterior are added. If phlegm is complicated with heat signs, herbs that
clear heat are put into the formula. If tan interior cold syndrome exists,
herbs that warm the interior and dispel cold are added to the formula. If
there are signs of cough and asthma with fatigue or weakness, herbs that nourish
and tonify are added. For epilepsy and convulsions, herbs that pacify the
liver, subdue endogenous wind and tranquilize the mind are added. For yin
carbuncles, herbs that dispel cold and remove stagnation are added.
