Phlegm cautions

If the Qi and Yang are weak and sinking, formulas that move downwards should be used with caution. The relevant formulas here are those that reduce heat and those that purge or break up accumulation of phlegm, Qi and blood. Since these formulas are very active in stimulating the Qi and blood, they may also consume the Qi. Patients may feel tired, especially if they are already Qi deficient. 

In these situations, treatment procedures in TCM that are similar in approach to the hypnotic and sedative drugs should not be used, or used only with caution. Instead, procedures that disperse constrained Qi, clear heat, promote digestion, and remove dampness and phlegm should be applied. Herbs and a diet that tonify the blood should be used for a long period of time. All of these can assist western drugs to calm the mind in an effective way and to reduce their side effects. TCM treatment can thus shorten the course of treatment required with hypnotic and sedative drugs and reduce their dosage. 

Formulas that remove food accumulation should be used with caution during pregnancy as they contain a number of herbs that activate Qi movement to remove food, phlegm and dampness. 

Ban Xia is pungent and warm, and enters the Spleen and Stomach meridians. Although this herb is mostly used for removing phlegm, it can effectively soothe the Stomach and treat nausea and vomiting. It is often used together with other herbs such as Chen Pi to regulate the Qi of the Stomach. Like Chen Pi, it can consume Yin and should be used with caution. 

Patients who suffer from phlegm and dampness accumulation should not use formulas that mostly contain sweet and cold herbs, or must be used with caution as these herbs may increase formation of phlegm and dampness.
