Herbs that Transform Phlegm and Stop Coughing 化痰止咳平喘药

Overview

A chlorite schist mineral, crushed and usually calcined before use. Heavy and downward-driving, it is the specific for old congealed phlegm that ordinary expectorants will not shift — the phlegm behind stubborn wheezing, and behind phlegm-fire mania and epilepsy. It is the signature ingredient of Gun Tan Wan, and because of its force it is given briefly and for genuine excess only.

Contraindications

Cautions

A heavy, driving mineral for excess patterns only: not for weak, elderly or chronically ill patients, not for cough from deficiency or dryness, and given to children only briefly and under supervision. Prolonged use injures the middle qi — stop once the phlegm has moved. Crush it and decoct it before the other herbs.

Contraindicated in pregnancy: Contraindicated in pregnancy.
