Cautions

contraindication Cough from Lung Yin deficiency

contraindication A warm, drying formula: avoid, or modify, where Phlegm-Heat, dry Phlegm, or Lung Qi or Yin deficiency with a dry cough is the main picture

caution Watch for signs that the picture has shifted towards Heat or Dryness (dry cough, thick yellow sputum, dry mouth, red tongue with scant coat): its warm, drying herbs would make these worse

caution Only processed Ban Xia is used; the raw herb is toxic and never taken internally

caution Not to be combined with Wu Tou, Fu Zi or other aconite herbs, which Ban Xia is classically incompatible with

pregnancy Ban Xia carries a traditional pregnancy caution as a mildly toxic, downward-directing herb; use in pregnancy only under a qualified practitioner
