Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Chinese salvia root (Salvia miltiorrhiza, known as Danshen) is primarily used in Traditional Chinese Medicine (TCM) for promoting blood circulation, removing blood stasis, and supporting cardiovascular health. Its historical use for respiratory conditions, including dry cough, is limited and not a primary indication. In TCM, Danshen may occasionally be included in complex formulas aimed at treating coughs—particularly when the cough is believed to be associated with blood stasis or related syndromes. However, it is not considered a chief herb for treating dry cough—herbs like Chuan Bei Mu (Fritillaria) or Nan Sha Shen (Adenophora) are more commonly used for that purpose.

There is minimal scientific research supporting the use of Danshen specifically for dry cough. Most modern studies on Salvia miltiorrhiza focus on its effects on the cardiovascular system, anti-inflammatory properties, and potential neuroprotective actions. Few, if any, clinical trials or pharmacological studies address its efficacy in treating cough, whether dry or productive. Thus, its use for dry cough is supported weakly by tradition and is not substantiated by scientific evidence. Overall, the evidence for using Chinese salvia root for dry cough is very limited and rates low on the evidence scale.
