Ma Huang (Ephedra sinica) has a long history of use in Traditional Chinese Medicine (TCM) for the treatment of respiratory conditions, including coughs, particularly those characterized as "cold" or "wind-cold" attacks. In TCM, Ma Huang is considered to have warming and dispersing properties, and is traditionally used to "release the exterior," promote sweating, and relieve wheezing and cough by facilitating the flow of lung qi. Its use is typically for acute, externally contracted coughs rather than chronic or dry coughs caused by internal deficiency or heat. The dry cough indication is less well-established in TCM, as Ma Huang can potentially be drying itself and is often combined with other herbs to mitigate this effect and to target specific patterns of disharmony.

From a scientific perspective, Ma Huang contains ephedrine alkaloids, which act as bronchodilators and can help relieve bronchospasm, thus easing cough associated with bronchitis, asthma, and other respiratory conditions. However, the evidence supporting its use for specifically dry cough is limited, and most available studies focus on its bronchodilatory effects rather than cough suppression per se. Additionally, due to safety concerns (notably cardiovascular and central nervous system stimulation), ephedra-containing products have been restricted or banned in many countries. Thus, while traditional use is well documented, modern clinical evidence and safety considerations limit its contemporary application for cough, particularly dry cough.
