Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Chinese orchid, commonly referring to Bletilla striata (also known as "Bai Ji" in Traditional Chinese Medicine), has a long history of use in Chinese herbal medicine for the management of coughs, particularly dry or irritating coughs. Traditional Chinese medical texts and materia medica describe Bletilla striata as having properties that "moisten the lungs" and "stop bleeding," and it is frequently included in classical formulations aimed at addressing dry coughs caused by lung yin deficiency or damage from chronic irritation.

Modern scientific research on Bletilla striata has primarily focused on its wound healing, anti-inflammatory, and hemostatic properties, with relatively limited direct investigation into its efficacy for cough, especially dry cough. While some laboratory studies indicate that polysaccharides and other constituents of Bletilla striata have anti-inflammatory and soothing effects on mucous membranes, there is a lack of robust clinical trials specifically addressing its use for cough relief in humans.

In summary, the application of Chinese orchid (Bletilla striata) for dry cough is primarily rooted in traditional Chinese medical practice, with only limited preclinical evidence suggesting possible relevance. There is currently insufficient high-quality scientific validation to support its widespread use for this condition by modern standards.
