Synopsis

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

Plum fruit (Prunus domestica) has a long history of use in traditional medicine, particularly in East Asian and European folk remedies. In several traditional systems, plums and their preparations (such as syrups, stewed fruits, or decoctions) have been used to help soothe coughs, especially those of a spastic or dry nature. The rationale given in traditional medicine is often based on the moistening and lubricating properties attributed to the fruit, as well as its gentle laxative effect, which is believed to help clear internal heat or dryness that might aggravate coughing.

Despite these traditional uses, there is limited scientific evidence directly supporting the effectiveness of plum fruit for treating spastic cough. Most modern research on plums focuses on their antioxidant content, fiber, and potential benefits for digestion and cardiovascular health. Some laboratory studies have identified anti-inflammatory and antioxidant components in plums, which could theoretically exert a soothing effect on irritated mucous membranes, possibly helping with coughs. However, clinical trials or robust pharmacological studies specifically examining plum fruit for cough relief are lacking.

In summary, while the use of plum fruit for spastic cough is supported by traditional practices, especially in folk medicine, scientific validation is limited or indirect. The evidence level is therefore rated as 2, reflecting anecdotal and historical support with minimal direct research.
