Synopsis

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

Radish (Raphanus sativus) has a long history of use in traditional medicine systems, particularly in Ayurveda, Traditional Chinese Medicine (TCM), and various folk remedies, for addressing coughs and respiratory complaints, including dry cough. In these traditions, radish is believed to have expectorant properties, helping to loosen mucus and soothe irritation in the throat. Preparations often involve radish juice, sometimes mixed with honey, which is thought to moisten the throat and reduce cough reflex.

However, scientific validation for these effects remains limited. Some laboratory studies indicate that radish contains bioactive compounds such as glucosinolates, isothiocyanates, and vitamin C, which may have mild anti-inflammatory and antimicrobial effects. Nevertheless, robust clinical trials specifically examining radish's efficacy in treating dry cough in humans are lacking. Most current support for its use comes from historical texts, anecdotal reports, and small-scale studies.

In summary, while radish is traditionally employed for dry cough in various cultures and may offer some soothing relief, the evidence supporting its effectiveness is mainly traditional rather than scientific. The overall quality and quantity of evidence are low, so it should not replace proven therapies, but it may serve as a complementary remedy in some cases.
