Rating (out of 5): 3

Thyme (Thymus vulgaris) has a long history of traditional use for respiratory ailments, particularly coughs, including dry cough. Modern scientific studies provide some support for its efficacy. The main bioactive compounds in thyme—thymol and carvacrol—possess antispasmodic, anti-inflammatory, and antimicrobial properties, which may help relax the tracheal muscles and alleviate cough. Several clinical studies have investigated thyme extracts, often in combination with other herbs such as ivy (Hedera helix), in the treatment of acute bronchitis and cough. For example, a randomized controlled trial published in Phytomedicine (2006) found that a combination of thyme and ivy extracts significantly reduced the frequency and severity of cough compared to placebo. Meta-analyses and systematic reviews suggest that thyme, especially in herbal syrups, may be effective in reducing cough symptoms and duration, although the quality of evidence is moderate due to small sample sizes and varying formulations.

Despite these promising findings, thyme is often used in combination with other herbs, making it difficult to isolate its specific effects. Nonetheless, the available data, supported by both pharmacological studies and clinical trials, indicate that thyme has a plausible mechanism of action and some clinical benefit for relieving dry cough. Overall, the evidence is considered moderate (rated 3/5), justifying its use to some extent based on scientific validation.
