Rating (out of 5): 2

Oregano (Origanum vulgare) has a long history of use in traditional medicine, particularly in Mediterranean and Middle Eastern cultures, as a remedy for respiratory ailments such as coughs. In traditional herbalism, oregano is believed to have warming and drying properties, which is why it has been used to address what is sometimes referred to as “damp” coughs—those characterized by the presence of phlegm or mucus. Herbal practitioners have often prepared oregano as teas, tinctures, or syrups for this purpose. The primary constituents believed to contribute to its effects are volatile oils such as carvacrol and thymol, which possess antimicrobial and mild expectorant properties.

While traditional use is well-documented, scientific evidence supporting oregano’s effectiveness against cough, particularly “damp” cough, is limited. Some laboratory studies show oregano oil can inhibit the growth of certain bacteria and viruses, and may have anti-inflammatory effects, but clinical trials in humans specifically evaluating oregano for cough relief are lacking. As a result, oregano’s use for this condition remains rooted primarily in tradition, with only indirect scientific support from in vitro and animal studies. Its evidence rating is therefore modest.
