Plantago species (such as Plantago major and Plantago lanceolata) have a long history of use in traditional herbal medicine, particularly for respiratory and inflammatory conditions. In various traditional systems, Plantago leaves or seeds have been employed to soothe coughs, bronchitis, and irritation of the respiratory tract, which may sometimes be associated with chest discomfort or a sensation of chest pain. However, these uses are generally aimed at relieving symptoms related to mild respiratory conditions rather than directly treating chest pain of cardiac or other serious origins.

There is little to no robust scientific evidence supporting the use of Plantago specifically for the treatment of chest pain, particularly in the context of angina or other serious medical conditions. Most available studies focus on its effects as a demulcent, anti-inflammatory, or expectorant, which may incidentally provide some relief in cases where chest discomfort is linked to respiratory irritation. Traditional texts and ethnobotanical surveys occasionally mention Plantago for chest complaints, but typically without rigorous clinical validation.

In summary, while Plantago has traditional applications related to respiratory health that could incidentally address mild chest discomfort, there is minimal direct scientific evidence, and it should not be considered a validated or primary treatment for chest pain.
