"Amor seco" is a common name used in Latin America for several plant species, most notably Desmodium adscendens and Bidens pilosa, though it can also refer to other related plants depending on the region. The use of "Amor seco" for chest pain is primarily supported by traditional medicine rather than scientific validation. In some cultures, especially in South and Central America, decoctions or infusions made from the leaves or aerial parts of these plants have been used to alleviate a variety of ailments, including chest pain, which is often interpreted as a symptom of respiratory or cardiovascular issues. However, the specific evidence supporting its efficacy in treating chest pain is largely anecdotal and based on ethnobotanical surveys and traditional knowledge passed through generations. There are no robust clinical trials or pharmacological studies directly demonstrating the effectiveness of Amor seco for chest pain. Some preliminary research does indicate anti-inflammatory and antispasmodic properties in certain species under the "Amor seco" name, which could theoretically provide some relief for musculoskeletal or mild pleuritic chest discomfort, but these findings are not sufficient to establish clinical efficacy for chest pain of cardiac or serious origin. In summary, while there is a tradition of using Amor seco for chest pain in some cultures, scientific evidence to support this use is minimal.
