What is a common use of Gnaphalium sp.?

Gnaphalium sp., commonly known as cudweed or rabbit tobacco, has been traditionally used for its medicinal properties, particularly in the preparation of herbal teas. These teas are often utilized for treating respiratory ailments, including coughs and bronchitis, due to the plant's expectorant qualities. This makes the use of Gnaphalium sp. for making teas to alleviate coughs a well-established application in herbal medicine.

In contrast, while other uses such as reducing lower back pain, identifying medicinal plants, or pharmaceutical development may relate to other plants or have some relevance, they do not specifically align with the traditional or documented uses of Gnaphalium sp. The focus on its application in teas specifically targets the respiratory benefits that many herbalists and practitioners have recognized over time.
