"Pussy Ears" typically refers to the plant Cyanotis somaliensis, but in herbal medicine, the name may also refer to Orthosiphon aristatus (commonly called "Cat's Whiskers" or "Java Tea") or Kalanchoe tomentosa. There is some ethnobotanical evidence that certain "Pussy Ears" species have been used in traditional medicine systems, primarily in Asia and Africa, to help alleviate symptoms of colds, including congestion. The use is mainly based on traditional knowledge and anecdotal reports, rather than rigorous scientific studies. Traditional preparations might involve making teas or decoctions from the leaves to help clear nasal passages and relieve cold symptoms. However, there is little to no published clinical research supporting the efficacy of "Pussy Ears" as a decongestant or cold remedy. The rating of 1 reflects that while the use is rooted in traditional practices, there is minimal scientific validation, and the mechanism of action has not been clearly established. In summary, while "Pussy Ears" has a history of traditional use for respiratory complaints, its use as a decongestant for colds is not supported by strong scientific evidence.
