Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Cassia, which may refer to either Cinnamomum cassia (Chinese cinnamon) or Senna species, has a long history of use in traditional medicine, particularly in Chinese and Ayurvedic systems. When it comes to the prevention of colds, Cassia (specifically Cinnamomum cassia) is mentioned in traditional Chinese medicine (TCM) texts as a warming herb believed to dispel cold, support the immune system, and promote circulation. It is a key ingredient in classical formulas such as Gui Zhi Tang, used to treat early stages of cold and flu, especially those presenting with chills and mild fever.

However, robust scientific evidence to validate the effectiveness of Cassia for cold prevention is limited. While some laboratory studies have shown that cinnamon bark possesses antimicrobial activity and may modulate immune response, these findings are preliminary and have not been translated into clear clinical recommendations for cold prevention in humans. The majority of support for Cassia’s use in this context remains rooted in centuries of empirical observation and traditional practice rather than randomized controlled trials. Therefore, while there is a strong foundation in traditional use, the evidence from a scientific standpoint is modest (rated 2/5), reflecting preliminary data and traditional reliance rather than rigorous clinical validation.
