Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Ilex is a genus of plants that includes species such as Ilex paraguariensis (Yerba mate) and Ilex aquifolium (European holly). The use of Ilex species for the prevention of colds is primarily rooted in traditional medicine, especially in regions where these plants are native. For example, Yerba mate has been consumed in South America for centuries as a health-promoting beverage, and traditional uses sometimes include claims of “strengthening the body” or enhancing resistance to illness. European holly, on the other hand, has a history of use in folk remedies, though not specifically or widely as a cold preventative.

Scientific validation for Ilex as a cold preventative is limited. Some laboratory studies have shown that extracts of Ilex species possess antioxidant and mild immunomodulatory properties, but there is little to no direct clinical evidence that drinking Ilex tea or consuming extracts prevents the onset of colds. The traditional use rating is low because while there is a general history of use for supporting health, explicit references to cold prevention are sporadic and not central to the ethnomedical uses of these plants. Overall, while Ilex may be consumed as part of a healthy lifestyle in traditional contexts, its use for cold prevention is not well-supported by scientific research.
