Aloe vera has a long history of traditional use for various health conditions, primarily related to skin ailments, burns, and digestive issues. In some traditional medicine systems, aloe vera juice or gel has been used to support the immune system and maintain general health, which has led to its inclusion in some folk remedies for cold prevention. However, there is very limited direct historical evidence specifically linking aloe vera to the prevention or treatment of the common cold. The rationale for its traditional use is mostly based on the belief that aloe vera possesses general immune-boosting properties due to its content of polysaccharides, vitamins, and antioxidants. These components are thought to help the body resist infections. However, traditional texts and remedies rarely cite aloe vera as a primary agent for colds; instead, it is more commonly discussed as a supporting ingredient for overall wellness. From a scientific perspective, there is currently insufficient evidence to support the effectiveness of aloe vera in preventing or treating the common cold. Most studies focus on topical uses or digestive benefits, and few have rigorously examined its impact on respiratory viruses. Therefore, while there is some traditional precedent for its use in supporting immunity, the evidence is weak, and it should not be relied upon as a primary preventive measure for colds.
