Synopsis

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

Pineapple has traditionally been used in some cultures as a remedy for colds and to help relieve congestion. The rationale behind this use is largely attributed to the presence of bromelain, an enzyme found in pineapple juice and stems, which has anti-inflammatory and mucolytic (mucus-thinning) properties. Historically, folk medicine in tropical regions has promoted pineapple for soothing sore throats and easing coughs. However, scientific evidence supporting pineapple’s effectiveness specifically as a decongestant or cold remedy remains limited.

Some small studies and laboratory research suggest that bromelain may help reduce inflammation and thin mucus, potentially offering mild relief for symptoms like congestion. However, the majority of available studies either involve bromelain extracts at higher concentrations than found in dietary pineapple, or are not directly related to cold symptoms in humans. Major clinical guidelines do not recommend pineapple as a primary treatment for colds or congestion.

In summary, the use of pineapple for treating cold symptoms is primarily justified by traditional practices rather than robust scientific evidence. While the theoretical basis exists due to bromelain’s properties, the quality and quantity of scientific data supporting its use for this purpose are low, meriting a score of 2 out of 5.
