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

Pineapple has a long history of use in traditional medicine for treating symptoms of colds and respiratory ailments. The primary component often cited is bromelain, an enzyme mixture found in pineapple stems and juice. In various cultures, pineapple juice has been recommended to soothe sore throats, reduce mucus, and provide general immune support during colds. The belief is that bromelain can help break down mucus and reduce inflammation in the respiratory tract.

However, scientific studies on pineapple’s efficacy specifically as an antiviral against the common cold are limited. Some research has shown that bromelain possesses anti-inflammatory and mucolytic (mucus-dissolving) properties, which could theoretically help ease some symptoms associated with respiratory infections, but direct antiviral effects against cold-causing viruses (such as rhinoviruses or coronaviruses) have not been conclusively demonstrated. Most scientific validation comes from small-scale studies or animal models, and there is insufficient high-quality clinical data to firmly establish pineapple or bromelain as effective antiviral agents for the treatment or prevention of colds.

In summary, the use of pineapple for colds is primarily rooted in traditional practices, with some plausible mechanisms identified in laboratory settings. The scientific evidence supporting its use remains preliminary and does not yet justify strong recommendations for its use as an antiviral treatment for colds.
