Basil (Ocimum basilicum) has a long history of use in traditional medicine systems, particularly in Ayurveda and traditional Chinese medicine, for the management of respiratory ailments such as colds, often accompanied by fever. In Ayurvedic practice, basil (especially the variety known as holy basil or Tulsi) is considered an effective remedy for symptoms of the common cold, including cough, nasal congestion, and mild fever. Its leaves are often used in teas or decoctions, sometimes combined with other herbs and honey, to help alleviate these symptoms.

The rationale for its use stems from its purported properties as an expectorant, diaphoretic (promoting sweating to reduce fever), and antimicrobial agent. Some in vitro and animal studies suggest that basil extracts possess anti-inflammatory, immunomodulatory, and mild antimicrobial effects, which could theoretically contribute to symptom relief. However, robust clinical evidence in humans remains limited; most data come from traditional texts and anecdotal reports rather than large-scale, placebo-controlled trials.

Overall, the use of basil for colds with fever is primarily supported by tradition rather than strong scientific validation. Its popularity persists in many cultures due to its perceived safety, accessibility, and historical precedent, but healthcare providers generally recommend more evidence-based therapies for managing cold symptoms and fever.
