Respiratory Infections: Most Effective Dietary Supplements

Respiratory infections encompass various diseases affecting the respiratory system, from the upper airways (colds, pharyngitis) to more serious illnesses such as pneumonia. Common viruses responsible include the influenza virus, coronaviruses (including SARS-CoV-2, responsible for COVID-19), respiratory syncytial virus (RSV), adenoviruses, and rhinoviruses. These viruses generally circulate seasonally, from autumn to spring, but COVID-19 spreads throughout the year, with a potential peak in winter. Some populations are more likely to develop severe forms of respiratory infections. The elderly, children under one year (notably for RSV), immunocompromised individuals (e.g., patients with HIV or under immunosuppressive treatment), and those with comorbidities (diabetes, heart, or lung diseases) are at increased risk of complications. Pregnant women are also part of the vulnerable groups. Respiratory infections pose a significant burden on public health, leading to frequent hospitalizations and high demand for healthcare during the winter season. For instance, in France, annual flu and bronchiolitis epidemics require heightened surveillance and prevention strategies such as vaccination.

Natural Prevention

In addition to essential immunity nutrients such as vitamin D, zinc, or vitamin C, herbal medicine also offers essential resources for getting through winter. In the context of respiratory infections, essential oils can be classified according to their specific action, offering a targeted approach to relieve symptoms and support lung function: 1; Essential oils with 1,8-cineole (Eucalyptol): oils such as those from eucalyptus globulus, niaouli, myrtle, and ravintsara are known for their antiviral, decongestant, and mucolytic properties. They facilitate the thinning of secretions and help clear the airways. 1; Essential oils with thymol and/or carvacrol: including thyme, mountain savory, and oregano, these oils have antispasmodic and bronchodilator effects. They help reduce airway spasms and can be used to ease coughing fits. 1; Essential oils with eugenol: clove essential oil, rich in eugenol, is antiseptic and anti-inflammatory. It is particularly useful for soothing inflamed mucous membranes and alleviating pain associated with respiratory infections. 1; Essential oils with pinene: Scots pine essential oil, rich in pinene, acts as a respiratory stimulant and decongestant. It promotes respiration in case of congestion and can be used in inhalation to help open bronchi. Soothing infusions of thyme, mallow, plantain, and German chamomile can also be used to relieve throat irritation and facilitate the elimination of secretions.
