Cold: Most Effective Dietary Supplements

The common cold is a mild respiratory infection mainly caused by viruses such as rhinoviruses and coronaviruses, responsible for 50% and 10-20% of acute upper respiratory infections, respectively. These viruses spread through direct person-to-person contact or via contaminated surfaces, infecting the mucous membranes of the nose and sometimes the eyes. The infection activates an immune response that leads to a series of classic symptoms. Rhinoviruses proliferate in the upper respiratory tract, where the temperature is favorable for their multiplication (33-35°C). When these viruses enter the nasal passages, they attach to epithelial cells, causing the release of inflammatory cytokines. This response leads to mucosal swelling, increased mucus secretion, and the stimulation of sneezing and coughing reflexes. In the early stages, symptoms may appear just 2 hours after exposure to the virus.

Symptoms and Signs

The initial symptoms of a cold, such as a runny nose, sneezing, and a burning sensation in the nose, generally appear 1 to 2 days after exposure to the virus. They peak in intensity after 2 to 3 days and usually resolve within 10 days without complications. In some cases, a slight fever, loss of smell and taste, and fatigue may be added.

Risk Factors

The risks of catching a cold increase under certain conditions: • Weakened immune defenses • Periods of stress or increased fatigue • Poor quality sleep • Vitamin C deficiency • Exposure to unfavorable environmental conditions (cold, humidity, tobacco smoke)

Prevention

To prevent colds and strengthen the body's resistance: • Boost immunity: with nutrients like vitamin C, zinc, and by incorporating immune-stimulating plants. • Maintain a healthy environment: regular airing of living spaces, humidifying the air if necessary. • Hand hygiene: regular hand washing reduces the transmission of viruses responsible for colds.

Treatments

To treat colds naturally, several effective options can be considered, including essential nutrients, medicinal plants, essential oils, and lactic ferments: • Essential nutrients: Vitamin C and zinc are essential to support the immune system. Vitamin C helps to reduce the duration of symptoms, while zinc contributes to the proper functioning of the immune system. • Medicinal plantsThe echinacea and astragalus strengthen natural defenses, while andrographis and eleuthero alleviate symptoms due to their antiviral actions. White willow helps to relieve fever and pain. • Essential oilsEssential oils of thyme, eucalyptus, and ravintsara, known for their decongestant and antiviral effects, clear the airways and thin nasal secretions. • ProbioticsA balanced microbiota is essential for immunity. Lactic ferments help to strengthen natural defenses.
