Study questions plant-based cold remedies

A recent analysis by Anne-Sophie Stamane and Audrey Vaugrente challenges the effectiveness of plant-based cold remedies, suggesting that products like infusions, essential oils, and plant-based tablets may not work as intended or could even be harmful.

Products claim to help with colds and immunity

Many of these remedies are marketed with promises of decongesting, boosting immunity, acting as disinfectants, and improving sleep. However, the analysis suggests these claims are not supported by evidence.

Several plant-based products are on the market

The study highlights various plant-based cold remedies available in pharmacies, including Actirub cold, Activox cold pelargonium, Humer nose-throat day/night, L52 rub, Olioseptil sinuses, Polanine respiratory comfort, Sinufix cold, Solacy adult, and Acetylcysteine.

Acetylcysteine is authorized but not reimbursed

Acetylcysteine, also known as "N-acetyl-L-cysteine," is approved as a drug to thin mucus secretions. However, it is not covered by insurance because its effectiveness for this purpose has not been sufficiently demonstrated.

Caution advised for certain groups

The analysis advises people who are pregnant, breastfeeding, or have chronic illnesses to consult a doctor before using plant-based cold remedies, due to potential risks or lack of proven benefits.
