J'adore ce produit que je prends en prévention, tous les matins avant d'aller travailler avec le public, très près des gens, je me sens protégée.
Je le prends aussi dès que je sens un petit mal de gorge naître et tout de suite cela disparaît.
J'utilise la plupart des produits que cette compagnie distribue car je trouve qu'ils sont d'excellente qualité et efficaces. Merci pour votre bon travail !

A very fast cure!

Yesterday I woke with a searing sore throat. I took the spray, then I misted my sinuses, and it burned an order of magnitude worse than when I tried it beforehand. It was almost unbearable. But within a few hours, my throat was feeling 100%. This morning, no sore throat!
