Valda (or commonly Valda pastille) is a sweet used to relieve throat irritation. This pellet was invented by pharmacist Henri-Edmond Canonne in 1904. The five components of antiseptic Valda pastilles are peppermint , the eucalyptus , the thyme , the wood of guaiac and Landes pine. Pastilles Valda are in reality small green lozenges with a pleasant, aromatic flavor. As with similar products, they have an antiseptic, decongestant, and demulcent action that promises to take care of colds, coughs, and sore throats.
