Singers Syrup is ideally recommended in case of tired vocal cords or aphonia. Made on the basis of an ancestral recipe and used by the singers of the choir of the Sistine Chapel in Rome in the 18th century, the Chantres syrup has a specific action on the vocal cords. The sisymbre officinalis, commonly called the Herb aux Chantres contains sulfur compounds that relieve the vocal cords and defatigue the voice. This syrup is suitable for anyone who uses his voice intensely (singers, actors, teachers, lecturers, lawyers ...).
