Según la etiqueta "no contiene opio", pero sí cannabis, cloroformo y alcohol (1930)
By the 1820s morphine was a popular anodyne, or soother. Morphine was also, however, a prime method of Victorian suicide. Morphine was six times as potent as opium. It was commercially available, and many upper and middle class patients purchased morphine from doctors and injected themselves daily with newly developed needles. This 'morphinism' was unbounded by legal or social guidelines, and many morphine addicts were unaware of their addiction.
