The card does not name a season or situations in which the syrup is taken. It gives one regimen: adults and children over 12, 10 ml twice a day 30 minutes before meals; the recommended daily amount must not be exceeded. The syrup does not replace a complete and varied diet; after opening it is kept in the refrigerator and used within 3 months.
General information (not a manufacturer's instruction): the card does not state the duration of intake – it is better to discuss it with a doctor or a specialist.
