A composition for use in the treatment of oropharyngeal cavity affections, wherein the composition is in a fluid form or a solid form, wherein, when the composition is in the fluid form, the composition consists of: Poplar buds extract at a percentage in weight from 0.1 to 70%, Excipients at a percentage in weight from 1 to 80% Solvents at a percentage in weight from 0 to 80% Natural or lyophilised fruit juices at a percentage in weight from 0 to 50% Natural or artificial flavours at a percentage in weight from 0.05 to 2% Essential oils at a percentage in weight from 0.01 to 1%; and when the composition is in the solid form, the composition consists of: Dry poplar buds extract at a percentage in weight from 0.5 to 10%, Excipients at a percentage in weight of 10-97% Natural or artificial flavours at a percentage in weight from 0.5 to 3% Essential oils at a percentage in weight from 0.05 to 1% Powdered or lyophilised fruit juices and/or natural extracts at a percentage in weight from 0.5 to 15% Sweeteners at a percentage in weight from 1 to 10%, wherein said extract of poplar buds is an extract obtainable by a process comprising the following steps: a. preparing a hydro-alcoholic extract of poplar buds by extraction with 85° ethanol b. preparing a hydro-alcoholic extract of poplar buds by extraction with 13° ethanol c. obtaining a multi-fraction alcoholic extract, by mixing the extracts prepared in a. and b. d. decanting and/or centrifuging and filtering said alcoholic extract (c.) collecting the supernatant e. subjecting the filtered supernatant obtained in d. to concentration and freeze-drying and, optionally, f. adding to the filtered supernatant obtained in d. arabic gum and then subjecting it to concentration and lyophilisation.
