'urinary-stimulating' is a compound of 'urinary' and 'stimulating'. 'urinary' originates from Latin, specifically the word 'urinarius' (from 'urina') where 'urina' meant 'urine'. 'stimulating' originates from Latin, specifically the verb 'stimulare' (related to 'stimulus') where 'stimul-' meant 'a goad or incentive.'

'urinary' developed from Latin 'urinarius' through Medieval Latin and Middle English into the modern adjective 'urinary'; 'stimulating' developed from Latin 'stimulare' via Old French/Latin-derived forms into English 'stimulate' and its present participle 'stimulating'. The compound phrase 'urinary-stimulating' is a modern English formation combining these elements.

Initially the parts separately meant 'pertaining to urine' and 'to urge or incite'; over time, combined as a compound they evolved to mean 'producing or promoting urination' (i.e., having a diuretic effect).
