Quinine is referenced multiple times in the Jungle Cruise attraction. On the Global Broadcasting Service of Disneyland's Jungle Cruise, Nigel Greenwater brings up a shipment of quinine being delivered to Trader Sam's business, "Tropical Imports" and that distribution will be prioritized for those with pre-existing health conditions. A box of quinine can be seen in the second-floor infirmary of the boathouse.

A jar of, "Quinine Sulphate" pills can be found in the medicine cabinet of the Jungle Navigation Company's Amazon River Base.[2] A removed poster from the Amazon River Base promoted quinine to be included in supplies to prevent complications from malaria.
