sentences:  A medicine developed by Aboriginal peoples of the eastern states of Australia, from the soft corkwood tree, or "Duboisia myoporoides", was used by the Allies in World War II to stop soldiers getting seasick when they sailed across the English Channel on their way to liberate France and defeat Hitler during the Invasion of Normandy.It had been flown over to Europe and developed in great secrecy by Canadian researchers, before the "mystery pill" was dispensed to every participating soldier for the massive military operation, which was pivotal to winning the war but had been delayed several times because of seasickness.Later, it was found that the same medicine could be used in the production of the tropane alkaloid drugs, scopolamine and hyoscyamine, which are useful for eye surgery, and a multi-million dollar industry was built in Queensland based on this substance.
