And the Greek father of medicine, Hippocrates, described scurvy symptoms nearly 2500 years ago, around the same time that the Chinese monk Sphaxian reported the use of ginger on ships was being used to prevent it. Without Facebook, without Twitter, this life-saving knowledge was repeatedly lost and then found, and then lost, and then found, all the way up until the 1900s. Now the largest death tolls due to scurvy were during the long sea voyages undertaken during the age of exploration. Now some of you may have heard of Ferdinand Magellan, the famed Portuguese explorer who created a trade route, the first one, between Europe and India. In 1520, you might not know, that out of 230 of his sailors, 208 died mainly due to scurvy. During the 1700s, scurvy killed more British sailors than wartime action. And one more example which blows my mind.
