History
-
According to the National Park Service, during the U.S.-Mexican War, only about 30 percent of deaths were due to wounds sustained during combats. The rest died from diseases brought on by mosquitoes, dirty drinking water, garbage and lack of hygiene. Soldiers use cactus juice to protect themselves from mosquito bites.
Theories/Speculation
-
A 1911 edition of Scientific American noted that spreading cactus juice on water smothered mosquito larvae and suppressed mosquito populations for up to one year. A manufacturer of cactus extract products also claims that applying extracts from prickly pear cactus to the skin, hair or fur of a mammal could repel mosquitoes.
