Watermelon is a quintessential symbol of summer and its sweet juiciness can quench any thirst. It is a nutrient-rich, pure, and safe food that contains no lipids or cholesterol but other critical nutrients that people need. In conventional medicine, watermelon is considered to effectively fight heat and thirst, work as a diuretic, and counter alcohol and can also be used to treat sore throats, stomach aches, and alcoholism.
