In this hot summer, a piece of sweet and delicious watermelon is definitely the greatest fun of the whole summer. There are many types of watermelons on the market today, including seeded, seedless, white, black and green.

The dazzling array of watermelons sometimes gives headaches to some people who have difficulty choosing . However, no matter how many types of watermelons there are, they all have one thing in common: they are edible.

So are there any watermelons in the world that cannot be eaten?

The answer is of course yes. In ancient my country, watermelon had a very special name called cold melon. Because watermelon has a long storage period, ancient people often stored watermelon to survive the long winter. Over time, people thought that watermelon was very cold-resistant, so they named it cold melon.

Unfortunately, the ancients did not have the opportunity to visit other parts of the world. If there is such an opportunity, it will definitely refresh their concept of watermelon. In North Africa Turkey and Afghanistan and other places, there is a kind of watermelon called medicinal watermelon . In many areas, it is also called wild watermelon , or it can also be said as medicinal gourd.

From the appearance point of view, this medicinal watermelon is very similar to a normal watermelon. Except for its smaller size, there is almost no big difference. Generally speaking, watermelon is a plant that likes sunshine and dryness. The drier the weather, the sweeter the watermelon will be. Compared with normal watermelons, medicinal watermelons prefer hot and dry environments, so this kind of watermelons usually only appear in deserts.

digression : From this point of view, if you want to find water sources in the desert, watermelon is definitely the best choice as a water source. However, the reality may disappoint everyone.

When you see a watermelon in the desert, the last thing you can do is open it without hesitation and quench your thirst with its sweet flesh. The reason is very simple. The taste of medicated watermelon is not as sweet as normal watermelon. Instead, it is full of light bitterness, which can even make it difficult to swallow.

Although its taste is not very good, there is a lot of moisture inside. However, using watermelon to quench your thirst will not only fail to quench your thirst, but may even pose a huge threat to your life.

Medicinal watermelon, although there is a word "medicine" in its name, it has no curative effect. The reason why it has such a name is because it can poison people to death.

According to the research of scientists, medicinal watermelon contains a large number of toxic substances, including alkaloids, resin glycols and citrulline. After these toxic substances enter the human body, they will cause dizziness, diarrhea, hypothermia, and liver and kidney cell necrosis. The most frightening thing is that it may also cause severe dehydration.

Just imagine, if you accidentally swallow the medicine watermelon in the desert, it is almost equivalent to being sentenced to death in advance. However, the medicinal watermelon is not useless. For example, scientists now dry the medicinal watermelon and extract a drug called colonin from it. This substance has a very powerful diarrheal effect and is usually used to treat constipation and other defecation difficulties.

As the ancients said, medicine is three parts poison, and poison is three parts medicine. But for us ordinary people, no matter what the circumstances, it is best not to use watermelons growing in the wild. At worst, it may cause diarrhea, and at worst, it may kill you on the spot.
