In the 18th century, scurvy was prevalent among seafaring sailors because of their remoteness from land and lack of fresh fruits and vegetables, as well as among long-stranded army soldiers, chronically underfed communities, besieged cities, prison prisoners and labor camps.

For example, gold miners in California 140 years ago and gold miners in Alaska 90 years ago had large numbers of cases of scurvy.

The symptoms of scurvy at the beginning are weakness of the limbs, loss of spirit, irritability, fatigue from any work, and easy redness and swelling of the skin. The patient may feel muscle pain and mental depression. Then his face swelled, his gums bleed, his teeth fell out, and he had bad breath. There was a large area of bleeding under the skin, which looked like a serious bruise. Finally, severe exhaustion, diarrhea, difficulty breathing, fractures, liver and kidney failure leading to death.

The calamities of scurvy death among seafarers in the early years are innumerable, as their food on the voyage consisted of bread, fish, and bacon, which contained very little vitamin C.

And listening to what the old man said, the symptoms are exactly the same as scurvy, don't these people eat fruits and vegetables? No, this old man looks like he must be sixty or seventy, why can he live so long?

Thinking of this, Zhang Tianyuan decided to do an investigation first.

"Who is the old gentleman here?"

"Old decay is the high priest here. The old man replied.

"Then Mr. High Priest, can you let us drink some water and eat something first, and then help your people see a doctor?" Zhang Tianyuan tried to ask.

From the diet, you may be able to see what is wrong.

When the high priest heard this, he hurriedly turned back and shouted. Obviously, I was a little anxious, because I was afraid that God would be angry.

Meals were prepared quickly. But for this meal, apparently Big Cat and Lightning will be more satisfied. And he frowned a little, and seemed to be aware of the problem, because this meal, except for fish or fish, there were no vegetables and fruits, which is not surprising if there is scurvy.

After confirming this matter, Zhang Tianyuan ate fish and drank soup while thinking about the high priest. The old guy is sixty or seventy years old, there must be some difference between the diet and others, and it is estimated that there are other similar diets in this tribe, otherwise, it is difficult to explain that there are more than ten old men and old ladies in it.

After eating, Zhang Tianyuan went to check on the person who was currently sick, and found that it was undoubtedly scurvy.

However, this disease, the earth qi is also powerless, which is a lack of vitamin C. His earth qi can't be supplemented with vitamins.

So he went to the high priest's house, intending to ask the high priest if he usually had a small stove, but when he got to the house, he immediately understood.

There was tea in the high priest's house!

Tea can be regarded as the nemesis of scurvy.

In the Ming Dynasty. China's tea industry has developed greatly, and the Ming Dynasty changed the method of decoction of cake to brew loose tea, and advocated the beauty of nature. Tea culture to the extreme. In the spread of Chinese tea culture, Zheng He played a great role in going to the West. Zheng He went to the West. The silk, porcelain, and tea of China were brought to overseas countries, and the rise of loose tea became a major turning point in the development of Chinese tea. The Asian and African countries such as Thailand, Malaysia, Singapore, Sri Lanka, India, and Kenya that Zheng He went to the West have all become today's tea powers.

Another contribution of Zheng He's trip to the West to Chinese tea is to make people pay more attention to the health care of tea.

In 1519, the Portuguese navigator Magellan led an ocean-going fleet from the east coast of South America to the Pacific Ocean. Three months later, some of the crew's gums were broken, some of the crew members had nosebleeds, some of the crew members were weak, and when the ship arrived at its destination, only 35 of the original 200 people survived, and people could not find a reason for this. This severe disease came to be known as scurvy.

In 1734, on a ship bound for Greenland, one of the crew members fell ill with a severe scurvy that could not be cured at the time, and the rest of the crew had to abandon him on a desert island. When he woke up, he ate wild grass and coarse tea, and after a few days his scurvy was cured.

Interestingly, there is no record of scurvy among the crews of ancient Chinese ocean-going fleets. From the relevant historical materials of Zheng He's voyage to the West in the Ming Dynasty, it is known that Zheng He went to the West seven times and never had scurvy. Later investigations of the Chinese crew's recipes revealed that green tea, soybean sprouts made from soybeans, and the Chinese crew also used wooden barrels to grow vegetables, all of which were rich in VC and saved the Chinese crew from the threat of scurvy.

Now we know that scurvy is caused by a lack of vitamin C in the human body, and Chinese green tea is rich in vitamin C.

In the middle and late stages of World War II, due to the continuous escalation of the war, Japan's economy was in trouble, and the supply of the Japanese army was difficult. The 91st Division, stationed on the northern islands of Japan, suffered from malnutrition due to long-term food shortages. Although the 91st Division did not participate directly in the battle, soldiers often died in the line of duty. The divisional logistics department found that the cause of death of the soldiers was a severe deficiency of vitamin C, and most of the soldiers died of scurvy. The logistics department found that the most feasible way was to drink crude tea leaves, which are rich in vitamin C.

The Japanese navy has lived at sea for many years and relies on drinking coarse tea to prevent and treat vitamin C deficiency, and most of Japan's coarse tea is controlled by the navy, so the commander of the 91st Division sent people to forge the navy's coarse tea tickets and fraudulently receive a batch of coarse tea for officers and men to drink, thus successfully preventing the spread of scurvy. These coarse teas came to be known as "life-saving teas".

In the present, it seems that it is the vitamin C in tea that plays a role. Vitamin C, also known as ascorbic acid, is also called "scurvy" when vitamin C is deficient, causing bleeding in the gums, muscles, joint capsules, serous cavities, etc. Especially in naval battles and navigation, scurvy that occurs due to the lack or severance of the supply of vitamin C-containing foods can be prevented and treated by eating tea and so on.

Expert testing has found that the content of vitamin C in tea is much higher than that of fruits such as lemons, pineapples, apples, pancakes, and oranges.

For example, the content of vitamin C in 100 grams of lemons, oranges and tomatoes is less than 100 mg, and the vitamin C in apples and pineapples is even less, only about 20 mg.

100 grams of unfermented tea contains 100-500 mg of vitamin C, and the content of high-quality high-grade green tea is more, often more than 250 mg, and the content of black tea is less.

The human body's need for vitamin C is about 60 mg a day, and in the case of a normal diet, drinking 3-5 cups of tea a day can basically meet the body's need for vitamin C.

This is especially important in situations where there is a lack of fruits and fresh vegetables.

The old priest's tea leaves are green tea, and it would be strange if you could still get scurvy if you drank tea every day.

"High Priestess, where did you get this?"

"This, this is what our people picked up when they went out fishing, there are a lot of them, but most people don't like it, I think it's good to use it to soak in water, so I drank it, but I didn't expect to like it more and more when I drank it. The High Priest explained.

"Ah!" Zhang Tianyuan clapped his hands and said: "High priest, hurry up and take these tea leaves, yes, this is the tea you drink, this is the medicine that God has given you to solve the epidemic, just drink a cup like you every day." ”

"Is this true?"

"High Priest, you don't believe my words?" Zhang Tianyuan said with a frown.

"Don't dare, don't dare. ”

The high priest looked at Zhang Tianyuan with awe, and hurriedly went to announce the order.

It turned out that these tea leaves were left after the accident of the merchant ships passing here, and the fish-eating people all picked them up, and saved a lot, enough for hundreds of people to drink for several years, but this is not the fundamental way to solve the problem, he just looked around, there is a small amount of good land on this peninsula, but there is not a wild fruit tree, let alone a vegetable field, he feels that if he really wants to get rid of the harm of scurvy for a long time, he still has to start by planting vegetables and fruits.

But there's no hurry about this matter, let's talk about it later, having those green teas right now is enough to solve the problem, and after he leaves here, he will think about how to help the people here.

It's not that he has a good heart, if he is really saved because of the people here, then these natives are his Zhang Tianyuan's saviors, and he helps a little bit, so it's not a problem at all.

After solving the matter of the fish-eating clan, Zhang Tianyuan settled down temporarily, and every day there would be fishermen from the fish-eating clan going out to fish, and if there were boats nearby, they would come back and tell Zhang Tianyuan.

However, I don't know if it's too remote here, two or three days have passed, and there are still no ships passing by, Zhang Tianyuan was worried at first that he would stay too long, and the natives here would be worried about his treasures, but obviously he thought too much, these people didn't have any idea about his treasures at all, it was better to say that they like tea now, and it was completely better than gold.

After being bored, Zhang Tianyuan also went out with the fishing boat of the Fisheaters, but the problem was that the fishing boats of the Fishivores were too simple to sail too far, so they had to return to the peninsula.

In this process, Zhang Tianyuan also worked hard, but the farther away from the peninsula, the greater the danger, and as a result, a wave directly overturned the small wooden boat, and finally the great white shark beckoned his little brother to save him and the fishermen of the fish-eating tribe.

Although in the past two days, the person with scurvy has obviously improved, and he has won the complete respect of this tribe, but it is not enough, there are no electronic components or anything like this tribe, and it is basically impossible to ask for help.

Zhang Tianyuan tried to go to sea with a wooden boat several times without believing it, but in the end it was still in vain, and he had to accept this helpless reality.

He now understood why Robinson had been on the island for so long and couldn't leave on his own, because it would be an almost impossible nightmare for such a small wooden ship to go to sea.

Some of the scenes in the movie are simply deceitful and deceitful, and how long it takes to drift alone in a canoe to be saved, is that really possible? )
