Effects and functions of grapefruit peel

This is the season when grapefruits are on the market in large quantities. Most people tend to throw away the grapefruit peel after eating the grapefruit flesh, which is actually a pity. Because grapefruit peel is edible, it is not only rich in nutrients, but also has therapeutic effects such as warming the stomach, resolving phlegm, and moistening the throat.

Among the many autumn fruits, grapefruit is the largest, usually weighing more than 1,000 grams. It matures around August 15th of the lunar calendar every year and has a thick skin and is durable to store, so it is known as a "natural canned fruit."

Grapefruit has high nutritional value, containing very rich protein, organic acid, vitamins and essential elements such as calcium, phosphorus, magnesium, sodium, etc., which is difficult to match by other fruits. Every 100 grams of grapefruit contains 0.7 grams of protein, 0.6 grams of fat and 57 kcal calories.

Grapefruit not only has high nutritional value, but also has the effects of strengthening the stomach, moistening the lungs, replenishing blood, clearing the intestines, and facilitating bowel movements. It can promote wound healing and has a good auxiliary effect on septicemia. In addition, because grapefruit contains physiologically active substances such as glycosides, it can reduce blood viscosity and reduce the formation of blood clots, so it also has a good preventive effect on cerebrovascular diseases such as cerebral thrombosis and stroke. Fresh grapefruit meat is an ideal food for diabetic patients because it contains ingredients similar to insulin. Traditional Chinese medicine also believes that grapefruit is sweet and sour in taste and cold in nature. It has the effects of regulating qi and resolving phlegm, moistening the lungs and clearing the intestines, replenishing blood and strengthening the spleen. It can cure symptoms such as poor appetite, bland mouth, and indigestion. It can help digestion, remove phlegm and quench thirst, and regulate qi and disperse knots.

According to traditional Chinese medicine, pomelo meat is sweet and sour, cold and non-toxic, and has the effects of regulating qi, moistening the lungs and clearing the intestines, nourishing blood and strengthening the spleen.

It can cure symptoms such as poor appetite, bland mouth, and indigestion. Regular consumption can help digestion, remove phlegm and quench thirst, and regulate qi and disperse knots.

In addition, grapefruit has the effects of strengthening the stomach and spleen, moistening the lungs, replenishing blood, clearing the intestines, and facilitating bowel movements. It can promote wound healing and has a good effect on sepsis. Modern medicine has also found that grapefruit has the effects of preventing cerebral thrombosis, anti-cancer, and weight loss, and is most suitable for middle-aged and elderly people to eat.

Grapefruit contains physiologically active substances such as naringin and hesperidin. Naringin can reduce the viscosity of blood circulation and reduce the formation of blood clots. For middle-aged and elderly people who suffer from cerebrovascular diseases, eating grapefruit regularly can help prevent stroke. Grapefruit contains a lot of vitamin C and calcium, which helps prevent the occurrence of intestinal cancer and gastric cancer.

Grapefruit peel effects:

1. Boil grapefruit peel in water to treat pneumonia in children

After eating the grapefruit, leave the skin and dry it, put a few pieces into the pot and add water to cook together (the pieces should not be too small, otherwise the medicinal effect will be reduced, but they should not be too large either), and do not use too much water (same as decocting Chinese medicine). After boiling it several times, pour the boiled soup into a bowl and let the child drink it. He will get better after drinking it several times.

2. Boil grapefruit peel in water to treat frostbite

Boil water with dried grapefruit peels. When the water is very thick, apply it to the frostbitten area, but avoid the broken skin. Pay attention to the temperature of the hot compress. At the beginning, the temperature of the towel should not be too hot. You can shake it to get some heat before applying it. After the frostbitten area has adapted, gradually increase the temperature. When the temperature is the highest, take the towel out of the pot and apply it directly to the hot compress.

This method requires patience and long-term persistence (even if you are well, it is best to persist until the end of this winter). It can promote the recovery of frostbite and effectively prevent the recurrence or alleviation of the frostbite next year. If the frostbite is not broken, you can add a few dried chilies. It is best to use the pot and towel separately. The boiled water does not need to be replaced, but it must be boiled every time. When adding new water, the boiling time must be extended.

3. Pickling: Here are the methods

Peel off the outer skin, making sure to peel off all the green skin, otherwise it will taste bitter. Then cut it into thin strips horizontally. Boil it in boiling water, then soak it in cold water for a day or two, changing the water once or twice. When changing the water, make sure to squeeze out the moisture from the skin first, then put it in new water (this will remove the bitterness).

After one or two days, squeeze out the water from the skin, let it dry for a while, and set aside. Then boil some sugar until it becomes the same as water (if you want it spicy, you can add some sugar), and boil the skin for a while. This is how you make grapefruit candy.

4. Grapefruit "brew"

The method is similar to the above, except that the skin is cut into three or four pieces, forming a triangle, and then carefully cut a small hole in each piece with a knife to put the prepared stuffing in (the stuffing depends on everyone's taste, you can use the stuffing you usually use for stuffed tofu). Remember to boil it in boiling water, soak it in cold water for a day or two, squeeze out the water and then stuff it. Then cook it.

5. Cooking.

First, clean the grapefruit, peel off the green skin and remove the flocs. Leave the soft white sponge in the middle and cut it into thin slices. Then put the sliced ​​grapefruit peel into a pot and soak it in clean water for two to three days. Change the water every day to remove the bitter taste. If you are in a hurry to eat it, blanch the sliced ​​grapefruit peel in boiling water before putting it into the pot. Even if it is a freshly opened grapefruit, it can also remove the bitterness. Stir-fry shredded ginger, minced garlic, and dried chili in oil (a little more oil). After the aroma comes out, add dark soy sauce and pour in clean water. After the water boils, pour in the squeezed grapefruit peel, add salt, and fry after the water is dry.

6. Can prevent insects.

Tear off the white tendons inside, put it in a ventilated place to dry, and then dry it in the sun. Store it in a bag with small holes, which can be placed in the corner of the closet or in a rice bucket to prevent mosquitoes.

7. It can be placed in the room to remove odors.
