Why does yam make people allergic?
Yam allergy, which is medically a contact dermatitis. Since not all people have this symptom when they come into contact with yam, it may also be an allergic reaction. At present, it is believed that the cause of this contact dermatitis is saponin contained in yam skin or alkaloids contained in the mucus. The pruritus appears when the skin contacts these two components.
However, not all people will have this reaction when they come into contact with raw yam. Therefore, this reaction may be an allergic reaction.
How can itch allergy relieve itching?
Wipe vinegar
To deal with the itching of yam allergy, you can use the long-kitchen condiment, which is vinegar. You can wash your hands with vinegar and water, you can also use sour lemon, sour and other sour fruit smashed hands to relieve itching. However, different people have different allergic reactions to yam, and washing vinegar with water is not a method for all people.
Fire grill
Another easy way to deal with allergies to yam is to directly put your hands on the fire and you can quickly relieve itching. But pay attention to safety, do not burn the skin.
Hot water bubbler
Heat source is a good way to make many substances lose their biological activity. Therefore, when the yam itches hands, put the hands in hot water for 5 minutes, it will not itch.
Reminder: If there are symptoms of yam allergies, it is important to avoid scratching everywhere. Otherwise, the degree of pruritus will continue to expand. This is because allergens have spread and allergic symptoms will expand. If itching is elsewhere, it's best to scratch with scratchers or other items.
How to prevent irritability
After cleaning the yam skin, it is best to wear a pair of gloves or put a plastic bag on the hand and then peel it. If wearing a pair of gloves is inconvenient, you should prepare a pot of boiling water. After washing the yam, directly put it in water and cook it. In this way, the yam skin is basically cooked, the original allergens are destroyed, and they will not be allergic after re-contact.
Moreover, after the yam has opened, it is easy to remove the skin by using a kitchen knife to gently stroke it from top to bottom. But be careful not to cook too long, and it's best to cook the whole root, not cut.
In addition, people who have experienced pruritus on contact with yam should avoid direct skin contact with yam; if the skin is dry and there is chapped or damaged skin, it is more prone to tingling reactions and to avoid contact. Finally, remind that the kind of mucus is very nutritious ("juice more liquid sticky" is a good yam). If done well, you will not lose more nutrients.
If you do not touch the skin carelessly, if you have allergies, do not rub it around. This can cause itchiness in other areas, scratching the skin, and even more trouble. If it's really itchy, try putting it on the rice and rubbing it again and again to relieve itching. (From "Knowledge Is Power" magazine Kang Huonan)
