The reason why yam can cause itchy skin is that the mucus of yam contains phytoalkaloids, while saponin exists on the skin of yam, which will cause skin sensitivity. Originally, these two are allergens. For people with allergies, as long as they come into contact with yam, they will be allergic, so it is safer to wear gloves when handling yam. Originally, yam mucus is uncomfortable to stick to the skin, so wearing gloves will be more hygienic and safe.

Be careful when handling yam. Put on gloves first, then clean the yam skin. Boil the yam with a pot of hot water first, and then you can tear off the skin directly. Moreover, the allergic substances between the yam skin and yam mucus cooked in hot water will also be denatured and destroyed, so there will be no allergic itching when the yam skin is treated again at this time.

In addition, when cooking yam, the time can't be too long, usually five minutes. You can cut a knife on yam in advance, so it will be easy to peel off after boiling. After handling yam, remember to wash your hands thoroughly. Simply wash your hands with soap. If possible, you can sprinkle a little white wine on your hands, and then wait for the white wine to evaporate naturally, so that you won't worry about allergies even if you get the mountain liquid medicine on your hands.

In case of skin itching caused by improper handling, you can choose ginger to relieve itching at this time. After slicing ginger, smear it back and forth on the itchy part, which can promote blood circulation. After all, saponin is quickly decomposed, so it will not continue to be red, swollen and itchy. Of course, if you have been allergic when handling yam, it is best not to touch yam again.

Therefore, allergy is actually a very dangerous behavior. If a single allergic reaction is serious, it is likely to cause suffocation and hypoxia, and even life-threatening if it is serious. Therefore, it is safer to use other ingredients instead.
