Introduction
Rinse hands thoroughly under running water immediately, repeatedly washing to remove as much residual yam mucilage as possible and reducing the continued irritation caused by saponins and plant alkaloids. Rinse for no less than 1 minute. Then, pour a small amount of white vinegar into the palm, rub both hands together, and apply the vinegar to the itchy areas. The acidity of the vinegar helps neutralize the alkaline substances in the yam mucilage, thereby relieving itching.
Itching on the hands caused by handling Chinese yam should be addressed promptly by removing the irritant and relieving discomfort. This can usually be managed through methods such as rinsing with clean water, wiping with white vinegar, soaking in salt water, applying cooking oil, or using a cold compress. If symptoms persist or concerns arise, it is advisable to seek medical advice early. Detailed measures are as follows:
1. **Rinse with clean water**: Immediately rinse hands thoroughly under running water for at least one minute to wash away residual mucus from the yam, minimizing continued skin irritation caused by saponins and plant alkaloids.
2. **Wipe with white vinegar**: Pour a small amount of white vinegar into the palms, rub hands together, then apply to the itchy areas. The acidity of vinegar helps neutralize alkaline components in the yam’s mucus, reducing itching. Leave on for 3–5 minutes before rinsing off with water.
3. **Soak in salt water**: Dissolve a suitable amount of table salt in warm water and soak the affected hands for 10–15 minutes. Salt water helps reduce skin irritation and soothe itching. After soaking, dry the hands gently.
4. **Apply cooking oil**: Apply a small amount of edible oil or hand cream to the itchy area and gently massage to promote absorption. The oil forms a protective barrier against irritants and moisturizes the skin, helping relieve dryness and itching.
5. **Cold compress**: Wrap an ice pack or ice cubes in a towel and apply to the itchy area for 5–10 minutes. The cold helps constrict blood vessels, reducing redness, swelling, and itching. Avoid placing ice directly on the skin to prevent frostbite.
To prevent itching before handling Chinese yam, wear gloves while peeling or immediately soak the peeled yam in water. If itching persists, or if signs such as redness, swelling, or rashes develop, seek medical attention promptly. Avoid scratching to prevent skin damage and potential infection.
