If you experience itching on your hands after handling yam, or 山药 (shān yào) in Chinese, it could be due to the sap of the yam, which contains compounds that can irritate the skin. Here are some steps to alleviate the itching:
1. Wash Your Hands: Thoroughly wash your hands with soap and water to remove any residue from the yam sap.
2. Apply Cold Compress: Applying a cold compress or ice pack to the affected area can help reduce itching and inflammation.
3. Use Baking Soda: Mix baking soda with water to form a paste and apply it to the itchy areas. Baking soda can help neutralize the irritants in the yam sap.
4. Vinegar Rinse: Soak your hands in a mixture of vinegar and water for a few minutes. Vinegar can help counteract the alkaline compounds in the yam sap that cause itching.
5. Antihistamine Cream: Applying an over-the-counter antihistamine cream to the affected area can help relieve itching.
6. Avoid Scratching: Try to resist the urge to scratch the itchy areas, as this can further irritate the skin and potentially lead to infection.
If the itching persists or is severe, it may be necessary to consult with a healthcare professional for further evaluation and treatment. They can provide guidance on the most appropriate course of action based on the severity of the skin reaction.
