Eating yam is good for stomach ulcers. Yam, also known as Dioscorea and Huaiyam, is a traditional Chinese medicine with a sweet and flat taste, entering the lung and spleen meridians. There are many kinds of yams available in the market, some with smooth skin and crispy taste, which can be fried and eaten. Some yams have uneven skin, many pockmarks, hairy beards, and a strong texture, making them suitable for soup and congee. Some ancient Chinese herbal formulas for strengthening the spleen also include yam, such as Ginseng Ling Bai Zhu San, Liu Wei Di Huang Wan, Zuo Gui Wan and Right Gui Wan. Yam is mainly used in the formula to strengthen the spleen and has a weaker role in tonifying the kidneys, so eating yam is good for stomach ulcers, but eating yam is a dietary treatment and medicinal meal and cannot replace medication.
