Porridge oil, also known as "rice oil" in traditional Chinese medicine, is a thin, sticky layer that forms on top of well-cooked porridge. While many people overlook it, this substance is actually highly nutritious and considered comparable to nourishing broths. It's commonly derived from millet or rice and has been valued for centuries for its health benefits. According to ancient medical texts, both millet and rice are believed to be sweet and neutral in nature, helping to strengthen the spleen and stomach, and replenish qi. When cooked into porridge, a significant portion of the nutrients transfer into the broth, with the oily layer being particularly rich in essence. Some sources even suggest that rice oil is as potent as ginseng or rehmannia in terms of nourishment. In *Supplement to the Compendium of Materia Medica* by Zhao Xuemin of the Qing Dynasty, it was noted that consuming rice oil daily for 100 days could improve the condition of weak individuals, making their skin fairer and their bodies stronger. It was said to be more effective than rehmannia in nourishing yin. Similarly, the Qing physician Wang Mengying mentioned in his book *Residential Diet* that rice oil could serve as a substitute for soup, offering similar benefits to ginseng. Traditional Chinese medicine emphasizes that after the age of 50, many people experience kidney deficiency. Drinking porridge oil can help replenish kidney essence and promote longevity. For those suffering from chronic gastrointestinal issues, especially women who often feel weak and fatigued, porridge oil can restore vitality, increase energy, and support faster recovery. The best time to consume porridge oil is on an empty stomach, and adding a small amount of salt can enhance its kidney-nourishing effects. According to *Zilin Shanfang*, this method may also help men with sexual dysfunction. Additionally, porridge oil is an excellent choice for infants and young children when they begin to introduce solid foods. To make high-quality porridge oil, it's important to use a clean, oil-free pot and cook the porridge over low heat without any seasoning. Studies have shown that rice oil made from fresh rice can protect the gastric mucosa, making it ideal for those with chronic gastritis or ulcers. However, using old rice may lead to irritation and even ulcers. Therefore, only high-quality, fresh rice should be used to ensure the full nutritional benefits of the porridge oil.
