Introduction
Under normal circumstances, Chinese yam (Huai shan) has certain auxiliary effects in improving qi deficiency, but it cannot directly treat qi deficiency. It should be consumed in moderation and combined with other regulatory methods. In daily life, improving qi deficiency should involve regular作息 (作息 should be translated as "rest and作息" or "rest and activity patterns"), moderate exercise, and a balanced diet including ingredients such as red dates and astragalus. Relying solely on Chinese yam has limited effects; comprehensive regulation is necessary for better improvement of qi deficiency.

Generally speaking, Chinese yam (Huai Shan) has certain auxiliary benefits for improving qi deficiency, but it cannot directly treat qi deficiency. It should be consumed in moderation and combined with other regulating methods. Details are as follows:

Chinese yam is a commonly used ingredient in both culinary and medicinal contexts, rich in mucilaginous protein, starch, B-complex vitamins, and various minerals. According to traditional understanding, Chinese yam can strengthen the spleen and stomach, promoting digestive health. Since the spleen and stomach are the foundation for generating qi and blood, improved digestive function helps the body absorb nutrients more effectively and produce qi and blood, thereby assisting in alleviating symptoms associated with qi deficiency, such as fatigue and lethargy. However, Chinese yam is not specifically intended to treat qi deficiency. Overconsumption may lead to excessive starch intake, increasing digestive burden and potentially causing discomfort such as bloating. Therefore, it is recommended to prepare Chinese yam using mild cooking methods such as steaming or boiling, and to control the portion size appropriately.

In daily life, improving qi deficiency should involve maintaining regular sleep patterns, engaging in moderate exercise, and following a balanced diet that includes other ingredients such as red dates and astragalus root. Relying solely on Chinese yam will have limited effects; comprehensive regulation is necessary for effectively improving qi deficiency.
