The health benefits and health value of longan

Longan, also known as longan, is a fruit with the same origin as medicine and food. It has the functions of nourishing the heart and spleen, nourishing blood, calming the nerves, and relieving fatigue. Its main value is reflected in improving Qi and blood deficiency, enhancing immunity, and anti-oxidation. It is suitable for people with weak constitution and insomnia. This article will analyze the health-preserving effects of longan from the perspective of traditional Chinese medicine theory and modern nutrition, and attach relevant products and data for reference.

1. Enrich blood and nourish skin, improve deficiency of Qi and blood

Longan is rich in iron, vitamin C and other ingredients, which can help promote hemoglobin synthesis and relieve anemia symptoms. Traditional Chinese medicine believes that it is warm in nature and sweet in taste, and it returns to the heart and spleen meridian, and has a conditioning effect on women who are weak or pale after childbirth. Modern research also shows that the polyphenols in longan can delay skin aging. For example, research from Fujian Agriculture and Forestry University pointed out that longan extract has antioxidant activity (source: "Food Science" journal).

2. Soothe the nerves, aid sleep, and relieve fatigue

Longan is rich in glucose and sucrose, which can quickly replenish energy and is suitable for mental workers. Its sedative effect is recorded in the "Compendium of Materia Medica" as "enhancing the mind and calming the mind", and it is often used clinically to improve insomnia and dreaminess. For example, the "Longan, Red Date and Wolfberry Tea" produced by Tongrentang combines this effect and has become a hot-selling product in the market.

3. Enhance immunity and regulate physical fitness

The polysaccharide component of longan can activate immune cells and improve disease resistance. Research by the Chinese Academy of Medical Sciences found that longan meat extract can significantly improve the immune function of mice (Source: "Chinese Journal of Traditional Chinese Medicine"). Dried longans launched by brands such as "Fangjiapuzi" on the market retain most of their nutritional ingredients and are easy to eat daily.
