Lotus seed is the seed of the plant lotus, which can also be called white lotus, lotus fruit, lotus rice and lotus meat. Most areas in China have production, with Ganzhou in Jiangxi and Jianning in Fujian as the best. People like to eat lotus seeds very much. So, how about eating lotus seeds often? What are the benefits? The ancients believed that eating lotus seeds could rejuvenate and live forever. This is a legend, of course, and it is not credible. However, lotus seeds do have the medicinal value of nourishing the heart and calming the nerves, strengthening the brain and improving intelligence, and eliminating fatigue, which has been recorded in ancient medical books. For example, the medicinal effects of lotus seeds are recorded in books such as Shennong Materia Medica, Herbal Supplement, Compendium of Materia Medica and Compendium of Materia Medica. Modern pharmacological research has also confirmed that lotus seeds have many functions such as sedation, heart strengthening and anti-aging, because lotus seeds are rich in nutrients. Lotus seed not only contains a lot of starch, but also contains β-sitosterol, alkaloids and rich minerals and vitamins such as calcium, phosphorus and iron. According to experts' research, every100g of lotus seeds contains 89 mg of calcium and 285 mg of phosphorus. Although potassium is less than 2. 1 mg, it is already the first of all animal and plant foods. Lotus seeds, as a health-care medicated diet, are generally not discarded. Lotus seed core is the turquoise germ in the center of lotus seed, which tastes bitter and has the effects of clearing away heat, solidifying essence, calming the nerves and strengthening the heart. Soaking 2 grams of lotus seed core in boiling water can treat dysphoria, unconsciousness, wet dream's nocturnal emission, hypertension, dizziness, palpitation and insomnia caused by high fever.
