Overview of the efficacy and functions of lotus seed heart

Lotus seed heart is the green germ of lotus seeds. Traditional Chinese medicine believes that it has the effects of clearing away heat and reducing fire, calming the nerves, promoting sleep, and lowering blood pressure. Modern research also shows that lotus seed hearts are rich in active ingredients such as alkaloids and flavonoids, which have certain regulatory effects on the cardiovascular and nervous systems. This article will start with its core functions, applicable groups, usage methods and precautions to help readers scientifically understand the value of lotus seed heart.

Core function one: clear away heat and reduce fire, relieve discomfort due to heat

Lotus seeds are cold in nature and bitter in taste. Traditional Chinese medicine is often used for symptoms such as sores in the mouth and tongue, irritability and insomnia caused by excessive heart fire. In summer, soaking lotus seeds in water instead of tea can help relieve dry mouth and tongue caused by heat. Research shows that the liansinine contained in it has a slight antibacterial effect, but it should be noted that people with weak constitution should not take it for a long time.

Core Function 2: Soothe the mind, aid sleep, and regulate the nervous system

The alkaloid components in lotus seeds may improve sleep by inhibiting central nervous system excitability. "Chinese Materia Medica" records that its compatibility with Ziziphus Seed can enhance the calming effect. However, those with severe insomnia need to seek medical treatment and cannot rely entirely on dietary therapy. Daily, you can brew 3-5 grams of lotus seed hearts with honey and drink it one hour before going to bed.

Precautions and scientific usage suggestions

Lotus seed heart should not be taken excessively. The recommended daily dosage is 2-5 grams. Pregnant women, people with low blood pressure and those with spleen and stomach deficiency should use with caution. Commercially available products must be purchased from regular manufacturers, such as Beijing Tongrentang’s “Lianxin Qinghuo Tea” and Yunnan Baiyao’s “Lotus Seed Heart Powder”.
