What are Lotus Seeds?
Lotus seeds, also known as lotus hearts or “lian xin,” are scientifically referred to as Embryo Nelumbinis. They are the green germ found within the lotus seed. The most notable effects of lotus seeds include calming the mind and clearing heat.
The lotus is a flowering aquatic plant with a cylindrical rhizome that grows deep into the mud, known as lotus stems. The lotus leaves are round, approximately 60 cm in diameter, with a deep center and long stalks that rise above the water’s surface. In Traditional Chinese Medicine, the leaves are called “lian ye” and are used for medicinal purposes.
Lotus flowers have many overlapping petals, which can be white or pink. When they first bloom, the petals close around the flower bud, then open wide. The fruit contains numerous seeds known as “lian ru.” The outer layer of the lotus seed is covered in a smooth green shell, while the inner seed is white and divided into two parts, revealing the germ known as the lotus heart.
Traditional healer Bui Hong Minh, president of the Ba Dinh Traditional Medicine Association, shares: “Lotus seeds are bitter, cooling, and enter the heart meridian, providing functions to clear heart heat, calm the spirit, induce sleep, and lower blood pressure. They help clear heat and are used for conditions of internal heat, anxiety, insomnia, and hypertension.”
