Each part has distinctive properties and applications and has been used for centuries in traditional medicine. Lotus seeds are known for their nourishing and calming effects. Lotus leaves are used to clear summer heat and promote weight management. Lotus rhizomes are valued for their cooling and blood-circulating properties.

Main Active Ingredients

Lotus seeds contain alkaloids, flavonoids, and polysaccharides, are responsible for nourishing the Spleen and Kidneys. Lotus leaves are rich in flavonoids and alkaloids that contribute to dispelling summer heat. Lotus rhizomes contain starch, fiber, and nutrients, supporting their use in promoting blood circulation and stopping bleeding. For example, the alkaloids in lotus seeds, such as liensinine, have been studied for their potential calming effects. Flavonoids in lotus leaves, such as quercetin, act as antioxidants.

Product Application Scenarios, Usage, and Dosage

Lotus seeds are often used to treat conditions, such as diarrhea, insomnia, and poor appetite. Lotus leaves are commonly used in summer to alleviate heat-related symptoms and to assist with weight loss. Lotus rhizomes are used to manage bleeding and improve blood circulation.

Introduction to the Source Plant, Distribution, and Growth Environment

Nelumbo nucifera, the source of the lotus plant, is an aquatic perennial native to Asia. The plant is cultivated in ponds and shallow lakes; known cultivated regions include China, India, and other Southeast Asian countries. The lotus plant thrives in warm, wet environments, requiring plenty of sunlight and nutrient-rich soil.

Harvesting, Processing, and Storage

Lotus seeds are typically harvested in the late summer or early fall, when the seed pods are mature. The seeds are then removed, dried, and often shelled before use.

All lotus parts should be stored in a cool, dry place, away from direct sunlight and moisture, to preserve their beneficial properties.
