What is lotus leaf? What is it used for?
Lotus node comes from the lotus, a perennial aquatic plant related to the water lily. It grows throughout the tropical regions of Asia and the Middle East, with light green leaves and vibrant white flowers.
The leaves can grow extremely large at times, reaching more than 18 inches in diameter. They are typically collected in the summer and autumn, cleaned, then dried in the sun and cut into small pieces.
Based on the concepts of traditional Chinese medicine, lotus leaf is slightly bitter, and mild, and is attributed to the Liver and Spleen meridians. The main functions of lotus leaf are to stop bleeding and invigorate the blood. As with most other parts of the lotus, lotus leaf is employed to treat a variety of conditions, ranging from hematemesis (vomiting with blood) and hematuria (blood in the urine) to metorrhagia and diarrhea. An active ingredient in lotus leaf, nuciferine, also helps to reduce muscle spasms. In addition, lotus leaf is sometimes used to treat dizziness and fevers.
