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.
