The content of nuciferine in fresh lotus leaves is only one thousandth, and the content of flavonoids is 5%.

The lipid-lowering components of lotus leaf are nuciferine and flavone. Flavonoids have good water solubility and poor alkalinity. Simply from the perspective of taking effective weight-losing ingredients, you can cook lotus leaves with high-alcohol liquor (or medical alcohol) for one hour. At this time, the liquor should turn black, and the weight loss ingredients contained in it are much higher than those in lotus leaf water. When taking, the boiled white wine can be dried with lotus leaves and added to food. The daily dose seems to have never been tested pharmacologically. It depends on your own situation. As long as you don't have diarrhea, you can increase the dose.

Note that during the whole process, neither lotus leaf nor liquor can touch metal. You can cook lotus leaves in a casserole and hold white wine in a glass cup.
