Lotus seed heart is the green embryo root of the mature seed of the Nymphaeaceae plant, Lotus. It has an extremely bitter taste, is cold in nature, and belongs to the heart and kidney meridians. The core efficacy lies in clearing heart fire and calming liver Yang. It can effectively alleviate irritability, insomnia, mouth ulcers caused by excessive heart fire, as well as red eyes and dizziness resulting from liver fire ascending. Modern research shows that the alkaloids and other components it contains also have the effect of lowering blood pressure and calming the mind. However, its cold and severe nature can easily harm the Yang qi of the spleen and stomach. Therefore, those with weak spleen and stomach, poor appetite and loose stools should use it with caution. Ordinary people should also avoid taking it in excessive amounts for a long time to prevent discomfort.
