Can lotus seeds regulate irregular menstruation?
Generally speaking, lotus seeds can help regulate irregular menstruation, but they should be consumed in moderation. Detailed explanation is as follows:

Lotus seeds have a sweet and astringent taste with a neutral nature, and are associated with the spleen, kidney, and heart meridians. They have functions of strengthening the spleen to stop diarrhea, reducing vaginal discharge, benefiting the kidneys to arrest seminal emission, and nourishing the heart to calm the mind. For irregular menstruation caused by deficiency of both the spleen and kidney, insufficient qi and blood, or mental restlessness—such as prolonged menstrual periods, excessive or scanty menstrual flow, fatigue, and insomnia accompanying menstruation—eating lotus seeds in moderation can help regulate the body's internal blood and organ functions, thereby improving menstrual conditions to a certain extent. Moreover, lotus seeds contain nutrients such as protein, fat, carbohydrates, calcium, phosphorus, and iron, which can provide nutritional support and enhance physical health, indirectly contributing to the normal functioning of the menstrual cycle.
The effect of lotus seeds in regulating irregular menstruation is limited and cannot replace medical treatment. If symptoms of menstrual irregularity are severe or persist for a long time, timely medical consultation and examination are necessary. Additionally, lotus seeds have a binding effect and can relieve diarrhea; therefore, individuals suffering from constipation should avoid consuming excessive amounts to prevent worsening of constipation. Furthermore, lotus seeds should be thoroughly cooked before consumption, and raw consumption should be avoided to prevent gastrointestinal discomfort.
