Usually, taking menstrual regulating herbs will not lead to gaining weight. If there is a case of gaining two pounds in six days, it is mostly not a problem of taking menstrual regulating herbs. Herbs for menstrual regulation in women mainly have the effects of invigorating blood stasis, strengthening the spleen and dispelling dampness, tonifying the liver and kidney, draining the liver and Qi, and warming the menstruation and dispersing cold. Some menstrual regulating herbs such as yam, lotus seed and motherwort have the effect of strengthening the spleen and stomach and dispelling dampness, which can help to achieve weight loss. Although herbs do not cause obesity, many menstrual regulating herbs have a tonic effect, which can promote the absorption of the spleen and stomach, enhance digestive function and promote appetite, and if women do not pay attention to control their diet during taking herbs, it may lead to two pounds of weight gain in six days. For weight gain caused by increased diet and reduced exercise while taking menstrual regulating herbs, you need to adjust your diet structure, avoid eating oily foods and sweets, and eat more fresh fruits, vegetables and low-fat foods such as kiwi, oranges, tomatoes, corn and millet. You should also do outdoor activities such as running, jumping rope, playing badminton, etc., adjusting your work and rest schedule, reducing late nights and ensuring more than six hours of sleep.
