Senna leaves can achieve a certain curative effect in a short term, but it will have side effects in a long term, that is, it will cause constipation. Senna leaves are not suitable for long-term use. I suggest you change your dressing. You can also eat more crude fiber foods such as sweet potatoes and celery, which is beneficial to intestinal health. However, health is the most important thing. I advise you not to use drugs indiscriminately.
