It has the functions of detoxifying and eliminating carbuncle, moistening intestines and relaxing bowels. But Polygonum multiflorum can't soak in water. Polygonum multiflorum Thunb is poisonous. Ancient books thought it was non-toxic, but modern research found that Polygonum multiflorum Thunb has nephrotoxicity, which can cause liver and kidney damage and must be used correctly.

2. First of all, raw Polygonum multiflorum should not be used, but prepared Polygonum multiflorum should be used, and the dose should not be large. When taking medicine, don't look at Polygonum multiflorum Thunb. Sometimes it is used together with other drugs, and the drugs are restrained. Therefore, the toxicity of Polygonum multiflorum Thunb. in compound preparations is not obvious, so it may not be necessary to use it alone.

3. So you can't drink Polygonum multiflorum Thunb. every day, and you will have symptoms of poisoning, which is unacceptable. Drug abuse must be targeted and have an accurate plan. You can't take drugs indiscriminately every day.
