Why can Senna achieve the effect of losing weight? Mainly because it can effectively promote the peristalsis process of human intestine and achieve the effect of diuresis and laxative. Imagine that human urine and feces garbage toxins are excreted. Does it mean that the whole person can get thinner slowly? According to Bian Xiao, some people have a lot of water in their bodies, and the content of garbage toxins in their intestines is also relatively high, which will make the whole person look extremely bloated and swollen. Insisting on drinking senna leaves can alleviate this situation to some extent, but it needs to be reminded that it is difficult to lose weight simply by ingesting senna leaves. Although effective, it takes a long time to be effective. It may take more than half a year to see a little thinner. The above is Bian Xiao's answer to the topic that Senna leaves are useful for losing weight. It should be emphasized and reminded that although Senna leaves have certain weight-reducing effect, if the gastrointestinal condition is not good, it is not recommended that you take Senna leaves to lose weight, otherwise it is likely to cause more serious diarrhea.
