Chinese medicine rhubarb is bitter and cold in nature, and has the effect of purgation. It mainly contains anthraquinone derivatives. After taking it, it gradually decomposes in the intestine to produce anthrone which stimulates the large intestine and promotes peristalsis of the large intestine, thus causing diarrhea. There is no food in the intestines of newborns at birth, so diarrhea can damage the gastrointestinal mucosa of newborns. The Six God Pills contain bufadienolides, whose main function is to treat abscesses and sore throat. Large amounts can damage eyesight, and overdoses can cause arrhythmia and even poisoning leading to death, so they should not be taken indiscriminately. When a newborn is born, all functions of the internal organs are in the initial stage of start-up and are relatively fragile. Therefore, as long as everything is normal when a newborn is born, there is no need to take these "first mouth tea" to avoid counterproductive results.
