Is aloe poisonous? Please tell me about its efficacy.

Aloe vera used to be thought to have a cosmetic effect, but it is actually an external herbal medicine, not an edible food. In recent years, aloe is considered to have anti-inflammatory and bactericidal effects, so it is advocated to list aloe as a healthy food with cosmetic and external use functions. The so-called fresh aloe powder and fresh aloe juice are very popular with consumers. Because emodin contained in aloe skin will cause diarrhea, some people regard it as a holy product to lose weight. It should be noted that, according to an animal study done by the medical community, mice taking aloe vera for a long time, especially emodin in aloe vera skin, will cause gastric cancer. Therefore, it is recommended to eat aloe peel. At present, there is no strict human experimental research report on edible aloe in China. It is suggested that fresh aloe should not be taken for a long time and should never be taken in excess. At the same time, young children and pregnant women should be prohibited from taking fresh aloe vera to avoid adverse consequences.
