However, care should be taken when using it in the following cases: 1. Pregnant women and infants are prohibited. Camphor is the main component of anthralin, which has been found to have certain reproductive toxicity and developmental toxicity in animal experiments, and has obvious damage to the kidneys at high concentrations [1]. In particular, if anthocyanin is used in large quantities and frequently during the first 3 months of pregnancy, camphor will enter the amniotic cavity through the placental barrier and act on the fetus, which may lead to fetal death and abortion in severe cases. The newborn’s delicate skin and mucous membranes can also be infiltrated into the bloodstream by the action of anthocyanin, causing red blood cells to rupture and dissolve into bilirubin, resulting in neonatal jaundice. 2, skin damage is prohibited.
