Windex is mainly composed of menthol, eucalyptus oil, clove powder, camphor, essential oils and so on, which is a necessary medicine for home and traveling in summer. However, people should pay attention to the following contraindications when using essential oil: Pregnant women are prohibited Camphor, one of the main components of essential oil, has a certain toxic effect. After camphor enters the human body, the glucose phosphate dehydrogenase in the normal human body will combine with it very quickly to make it become a non-toxic substance, and then discharged with the urine, so there will be no adverse reactions. However, due to physiological changes, the glucose phosphate dehydrogenase content in the body of pregnant women decreases, especially in the first three months of pregnancy, if too much use of essential oils, camphor will be absorbed through the skin into the body, and then through the placental barrier to enter the amniotic cavity of the fetus, which can lead to the death of the fetus and cause abortion in severe cases. Maternity and infants are prohibited The body of newborn babies also lacks glucose phosphate dehydrogenase, if mothers use a lot of anemone, camphor will penetrate into the blood through the delicate skin and mucous membrane of newborn babies along with the smell, which will make the red blood cells rupture and dissolve into bilirubin.
