Inhalation of large quantities of floral water can generally lead to allergies, respiratory system, nervous system and other hazards. Flower water has the effect of repelling mosquitoes and itching, deodorizing and sterilizing, etc. However, the composition of flower water is relatively complex, and inhaling a large amount of flower water can cause some harm to the body. 1. Allergy: Flower water contains a component called imogenin, which is highly irritating and can cause an allergic reaction after inhaling too much, while alcohol and some flavorings may make individual patients allergic. 2. Harm to the respiratory system: Inhaling a large amount of perfumed components of floral water can cause sneezing, runny nose, coughing and other respiratory symptoms. 3. Harm to the nervous system: the alcohol concentration in eau de toilette is very high, and inhalation of large quantities can lead to dizziness, headache and other discomforts. When more serious symptoms occur after inhaling large quantities of floral water, it is important to seek medical attention in a timely manner to avoid serious consequences.
