Understanding Neem Oil Exposure Risks and Symptoms
While generally recognized as safe when used appropriately, neem oil does require respect and proper handling to avoid adverse effects. The eyes are particularly vulnerable; splashes can cause significant pain, redness, and corneal damage, necessitating immediate flushing with water and medical consultation if exposure occurs.
Ingestion of the pure, concentrated product poses the most significant threat and can cause nausea, vomiting, and damage to the liver and kidneys. Inhalation of neem oil aerosols, particularly during agricultural spraying or heating, may irritate the respiratory tract and lungs, making ventilation a critical factor in any application.
Understanding Inhalation, Skin Contact, and Ingestion Risks
Understanding that azadirachtin targets the nervous system of insects helps explain why it demands careful handling for mammals, including humans. However, this data does not negate the importance of keeping products away from children and pets, as their smaller body size increases susceptibility to the toxic effects of ingestion.
