Neem comes from the tree Azadirachta indica. Leaf powder, bark, extracts and seed oil are different products. Neither traditional use nor the word “natural” proves that every form is suitable for ingestion or skin use.
Limited clinical evidence
Small studies of particular neem preparations have examined oral health or metabolic measurements, for example. Such findings do not automatically apply to loose leaf powder, every dose or other diseases. Laboratory results do not prove that neem reliably treats cancer, infections or parasites in people.
Particular risks when swallowed
Severe poisoning after swallowing neem oil has been described in children and adults, including vomiting and neurological disorders. These reports concern a particular product form: they prove neither identical toxicity of every leaf powder nor the safety of other neem products. Do not use these differences to work out your own supposedly safe oral dose.
Topical use is not automatically well tolerated either
Neem products can cause skin contact reactions. Use products only for their explicitly stated purpose and pause if a reaction occurs. Have use assessed beforehand by a healthcare professional in the case of medicines, medical conditions, pregnancy, breastfeeding or children. Do not use neem on your own as a substitute for necessary treatment.
After accidental ingestion of an unsuitable product or suspected poisoning, immediately contact a poison information service or medical help and keep the packaging available. Seizures, impaired consciousness or severe acute symptoms require immediate emergency help.
