The neem tree, Azadirachta indica, provides seeds, leaves and other plant parts for different preparations. A cosmetic product, a plant protection product and an orally marketed extract are not interchangeable.
Clarify the product form first
| Form | Key question |
|---|---|

Limited studies do not establish a general treatment
Small studies have examined individual neem preparations, for example in oral hygiene or metabolism. Their results cannot be transferred to every oil or capsule. Laboratory findings against tumour cells in particular do not prove a cancer treatment in humans.
Do not drink neem oil as a home remedy
Severe poisoning in children and adults has been reported after swallowing neem oil. Drowsiness, vomiting, visual disturbances or seizures after ingestion require immediate medical help. Do not wait to see whether another home remedy works.
Skin irritation and contact allergies are also possible with external use. Use only products intended for the purpose, following instructions, and stop if reactions occur. Do not repurpose technical preparations in homemade health treatments.
Frequently asked questions
Does natural automatically mean well tolerated?
No. Product form, route of exposure and individual circumstances determine that.
Are possible drug interactions established?
Not fully. Some findings come from laboratory experiments; their clinical significance is uncertain. Discuss medicines and extracts with a qualified professional beforehand.
