Since neem has the property of aborting nested eggs, it is strongly advised not to consume neem products if you are pregnant or wish to have children.
Even though this effect is not safe as a contraceptive method, it can still lead to abortions of pregnancy in some.
There is also evidence that neem can be toxic in high doses. The toxicity of neem has already been studied in rats and mice (24, 25, 26).
It is not known exactly how dangerous an overdose of neem really is for humans.
It is essential to pay attention to the stated dosage of neem products.
As a precaution, however, it is recommended not to exceed the stated daily dose when taking neem capsules or powder. Otherwise, nausea and vomiting could occur.
The highly concentrated neem oil is generally intended for external use and should not be swallowed due to the risk of overdose.
