Although lavender oil does have some good healing properties and is good for a lot of things including insomnia, lavender oil can have some side effects especially with young boys.
The side effects of lavender oil include possible breast growth in boys and interactions with other medicines.
The side effects mostly happen to young boys and don't affect older men or woman as much so you shouldn't have to worry when using lavender oil since the many benefits of lavender oil use outweigh any side effects that may happen as the result of lavender oil use.
