The essential oils are very powerful and can generate more or less embarrassing side effects, if handled carelessly. This is why health practitioners often highlight a possible danger in the context of improper use, since a toxic threshold exists and should not be exceeded. You should know that it only takes 1 g of lavender to become drowsy, 2 g of hyssop to risk an epileptic attack, and 2 tbsp. coffee EO of sage to put the consumer’s life in danger. An essential oil contains nearly 200 different components that can act quickly throughout the body. They should therefore never be used haphazardly, without the advice of a health professional.
