Vervain is not a poisonous plant and its potential toxicity is mainly due to misuse or higher doses than the recommended.

The essential oil is neurotoxic and convulsive, because of verbenalin, which can eventually cause nerve paralysis and seizures.

On the ground, verbenalin (glucoside) is most abundant in the flowering tops of the plant. This component disappears during drying.

At high doses the plant can be vomitive.

It is worth noting that the plant has significant side effects, especially those related to pregnancy. Verbena has been for years a plant to accelerate childbirth, so, it should not be taken during pregnancy. It can cause abortion by its oxytocic effect or uterine stimulant.

Its effect is due to the action of the iridoid glycosides to bind to dopamine receptors, which stimulate the production of luteinizing hormone. Luteinizing hormone (LH) is produced by pituitary gland in the brain and has the function to induce ovulation in women and androgen production or testosterone in men.

For its uterine stimulant effect, women with endometriosis or menorrhagia (excessive vaginal bleeding) should not take it.
