It is also used for wound healing, in bath therapy (balneotherapy), and as an insect repellent.

ROSEMARY Side Effects & Safety
Rosemary is safe when consumed in amounts found in foods, and seems safe for most people when used as a medicine that is taken by mouth, applied to the skin, or inhaled as aromatherapy.
However, the undiluted oil is UNSAFE to take by mouth. Taking large amounts of rosemary can cause vomiting, uterine bleeding, kidney irritation, increased sun sensitivity, skin redness, and allergic reactions.

Rosemary might stimulate menstruation or affect the uterus, causing a miscarriage. Not enough is known about the safety of applying rosemary to the skin during pregnancy. If you are pregnant, it’s best to avoid rosemary in amounts larger than food amounts.
If you are breast-feeding, also steer clear of rosemary in medicinal amounts. Not enough is known about what effects it might have on the nursing infant.
