Rosemary has been used for centuries as a folkloric remedy to treat skin irritations.
Several in vitro and in vivo studies have shown the skin healing and skin protective actions of rosemary extracts. Further, it has shown antimicrobial and antioxidant activities and maybe a helpful skin antiseptic. More research is warranted to demonstrate this plant can be helpful in treating dermatitis, skin elasticity, would healing, photodamage, acne, and other skin infections.

How to Use Rosemary Topically for Skin Irritations
Here are three ways to use rosemary on the skin. Dilute and use as in anti-inflammatory, antiseptic, and skin protective recipes. Skin patch test. Avoid on damaged or sensitive skin. Not for internal use. Avoid with epilepsy, chronic asthma, and hypertension. Avoid during pregnancy and lactation. Not for use with young children.
- Add about 12 drops of rosemary essential oil to one ounce of a carrier oil such as coconut. Mix well and apply to skin in local area.
- Make a rosemary tea by pouring about eight ounces of hot water onto 2 Tbsp of fresh or 1 Tbsp of the dried herb. Strain, then soak a cloth in the water and apply to a local area for 15 minutes.
- Make an oil infusion: Fill a clean mason jar with fresh clean herbs. Pour sweet almond oil over the herbs and seal. Let the jar set on a window sill for about two weeks, shake the jar about once a day. After two weeks, strain out the herbs using a funnel and coffee filter or cheesecloth. The remaining oil will last in a sealed container about six months as long as there are no contaminates in the oil.
