Rosemary is an ingredient that adds a fragrant savory note to dishes. Some people claim that rosemary can help reduce muscle pain, boost the immune system, and improve memory. However, it can interact with some medications.
Rosemary is a fragrant evergreen herb native to the Mediterranean. It is used as a culinary condiment, to make bodily perfumes, and for its potential health benefits. It is a member of the mint family Lamiaceae, along with many other herbs, such as oregano, thyme, basil, and lavender.
The herb not only tastes good in culinary dishes, such as rosemary chicken and lamb, but it is also a good source of iron, calcium, and vitamin B-6.
It is typically prepared as a whole dried herb or a dried powdered extract, while teas and liquid extracts are made from fresh or dried leaves.
The herb has been hailed since ancient times for its medicinal properties. Rosemary was traditionally used to help alleviate muscle pain, improve memory, boost the immune and circulatory system, and promote hair growth.

Rosemary has a range of possible health benefits.
Rosemary is a rich source of antioxidants and anti-inflammatory compounds, which are thought to help boost the immune system and improve blood circulation.

In Europe, rosemary is often used to help treat indigestion. In fact, Germany’s Commission E has approved rosemary for the treatment of indigestion. However, it should be noted that there is currently no meaningful scientific evidence to support this claim.
According to research outlined in Therapeutic Advances in Psychopharmacology, the aroma from rosemary can improve a person’s concentration, performance, speed, and accuracy and, to a lesser extent, their mood.

Another study, published in Bioscience, Biotechnology and Biochemistry, concluded that rosemary might be useful as an anti-inflammatory and anti-tumor agent.
Also, a report published in the Journal of Food Science revealed that adding rosemary extract to ground beef reduces the formation of cancer-causing agents that can develop during cooking.
A study published in the journal Investigative Ophthalmology & Visual Science, led by Dr. Stuart A. Lipton, Ph.D. and colleagues at Sanford-Burnham Medical Research Institute, revealed that a carnosic acid, which is a major component of rosemary, can significantly promote eye health.
This could have clinical applications for diseases affecting the outer retina, such as age-related macular degeneration – the most common eye disease in the United States.
