Rosemary leaf is an herb native to the Mediterranean but is common in many parts of the world.
It is a member of the mint family Lamiaceae, along with many other herbs, such as oregano, thyme, basil, and lavender.
Often used in cooking, it is also widely used in aromatherapy and medicine.
Here are some of its benefits.
1. Antioxidants and anti-inflammatory compounds
Rosemary contains compounds that may have anti-inflammatory and antimicrobial properties.
The antioxidant and anti-inflammatory activity of rosemary is largely attributed to its polyphenolic compounds like rosmarinic acid and carnosic acid.
The compounds in rosemary tea may also have antimicrobial properties, which may help fight infections, particularly by inhibiting the growth of certain bacteria and fungi.
