Rosmarinus officinalis

Rosemary (Rosmarinus officinalis) is an ash-colored evergreen shrub which has a pungent, pinelike fragrance. It produces small pale blue flowers that grow in short axillary racemes. Rosemary is a common medicinal plant, known for its distinctive aroma and use in culinary dishes. The leaves from the rosemary plant are used for tinctures and infusions developed for traditional medicine as a treatment for rheumatism, gout, wounds, mouth inflammation and other health problems.

Adding rosemary to chickens' feed at 500ppm showed some benefit to chickens suffering from aflatoxicosis due to ingestion of toxic aflatoxins in their feed.

Rosemary is a woody herb with a slight piney and tea-like aroma.
