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.

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

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