Origanum vulgare
Oregano
This plant is native to Europe, the Mediterranean and southern Asia. It has tiny hair like glands on its surface called trichomes which reflect the intense rays of the sun. This is a trait common to most plants in the Lamiaceae or Mint family. The trichomes synthesize and accumulate essential oils and phenols which protect the plant from oxidation while allowing it to survive in dry and hot conditions with direct exposure to intense sunlight. Throughout history, Oregano was used primarily as a culinary spice in gardens. It was used to preserve meat in ancient times before refrigeration was available, as were other spices which contain high amounts of volatile oils like Thyme (Thymus vulgaris) and Rosemary (Rosmarinus off.).
