Herbs and Spices


Herbs are generally aromatic leaves, or sometimes seeds, from plants of temperate origins, whereas spices are aromatic fruits, flowers, bark, or other plant parts of tropical origin. Aromatic Plants have scents due to Essential Oils which are volatile substances that contribute to the essence or aroma of certain species. Essential Oils are most often terpenes which are a large group of unsaturated hydrocarbons with a common building block of C5H8 (isoprene molecule). Essential Oils play the role of attracting pollinators especially in the case of flowers, in the case of other plant parts scientists believe that they discourage herbivores and insects from eating them and inhibiting bacterial and fungal pathogens. Scientists have found that although herbs and spices may have been discovered because of their flavor and scent, they have remained integral parts of our lives to this day for their antimicrobial properties. Many herbs and spices especially onions, garlic, allspice, and oregano inhibit or kill many food-borne bacteria. Researchers suggest that food preservation may have been the main reason why spices were incorporated into the human diet as more spices were used in hotter climates where food spoilage is increased.

History of Spices


Ancient Egyptians used herbs and spices extensively in medicine, cooking, embalming, and as perfumes and incense. Ebers Papyrus, dated about 3,500 years ago, is a scroll that lists the medical uses of many plants and includes anise, caraway, mustard, saffron, and many other familiar herbs and spices. Cinnamon and cassia are also mentioned in Egyptian records, and because these two spices are native to Southeast Asia and China, evidence of an active spice trade exists

Herbs


In recent years there has been a renaissance in the use of herbs in everyday life, going beyond the kitchen to find applications in shampoos, cosmetics, soaps, potpourris, and medicines. Herbs are usually the aromatic leaves or sometimes seeds of temperate plants; however, other plant organs are sometimes considered herbs as well.

Four well-known herb families:
  • The Aromatic Mint (Peppermint)
  • The Parsley Family (Cilantro)
