    1. Essential aromatics from plants

    4. Terminology Secondary plant products not critical for metabolism Essential oils volatile chemical compounds used in aromatherapy Herbs (botanical vs culinary) Spices (usually tropical) Perfumes later

    5. Why did humans start using herbs and spices? Word “spice” has the same root as species, meant small products Evidence is that people started using spices all over the world By the mid-1300’s a Florence merchant listed 200 “spices” in his catalog

    6. Why did humans start using herbs and spices? Did people use spices because of antimicrobial activity?

    7. Some spices have antimicrobial activity

    8. Ancient methods of food preservation Drying Freezing Curing (salt, etc.) Smoking (evidence from Ireland 2000 BC) Pickling Fermentation processes

    9. Spices as preservatives Unlikely that the expensive spices (pepper, cloves, etc.) were ever used this way Onion and garlic—maybe thiosulfonates

    10. Correlation between number of spices in recipes and average temperature Data from Paul Sherman, Cornell, March 1998 issue of the journal Quarterly Review of Biology. Why?

    11. Wondering about spices… Pliny the Elder, in Natural History around 79 AD, says that "Long pepper ... is fifteen denarii per pound, while that of white pepper is seven, and of black, four." Pliny also complains "there is no year in which India does not drain the Roman Empire of fifty million sesterces."

    12. More from Pliny the Elder It is quite surprising that the use of pepper has come so much into fashion, seeing that in other substances which we use, it is sometimes their sweetness, and sometimes their appearance that has attracted our notice; whereas, pepper has nothing in it that can plead as a recommendation to either fruit or berry, its only desirable quality being a certain pungency; and yet it is for this that we import it all the way from India! Who was the first to make trial of it as an article of food? and who, I wonder, was the man that was not content to prepare himself by hunger only for the satisfying of a greedy appetite?[8]

    14. We always look to Europe… Peppers Found in prehistoric sites in Peru Thought first cultivated circa 6000 BC

    15. Egyptian use of spices Queen Hathepsut sent an expedition to East Africa in about 1500 BC to bring back 31 frankincense trees, myrrh (and myrrh trees), cinnamon, numerous varieties of other incenses, cosmetics and perfumes.

    18. Benzoin, flowers of Benjamin Styrax species Again it’s a gum from the plant Burned as incense, also medicinal

    19. Egyptian Embalming Religious motivations preserve the body for the return of the soul two peppercorns were inserted in the nostrils of the mummy of Ramses II in 1224BC Mostly about drying and sodium bicarbonate

    21. Earliest uses of spices One of the earliest documented records of spices is in the 1550 B.C. medical document "Ebers Papyrus" which stated that anise, cassia, cardamom, mustard and other aromatics were used by Egyptians. Kyphi—recipe for incense, said to be found here

    24. Recipe for an asthma treatment involving several herbs heated on a brick Aromatherapy!

    25. Coriander Cilantro and Chinese Parsley Same family as anise Possible fruits from Israel, about 6000 BC Described in Sanskrit writings from India Egypt

    27. Romans spread spices into Europe Europe-Asia trade left with the fall of the empire, 476 AD Dark ages--Europe mostly uses herbs Marco Polo--25 yrs in orient, wrote about it

    28. Venice Dominates Spice Trade Middle Ages in Europe Spices extremely valuable a pound of ginger was worth the price of a sheep a pound of mace would buy three sheep or half cow cloves cost the equivalent of about $20 a pound many towns kept their accounts in pepper; taxes and rents were assessed and paid in this spice and a sack of. pepper was worth a man's life. Overland route; the sea routes were disrupted by Turks, others
