Contact with new cultures changed the drinking, eating, recreational habits of Europeans From Asia came tea, from Africa (Arabia) coffee and from America (Holland) cacao While beer is the unrefined drink of primitive, happy people, distillation was learned from the Moors ( Al Cohol). With it came alcoholism, addiction; then smoking, tobacco, gold and syphilis from America. Crusading is a bad idea, isolationism is good. The 3 temptations of foreign lands: alcohol + coffee (moor), tea + opium (asian) + smoking (american) Medically active substances in Plants Although medical action of plants like Aloe was known already to Cleopatra. However, the reduction of the effect to one or a few substances adds to our understanding of larger connection Anthraquinones: contract gut muscle Rheum, Cassia senna, also important red pigments Aloe, Rhamnus Mucilage: protect sensitive mucous Ulmus, Linum usit., membranes in throat, stomach & guts Verbascum, Tussilago Anthocyanins: important pigments, Rubus, Vaccinium, UV protectants & antioxidants Vitus vinifera Flavonoids: antioxidants, UV protect, Fagopyrum (rutin), antioxidants anti-inflamm, capillaries Vacc. leaves, lemon p Tannins: antibacterial, antifeedants, Quercus, Vitus vin., bind with proteins & alkaloids Rhus, Acacia catechu Coumarins: Blood thinner (anticoag.), Apium grav., Gallium relaxant, furanoco are photosensitizers Mellilotus off., Ammi Glucosinolates: skin inflammants, Rhaphanus (reddish), increase cap.

When a polymer film is exposed to a gaseous vapor, some of the vapor gets into the film and causes the film to swell. The vapor-induced film swelling produces an increase in the electrical resistance of the film because the swelling decreases the number of connected pathways of the conducting component of the composite material. The detector films are made from an insulating organic polymer that swells plus an inorganic conductor such as carbon black, Au, Ag, etc .. The electrical resistance of the film is then read using simple, low power electronics. Arrays of chemically sensitive conducting polymer films. that individually respond with resistance changes to vapors can produce a distinguishable response patterns like mammalian olfactory senses flavors and fragrances Plant names referring to scent & taste Agathosmus = aromaticus = fragrans = odoratus = fragrant blandus = mild, pleasing citriodorus = lemon-scented deliciosus = delicious dulcis = sweet foetidus = evil-smelling glycyrrhizus = like licorice graveolens = heavy scented inodorus = scentless meliodorus = honey-scented oxycarpus = with sour fruit phu = rotten saccharatus = sugary sweet salsillus = salty suaveolens = sweet smell fragrant horticulture plants: Daphne odora (spring air), Galium odoratum (woodruff), Lathyrus odoratus (sweet pea), Myrrhis odorata (sweet cicely), Nymphea odorata (sweet lotus), Reseda odorata (mignonette), Viola odorata (sweet violet) Plant names explained.

Polemonium viscosum has blue to purple flowers. Some of them have a sweet scent (esters or terpenes) others have a skunky smell (amines). The pollinator of the Polemonium is the bumblebee Bombus kirbyellus, which prefers sweet smelling flowers without consideration for color. Îa lot of questions like “ was there another pollinator before ? or “do the skunky flowers deter pollen robbers like ants?” If so it is an example for smell as defense What about Kerner’s rule: Scent of foliage is mostly insect repellent while Scent of flowers is mostly insect attractant William Agosta “ Thieves, deceivers and killers. Tales of chemistry in nature”, Princeton University Press 2001 5 groups of flower odors according to Kerner von Marilaun (1904) Kerner’s rule: Scent of foliage is mostly insect repellent while Scent of flowers is mostly insect attractant Alliums (e.g. garlic) honey-smelling flowers, negi smelling foliage Conium maculatum (hemlock) honey-smelling flower, repulsive smell of mice for the rest • Exceptions to the rule (same odor in flower and vegetation): Primula auricula, Viola odorata, Gaultheria procumbens (wintergreen), woodruff (Galium odoratum), Lavendula vera etc. 1.
