FAMILY: Orchidaceae
SYNONYMS: V. fragrans, common vanilla, Mexican vanilla, Bourbon vanilla, Reunion vanilla.
GENERAL DESCRIPTION: A perennial herbaceous climbing vine up to 25 metres high, with green stems and large white flowers which have a deep narrow trumpet. The green capsules or fruits are ready to pick after eight or nine months on the plant, and then have to be ‘cured’. The immature vanilla ‘pod’ or ‘bean’ which is from 14 cms to 22 cms long, has to be fermented and dried to turn it into the fragrant brown vanilla pods of commerce – a process which can take up to six months to complete. During the drying process vanillin can accumulate as white crystals on the surface of the bean.
DISTRIBUTION: Native to Central America and Mexico; cultivated mainly in Madagascar and Mexico; also Tahiti, the Comoro Islands, East Africa and Indonesia, although the pods are often processed in Europe or the USA.
OTHER SPECIES: There are several different species of vanilla, such as the Tahiti vanilla (V. tahitensis) which is a smaller bean, and the ‘vanillons’ type (V. pompona) which produces an inferior quality oil.
HERBAL/FOLK TRADITION: When vanilla is grown in cultivation the deep trumpet-shaped flowers have to be hand-pollinated; except in Mexico where the native humming birds do most of the work!
ACTIONS: Balsamic.
EXTRACTION: A resinoid (often called an oleoresin) by solvent extraction from the ‘cured’ vanilla beans. (An absolute is occasionally produced by further extraction from the resinoid.)
CHARACTERISTICS: A viscous dark brown liquid with a rich, sweet, balsamic, vanilla-like odour. It blends well with sandalwood, vetiver, opopanax, benzoin, balsams and spice oils.
PRINCIPAL CONSTITUENTS: Vanillin (1.3–2.9 per cent) with over 150 other constituents, many of them traces: hydroxybenzaldehyde, acetic acid, isobutyric acid, caproic acid, eugenol and furfural, among others.
SAFETY DATA: Non-toxic, common sensitizing agent. Widely adulterated.
AROMATHERAPY/HOME: USE None.
OTHER USES: Used in pharmaceutical products as a flavouring agent. Used as a fragrance ingredient in perfumes, especially oriental types. Widely used to flavour tobacco and as a food flavouring, mainly in ice cream, yoghurt and chocolate.
Nutritional Profile Energy value (calories per serving): Moderate Protein: Low (cocoa powder) High (chocolate) Fat: Moderate Saturated fat: High Cholesterol: None Carbohydrates: Low (chocolate) High (cocoa powder) Fiber: Moderate (chocolate) High (cocoa powder) Sodium: Moderate Major vitamin contribution: B vitamins Major mineral contribution: Calcium, iron, copper
About the Nutrients in This Food Cocoa beans are high-carbohydrate, high-protein food, with less dietary fiber and more fat than all other beans, excepting soy beans. The cocoa bean’s dietary fiber includes pectins and gums. Its proteins are limited in the essential amino acids lysine and isoleucine. Cocoa butter, the fat in cocoa beans, is the second most highly saturated vegetable fat (coconut oil is number one), but it has two redeeming nutritional qualities. First, it rarely turns rancid. Second, it melts at 95°F, the temperature of the human tongue. Cocoa butter has no cholesterol; neither does plain cocoa powder or plain dark chocolate. Cocoa beans have B vitamins (thiamine, riboflavin, niacin) plus min- erals (iron, magnesium, potassium, phosphorus, and copper). All chocolate candy is made from chocolate liquor, a thick paste pro- duce by roasting and grinding cocoa beans. Dark (sweet) chocolate is made of chocolate liquor, cocoa butter, and sugar. Milk chocolate is made of choc- olate liquor, cocoa butter, sugar, milk or milk powder, and vanilla. White * These values apply to plain cocoa powder and plain unsweetened chocolate. Add- ing other foods, such as milk or sugar, changes these values. For example, there is no cholesterol in plain bitter chocolate, but there is cholesterol in milk chocolate. chocolate is made of cocoa butter, sugar, and milk powder. Baking chocolate is unsweetened dark chocolate. The most prominent nutrient in chocolate is its fat. Fat Content in One Ounce of Chocolate

The Most Nutritious Way to Serve This Food With low-fat milk to complete the proteins without adding saturated fat and cholesterol. NOTE : Both cocoa and chocolate contain oxalic acid, which binds with calcium to form cal- cium oxalate, an insoluble compound, but milk has so much calcium that the small amount bound to cocoa and chocolate hardly matters. Chocolate skim milk is a source of calcium.
Diets That May Restrict or Exclude This Food Antiflatulence diet Low-calcium and low-oxalate diet (to prevent the formation of calcium oxalate kidney stones) Low-calorie diet Low-carbohydrate diet Low-fat diet Low-fat, controlled-cholesterol diet (milk chocolates) Low-fiber diet Potassium-regulated (low-potassium) diet
Buying This Food Look for: Tightly sealed boxes or bars. When you open a box of chocolates or unwrap a candy bar, the chocolate should be glossy and shiny. Chocolate that looks dull may be stale, or it may be inexpensively made candy without enough cocoa butter to make it gleam and give it the rich creamy mouthfeel we associate with the best chocolate. (Fine chocolate melts evenly on the tongue.) Chocolate should also smell fresh, not dry and powdery, and when you break a bar or piece of chocolate it should break cleanly, not crumble. One exception: If you have stored a bar of chocolate in the refrigerator, it may splinter if you break it without bringing it to room temperature first.
Storing This Food Store chocolate at a constant temperature, preferably below 78°F. At higher temperatures, the fat in the chocolate will rise to the surface and, when the chocolate is cooled, the fat will solidif y into a whitish powdery bloom. Bloom is unsightly but doesn’t change the chocolate’s taste or nutritional value. To get rid of bloom, melt the chocolate. The chocolate will turn dark, rich brown again when its fat recombines with the other ingredients. Chocolate with bloom makes a perfectly satisfactory chocolate sauce. Dark chocolate (bitter chocolate, semisweet chocolate) ages for at least six months after it is made, as its flavor becomes deeper and more intense. Wrapped tightly and stored in a cool, dry cabinet, it can stay fresh for a year or more. Milk chocolate ages only for about a month after it is made and holds its peak flavor for about three to six months, depending on how carefully it is stored. Plain cocoa, with no added milk powder or sugar, will stay fresh for up to a year if you keep it tightly sealed and cool.
What Happens When You Cook This Food Chocolate burns easily. To melt it without mishap, stir the chocolate in a bowl over a pot of hot water or in the top of a double boiler or put the chocolate in a covered dish and melt it in the microwave (which does not get as hot as a pot on the store). Simple chemistry dictates that chocolate cakes be leavened with baking soda rather than baking powder. Chocolate is so acidic that it will upset the delicate balance of acid (cream of tartar) and base (alkali = sodium bicarbonate = baking soda) in baking powder. But it is not acidic enough to balance plain sodium bicarbonate. That’s why we add an acidic sour-milk product such as buttermilk or sour cream or yogurt to a chocolate cake. Without the sour milk, the batter would be so basic that the chocolate would look red, not brown, and taste very bitter.
How Other Kinds of Processing Affect This Food Freezing. Chocolate freezes and thaws well. Pack it in a moistureproof container and defrost it in the same package to let it reabsorb moisture it gave off while frozen.
Medical Uses and/or Benefits Mood elevator. Chocolate’s reputation for making people feel good is based not only on its caffeine content—19 mg caffeine per ounce of dark (sweet) chocolate, which is one-third the amount of caffeine in a five-ounce cup of brewed coffee—but also on its naturally occurring mood altering chemicals phenylethylalanine and anandamide. Phenylethylalanine is found in the blood of people in love. Anandamide stimulates areas of your brain also affected by the active ingredients in marijuana. (NOTE : As noted by the researchers at the Neurosci- ences Institute in San Diego who identified anandamide in chocolate in 1996, to get even the faintest hint of marijuana-like effects from chocolate you would have to eat more than 25 pounds of the candy all at once.) Possible heart health benefits. Chocolate is rich in catechins, the antioxidant chemicals that give tea its reputation as a heart-protective anticancer beverage (see tea). In addition, a series of studies beginning with those at the USDA Agricultural Research Center in Peoria, Illinois, suggest that consuming foods rich in stearic acid like chocolate may reduce rather than raise the risk of a blood clot leading to a heart attack. Possible slowing of the aging process. Chocolate is a relatively good source of copper, a mineral that may play a role in slowing the aging process by decreasing the incidence of “protein glycation,” a reaction in which sugar molecules ( gly = sugar) hook up with protein molecules in the bloodstream, twisting the protein molecules out of shape and rendering them unusable. This can lead to bone loss, rising cholesterol, cardiac abnormalities, and a slew of other unpleasantries. In people with diabetes, excess protein glycation may be one factor involved in complications such as loss of vision. Ordinarily, increased protein glyca- tion is age-related. But at the USDA Grand Forks Human Nutrition Research Center in North Dakota, agricultural research scientist Jack T. Saari has found that rats on copper-deficient diets experience more protein glycation at any age than other rats. A recent USDA survey of American eating patterns says that most of us get about 1.2 mg copper a day, considerably less than the Estimated Safe and Adequate Daily Dietary Intake (ESADDI) or 1.5 mg to 3 mg a day. Vegetarians are less likely to be copper deficient because, as Saari notes, the foods highest in copper are whole grains, nuts, seeds, and beans, including the cocoa bean. One ounce of dark chocolate has .25 mg copper (8 –17 percent of the ESADDI).
Adverse Effects Associated with This Food Possible loss of bone density. In 2008, a team of Australian researchers at Royal Perth Hos- pital, and Sir Charles Gairdner Hospital published a report in the American Journal of Clinical Nutrition suggesting that women who consume chocolate daily had 3.1 percent lower bone density than women who consume chocolate no more than once a week. No explanation for the reaction was proposed; the finding remains to be confirmed. Possible increase in the risk of heart disease. Cocoa beans, cocoa powder, and plain dark chocolate are high in saturated fats. Milk chocolate is high in saturated fats and cholesterol. Eating foods high in saturated fats and cholesterol increases the amount of cholesterol in your blood and raises your risk of heart disease. NOTE : Plain cocoa powder and plain dark chocolate may be exceptions to this rule. In studies at the USDA Agricultural Research Center in Peoria, Illinois, volunteers who consumed foods high in stearic acid, the saturated fat in cocoa beans, cocoa powder, and chocolate, had a lower risk of blood clots. In addition, chocolate is high in flavonoids, the antioxidant chemicals that give red wine its heart-healthy reputation. Mild jitters. There is less caffeine in chocolate than in an equal size serving of coffee: A five- ounce cup of drip-brewed coffee has 110 to 150 mg caffeine; a five-ounce cup of cocoa made with a tablespoon of plain cocoa powder ( 1/3 oz.) has about 18 mg caffeine. Nonetheless, people who are very sensitive to caffeine may find even these small amounts problematic. Allergic reaction. According to the Merck Manual, chocolate is one of the 12 foods most likely to trigger the classic food allergy symptoms: hives, swelling of the lips and eyes, and upset stomach.* The others are berries (blackberries, blueberries, raspberries, strawberries), corn, eggs, fish, legumes (green peas, lima beans, peanuts, soybeans), milk, nuts, peaches, pork, shellfish, and wheat (see wheat cer ea ls).
Food/Drug Interactions Monoamine oxidase (MAO) inhibitors. Monoamine oxidase inhibitors are drugs used to treat depression. They inactivate naturally occurring enzymes in your body that metabolize tyra- mine, a substance found in many fermented or aged foods. Tyramine constricts blood vessels and increases blood pressure. Caffeine is a substance similar to tyramine. If you consume excessive amounts of a caffeinated food, such as cocoa or chocolate, while you are taking an M AO inhibitor, the result may be a hypertensive crisis. False-positive test for pheochromocytoma. Pheochromocytoma, a tumor of the adrenal gland, secretes adrenalin, which the body converts to VM A (vanillylmandelic acid). VM A is excreted in urine, and, until recently, the test for this tumor measured the level of VM A in the urine. In the past, chocolate and cocoa, both of which contain VM A, were eliminated from the patient’s diet prior to the test lest they elevate the level of VM A in the urine and produce a false-positive result. Today, more finely drawn tests usually make this unnecessary. * The evidence link ing chocolate to allergic or migraine headaches is inconsistent. In some people, phenylet hylamine (PEA) seems to cause headaches similar to t hose induced by t yramine, anot her pressor amine. The PEA-induced headache is unusual in t hat it is a delayed react ion t hat usually occurs 12 or more hours after t he chocolate is eaten.... chocolate

SYNONYMS: Copahu balsam, copaiba, copaiva, Jesuit’s balsam, Maracaibo balsam, para balsam.
GENERAL DESCRIPTION: Wild-growing tropical tree up to 18 metres high, with thick foliage and many branches. The natural oleoresin occurs as a physiological product from various Copaifera species. Not a ‘true’ balsam.
DISTRIBUTION: Native to north east and central South America. Mainly produced in Brazil; also Venezuela, Guyana, Surinam and Colombia.
OTHER SPECIES: Several Copaifera speices yield an oleoresin: the Venezuelan type ‘Maracaibo balsam’ has a low oil content, the Brazilian type ‘para balsam’ has a high oil content. See also Botanical Classification section.
HERBAL/FOLK TRADITION: Used for centuries in Europe in the treatment of chronic cystitis and bronchitis; also for treating piles, chronic diarrhoea and intestinal problems.
ACTIONS: Batericidal, balsamic, disinfectant, diuretic, expectorant, stimulant.
EXTRACTION: 1. The crude balsam is collected by drilling holes into the tree trunks; it is one of the most plentiful naturally occurring perfume materials. 2. An essential oil is obtained by dry distillation from the crude balsam. It is mainly the ‘para balsams’ with a high oil content (60–80 per cent), which are used for distillation.
CHARACTERISTICS: 1. The crude balsam is a viscous, yellowy-brown or greenish-grey liquid which hardens upon exposure to air with a mild, woody, slightly spicy odour. It blends well with styrax, amyris, lavandin, cedarwood, lavender, oakmoss, woods and spices. 2. The oil is a pale yellow or greenish mobile liquid with a mild, sweet, balsamic-peppery odour. It blends well with cananga, ylang ylang, vanilla, jasmine, violet and other florals.

BALSAM, PERU... balsam, copaiba
FAMILY: Styracaceae
SYNONYMS: Gum benzoin, gum benjamin, styrax benzoin.
GENERAL DESCRIPTION: A large tropical tree up to 20 metres high with pale green citrus-like leaves, whitish underneath, bearing hard-shelled flattish fruit about the size of a nutmeg. The benzoin is a pathological product, formed when the trunk is cut; the tree exudes a balsamic resin which hardens upon exposure, to air and sunlight.
DISTRIBUTION: Native to tropical Asia; the two main regions of production are Sumatra, Java and Malaysia for ‘Sumatra’ benzoin, and Laos, Vietnam, Cambodia, China and Thailand for ‘Siam’ benzoin.
OTHER SPECIES: There are many different varieties within the Styrax family which produce benzoin, but these are generally classified under either Sumatra benzoin (S. paralleloneurus) or Siam benzoin (S. tonkinensis) – see also Botanical Classification section.
HERBAL/FOLK TRADITION: It has been used for thousands of years in the east as a medicine and incense; the fumigations were believed to drive away evil spirits. It was used by the Chinese herbalists for its heating and drying qualities, as a good urinary antiseptic and as an aid to digestion.
In the west, it is best known in the form of compound tincture of benzoin or Friars Balsam, used for respiratory complaints. Externally it is used for cuts and irritable skin conditions; internally it is used as a carminative for indigestion, etc. It also acts as a preservative of fats.
ACTIONS: Anti-inflammatory, anti-oxidant, antiseptic, astringent, carminative, cordial, deodorant, diuretic, expectorant, sedative, styptic, vulnerary.
EXTRACTION: The crude benzoin is collected from the trees directly. Benzoin resinoid, or ‘resin absolute’, is prepared from the crude using solvents, for example benzene and alcohol, which are then removed. Commercial benzoin is usually sold dissolved in ethyl glycol or a similar solvent. A ‘true’ absolute is also produced in small quantities.
CHARACTERISTICS: 1. Sumatra crude benzoin occurs as greyish-brown brittle lumps with reddish streaks, with a styrax-like odour. There are several different qualities available; the so-called ‘almond’ grade is considered superior. 2. Siam benzoin comes in pebble or tear-shaped orange-brown pieces, with a sweet-balsamic vanilla-like scent, this type having a more refined odour than the Sumatra type.
Benzoin resinoid is produced from both the Siam and Sumatra types, or a mix of the two. It is an orange-brown viscous mass with an intensely rich sweet-balsamic odour. It blends well with sandalwood, rose, jasmine, copaiba balsam, frankincense, myrrh, cypress, juniper, lemon, coriander and other spice oils.
PRINCIPAL CONSTITUENTS: 1. Sumatra Benzoin: mainly coniferyl cinnamate and sumaresinolic acid, with benzoic acid, cinnamic acid, and traces of styrene, vanillin and benzaldehyde. 2. Siam benzoin: mainly coniferyl benzoate (65–75 per cent), with benzoic acid, vanillin, siaresinolic acid and cinnamyl benzoate.
SAFETY DATA: Non-toxic, non-irritant, possible sensitization. Compound benzoin tincture is ‘regarded as moderately toxic, due probably to occasional contact dermatitis developed in some individuals … which contains, in addition to benzoin, aloe, storax, Tolu balsam and others.’.
AROMATHERAPY/HOME: USE
Skin Care: Cuts, chapped skin, inflamed and irritated conditions.
Circulation, Muscles And Joints: Arthritis, gout, poor circulation, rheumatism.
Respiratory System: Asthma, bronchitis, chills, colic, coughs, laryngitis.
Immune System: ’Flu.
Nervous System: Nervous tension and stress-related complaints. It warms and tones the heart and circulation, both physically and metaphorically: ‘This essence creates a kind of euphoria; it interposes a padded zone between us and events.’.
OTHER USES: Compound benzoin tincture is used in pharmaceuticals and in dentistry to treat gum inflammation. The resinoid and absolute are used extensively as fixatives and fragrance components in soaps, cosmetics, toiletries and perfumes, especially Siam benzoin. Both types are used in most food categories, including alcoholic and soft drinks.... benzoin

GENERAL DESCRIPTION: A herbaceous perennial plant distinguished by a naked receptacle and feathery pappus, with large, fleshy, dark green leaves, clasped at the base. When fresh, the leaves have little odour but when dried they acquire a vanilla-like odour, largely due to the coumarin that can be seen in crystals on the upper sides of the leaves.
DISTRIBUTION: Native to eastern USA; gathered on the savannah land between North Carolina and Florida.
OTHER SPECIES: There are several species of deertongue native to America, for example blazing star or prairie pine (Liatris squarrosa), and gayfeather (L. spicata). Not to be confused with the common vanilla (Vanilla planifolia) or with the European hound’s tongue (Cynoglossum officinale), all of which have been used in herbal medicine.
HERBAL/FOLK TRADITION: The roots have been used for their diuretic effects, and applied locally for sore throats and gonorrhoea. It has also been used as a tonic in treating malaria. In folklore the plant is associated with contraception and sterility in women.
ACTIONS: Antiseptic, demulcent, diaphoretic, diuretic, febrifuge, stimulant, tonic.
EXTRACTION: Oleoresin by solvent extraction from the dried leaves.
CHARACTERISTICS: A dark green, heavy, viscous liquid with a rich, herbaceous, new-mown hay scent. It blends well with oakmoss, labdanum, lavandin, frankincense, clove, patchouli and oriental-type fragrances.
PRINCIPAL CONSTITUENTS: Mainly coumarin (1.6 per cent), with dihydrotoumarin and terpenes, aldehydes and ketones.
SAFETY DATA: ‘Coumarin has toxic properties including liver injury and haemorrhages.’. (There is also the possibility of dermal irritation and phototoxicity due to the lactones present.)

FAMILY: Asteraceae (Compositae)
SYNONYMS: Estragon (oil), little dragon, Russian tarragon.
GENERAL DESCRIPTION: A perennial herb with smooth narrow leaves; an erect stem up to 1.2 metres tall, and small yellowy-green, inconspicuous flowers.
DISTRIBUTION: Native to Europe, southern Russia and western Asia. Now cultivated worldwide, especially in Europe and the USA. The oil is mainly produced in France, Holland, Hungary and the USA.
OTHER SPECIES: The so-called French tarragon or ‘sativa’, which is cultivated as a garden herb, is a smaller plant with a sharper flavour than the Russian type and is a sterile derivative of the wild species.
HERBAL/FOLK TRADITION: The leaf is commonly used as domestic herb, especially with chicken or fish, and to make tarragon vinegar. The name is thought to derive from an ancient use as an antidote to the bites of venomous creatures and ‘madde dogges’. It was favoured by the maharajahs of India who took it as a tisane, and in Persia it was used to induce appetite.
‘The leaves, which are chiefly used, are heating and drying, and good for those that have the flux, or any prenatural discharge.’. The leaf was also formerly used for digestive and menstrual irregularities, while the root was employed as a remedy for toothache.
ACTIONS: Anthelmintic, antiseptic, antispasmodic, aperitif, carminative, digestive, diuretic, emmenagogue, hypnotic, stimulant, stomachic, vermifuge.
EXTRACTION: Essential oil by steam distillation from the leaves.
CHARACTERISTICS: A colourless or pale yellow mobile liquid (turning yellow with age), with a sweet-anisic, spicy-green scent. It blends well with labdanum, galbanum, lavender, oakmoss, vanilla, pine and basil.
PRINCIPAL CONSTITUENTS: Estragole (up to 70 per cent), capillene, ocimene, nerol, phellandrene, thujone and cineol, among others.
SAFETY DATA: Moderately toxic due to ‘estragole’ (methyl chavicol); use in moderation only. Possibly carcinogenic. Otherwise non-irritant, non-sensitizing. Avoid during pregnancy.
AROMATHERAPY/HOME: USE
Digestive system: Anorexia, dyspepsia, flatulence, hiccoughs, intestinal spasm, nervous indigestion, sluggish digestion.
Genito-urinary system: Amenorrhoea, dysmenorrhoea, PMT.
OTHER USES: Used as a fragrance component in soaps, detergents, cosmetics and perfumes. Employed as a flavour ingredient in most major food categories, especially condiments and relishes, as well as alcoholic and soft drinks.... tarragon
FAMILY: Ericaceae
SYNONYMS: Aromatic wintergreen, checkerberry, teaberry, gaultheria (oil).
GENERAL DESCRIPTION: A small evergreen herb up to 15 cm high with slender creeping stems shooting forth erect twigs with leathery serrated leaves and drooping white flowers, which are followed by fleshy scarlet berries.
DISTRIBUTION: Native to North America, especially the north eastern region and Canada. The oil is produced in the USA.
OTHER SPECIES: There are several other Gaultheria species which are also used for oil production, sharing similar properties.
HERBAL/FOLK TRADITION: The plant has been used for respiratory conditions such as chronic mucous discharge, but is mainly employed for joint and muscular problems such as lumbago, sciatica, neuralgia, myalgia, etc. The dried leaf and stem are current in the British Herbal Pharmacopoeia as a specific for rheumatoid arthritis.
The essential oil has been used interchangeably with sweet birch oil, both being made up almost exclusively of methyl salicylate.
ACTIONS: Analgesic (mild), anti-inflammatory, antirheumatic, antitussive, astringent, carminative, diuretic, emmenagogue, galactagogue, stimulant.
EXTRACTION: Essential oil by steam (or water) distillation from the leaf, previously macerated in warm water. The essential oil does not occur crudely in the plant, but is only produced during the process of decomposition in warm water.
CHARACTERISTICS: A pale yellow or pinkish liquid with an intense sweet-woody, almost fruity odour. It blends well with oregano, mints, thyme, ylang ylang, narcissus and vanilla.
PRINCIPAL CONSTITUENTS: Almost exclusively methyl salicylate (up to 98 per cent), with formaldehyde and gaultheriline.
SAFETY DATA: Toxic, irritant and sensitizing – an environmental hazard or marine pollutant. The true oil is almost obsolete, having been replaced by synthetic methyl salicylate. See also sweet birch oil.
AROMATHERAPY/HOME: USE None. ‘Avoid both internally and externally.’.
OTHER USES: Some pharmaceutical use, such as ‘Olbas’ oil. Some perfumery applications especially in forest-type fragrances. Extensively used as a flavouring agent in the USA for toothpaste, chewing gum, root beer, Coca-Cola, and other soft drinks.... wintergreen
