Marigolds were first discovered by the Portuguese in Central America in the 16th century. Marigolds are hardy, annual plants and are great plants for cheering up any garden. Broadly, there are two genuses which are referred to by the common name, Marigolds viz., Tagetes and Celandula. Tagetes includes African Marigolds and French Marigolds. Celandula includes Pot Marigolds. Kingdom : Plantae Division : Magnoliophyta Class : Magnoliopsida Order : Asterales Family : Asteraceae Genus : Tagetes, Calendula Marigolds come in different colors, yellow and orange being the most common. Most of the marigolds have strong, pungent odor and have has great value in cosmetic treatment. There are many varieties of Marigolds available today. Some of the major Marigold varieties are listed below: African or American Marigolds (Tagetes erecta): These marigolds are tall, erect-growing plants up to three feet in height. The flowers are globe-shaped and large. Flowers may measure up to 5 inches across. African Marigolds are very good bedding plants. These flowers are yellow to orange and do not include red colored Marigolds. The Africans take longer to reach flowering stage than the French type. French Marigolds (Tagetes patula): Marigold cultivars in this group grow 5 inches to 18 inches high. Flower colors are red, orange and yellow. Red and orange bicolor patterns are also found. Flowers are smaller, (2 inches across). French Marigolds are ideal for edging flowerbeds and in mass plantings. They also do well in containers and window boxes. Signet Marigolds (T. signata 'pumila'): The signet Marigolds produce compact plants with finely divided, lacy foliage and clusters of small, single flowers. They have yellow to orange colored, edible flowers.The flowers of signet marigolds have a spicy tarragon flavor. The foliage has a pleasant lemon fragrance. Signet Marigolds are excellent plants for edging beds and in window boxes. Mule Marigolds: These marigolds are the sterile hybrids of tall African and dwarf French marigolds, hence known as mule Marigolds. Most triploid cultivars grow from 12 to 18 inches high. Though they have the combined qualities of their parents, their rate of germination is low. Marigold (Calendula) is an extremely effective herb for the treatment of skin problems and can be used wherever there is inflammation of the skin, whether due to infection or physical damage; for example, crural ulceration, varicose veins, haemorrhoids, anal fissures, mastitis, sebaceous cysts, impetigo or other inflamed cutaneous lesions. As an ointment, Marigold (Calendula) is an excellent cosmetic remedy for repairing minor damage to the skin such as subdermal broken capillaries or sunburn. The sap from the stem is reputed to remove warts, corns and calluses.

Lovage-, Levisticum officinale, is a perennial herb that looks like parsley and is in the parsley, or Apiaceae, family, like anise, dill, caraway, cumin, and fennel. Lovage is native to mountainous areas of southern Europe and Asia Minor. It is sometimes called sea parsley. Lovage (Levisticum officinale) is a plant, the leaves and seeds or fruit of which are used to flavor food, especially in South European cuisine. It is a tall (3 to 9 ft) perennial that vaguely resembles its cousin celery in appearance and in flavor. Lovage also sometimes gets referred to as smallage, but this is more properly used for celery. Herb (Levisticum officinale) of the parsley family, native to southern Europe. It is cultivated for its stalks and foliage, which are used for tea, as a vegetable, and to flavour foods. Its rhizomes are used as a carminative, and the seeds are used for flavouring desserts. Oil obtained from the flowers is used in perfumery. The French call lovage céleri bâtard, "false celery," because of its strong resemblance to that plant. Lovage has been used since Greek and Roman times for everything from a seasoning, to a curative for maladies ranging from indigestion to freckles, to a love potion. It grows up to 7 feet high and has large, dark green, celerylike leaves. The flavor of the pale stalks is that of very strong celery. The leaves, seeds and stalks can be used (in small amounts because of their potent flavor) in salads, stews and other dishes such as fowl and game. The stalks can be cooked as a vegetable. Dried lovage leaves and chopped or powdered stalks can be found in natural food stores and gourmet markets. The seeds are commonly called celery seed. Lovage is also called smallage and smellage. lovage, tall perennial herb (Levisticum officinale) of the family Umbelliferae (parsley family), native to the mountains of S Europe and cultivated elsewhere. Its aromatic fruits are used in soups and as a flavoring for confectionery and for some liqueurs. An aromatic oil extracted from the roots has been used medicinally and also for flavoring. The edible leaves are usually used like celery. Lovage is classified in the division Magnoliophyta, class Magnoliopsida, order Apiales, family Umbelliferae.

Capsicum Oleoresin is prepared by extracting the crushed capsicum (Capsicum Annum Linn) with volatile solvents by percolation method. It contains the pungent principles, capsicin not less that 8 percent. It also contains the red colouring matter called Capsanthin. This product is a powerful irritant and a carminative, which is also used as a counter irritant in lumbago and neuralgia. It can also be used to treat stomach ache that involves poorly functioning stomach muscles and as an antibacterial agents. Extraction of oleoresin capsicum from peppers involves finely ground capsicum, from which capsaicin is extracted in an organic solvent such as ethanol. The solvent is then evaporated, and the remaining wax like resin is the oleoresin capsicum. An emulsifier such as propylene glycol is used to suspend the OC in water, and pressurized to make it aerosol in pepper spray. The high performance liquid chromatography (HPLC) method is used to measure the amount of capsaicin within pepper sprays. Scoville Heat Units (SHU) are used to measure the concentration or "heat" of pepper spray. A synthetic analogue of capsaicin, pelargonic acid vanillylamide (desmethyldihydrocapsaicin), is used in another version of pepper spray known as PAVA spray which is used in the United Kingdom. Another synthetic counterpart of pepper spray, pelargonic acid morpholide, was developed and is widely used in Russia. Its effectiveness compared to natural pepper spray is unclear. Pepper spray typically comes in canisters, which are often small enough to be carried or concealed in a pocket or purse. Pepper spray can also be bought concealed in items such as rings. There are also pepper spray projectiles available, which can be fired from a paintball gun. It has been used for years against demonstrators. Derived from chilli peppers, oleoresin capsicum is the active ingredient in pepper spray and in some topical pain relievers.

Paprika is a spice made from the grinding of dried fruits of Capsicum annuum (e.g., bell peppers or chili peppers). In many European languages, the word paprika refers to bell peppers themselves. The seasoning is used in many cuisines to add color and flavor to dishes. Paprika can range from sweet (mild, not hot) to spicy (hot). Flavors also vary from country to country. Usage Paprika is used as an ingredient in a broad variety of dishes throughout the world. Paprika is principally used to season and color rices, stews, and soups, such as goulash, and in the preparation of sausages as an ingredient that is mixed with meats and other spices. Paprika can also be used with henna to bring a reddish tint to hair when coloring it. Paprika powder can be added to henna powder when prepared at home. Paprika is also high in other antioxidants, containing about 10% of the level found in berries. Prevalence of nutrients, however, must be balanced against quantities ingested, which are generally negligible for spices. Paprika oleoresin (also known as paprika extract) is an oil soluble extract from the fruits of Capsicum Annum Linn or Capsicum Frutescens(Indian red chillies), and is primarily used as a colouring and/or flavouring in food products. ... Oleoresin Paprika is produced by the extraction of lipids and pigments from the pods of sweet red pepper, Capsicum Annuum L. Grown in temperate climates. An oil soluble extract with it is widely used in processed foods such as sausage, dressings, dry soluble seasonings, food coatings, and snack food seasonings. Paprika Oleoresin, obtained from Capsicum, is a natural dye used as a colorant and a flavor enhancer in foods, meats and pharmaceuticals. It is obtained by percolation with a volatile solvent which should be removed subsequently, such as acetone, trichloroethylene, 2-propanol, methanol, ethanol and hexane. Capsaicin is the major flavouring compound, whereas capsanthin and capsorubin are major colouring compounds among variety of coloured compounds present in Paprika Oleoresin. Uses Foods coloured with paprika oleoresin include cheese, orange juice, spice mixtures, sauces, sweets and emulsified processed meats. In poultry feed it is used to deepen the colour of egg yolks.

Mace Botanical: Myristica fragrans Family: N.O. Myristicaceae Hindi Name: Mace - Javitri General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia. Geographical Sources The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed. Varieties -> Whole nutmegs are grouped under three broad quality classifications: 1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes. 2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%. 3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%. Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter. Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
