Cashew
The Cashew (Anacardium occidentale; syn.Anacardium curatellifoliumA.St.-Hil.) is a tree in the flowering plant family Anacardiaceae. The plant is native to northeastern Brazil, where it is called by its Portuguese name Caju (the fruit) or Cajueiro (the tree). It is now widely grown in tropicalclimates for its cashew "nuts" (see below) and cashew apples.
'Anacardium occidentale', from Koehler's 'Medicinal-Plants' (1887)
Tree shape
It is a small evergreen tree growing to 10-12 m tall, with a short, often irregularly-shaped trunk. The leaves are spirally arranged, leathery textured, elliptic to obovate, 4-22 cm long and 2-15 cm broad, with a smooth margin. The flowers are produced in a panicle or corymb up to 26 cm long, each flower small, pale green at first then turning reddish, with five slender, acute petals 7-15 mm long.
What appears to be the fruit of the cashew tree is an oval or pear-shaped accessory fruit or false fruit that develops from the receptacle of the cashew flower. Called the cashew apple, better known in Central America as "mara��n", it ripens into a yellow and/or red structure about 5�11 cm long.
The true fruit of the cashew tree is a kidney or boxing-glove shaped drupe that grows at the end of the pseudofruit. Actually, the drupe develops first on the tree, and then the peduncle expands into the pseudofruit. Within the true fruit is a single seed, the cashew nut. Although a nut in the culinary sense, in the botanical sense the fruit of the cashew is a seed. However, the true fruit is classified as a nut by some botanists. The seed is surrounded by a double shell containing a caustic phenolic resin, urushiol, a potent skin irritant toxin (also found in the related poison-ivy). Some people are allergic to cashews, but cashews are a less frequent allergen than some other nuts.
Ginger
Ginger is commonly used as a spice in cuisines throughout the world. Though commonly referred to as a root, it is actually the rhizome of the monocotyledonous perennial plant Zingiber officinale.

Ginger section
Ginger contains up to 3% of an essential oil that causes the fragrance of the spice. The main constituents are sesquiterpenoids with (-)-zingiberene as the main component. Lesser amounts of other sesquiterpenoids (β-sesquiphellandrene, bisabolene and farnesene) and a small monoterpenoid fraction (β-phelladrene, cineol, and citral) have also been identified.
The pungent taste of ginger is due to nonvolatile phenylpropanoids (particularly gingerol and zingerone) and diarylheptanoids (gingeroles and shoagoles); the latter are more pungent and form from the former when ginger is dried. Cooking ginger transforms gingerol into zingerone, which is less pungent and has a spicy-sweet aroma.[2]
25.4-pound ginger root
Young ginger roots are juicy and fleshy with a very mild taste. They are often pickled in vinegar or sherry as a snack or just cooked as an ingredient in many dishes. They can also be stewed in boiling water to make ginger tea, to which honey is often added as a sweetener. Mature ginger roots are fibrous and nearly dry. The juice from old ginger roots is extremely potent and is often used as a spice in Chinese cuisine to flavor dishes such as in seafood and mutton.
Ginger is also candied, is used as a flavoring for candy, cookies, crackers and cake, and is the main flavor in ginger ale, a sweet, carbonated, non-alcoholicbeverage, as well as the similar, but somewhat spicier beverage ginger beer. A ginger-flavored liqueur called Canton is produced in the Guangdong province of China; it is advertised to be based on a recipe created for the rulers of the Qing Dynasty and made from six different varieties of ginger. Green ginger wine is a ginger flavoured wine produced in the United Kingdom by Crabbie's and Stone's and traditionally sold in a green glass bottle. Ginger is also used as a spice added to hot coffee and tea.
In Japan, ginger is pickled to make beni shoga and gari or grated and used raw on tofu or noodles.
In Western cuisine, ginger is traditionally restricted to sweet foods, such as ginger ale, gingerbread, ginger snaps, ginger cake and ginger biscuits.
Powdered dry ginger root (ground ginger) is typically used to add spiciness to gingerbread and other recipes. Ground and fresh ginger taste quite different and ground ginger is a particularly poor substitute for fresh ginger. Fresh ginger can be successfully substituted for ground ginger and should be done at a ratio of 6 parts fresh for 1 part ground. You generally achieve better results by substituting only half the ground ginger for fresh ginger.
In Myanmar, ginger is used in a salad dish called gyin-tho, which consists of shredded ginger preserved in oil, and a variety of nuts and seeds.
In traditional Korean Kimchi, ginger is minced finely and added into the ingredients of the spicy paste just before the fermenting process.
In India, ginger is used in all sub-varieties of the Indian cuisines. In south India, ginger is used in the production of a candy called Inji-murappa ("ginger candy" from Tamil). This candy is mostly sold by vendors to bus passengers in bus stops and in small tea shops as a locally produced item. Candied ginger is also very famous around these parts. Additionally, in Tamil Nadu, especially in the Tanjore belt, a variety of ginger which is less spicy is used when tender to make fresh pickle with the combination of lemon juice, salt and tender green chillies. This kind of pickle was generally made before the invention of refrigeration and stored for a maximum of 4-5 days. The pickle gains a mature flavor when the juices cook the ginger over the first 24 hours.
In South East Asia, the flower of a type of ginger is used in cooking. This unopened flower is known in the Malay language as Bunga Kantan, and is used in salads and also as garnish for sour-savoury soups, like Assam Laksa.
Ginger has a sialagogue action, stimulating the production of saliva.
One medical research study had results indicating that ginger might be an effective treatment for nausea caused by motion sickness or other illness,[3] The study however, failed to show a significant difference between ginger and a placebo. There are several proposed mechanisms of action for the anti-emetic properties of ginger but there is not yet conclusive support for any particular model.
Modern research on nausea and motion sickness used approximately 1 gram of ginger powder daily. Though there are claims for efficacy in all causes of nausea, the PDR recommends against taking ginger root for morning sickness commonly associated with pregnancy due to possible mutagenic effects. Nevertheless, Chinese women traditionally have taken ginger root during pregnancy to combat morning sickness. The Natural Medicines Comprehensive Database (compiled by health professionals and pharmacists), states that ginger is likely safe for use in pregnancy when used orally in amounts found in foods. Ginger ale and ginger beer have been recommended as "stomach settlers" for generations in countries where the beverages are made. Ginger water was commonly used to avoid heat cramps in the United States in the past.
In Western-hemisphere nations, powdered dried ginger root is made into capsules and sold in pharmacies for medicinal use. In the US, ginger is not approved by the FDA for the treatment or cure of any disease. Ginger is instead sold as an unregulated dietary supplement. In India, ginger is applied as a paste to the temples to relieve headache. In Myanmar, ginger and local sweet (Htan nyat) which is made from palm tree juice are boiled together and taken to prevent the Flu. A hot ginger drink (made with sliced ginger cooked in sweetened water or a Coca-Cola-like drink) has been reported as a folk medicine for common cold.[4]
Ginger has also historically been used in folk medicine to treat inflammation, although medical studies as to the efficacy of ginger in decreasing inflammation have shown mixed results. There are several studies that demonstrate a decrease in joint pain from arthritis after taking ginger, though the results have not been consistent from study to study. It may also have blood thinning and cholesterol lowering properties, making it theoretically effective in treating heart disease; while early studies have shown some efficacy, it is too early to determine whether further research will bear this out.[1]
The medical form of ginger historically was called "Jamaica ginger"; it was classified as a stimulant and carminative, being much used for dyspepsia and colic. It was also frequently employed to disguise the taste of nauseous medicines. The tea brewed from this root was an old-fashioned remedy for colds.
The characteristic odor and flavor of ginger root is caused by a mixture of zingerone, shoagoles and gingerols, volatile oils that compose about 1%�3% by weight of fresh ginger. The gingerols have analgesic, sedative, antipyretic, antibacterial, and GI tract motility effects.
Ginger is on the GRAS list from FDA. However, like other herbs, ginger may be harmful because it may interact with other medications, such as warfarin; hence, a physician or pharmacist should be consulted before taking the herb. Ginger is also contraindicated in people suffering from gallstones, because the herb promotes the release of bile from the gallbladder. [2].
Some people are allergic to ginger. Generally, this is reported as having a gaseous component. This may take the form of flatulence, or it may take the form of an extreme constriction or tightening in the throat necessitating uncontrollable burping to relieve the pressure.
