Botanical latin name: Allium sativum (clove garlic: Ger.: knoblauch: Fr.: ail commun)
Garlic is a bulbous perennial growing to a height of 1 – 3 feet. It has pale pink or green-white flowers. It is a bulb made up of several cloves enclosed within the pink or white skin of the parent bulb. Garlic is used across the globe for flavoring various dishes and as a medicinal herb. It has a strong flavor due to the sulphur-containing allicin.
Garlic originates from Central Asia, but has spread to almost everywhere long time ago. Garlic is a cousin to onions, leeks, chives, and shallots. There are over 300 varieties of garlic grown worldwide. American garlic with white, papery skin and strong flavor is one of the most common. Italian and Mexican garlic with purple-colored skins have slightly milder flavor. The flavours of garlic and onion are produced by a family of flavour precursors (alkyl cysteine sulphoxides) synthesized within the cells of garlic and onion. An enzyme (alliinase) cleaves them to form compounds with volatile flavours. The characteristic mixtures of these flavour precursors produce smells unique to the members of the onion family Aliaceae. Many of the chemistry of the flavors in Aliaceae family still requires further study.
Garlic is very easy to grow: traditionally garlic was planted simply by burying individual cloves two to three inches deep in the fall. The individual garlic cloves multiply to form whole cloves by next summer.
Garlic is believed to have been originated from Central Asia over 6,000 years ago. The use of garlic as a food and medicine dates back to prehistoric time. In Korean legend, a female bear lived on garlic and mugwort for twenty days to become a woman almost 5,000 years ago. A record in Egyptian papyrus written around 1,500 B.C. noted the use of garlic for 22 ailments. Egyptians also fed garlic to slaves building the pyramids to increase their stamina. The history of garlic in China also reaches prehistoric time. Garlic has been widely in use in Europe through Middle Ages against ailments and plagues. Folklore touted garlic as repellent of vampires and protector against devils and nymphs. And of course, garlic has been used as an aphrodisiac around the world throughout the ages.
Louis Pasteur demonstrated the anti-bacterial nature of garlic in his report (1858). Garlic was used as an antiseptic for wounds during World War II since penicillin and sulfa drugs were scarce. Americans frowned on garlic until recently, and regarded it only as an ingredient of ethnic foods. What happened now? Americans cosume more than 250 million pounds of garlic each year.

Chemical composition and bioactive compounds of garlic
Chemical composition of garlic bulbs is:
- approximately 60% water,
- 30% carbohydrates,
- 2.3% organosulfur compounds,
- 2% protein (mainly alliinase),
- 1.2% free amino acids (arginine),
- 1.5% fiber,
- 0.15% lipid,
- other micro-components such as phytic acid (0.08%), saponins (0.07%), and beta-sitosterol (0.0015%).
Allicin has been shown to be essential to most health effects of garlic. Garlic contains about 1% alliin, which is converted to allicin by the enzyme alliinase. Anti-microbial potency of allicin gave garlic a nickname “Russina penicillin”, which has been demonstrated against dozens of different bacterial and fungal (including yeast) species. It has been discovered that the main active ingredients of garlic possess antibiotic properties such as polysulfides and it is useful to eliminate the cells of cancer. Garlic has all the essential vitamins required in human diet like ascorbic acid (vitamin C), niacin (vitamin B complex), riboflavin, thiamin etc. It also has vital minerals like iron, phosphorus and calcium. Garlic has been traditionally used for the treatment of althletic foot and vaginal infections, etc.
It has also been discovered that if a person regularly consume a single clove of garlic then it will decrease the severity and frequency of common cold. You may simply crush a single clove of garlic and utilize it just like inhaler in order to get relief from some common ailments including infections, sore throat and stuffy nose. In this way the passages will become clear and also it will combat against the germs. With the help of garlic the yeast infections are decreased because of Candida species plus it also possess anti-oxidant properties. After knowing so many garlic benefits why not to include a single clove of garlic in your regular diet? If you start using it along with your diet then you are going to loose nothing instead you will stay fit forever.

Thousands of research reports on chemical, pharmacological, clinical, and epidemiological studies on garlic were accumulated by the end of last century. Pharmacological and clinical reports can be roughly grouped into following categories:
- anti-microbial effects;
- anti-cancer effects;
- effects on blood sugar levels;
- immune stimulation;
- effects on blood lipids;
