Abstract:

Garlic is one of the important bulb crops
grown and used as a spice or a condiment throughout India. According to the
Unani and Ayurvedic systems as practised in India, garlic is carminative and is
a gastric stimulant and thus help in digestion and absorption of food. Allicin
present in aquous extract of garlic reduces cholesterol concentration in human
blood. Garlic extract has antimicrobial activity against many genera of bacteria,
fungi and viruses. Garlic contains a higher concentration of sulfur compounds
which are responsible for its medicinal effects. The chemical constituents of
garlic have also been investigated for treatment of cardiovascular disease,
cancer, diabetes, blood pressure, atherosclerosis and hyperlipidaemia and
highly praised by several authors. Therefore, this paper is reviewed to inspire
and impress the young researchers about the medicinal values of garlic. The
inhalation of garlic oil or garlic juice has generally been recommended by
doctors in case of pulmonary tuberculosis, rheumatism, sterility, impotency,
cough and red eyes. Garlic possesses insecticidal action. About 1% garlic
extract gives protection against mosquitoes for 8 hours. Extract of garlic
along with chilli and ginger has beneficial action against soil nematodes.
Beneficial use of garlic extract has been found against many fungi. Garlic is
probably one of the earliest known medicinal plants, which used from ancient
time to cure different disease conditions in human. Garlic’s principal
medicinal uses are to lower blood pressure and cholesterol, fight infections,
and prevent cancer. The main interest of researchers in the medicinal values of
garlic is its broad-spectrum therapeutic effect with minimal toxicity. Garlic
extract has antimicrobial activity against many genera of bacteria, fungi and
viruses. Garlic contains a higher concentration of lavoura compounds which are
responsible for its medicinal effects. The active constituents are  avoura-containing compounds that are rapidly
absorbed and metabolized. Numerous studies suggest that garlic lowers total
cholesterol concentrations by approximately 10%, favorably altering HDL/LDL
ratios. Literature survey support garlic’s effectiveness as a mild
antihypertensive, lowering blood pressure by 5-7%. Garlic inhibits platelet
aggregation and enhances fibrinolytic activity, reducing clots on damaged
endothelium. Another important use of garlic is as antidiabetic. Garlic
controls the blood sugar level by different types of mechanisms. In vitro
studies and animal data suggest that garlic may help to prevent some solid
tumors. Therefore garlic is also effective in the cancer prevention. There are
no studies evaluating its effectiveness in treating children or pregnant or
nursing women. The other proposed uses of garlic include the hepatoprotective,
antihelmentics, anti-inflammatory, antioxidant, antifungal and wound healing.
Garlic, from crushed to capsules, is consumed throughout the world. The active
chemical in garlic is allicin, which is produced when raw garlic is crushed,
allowing the enzyme alliinase to act on the stable precursor allin. Garlic’s
antidiabetic, antibiotic and perhaps anticancer effects are well accepted in
the world over, because of the many scientific literature supporting these
effects. Garlic also has hepatoprotective, antioxidant, and antihelmentic
effect. This review paper demonstrated some of the benefits of garlic for its
potential uses in preventing and curing different diseases, and acting as
antioxidant for many radicals. Fresh and powdered garlic are popular for food
flavor and should continue to be used. Today, with the ever-growing resistant
organisms, taking of garlic extract remains a powerful antimicrobial agent. Clearly
more studies are needed to refine the use and improvement of the efficacy of
this important medicinal plant. It is corresponding that substitute medicines
practices with plant extracts including garlic as a means of decreasing the
burden of diseases would be of public health importance.
