For centuries, millions have used various parts of the plant: Neem twigs for cleaning teeth. Neem cream for healing skin disorders.
Neem leaves in the beds, books, grain bins, cupboards and closets to keep away insects. Various parts of the plant have also been used for treatment of ailments like fever, infections and other complaints.
Neem leaf extract substantially increases the state of oxidation in red blood cells
Neem reduces erosion deforestation and controlling the global warming process.
Only in recent years, scientists in the Western countries started believing that this tree could be the source for providing tremendous benefit.
Today, Researchers are saying that Neem could be called “a Wonder Tree" and eventually expect it to benefit everyone on the plant. This tree is expected to usher in a new era in pest control, provide millions with inexpensive medicines, cut down the rate of population growth, reduce erosion, deforestation and control the global warming process. This wonder tree has pesticide, germicidal and medicinal properties, and is capable of solving many problems facing mankind today. The wood is termite resistant and is used for carpentry as well as construction work. These trees grow quickly, thrive on marginal and poor soils, and neutralize soil acidity with its alkaline leaves.
Therefore, an increased commercial plantations and agroforestry involving Neem can enhance the economical potential of this tree with positive and large externalities for pesticides, fertilizers, live stocks, dairying and other value-added products.
Botanical Description and Cultivation
Native to east India and Burma, it grows in much of Southeast Asia and West Africa. The neem tree (Azadirachta indica) is a fast growing (up to twenty feet in three years) tropical evergreen related to mahogany. Outdoors, in locations where temperatures don't drop much below freezing, it may reach up to 50 feet tall. It will grow where rainfall is as little as 18 inches per year and thrives in areas that experience extreme heat of up to 120 degrees F. They are reported to live for up to 200 years.
The tree is often covered in delicate flowers in the early summer. It has a semi-sweet, olive-sized fruit. The seed inside is rich in oil with tremendous medicinal and botanical properties. The oil is easily obtained by pressing the kernels in a juicer. It generally begins bearing fruit at three to five years, and can produce up to 110 lbs. of fruit annually when mature.
Neem is a tropical tree, it must be protected from hard freezes. In northern climates it may be grown in pots with the care and appearance of the more-common ficus tree. Neem makes an ideal indoor plant because it grows well with a minimum of maintenance. For optimum growth, Neem should be placed near a sunny window during the winter and moved outside during summer months. However, they will survive indoors even if they don't receive any natural light at all. Its blooms are small, white flowers with a very sweet, jasmine-like scent. They are relatively heavy feeders, responding to organic fertilizers such as fish emulsion, bone meal and kelp with lush new growth.
Few pests attack the Neem tree and most problems with Neem are directly related to over watering. Several different types of fungal diseases can cause die-back, and slugs that thrive in soggy spaces will eat the bottom leaves of small trees.
High blood pressure, blood clots, high cholesterol levels and arrhythmic heart action are major causes of heart attack. Neem leaf extracts have been shown to reduce clotting, lower blood pressure and cholesterol, slow rapid heartbeat, and inhibit irregularities of the rhythms of the heart. There are also reports that some compounds can produce effects similar to mild sedatives reducing anxiety and other emotional and physical states that can precipitate heart attacks. This may be a calming effect similar to that witnessed with other herbal teas or a psychological result of physiological effects of blood vessel dilation and lower blood pressure.
Hypertension or High blood pressure:
The antihistamine properties of nimbidin in leaf extracts cause blood vessels to dilate and may be responsible for reducing blood pressure. Alcoholic extract of Neem leaf (intravenous) produced a significant and immediate decrease in blood pressure, which lasted for several hours. Another Neem leaf extract, sodium nimbidinate, administered to people with congestive cardiac failure acted successfully as a diuretic.
Neem leaf extracts reduced cholesterol levels significantly in recent studies. Alcoholic extract of Neem leaves reduced serum cholesterol by about 30% beginning two hours after administration and kept the level low for an additional four hours until the test ended.
Neem leaf is a traditional herb for treating diabetes and has been scientifically proven effective in treating and preventing diabetes. Diabetes is an incurable, chronic metabolic disorder that develops when the pancreas can no longer produce sufficient insulin. Blood sugar levels rapidly elevate yet the body is unable to use the energy contained in the sugar leading to weakness and eventually unconsciousness. Diabetes is the leading cause of blindness in people ages 25 to 74, damages nerves, kidneys, the heart and blood vessels and may result in the amputation of limbs.
Oral doses of Neem leaf extracts significantly reduced insulin requirements for non-insulin dependent diabetes. Neem oil has also proven effective and has been able to inhibit increases in blood sugar levels by as much as 45% in test animals.
The Indian government has approved the sale by pharmaceutical companies of Neem tablets for diabetics. (Some of these preparations are really nothing more than powdered Neem leaves.)
Researchers in India, Europe and Japan have now found that polysaccharides and limonoids found in Neem bark, leaves and seed oil reduced tumors and cancers and showed effectiveness against lymphocytic leukemia. In several patents issued in Japan hot water Neem bark extracts showed remarkable effectiveness against several types of tumors. Several of the extracts were equal to or better than the standard anti- cancer agent against solid tumors. Another researcher used an extract of Neem leaves to prevent the adhesion of cancer cells to other cells in the body. Without the ability to stick to other cells, cancers cannot spread through the body and are more easily destroyed by the body's own immune system or by other treatments. In general, Neem is known for its ability to affect cancers. Injections of Neem extract around tumors showed remarkable reduction in size in just a few weeks.
A number of reports have been made by patients that skin cancers have disappeared.
