    The Neem Tree, A Botanical Description

    Neem is a fast-growing tree and it can reach a height of 15 to 20 meters with a life span of 150-200 years. It is typically grown in tropical and semi-tropical regions of South Asia. 

    Neem is a small-to-medium sized evergreen tree, with wide and spreading branches. It can tolerate high temperatures as well as poor or degraded soil conditions.

    The young leaves are reddish to purple, while the mature leaves are bright green in color. It has opposite and pinnate leaves.

    They consist of a petiole, lamina, and the base that attaches the leaf to the stem. They may bear two small lateral leaf-like structures known as stipules.

    Neem flowers are white and have fragrance. They are arranged in drooping axillary pannicles.

    Neem fruits are smooth and oval or nearly round in shape. They generally enclose one seed. Sometimes they may contain two or three seeds but this is very rare.

    The neem tree is sometimes confused with the similar looking bakain tree. The bakain tree is also known as Melia azedarach.

    The distinction between neem leaves and bakain leaves are that neem leaves are one pinnate while bakain leaves are two and three pinnate. Fruits of the bakain tree are shaped like miniature apples.

    Neem Oil: General Description

    Neem oil has commercial importance for many reasons. It is used widely to make cosmetic products in Ayurvedic and Siddha medicine products.

    Neem oil is very much like other vegetable oils in composition. It is composed of triglycerides of oleic, stearic, linoleic, and palmitic acids. This is the fatty acid content of neem oil.

    Neem oil is obtained from seeds. The seeds are first broken and the kernels separated. The kernels are then pressed in either industrial expellers or by hand or bullock-operated wooden presses, also called ghanis. The oil yield is sometimes as high as 50 percent of the weight of the kernel.

    This cold-pressed oil is mainly used in lamps, soaps, and other non-edible products. It is generally dark, bitter, and has a strong smell. Unlike most vegetable oils, it contains sulfur compounds.

    The pungent odor is reminiscent of garlic.

    A large oil industry in India extracts the oil remaining in the seed cake using hexane. This solvent-extracted oil is not as high quality as the cold-pressed oil. It is used in certain soaps and consumer products.1

    Purification Of Neem Oil

    Purifying neem oil is an elaborate and costly process at present.

    In one method, the smelly sulfur compounds are distilled off. This frees the oil from both odor and susceptibility to rancidity because it also removes the free fatty acids.

    This process has long been used industrially.

    As an alternative to pressing out the oil, the kernels can be extracted first with alcohol and then with hexane.

    Alcohol removes the bitter and odoriferous compounds and hexane recovers the oil. This stepwise extraction upgrades both the meal and the oil. On the other hand, it requires costly solvents and complex facilities. That is why this method is not preferred mostly.1

    Chemistry Of Neem Oil

    Neem oil contains at least 100 biologically active compounds.

    Among them, the major constituents are triterpenes known as limonoids, the most important being azadirachtin. This compound has a melting point of 160°C and molecular weight of 720 g/mol.

    Other components include meliantriol, nimbin, nimbidin, nimbinin, nimbolides, fatty acids (oleic, stearic, and palmitic), and salannin.8

    Neem Research Studies

    The following are some clinical studies which demonstrate the benefits of neem oil.

    Neem seed oil has anti-oxidant properties.

    Free radical or reactive oxygen species are one of the main culprits in the commencement of various diseases. However, neutralization of free radical activity is one of the important steps in diseases prevention.

    Antioxidants stabilize or deactivate free radicals, often before they attack targets in biological cells. They also play a role in the activation of anti-oxidative enzymes.

    These help control damage caused by free radicals or reactive oxygen species.

    Neem oil and other parts of the neem tree have been reported to have antioxidant activity. They play an important role in disease prevention because of their antioxidant property.9

    Neem oil has anti-cancerous activity.

    Cancer is a multifactorial disease and major health problem worldwide. The alteration of molecular or genetic pathways plays a role in the development and progression of cancer.

    The treatment module based on allopathy is effective in one way. It also shows adverse effects on the normal cells.

    Earlier studies reported that many plants and their constituents demonstrated inhibitory effects on the growth of malignant cells. Modulation of cellular proliferation, apoptosis, tumor suppressor gene, and various other molecular pathways were some of the ways.

    Neem contains flavanoids and various other ingredients that play an important role in the inhibition of cancer development.

    Large numbers of epidemiological studies propose that high flavonoid intake may be correlated with a decreased risk of cancer.

    Neem oil holds various neem limonoids which prevent mutagenic effects of 7,12-dimethylbenz(a)anthracene.
    Nimbolide, a tetranortriterpenoid limonoid, is one of the important contributors to the cytotoxicity
    of neem extracts.

    Isolated compound and chief constituents from neem show a range of activities affecting multiple targets. They also play  a role in the induction of apoptotic cell death in cancer.9

    • Neem oil has anti-inflmmatory activity.9
    • Neem oil has anti-pyretic activity.9
    • Neem oil has analgesic activity.9
    • Neem oil has anti fungal activity.9

    Neem oil has anti bacterial activity. In clinical trials, neem oil suppressed several species of pathogenic bacteria, including the following.

    • Staphylococcus aureus is a common source of food poisoning and many pus-forming disorders (for example, boils and abscesses). This bacterium also causes secondary infections in peritonitis, cystitis and meningitis. Many strains are now resistant to penicillin and other antibiotics, one reason for the widespread occurrence of staphylococcal infections in hospitals.
    • Salmonella typhosa is a much-feared bacterium which lives in food and water. It causes typhoid, food poisoning, and a variety of infections that include blood poisoning and intestinal inflammation.10

    Use neem oil under supervision because some studies reported that in children neem oil poisoning can cause vomiting, acidosis and more.9
