History of Neem Oil

Neem is a fast-growing evergreen tree from the mahogany family Meliaceae that can reach a height of 15-20 meters. The tree is indigenous to the dry forests of south and southeast Asia. It is widely distributed in India, Nepal, Pakistan, Bangladesh, Sri Lanka, Myanmar, Thailand, Malaysia, Indonesia and Iran. But neem is believed to be native to Northeast India, Myanmar & Bangladesh.

The neem tree is the holy tree of the Hindus and is considered a significant component in Ayurvedic and Unani medicine. The leaves, bark, seeds and roots of neem contain various pharmacologically active constituents, which may possess antiseptic, anti-inflammatory, anti-diabetic, antibacterial & antifungal effects.



The bitter seed oil (vegetable, fixed oil) has a solid (garlic-like) odour. It is used to treat skin diseases such as eczema and furuncles and to relieve intestinal worm infections.

Neem Essential Oil (Margosa oil) is obtained by hydrodistillation of the seeds. There is very little information in the literature on neem essential oil; virtually all studies on ‘neem oil’ pertain to the fixed oil of the seeds, which may be obtained by either cold pressing or extraction with various solvents or to essential oils from the leaves or flowers of the neem tree. The essential oil is not used in aromatherapy (Anton C. de Groot, 2016).

Neem oil acts as a skincare ingredient, fertiliser, insect repellent and pesticide. In cosmetics such as nail polish, pure neem oil is used. In south-Asia, a vast amount of neem oil is available and is non-edible. Traditionally, neem oil has been used for lighting purposes, such as fuel in lamps in rural areas. Neem oil is also used on an industrial scale to prepare cosmetics, pharmaceuticals, soaps and other non-edible products. (Muhammad Jahangir Latif, 2020)

Neem Oil Benefits for Skin:

The human body’s skin is one of its most important defensive organs. It performs various functions, including protection, percutaneous absorption & secretory and sensory functions. Dryness, ageing, eczema, acne, pimples, dullness, wrinkles, unpleasant spots, and other issues impact the skin. Environmental factors, such as dust, heavy metal, particulate matter, UV radiation, and others, contribute to skin issues. This sort of skin illness is treated using skin care products. These items include a variety of chemical poisons. Seeds, bark, leaves, berries, roots, rhizomes, seeds, stems, fruits, and flowers are all used to extract essential oils. Antioxidant, anti-inflammatory, antiseptic, emollient, anti-seborrheic, anti-keratolytic, and antibacterial characteristics are found in the essential oils. Each essential oil contains active compounds that have substantial skin-care cosmetic benefits. The components in the herbs have no adverse effects on the skin of the human body but rather provide essential nutrients to the skin. (Sagar N. Ande, 2022)

The fruits and seeds of the neem tree Azadirachta indica are used to make neem oil. Neem oil includes a variety of fatty acids and antioxidants, which are helpful for the skin. The fatty acids palmitic, linoleic, and oleic acids in neem essential oil promote healthy, supple skin. As a result, it is a widely used component in skin care products. According to research, neem oil has medical applications in treating several skin illnesses, such as acne, psoriasis, and eczema, as it has anti-inflammatory, antioxidant, antiseptic, and healing properties. It also possesses anti-ageing properties and aids in treating skin ageing signs such as wrinkles, thickness, and redness. (Sagar N. Ande, 2022)

Regenerative properties of Neem Oil are mainly connected with fatty acid content (e.g., oleic, palmitic and stearic acids) and antioxidant potential. It is considered a convenient and effective plant-derived oil for wound healing. According to a study, topical use of neem oil has shown some effectiveness in treating chronic non-healing wounds. (Maria Letizia Manca, 2021)

Neem Oil Benefits of Face:

Neem oil has been used in skin care since ancient times in popular medicine. It has antioxidant, anti-inflammatory, antibacterial, antifungal and antiparasitic effects. It is also rich in secondary metabolites such as glycerides, fatty acids, sulfur-containing compounds and flavonoids. This oil may neutralise free radicals and reactive oxygen species and reduce the expression of pro-inflammatory agents involved in the inflammatory process. In traditional Indian medicine, it is used for its moisturising, antiaging and regenerative properties (Maria Letizia Manca, 2021)

Acne vulgaris is a common skin disorder with complicated aetiology (set of causes). Papules, pustules, comedone, blackheads, and other skin lesions are common physical manifestations of Acne vulgaris. Natural oils are being utilised increasingly to treat skin conditions since they have fewer adverse effects and are expected to provide benefits. Neem oil has anti-acne benefits. (Adeola Tawakalitu Kola-Mustapha, 2023)

Neem Oil is recognised to have antibacterial and anti-inflammatory characteristics and the capacity to strengthen the immune system]. This offers a helpful justification for the potential topical management of acne and helps to stop lesions from returning, leaving the skin healthy. (Adeola Tawakalitu Kola-Mustapha, 2023)

Natural Oils have natural therapeutic capabilities that can lessen the signs of acne and possibly prevent future breakouts. Neem oil is one of these oils, and it has been used for many years to treat skin issues, including acne. A Study said that neem oil could not only manage acne but also prevent the possibility of melanoma. (Adeola Tawakalitu Kola-Mustapha, 2023) 

Neem Oil Benefits on Hair:

Hair and scalp disorders are common among individuals. Recently, there has been an increasing demand for natural products globally, especially for hair grooming and treating hair disorders. These naturally occurring products are accessible and affordable, perceived to be less toxic and contribute to wellness in an individual. These therapies include the use of herbs, the bark of trees, fruits, and oils, which can be administered topically. (Nkechi Anne Enechukwu, 2022)

Neem or Azadirachta indica or also known as Indian lilac. Neem Oil provides many benefits. Problem scalp conditions, including dandruff and psoriasis, scaling and even hair loss, respond to treatment with Neem shampoo, conditioners, creams, and tinctures. (Yogesh S Kolekar, 2021) Neem oil is also used in product formulations that help control ticks, fleas, and lice. It possesses anti-inflammatory, antioxidant, antiseptic, and healing properties. It also gives the best results for dandruff and hair loss. (PATIL, 2023)

Damaged and overly oily hair appears greasy and sticky-free when treated regularly with this unique plant. (Yogesh S Kolekar, 2021)

Neem Oil for Dandruff:

Dandruff is a condition of the scalp accompanied by abnormal flaking of the scalp skin. About 17-50% of the human population suffers from dandruff. It may occur when the scalp overproduces new cells. An enhanced epidermal proliferation rate causes an accelerated cell movement to the outer skin. In this case, the adhesion between different cells cannot be resolved entirely, and scales appear. Sometimes the overproduction of sebum is associated with this process. The Skin sebum & the oil-soaked scales help to birth micro-organisms. Bacteria & fungi are found in the stratum corneum and hair follicles. It is contagious or severe. But it can be embarrassing and difficult to treat.

Neem’s chemical constituents contain tetranor terpenoid lactones azadirachtin, nimbidin, salanin, and nimbolin-B. Neem oil additionally incorporates nimbolides, oli chinolide-B, and azadiradione. It is commonly used to treat dandruff because it produces antifungal, antibacterial, and ache-relieving compounds that treat and ruff. (Anju Goyal, 2022)

Neem Oil as Insecticide/ Pesticide:

'Pesticide' is the general term for a chemical that kills pests. Pests can be weeds, insects, nuisance rodents, diseases, etc. An insecticide is a type of pesticide. Insecticides kill insects.

Neem Oil is an essential source of phytochemicals for human health and pest control. This oil contains at least 100 biologically active compounds. Among them, the major constituents are triterpenes known as limonoids, the most important being azadirachtin, which appears to cause 90% of the effect on most pests. Neem Oil is one of the least toxic to humans and shows very low toxicity to beneficial organisms, so it is very promising for controlling many pests. Oil has a broad spectrum of action, inhibiting feeding, deregulating growth, altering development and reproduction, suppressing fertility, and disrupting moulting.   (Estefânia V. R. Campos J. L., 2016)

Research shows that two per cent neem oil mixed in coconut oil, when applied to the exposed body parts of human volunteers, provided complete protection for 12 h from the bites of all anopheline mosquito species. The application of neem oil is safe and can be used for protection from malaria in endemic countries. (Sharma VP, 1993)

Another research shows that 2% neem and coconut oil provided 96-100% protection from anopheline mosquitos. Therefore, neem oil can be a personal protection against mosquito bites.  (Sharma SK, 1995)

Neem Oil Cold pressed:

There are several methods to obtain neem oil from the seeds mechanical pressing, supercritical fluid extraction and solvent extraction. The most widely used method to extract neem oil from neem seed is mechanical extraction, but the oil produced by this method has a low price since it is turbid and contains a significant amount of water and metal content. Extraction by supercritical fluid produces an oil with high purity, but the operating and investment cost is high. Compared to the above two methods, solvent extraction has many advantages, like it gives a higher yield and less turbid oil and has a low operating cost. (Rita Awasthi, 2019)

Neem Essential Oil (Margosa oil) is obtained by hydrodistillation of the seeds. There is very little information in the literature on neem essential oil; virtually all studies on ‘neem oil’ pertain to the fixed oil of the seeds, which may be obtained by either cold pressing or extraction with various solvents or to essential oils from the leaves or flowers of the neem tree. The essential oil is not used in aromatherapy(Anton C. de Groot, 2016).
