The neem tree is an all-rounder, possessing innumerable medicinal properties. Most parts of the plant, be it the leaves, root, bark or fruits, are used for its benefits. The extracts from the neem tree produce neem oil, which is another medicinal blessing to humankind. 

Neem oil is acquired from the neem tree, Azadirachta indica Juss. The neem tree is a member of the Meliaceae family and is said to have originated in India. 

Various oil exists in the market, but neem oil stands out prominently. The article highlights the use of neem oil and its role in human health.

What is Neem oil? 

Neem oil, also known as margosa oil, is a vegetable oil. The margosa oil is extracted from the seeds and fruits of the neem, Azadirachta indica, a tree indigenous to the Indian subcontinent that has spread to many other tropical areas. 

Owing to its benefits, neem oil is valued globally as a vital source of phytochemicals. It plays an essential role in human health as well as in pest control. 

What products contain neem oil? 

Margosa or neem oil is the most important commercially available neem product used in organic farming and medicine.

Products containing neem oil are toothpaste, soaps, shampoos for pets and cosmetic products like face creams, body lotions, serum and hair products.

How does neem oil work? 

Neem oil works as an excellent insecticide as well as a good product for the skin. Active components in neem oil, like the Azadirachtin, act as a repellent and reduce insect feeding. 

The component also disrupts insect hormone systems, making it difficult for insects to grow and lay eggs. Azadirachtin can also repel and reduce nematode feeding. Other neem oil components kill insects by interfering with their ability to feed.

Neem oil foliar spray

When applied to a young plant, neem oil works as a foliar spray which has been shown to be most effective. The oil possesses a half-life of 3 to 22 days in soil, but in water, it is only 45 minutes to four days. 

It is almost non-toxic to birds, bees and fish. Studies prove that it does not cause cancer or other diseases. If used correctly, neem oil is extremely safe.

Neem oil insecticide

When applied as a soil drench, neem oil insecticide acts as a systemic in many plants, meaning that the oil is absorbed and distributed throughout the plant’s tissue. 

When the product enters the plant’s vascular system, insects consume it while feeding. 

The compound causes insects to reduce or stop feeding, prevents larvae from maturing and reduces or interrupts mating behaviour. In some cases, the neem oil coats the breathing holes of the insects, thereby killing them.

Uses of neem oil  

The uses of neem oil range from medicinal to the cosmetic industry. Neem oil is available as gels, oils, lotions, shampoos, creams and soaps. The topical application of neem oil can soothe skin issues. 

Treats dry skin and wrinkles 

Neem oil contains vitamin E and essential fatty acids, which allow it to penetrate deep into the skin and heal cracks caused by dryness. 

It also helps to restore the skin’s protective layer, preventing moisture loss. To condition dry skin, applying a mixture of neem carrier oil and coconut oil is suggested.

Who knew neem oil could be such an effective remedy for wrinkles? According to research, it can help stimulate collagen production and improve elasticity, making the skin remain young with age. 

Its high vitamin E content also helps to protect the skin from free radicals.

Stimulate collagen production 

As the skin ages, the production of collagen declines, resulting in the appearance of wrinkles. Neem has high Vitamin C content, which aids in the natural production of collagen and infusing the skin with antioxidants to help smooth fine lines.

Reduce scars 

The high vitamin E in neem oil is also excellent for healing the skin, especially the scars. 

Research suggests that neem oil can help reduce the visibility of scars. It has also been shown to help heal wounds and fade acne scars. Essentially, its skin-healing properties are applaudable.

Treats acne 

Neem oil has anti-fungal, antibacterial and anti-inflammatory properties, which are beneficial in treating acne. 

Given its numerous benefits, neem oil may help prevent breakouts due to its antibacterial properties. 

It also reduces the appearance of breakouts due to its anti-inflammatory properties. This property of neem oil may be beneficial in treating inflammatory acne.
