Neem (Azadirachta indica) is the common name of an extremely important tree native to the Indian subcontinent, which now grows in certain parts of the Middle East, as well. The important health benefits of neem leaves include their ability to improve hair and scalp health, soothe irritation, protect the skin, boost the immune system, and reduce inflammation and associated diseases. It also alleviates gastric conditions, slows the aging process, and maintains sexual organ health.

What is Neem?

Neem trees are a part of the mahogany family of trees, Meliaceae. These trees grow very rapidly and have broad-spreading leaves, which they can drop quickly in a drought so as to protect the rest of the trees. This quality makes them extremely resilient to challenging environments; they are primarily found in tropical and subtropical zones. The flowers are very fragrant and white in color, while the fruit of the neem tree is a small drupe with a bittersweet pulp.

Neem leaves are widely sought after, serving as a major industry in the subcontinents – as these valuable leaves can be used for many different things. The oil from the leaves can be extracted and used in a variety of medicines, while the leaves themselves can be dried and used as an herb, or even as a pest repellent. In many areas of India, the shoots and flowers of the tree are also used for culinary applications.

Neem powder contains a unique composition of organic and beneficial compounds, so products derived from it are very popular in herbal remedies. From tea and garnishes to skin salves and herbal supplements, neem is considered as one of the most important and versatile plants in the Indian culture.

Health Benefits

Let’s take a closer look at some of the health benefits of this herb.

Antibacterial Potential

Research published in Evidence-Based Complementary and Alternative Medicine journal notes that one of the most widely recognized benefits of neem powder, oil, leaves, tea, and other derivative is its strong antibacterial and antimicrobial effects. This comes into play both internally and externally, which is why neem is considered to be a general tonic for the immune system and as a simple way to protect your overall health. It is commonly associated with healing skin conditions, but its effects are far more extensive!

Reduces Dandruff

A 2011 study on the medicinal uses of neem suggests that the antifungal and antibacterial properties make it very popular in shampoos and scalp cleansers. This is because it can help the skin remain hydrated and eliminate dandruff while simultaneously strengthening your hair. It also improves the health of your hair follicles due to its antioxidant content. In fact, it is even used in traditional medicines to stimulate hair growth and prevent male-pattern baldness.

Detoxifies the Body

Whether you are using neem powder, paste, leaves, or consuming its extracts in supplements, the active ingredients in this one-stop pharmacy tree will help to rid the body of toxins. Research published in the Journal of Pharmacology and Experimental Therapeutics indicates that neem stimulates the liver, helping eliminate toxins quickly and optimizing the body’s metabolic activities. A great deal of detritus accumulates on our skin every day, including germs, microbes, dust, and grime; neem paste can help neutralize these chemicals, pathogens, or dirt that can cause irritation or illness.

Helps Fight Acne

In terms of acne, neem paste is commonly thought to eliminate much of grease and bacteria that can exacerbate the condition. The antibacterial nature of neem also helps prevent future breakouts, while the antioxidants in it will help minimize scarring and keep the skin looking fresh and clean. It also has astringent properties, which reduces the chances of skin sagging or wrinkles and aging. This is due to the fatty acids in neem oil, as well as the high content of vitamin E.

Improves Gastric Health

Consuming neem has been directly connected with a reduction in inflammation in the gastrointestinal tract, which helps reduce ulcers and a wide range of other intestinal issues, such as constipation, bloating, and cramping. It can also be used as a quick healing antidote for some GI infections that can destroy beneficial bacteria in the gut.

Anticancer Properties

Studies based on animal models indicate that neem extracts may play a pivotal role in anti-cancer management. Research conducted by Mohammad A. Alzohairy showed that neem contains flavonoids and other compounds that assist in reducing inflammatory conditions, and therefore potentially reduce cancer risk. Another study published in the Asian Pacific Journal of Cancer Prevention states that another mechanism of action is that the ethanolic neem leaf extract, which also helps activate the tumor suppressor gene. However, more research in this area is needed to determine the mechanism of action and the impact of neem in a human population.

Exfoliating Properties

When neem paste is applied as a face mask, it works as an excellent exfoliant, shrinking pore size and helping prevent the development of blemishes and pimples.

Inhibits Fungal Infections

You can apply neem powder, neem paste or diluted neem oil directly onto infected areas of the body, including the condition Athlete’s foot. The antifungal effects of its active organic ingredients are rapid and highly efficient, leaving your immune system and skin intact.

Controls Diabetes

As per an animal study published in the Indian Journal of Physiology and Pharmacology, there is a connection between a lower demand for insulin in the body and the consumption of neem. Its chemical components optimize insulin receptor function and ensure that the body is receiving appropriate amounts of insulin, which protects against the development of diabetes. Furthermore, for diabetics, it can be used to minimize the dependence on insulin therapy. However, given the animal nature of these studies, more research in the area is needed.

Fights Malaria

As per a 2009 study in the Malaria Journal, neem acts as a natural mosquito repellant. There has been some unconfirmed research that its leaves can effectively reduce malaria symptoms and minimize the danger of the disease. However, neem’s more common relationship with malaria is as a natural insect repellent that is nontoxic and highly effective in repelling mosquitoes, which are the main vectors of malaria.

Improves Oral Health

Neem is very popular as an ingredient in oral health products in the Indian subcontinent. Its antibacterial qualities make it ideal for eliminating the bacteria beneath the gums that cause periodontal diseases and halitosis (bad breath). Neem is a popular ingredient in mouthwashes and the flavor is not bad either!

Improves Reproductive Health

A collaborative study carried out by the National Institute of Immunology, New Delhi, India and the Contraceptive Research and Development Program (CONRAD) of Eastern Virginia Medical School, Virginia, USA suggests that neem seed extract has spermicidal properties. It is widely used as a natural spermicide and birth control agent, as it is likely to reduce the chances of conception for both men and women without harming them in a toxic way. It lowers fertility levels without impacting libido and can even help prevent certain sexually transmitted diseases.

Anti-inflammatory Agent

As mentioned, there are certain anti-inflammatory properties in neem leaves. This is especially exciting for arthritis research. The paste or oil, when applied to aching joints and muscles due to arthritis can significantly reduce pain and discomfort, and even increase flexibility if consistently used.

Word of Caution: Despite this vast range of potentially beneficial uses, there are some side effects associated with it. Firstly, it should not be used or consumed by infants or toddlers, and those with existing kidney or liver issues should consult a doctor before using any of its components. There is a chance of fatigue, due to its slight sedative nature, so be cautious of overuse, particularly in conjunction with any other medications.
