Neem is the popular name of a tree native to India and widely cultivated in the Indian subcontinent, some parts of the Middle East, and many tropical and subtropical countries. The plant’s scientific name is Azadirachta indica, a part of the family of mahogany trees. Neem is a fast-growing tree with broad leaves that quickly drop in drought as a method of survival. The tree grows resiliently in subtropical and tropical areas.
The plant holds a major importance in the culture of India. For 5000 years, the people of India have used all parts of neem trees, including the leaves, seeds, bark, roots, and flowers, as ingredients of the Ayurvedic traditional treatment.
Neem leaves are important in the culinary and herbal world of Indian culture. They are very versatile as you can use them to make natural skin salves, foods’ garnishes, and herbal tea. Sometimes, the leaves are also dried and consumed as an herb or extracted to create a powerful medicinal oil.
Neem leaves have a wide range of benefits is due to the richness and uniqueness of organic compounds that compose the leaves. A single leaf contains an at least 130 kinds of bioactive compounds, one of the most beneficial appear to be a tetranortriterpenoid named nimbidin. Nimbidin has a large variety of herbal and medicinal properties. A group of researchers from India undertook a scientific literature review on the subjects of neem as a medicinal plant. Their review was published in the journal Current Science in June 2002, discussing the medicinal potentials of nimbidin. The team reported that nimbidin is anti-microbial, anti-inflammatory, hypoglycemic, spermicidal, and antipyretic. Besides nimbidin, there are also nimbin, sodium nimbidate, and nimbodine. Those compounds hold major medical significance, too. Nimbin, for example, possesses spermicidal properties, while sodium nambidate is a very powerful anti-inflammatory agent and nimbolide has antimalarial and antibacterial properties. These bioactive compounds make neem leaves a powerful herb for many medicinal purposes.
Let’s take a look at 15 of the major health benefits of neem leaves

The bioactive compounds nimbidin and nimbolide are very powerful agents that can easily destroy bacteria. In the beginning of 1990s, Noel Viermeyer, Ph.D., led a team of researchers to study the medicinal properties of neem. The result was published in the report titled “Neem: A Tree for Solving Global Problems,” discussing the potential of the plant as a medicine for various ailments, but not for pathogenic bacteria control.
However, another study that was completed and published in the 2011 issue of the journal “International Research Journal of Applied and Basic Sciences” disproved this claim. The study demonstrated how the juice of neem leaf possesses strong suppressant properties against different types of bacteria. In the study, the researchers used Staphylococcus aureus and Salmonella typhosa to test the effectiveness of neem leaf juice. Both bacteria are responsible for dangerous illnesses that are widespread around the world. The test showed positive results on the effectiveness of neem leaves to eradicate bacteria.
The positive effects are due to the existence of nimbidin and nimbolide in the leaves. Actually, most parts of neem possess antibacterial properties, but the leaves have the strongest effects.
