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.

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.

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.
