What Is Neem Oil made from
Neem oil is a natural vegetable oil substance extracted from the seeds and fruits of the neem tree. It is a yellow to brown liquid with a strong, characteristic garlic/sulfur smell and a bitter taste (Oregon State University). Neem oil is rich in fatty acids, such as palmitic, linoleic, and oleic acids, making it valuable for various applications.
For centuries, neem oil has been used as a natural pesticide and a remedy for numerous health conditions. Today, components of neem oil can be found in a wide variety of products, including toothpaste, cosmetics, soaps, and pet shampoos.
Origin and extraction
Neem tree
The neem tree, scientifically known as Azadirachta indica, is a tropical evergreen tree native to the Indian subcontinent. It has been introduced to many other areas in the tropics and is a member of the Meliaceae family. The neem tree is large and fast-growing, and can reach approximately 40 to 80 feet in height.
Oil extraction process
Neem oil is a vegetable oil obtained by cold-pressing the fruits and seeds of the neem tree.
Neem oil extraction starts with collecting ripe neem fruits and seeds. These seeds are then cleaned and processed to remove the outer shell, leaving the neem kernel. The kernels are dried, and then cold-pressed using an oil press to extract the oil. The process of cold pressing helps to preserve the active ingredients of neem oil, making it more effective (Medical News Today).
Composition of Neem oil
Major components
One of the most active components in neem oil is azadirachtin, which serves as a repellent and reduces insect feeding. It also disrupts insect hormone systems, making it challenging for insects to grow and lay eggs. Neem oil also contains various fatty acids, which have anti-inflammatory, antioxidant, and other beneficial properties.
Minor components
In addition to azadirachtin and fatty acids, neem oil consists of other components. The neem tree’s leaves contain protein, carbohydrates, minerals, calcium, phosphorus, vitamin C, carotene, and several amino acids, such as glutamic acid, tyrosine, aspartic acid, alanine, praline, glutamine, and cystine. Neem flowers come with fatty acids like dodecanoic, tetradecanoic, and elcosanic, providing further benefits.
