Though they’re technically called neem trees, nymph trees have several benefits, the largest of which is pest control. Because the neem tree controls pests and kills them at their nymph stage, the tree is sometimes nicknamed the nymph tree. Used for more than 4,000 years, the neem tree is used mostly in India and other Asian countries.
The University of Connecticut’s Integrated Pest Management program claims that the seed has the highest level of pesticide. Most over-the-counter pesticides contain azadirachin, which is present in the nymph tree seeds. Azadirachtin is a deterrent against many pests, including beetles. The substance prevents the immature larvae and nymphs from developing into full-sized pests. It doesn’t affect adult pests, but it disrupts their sexual and communication processes, which can be enough to keep the pests away.
People in India have used the twigs of the neem tree to clean their teeth, much as they would use a toothbrush. In addition to the twigs, other parts of the tree are used for traditional medicine, including the seeds, flowers, fruits, bark, roots and leaves. The tree’s extract is found to inhibit the growth of cancer cells, particularly cancer of the breast, colon and prostrate. None of these findings have been recognized in Western medicine, however. The tree, along with turmeric, can help skin disorders, such as scabies and lice. The pesticide power of neem works on humans, too, and kills lice at every stage. This appeals to consumers because most typical lice treatments contain toxic chemicals, yet the nymph or neem tree doesn’t show any negative side-effects.
In addition to medicinal uses, the tree might have some affect on fertility and contraception. An Indian trial is testing whether a blend of neem oil and other herbs can render sperm immobile and act as a natural spermicide. Also, the extract could act as an abortificent if given before a fertilized egg implants into the uterus.
Inclement conditions can affect the nymph or neem tree’s oil’s potency. It is susceptible to temperature, rainfall and ultraviolet light. Several applications of the product could be necessary to achieve desired results. Also, it could negatively affect younger and newly transplanted flowers, according to the Integrated Pest Management Program.
