Download Free The Neem Tree Book in PDF and EPUB Free Download. You can read online The Neem Tree and write the review.

The most comprehensive and best illustrated treatment of the fascinating tropical neem tree (Azadirachta indica) and its unique substances. The extracts from the neem tree have an enormously broad range of applications. The main substance azadirachtin, a tetranortriterpenoid, influences the hormone system of insects, exerting thereby a pesticidal effect. Feeding activity, reproduction and flying ability of insects are also affected. It is biologically degradable and can be easily extracted from the seeds of the tree. Other important uses of neem tree products are: - antifertility and population control - cure of human diseases - manure and nitrification inhibitors - feeds for domestic animals - soap production With its exhaustive treatment of the neem tree and closely related plants, this book provides us with an impressive example of the varied uses of renewable resources.
This comprehensive review on neem is an excellent collation of observations and research efforts by botanists, taxonomists and medical practitioners and will be of interest to everyone with an interest involved in medicinal and aromatic plant research.
Used in India for more than 4,000 years, neem is a powerful blood purifier, anti-viral agent, and immune system enhancer.
The chemicals from plant sources, generally termed as phytochemicals, play an important role in acceptance or rejection of the plant by the pests as they could be distasteful or toxic on one hand or on the other hand specialist herbivores have the capability to feed on many such chemicals, as they are able to process these natural products in a manner that is beneficial to them. In the wake of increasing environmental degradation due to burgeoning synthetic chemicals, there has been a process going on to rediscover the usefulness of plants and herbs and a continued effort for more than 2 decades has been to study the green products for cures for several ailments and pest management. In fact, according to Indian Medicinal Plants: A Sectoral Study, the global trade for medicinal plants amounts to about US $ 60 billion and the world demand continues to grow at the rate of 7 per cent per annum. Although many such plants are known in literature, neem has been one of trees with mani-fold virtues. Indian neem tree, Azadirachta indica A. Juss, which is a large evergreen tree, is an outstanding example among plants that has been subject matter of numerous scientific studies concerning its utilization in medicine, industry and agriculture. So far neem preparations have been evaluated against more than 500 species of insects and more than 400 hundred are reported to be susceptible at different concentrations.
German Canadian Klaus Ferlow was one of the first to introduce the miraculous healing products from the Indian Neem tree to the West. As a teenager he'd developed a stubborn case of psoriasis which was resistant to both conventional and alternative treatments. His life changed 40 years later when he found out about the remarkable healing properties of Neem, a plant that healers in India have used for thousands of years. Within a few weeks Neem had finally freed him of the life-long condition. As a manufacturer of botanicals, Klaus was in the ideal position to develop a variety of Neem products and make them available to the North American market, as early as 1994. The author traces his own healing journey and his lifelong fascination with the versatile Neem tree from Canada to the Indian subcontinent where the tree originated. The book includes a valuable guide to herbs, list many useful healing applications of Neem, and explores its politics and history. The endearing story of the Neem tree is told through the eyes of one of its most enthusiastic advocates. Klaus Ferlow has since established the Neem Research organization to protect and promote this precious healing gift to humanity.
The most comprehensive book about neem, the world's most amazing plant, provides easy-to-understand instructions for using neem along with credible scientific evidence as to its effectiveness.
This book describes the sequencing efforts for Neem (Azadirachta indica A. Juss), one of the most versatile tropical evergreen tree species. The neem tree is a source of various natural products, including the potent biopesticide azadirachtin and limonoids, which have a broad spectrum of activity against insect pests and microbial pathogens. To identify genes and pathways in neem, three neem genomes and several transcriptomes are studied using next-generation sequencing technologies. Neem has been extensively used in Ayurveda, Unani and homoeopathic medicine and is often referred to as the ‘village pharmacy’ by natives due to its wealth of medicinal properties. Besides the description of the genome, this book discusses the neem microbiome and its role in the production of neem metabolites like salanin, nimbin and exopy-azadirachtin under in vitro conditions. It also highlights cell and tissue culture using various neem explants including the leaf, root, shoot, cambium, etc.
Ayurveda is a holistic system of health care that's been practiced in India and Sri Lanka for centuries. Practitioners view patients as a whole person, taking into account both their physical and spiritual well-being, and seek to balance the three bio-energies, or doshas. In the Vedas, neem is called "the one that cures all ills." The most researched therapeutic uses of neem (Azadirachta indica) include its fungicidal, antibacterial, and antiviral properties. Neem is also an effective anti-inflammatory that can help reduce the pain of arthritis and other inflammatory conditions. An herb with countless uses, neem is also used for acne, dental care, heart disease, and diabetes.
Neem is a fascinating tree. On the one hand, it seems to be one of the most promising of all plants and may eventually benefit every person on the planet. Probably no other yields as many strange and varied products or has as many exploitable by-products. Indeed, as foreseen by some scientists, this plant may usher in a new era in pest control, provide millions with inexpensive medicines, cut down the rate of human population growth, and perhaps even reduce erosion, deforestation, and the excessive temperature of an overheated globe.On the other hand, that all remains only a vague promise. Although the enthusiasm may be justified, it is largely founded on empirical or anecdotal evidence. Our purpose here is to marshal the various facts about this little-known species, to help illuminate its future promise, and to speed realization of its potential.This report has been produced by the National Research Council particularly for nonspecialists such as government ministers, research directors, university students, private voluntary organizations, and entrepreneurs.

Leading landscape photographers Diane Cook and Len Jenshel present Wise Trees—a stunning photography book containing more than 50 historical trees with remarkable stories from around the world. Supported by grants from the Expedition Council of the National Geographic Society, Cook and Jenshel spent two years traveling to fifty-nine sites across five continents to photograph some of the world’s most historic and inspirational trees. Trees, they tell us, can live without us, but we cannot live without them. Not only do trees provide us with the oxygen we breathe, food gathered from their branches, and wood for both fuel and shelter, but they have been essential to the spiritual and cultural life of civilizations around the world. From Luna, the Coastal Redwood in California that became an international symbol when activist Julia Butterfly Hill sat for 738 days on a platform nestled in its branches to save it from logging, to the Bodhi Tree, the sacred fig in India that is a direct descendent of the tree under which Buddha attained enlightenment, Cook and Jenshel reveal trees that have impacted and shaped our lives, our traditions, and our feelings about nature. There are also survivor trees, including a camphor tree in Nagasaki that endured the atomic bomb, an American elm in Oklahoma City, and the 9/11 Survivor Tree, a Callery pear at the 9/11 Memorial. All of the trees were carefully selected for their role in human dramas. This project both reflects and inspires awareness of the enduring role of trees in nurturing and sheltering humanity. Photographers, environmentalists, history buffs, and nature-lovers alike will appreciate the extraordinary stories found within the pages of Wise Trees!
