Do you love wandering around you garden looking at your trees, bushes, plants and wonder what use they might have? Of course, the turnips, runner beans et cetera on your vegetable patch you know that they are good for you. But what about marigolds, dandelions, marsh mallow, acorns, pine needles? Yes, they are all edible one way or another. And going for a ramble in the Countryside? There are many wild plants, shrubs and trees that have some part that is edible. But be careful and know exactly what it is you are picking. There are two umbiliferae that you need to be aware of. Cow parsley is edible but the plant is very similar in appearance to Hemlock, which if ingested can kill you. Also, do you know which plants contain ingredients that can be made into health boosters or medicine? A surprising number, but not all of these are edible. Many plants are toxic to humans, although some contain ingredients which can be made into medicines. This book surveys over 600 plant species which were compiled into a comprehensive data-base, from which tables were constructed in the book for easy reference. Common names are given against their Botanical names. Flowers were grouped by their petal numbers. The use of each plant was recorded: is it edible, does it have health benefits, is it toxic? A very useful compendium of plant species for all plant lovers. The book is illustrated with numerous colour images of various flowers and plants.Zum Buch

Dengue fever is a viral illness transmitted primarily by mosquitoes, particularly the Aedes aegypti and Aedes albopictus species. It is widespread in tropical and subtropical regions of the world, affecting millions of people each year. Despite significant efforts to combat the disease, dengue continues to pose a major public health threat, especially in densely populated urban areas. The virus, which is transmitted when an infected mosquito bites a person, causes symptoms that range from mild flu-like signs to severe and potentially fatal complications, including dengue hemorrhagic fever and dengue shock syndrome. These complications can be life-threatening and often require immediate medical intervention. While there is no specific antiviral treatment for dengue, medical care focuses on managing symptoms and preventing complications, especially during severe cases. The availability of a vaccine for dengue, though promising, has had mixed results and is not universally accessible or suitable for all individuals. As such, prevention remains the cornerstone of dengue control. The best ways to protect against the virus include reducing mosquito exposure, controlling mosquito populations, and implementing preventive measures such as using insect repellent, wearing protective clothing, and eliminating breeding sites for mosquitoes. In recent years, there has been a growing interest in natural remedies and alternative treatments for managing dengue fever. While conventional medical treatments are essential, many individuals seek complementary approaches to support the body’s natural healing processes, enhance immunity, and alleviate symptoms. This book aims to provide an in-depth exploration of both conventional and natural strategies for preventing and treating dengue fever, with a particular focus on natural remedies for symptom relief, immune support, and overall recovery.Zum Buch

Is the human body built for Mars? NASA's studies on the International Space Station show we need to fix a few things before sending people to the Red Planet. Astronauts go into space with good vision and come back needing eyeglasses. Cognition and DNA expression could be affected for years. And then there's the discomfort of living in a tight space with crewmates, depression, and separation from the people you love. Space doctors are on the case. You'll meet the first twin to spend a year in space, the woman who racked up three physically challenging spacewalks in between 320 days of confinement, and the cosmonaut who was temporarily stranded on space station Mir while the Soviet Union broke up underneath him. What are we learning about the human body? As astronauts target moon missions and eventual landings on Mars, one of the major questions is how the human body will behave in "partial gravity." How does the human body change on another world, as opposed to floating freely in microgravity? What can studies on Earth and in space tell us about planetary exploration? These questions will be important to the future of space exploration and to related studies of seniors and people with reduced mobility on Earth.Zum Buch
