I am now considered by many as the expert on creating allergy-free and allergy-friendly gardens and landscapes. I have lectured on the subject all across the US and Canada, and also in Israel, Ireland, the United Kingdom, New Zealand, and Australia. For 30+ years now I’ve been researching the connections between urban landscaping and allergies and asthma. My articles have appeared in dozens of fine publications, including The New York Times, The London Times, The Guardian, The Los Angeles Times, Atlas Obscura, Scientific American, Der Spiegel, and The New Scientist. I have owned two nurseries and taught horticulture for twenty years.

The Allergy-Fighting Garden: Stop Asthma and Allergies with Smart Landscaping
This is the best book on medical botany. The authors are both top experts on biology and botany, and among his peers in biology, Walter H. Lewis is known as the medical botanist. Just packed with interesting, useful information not found anywhere else. Widely used as a university textbook for medical botany…but extremely readable. Highly recommended!
Plants as Medicine.... A Natural Approach to Self-Health Medical Botany: Plants Affecting Man?s Health, Walter H. Lewis, Memory P.F. Elvin-Lewis
Medical Botany is a fascinating look at the facts and fictions surrounding plants and man?not only which plants affect our bodies, but how they affect them. Authoritative, rich in anecdote and lore, lavishly illustrated, this encyclopedic reference brings within your reach the curative, healing, poisonous, allergenic, and psychoactive properties of thousands of plants. Its ready reference format allows you to turn instantly to information about a specific plant?s properties, its history, its use in orthodox medicine (where applicable) and its…
Edited by Matilda van den Bosch and William Bird, Nature and Public Health. Each chapter was written by several top experts in the field. There were more than a hundred different experts chosen to write sections of this fine book, selected from all around the world of health, botany, horticulture, urban forestry, urban affairs, and the environment. Nature (or the lack of it) is closely aligned with human health, and this wonderful book explores the subject like no other.
Human beings have always been affected by their surroundings. There are various health benefits linked to being able to access to nature; including increased physical activity, stress recovery, and the stimulation of child cognitive development. The Oxford Textbook of Nature and Public Health provides a broad and inclusive picture of the relationship between our own health and the natural environment. All aspects of this unique relationship are covered, ranging from disease prevention through physical activity in green spaces to innovative ecosystem services, such as climate change adaptation by urban trees. Potential hazardous consequences are also discussed including natural disasters, vector-borne…
Airborne and Allergenic Pollen of North America was the most important book I read (out of hundreds) when I was doing my original research for my own book. The material is extensive, accurate, scientific, and yet it is quite readable. Unlike so many other books, papers, or articles on pollen and allergy, this book takes into consideration all of the plants grown in North America, not just the trees. A classic, and yet, still the very best.
I own hundreds of books on plants and trees. The two finest books written on American trees were both written by Donald Culross Peattie. His book on Western trees is amazing. When he looks at and writes about a particular tree, he mentions everything about it. What it looks like, where it grows, how big it gets, what it is used for, what animals, birds, insects use this tree. He also mentions in detail how it flowers, sets seeds, grows….he misses next to nothing. Totally recommended!
A lovely reprint of Peattie's 1950 classic with the fine wood engravings and a new (4 page) introduction by Robert Finch. This editio printed on alkaline paper. Annotation copyright Book News, Inc. Portland, Or.
A Natural History of Trees of Eastern and Central North America by author and naturalist Donald Culross Peattie is probably the very best book on trees that I have ever read. I used this book (and also his book on Western trees) as a marvelous resource when I was working on my books.
I learned many a new thing from this book, things I could not find in books written by botanists or horticulturists. This in large part is because Peattie was first and foremost, a naturalist. He tells the reader things that others didn’t bother to mention (for example, that with Honeylocust trees, each branch is of only one sex). The author also has a wonderful way of writing that makes the text come alive…always interesting. As a naturalist, Peattie looks at the whole picture; one of the few writers about trees who was also a dedicated ecologist. A great book!
Many allergies (and asthma) are homegrown…caused by plants growing right in your own yards. Learn which choices are the most allergy-free, and which are the worst. Thousands of trees, grasses, ground covers, vines, and shrubs are included…and all are ranked 1-10 (where 1 is the best, and 10 is the worst, the most allergenic. Used by hundreds of cities worldwide.
I have been to, and loved, North, Central, and especially East Africa for over fifty years. Only six times have I been to Africa on holiday; more often, perhaps twenty or more times, as a television producer. Working in Africa gains a perspective of reality that the glories of vacation do not. Each has its place, each its pitfalls like stalled plane rides with emergency landings in the bush or attacks by wildlife. But, in the end, the magic of the “otherness,” what an old friend called “primitava” captures one’s soul and changes your life.
Keen to rekindle their love of East African wildlife adventures after years of filming, extreme dangers, and rescues, producer Pero Baltazar, safari guide Mbuno Waliangulu, and Nancy Breiton, camerawoman, undertake a filming walking adventure north of Lake Rudolf, crossing from Kenya into Ethiopia along the Omo River, following a herd of elephant making their annual migration.
Stumbling onto an elephant poaching, the team become embroiled in true financing of terrorism for al Shabaab –ivory sales–and are determined to stop the slaughter at any cost. Ivory trade financing terrorism involves UN refugee camps with two hundred thousand displaced Somali persons, powerful…
A documentary team hiking through East Africa collides with a gang of deadly poachers, in this gripping adventure by the author of Kidnapped on Safari.
Years of filming, extreme dangers, and daring rescues have taken their toll on documentary producer Pero Baltazar and his team. To relax and reconnect with the East African wildlife they love, Pero organizes a walking safari for him, his camerawoman Nancy Breiton, and their elite guide Mbuno Waliangulu. Still, Pero has trouble truly disconnecting from work. When the team comes across a herd of elephants making their annual migration north of Lake Rudolf, Pero decides…
