Ed. note: Selena Ahmed, ethnobotanist and author of the gorgeous new book Tea Horse Road will be at the Garden for a book signing this Saturday, May 21 at 3 p.m at Shop in the Garden. I first saw Selena’s book in a colleague’s office. The absolutely stunning photographs, taken by Michael Freedman, drew me in, but it is Selena’s tales that bring this fascinating book to life. We are currently working with Michael, who is traveling China, to put together a post of his photographs, so stay tuned. But why wait? Pick up a copy of Tea Horse Road this Saturday. You won’t be disappointed.

My new book, Tea Horse Road: China’s Ancient Trade Road to Tibet, with photographer Michael Freeman explores lives and landscapes along the world’s oldest tea trading route. Our journey starts in tropical montane forests in China’s southern Yunnan Province. This is the birthplace of the tea plant, Camellia sinensis (Theaceae). The cultural groups of Yunnan including the Bulang, Akha have produced and consumed tea for centuries for its well-being and stimulant properties. They traditionally grew tea plants as trees of several meters tall without the use of chemical fertilizers, pesticides and herbicides.

While tea cultivation spread where climatic conditions allowed, the practice of drinking tea reached far beyond. During the 7th century, the Tibetan kingdom to the north of Yunnan came into contact with tea, and the drink soon became central to the Tibetan people’s diet. Tea functioned to reduce the oxidative stress of Tibet’s high altitudes and as a dietary supplement in an environment with limited fruit and vegetable production. These same extreme conditions mean that tea has remained an imported item from tropical and sub-tropical areas in China’s Yunnan and Sichuan provinces. The demand for tea led to the creation of a network of trails extending more than 3,000 kilometers, carved through forests and mountains, with Lhasa at its core. This network collectively became known as the South West Silk Road or Cha Ma Dao, the Tea Horse Road.

However, tea was only one side of the trade equation: China was in constant search for warhorses that made its armies more mobile allowing the kingdom to maintain control over the empire. Abundant natural resources along with tea and horses were exchanged on the Tea Horse Road over the course of 2 millennia, linking cultures and natural resources beyond their surroundings. In its day, the Tea Horse Road touched the lives of many. These were the tea farmers on the southern mountains, the caravan leaders, the Tibetan lados skilled at traversing high passes and the porters with 100-kilo loads on their backs. This book is their story, narrated against the backdrop of some of the world’s most rugged and powerful landscapes.

Trade along the Tea Horse Road declined in the 20th century as horses ceased to have a major military use. Roads were paved allowing for more efficient transport, and policies and markets transitioned. As the Tea Horse Road acquires a historical presence, it is easy to forget its vital former role of maintaining community health, sustainable agriculture, livelihoods, and cultural exchange.

The research for my new book, Tea Horse Road: China’s Ancient Trade Road to Tibet, is partly based on my doctoral study at The New York Botanical Garden supervised by Dr. Charles M. Peters and guided by NYBG curators Drs. Amy Litt, Michael Balick, and Christine Padoch. My goal for this book was to disseminate findings from my doctoral study to a wide audience. The narrative is accompanied by Michael Freeman’s stunning visual documentation and is published by River Books.

An Ethno-what? It’s an all too common question for New York Botanical Garden Research Specialist Ina Vandebroek. Ethnobotany is a field many people take for granted and Ina finds that just saying “I work with plants” doesn’t quite explain it. Traveling the Caribbean, Ina has worked with local communities to document how plants have been and continue to be used medicinally. We took a quick visit to the Enid A. Haupt Conservatory with Ina, where many Caribbean specimens are on display during The Caribbean Garden.

“Medicinal plants are a source for a lot of today’s pharmaceutical medicines,” said Vandebroek. ”In a lot of places around the world people use plants as their only and first form of health care, so basically what ethnobotanists do is we go out to these remote places and we study how people use plants.”

Despite the fact humans have been using plants since the dawn of time, when thinking of ethnobotany many find it hard to get past the ideas of beat-influence Richard Schultes and Sean Connory’s rugged grey ponytail in the film Medicine Man. “It’s so much more than hallucinogenics and finding the next cure for cancer,” Ina said, laughing. “Its about helping communities that are really in need. We try to promote it as a science that can help local communities in conservation of their bio-cultural diversity.”

Ina’s current focus is on the flora of the Dominican Republic. She works not only in the Caribbean, but here in New York City with Dominican immigrants, frequenting many Botanicas.”We try to give those results back to them in the form of guides books as well as workshops within the community. We can also have programs together with universities to isolate bioactive compounds and those could lead to new medicines for humankind.”

Here’s a quick video about Ina’s thoughts on ethnobotany and a few of her favorite Caribbean plants on display now in the Conservatory.

NYBG Student Travels to Asia to Trace Eggplant’s Roots

Rachel Meyer, a doctoral candidate at the Botanical Garden, specializes in the study of the eggplant’s domestication history and the diversity of culinary and health-beneficial qualities among heirloom eggplant varieties. She will hold informal conversations about her work at The Edible Garden‘s Café Scientifique on September 13.

The eggplant (Solanum spp.) may not seem like the world’s most exciting food crop at first thought, but its history and diversity are actually quite intriguing. The common name, “eggplant,” actually covers more than one species, whose size, shape, color, and flavor are remarkably different throughout the world.

People have grown eggplants for over 2,000 years in Asia, and it is thought that eggplants were used as medicine before being selected over time to become a food. Many present-day cultivars of eggplants still contain medicinally potent chemical compounds, including antioxidant, aromatic, and antihypertensive, some of which might be the same compounds responsible for flavor as well.

If we can unravel the history of the eggplant’s domestication and investigate the health-beneficial and gastronomic qualities of heirloom eggplant varieties, we can promote specific varieties that may be useful to small-scale farmers, practitioners of alternative medicine, and eggplant lovers around the world.

I spent seven weeks in China and the Philippines last winter exploring how different ethnic groups use local eggplant varieties. These regions in Asia are important, because scientists are still not sure where eggplants were first domesticated (that is, selected by people over generations for desirable qualities instead of just harvested from the wild). We know it was in tropical Asia, but the written record doesn’t go back far enough to provide more clues. For that reason I also collected wild relatives of eggplant that might be the ancestor of the domesticated crop. read more »
