Pandemics and Traditional Plant-Based Remedies. A Historical-Botanical Review in the Era of COVID19. Introduction Pandemics have shaped the history of mankind, and plants were usually the first available therapeutic choice.

Pandemics and Traditional Plant-Based Remedies. A Historical-Botanical Review in the Era of COVID19

There is evidence of herbal preparations by Egyptians around 1500 BC, later improved by Greeks and Romans, and widely documented in official drug books known as Pharmacopoeias. Still in our days, traditional medicines based mostly on plants are the only therapeutic possibility for many people in developing countries (Akerele, 1993). But, also in the first world, with wide access to the most modern drugs, the use of plant-based traditional medicine is experiencing a revival, as it is seen as safer and healthier than synthetic drugs. Indeed, one advantage of traditional remedies over modern drugs is that their effects and margin of safety have been known for long.

Plant Architecture and Its Evolutionary Implications. Another interesting finding borne from these models is that there doesn't seem to be strong correlations between architecture and phylogeny.

Plant Architecture and Its Evolutionary Implications

Although species within a specific genus often share similar architecture, there are plenty of exceptions. What's more, the same form can occur in unrelated species. For instance, Aubréville's model occurs in at least 19 different families. Similarly, the family Icacinaceae, which contains somewhere between 300 and 400 species, exhibits at least 7 of the different models. Alternatively, some families are architecturally quite simple.

How Woody Vines Do the Twist

These strange stem variations give the vines an advantage. “Being asymmetrical helps you to anchor in the trees you’re growing on,” said Marcelo Rodrigo Pace, a botanist at Universidad Nacional Autónoma de México and a co-author of the study. “These lianas also have tendrils that let them grab pieces of stems and leaves and start growing.” The botany in Obama's official portrait represents his history. Ink Foraging in Central Park. On a recent drizzly Tuesday morning, a small group of ink enthusiasts—already rain-slicked, under umbrellas and ponchos—stood on Gapstow Bridge, in Central Park, admiring a brilliant-pink pokeweed bush.

Ink Foraging in Central Park

The Park was the first stop on a five-hour foraging trip that would take them up to Hudson Heights, to collect foliage and trash, which they would cook, to make ink. Their guide, Jason Logan, the founder of the Toronto Ink Company, was in town for the launch of his book, “Make Ink: A Forager’s Guide to Natural Inkmaking.” At a reading in the West Village, he had asked the audience if anyone wanted to go foraging. The city offers some attractive ingredients: acorns, wild grapevines, beer caps, feathers, subway soot. Logan, who is forty-six, became interested in ink about twenty years ago, when he was living in New York, working as an illustrator for newspapers and magazines. Tiny Chinese seaweed is oldest green plant fossil ever found. Scientists have found in rocks from northern China what may be the oldest fossils of a green plant ever found: tiny seaweed that carpeted areas of the seafloor 1bn years ago and were part of a primordial revolution among life on Earth.

Tiny Chinese seaweed is oldest green plant fossil ever found

Researchers on Monday said the plant, called Proterocladus antiquus, was about the size of a rice grain and boasted numerous thin branches, thriving in shallow water while attached to the seafloor with a root-like structure. It may seem small, but Proterocladus – a form of green algae – was one of the largest organisms of its time, sharing the seas mainly with bacteria and other microbes.

It engaged in photosynthesis, transforming energy from sunlight into chemical energy and producing oxygen. Earth’s biosphere depends heavily on plants for food and oxygen. The first land plants, thought to be descendents of green seaweeds, appeared about 450m years ago. Plant of the Month: Heliconia. Even among spectacular tropical beauties, heliconias stand out.

Plant of the Month: Heliconia

Native mostly to Central and South America, this iconic herbaceous plant has been carried by horticulturalists and plant lovers around the world. Heliconia’s sculptural bracts and stunning colors (reds, oranges, and yellows) have also captivated botanical artists. A painting of two heliconias in the Dumbarton Oaks Rare Book collection by the artist Margaret Mee showcases their distinctive shape and employs the opaque medium of gouache to convey their vibrant color.

Mee was intimately familiar with her subject. It’s Called ‘Plant-Based,’ Look It Up. The terms “vegan” and “plant-based” are often used interchangeably, but there’s a growing effort to define just what it means to follow a plant-based lifestyle.

It’s Called ‘Plant-Based,’ Look It Up

According to Brian Wendel, the founder of the “plant-based living” website Forks Over Knives, going plant-based is often “for people who are very enthusiastic about the health angle” of eating mainly whole plant foods. Reynolde Jordan, who runs a food blog called Plant-Based Vibe in Memphis, said it’s also a way to distance oneself from the rigid ideology of veganism, which calls for abstaining from animal products of all kinds. “When you classify yourself as vegan, you’re now being watched,” said Mr. Jordan, who posts vegan recipes for dishes such as Cajun seaweed gumbo and raw beet balls along with photos of the vegetarian meals he orders on trips. “In my DMs, I’d get all these messages from activists for protests.

Plant Records: The world's most common group of plants is...

How do scientists group plants? In reality, whatever way they like, so long as it’s a useful classification. But if you come up with a group like ‘rare plants’ then you’d be hard-pressed to find a taxonomist who takes it seriously. Scientists tend to like their categories monophyletic. This means coming from a common ancestor. Sometimes paraphyletic groups are useful.

The Mesmerizing Microscopy of Trees: Otherworldly Images Revealing the Cellular Structure of Wood Specimens. After a recent march in D.C., where I walked Walt Whitman’s love of democracy and his conviction that “America, if eligible at all to downfall and ruin, is eligible within herself, not without,” I set out to temper the tumult of the human world with an immersion in Whitman’s other great love — the natural world.

The Mesmerizing Microscopy of Trees: Otherworldly Images Revealing the Cellular Structure of Wood Specimens

Visiting the National Museum of Natural History’s Objects of Wonder exhibition, a splendid embodiment of Whitman’s admiration of the character of trees stopped me up short: a display of slides revealing the cellular structure of trees and shrubs seen under a microscope — stunning images that occupy the lacuna between art and science, resembling ancient tapestries and Klimt paintings and galactic constellations.

The Seedy World of Plant Poaching. In September 2012, two conservation officers with the Ontario Ministry of Natural Resources were waiting along a dirt road in rural south-central Ontario for the poachers to emerge from the forest. The summer before, officers patrolling the area had stumbled upon a poached patch of wild American ginseng after noticing shallow holes pockmarking the ground next to discarded plants torn of their roots. On the Hunt for Unloved, Unstudied, Yet Super Important Lichen. We arrive at Cupsogue Beach, near the eastern tip of Long Island, in the foggy morning after a long drive from Manhattan.

After an hour scouring the dune scrub, there is no sign of what we’re looking for. “This is the unglamorous job of trying to find something that’s rare,” says James Lendemer, a lichenologist at the New York Botanical Garden in the Bronx. We’re searching for Cladonia submitis, more commonly known as “beach broccoli” — though “commonly known” might be generous. It’s an apparently rare lichen with a restricted range between New Jersey and Rhode Island. Plant Love Stories. Specimen of the day – Atropa belladonna « Herbology Manchester. Specimen of the day – Atropa belladonna Posted on Updated on by Jemma Atropa belladonna, commonly called deadly nightshade, is a herbaceous perennial (which means it lives for over 2 years and its stems die down back to the soil level at the end of the growing season) in the Solanceae family.

This flowering plant produces shiny black berries that are extremely toxic. There is also a second version, Atropa belladonna var. lutea, which produces pale-yellow fruit rather than the iconic black berries. Toxicity. Showy Aster Guide.
