A powerful new report released by the Kew Gardens in the United Kingdom reveals that there are currently 28,187 plant species recorded as being of medicinal use throughout the world. In addition, the report revealed that fewer than 16% (4,478) of the species used in plant-based medicines are cited in a medicinal regulatory publication.

Study: 28,187 Plant Species Used as Medicines throughout the World

A powerful new study reminds us that natural medicine was once, and still is, the default medical system on this planet... 

In fact, the use of synthetically produced patent medicines (pharmaceuticals) is a relatively recent development (circa 1870), and should really be called the “alternative medicine” vis-a-vis time-tested, far safer approaches that rely on food, spices, and carefully prepared and administered plant extracts. 

While the lesser developed countries are the primary users of plant medicines, they are used in great abundance throughout the world. Even in countries like Germany where conventional, drug-based medicine is the default approach, about 90% of their population also uses herbal medicines. Even the most pharmaceutically obsessed country in the world, the United States, spent 17 billion dollars on traditional herbal medicines in 2000 alone, and the number has grown steadily since then.

It should be noted that mixing plant-based medicines with pharmaceuticals can be dangerous, and as the report points out, many of these plants contain compounds that can cause harm if taken incorrectly. There is also a problem with misnaming or multiple names for the same plant-based medicines::


The report also pointed out that plants still provide the majority of lead compounds for drug development, with many still being directly extracted from medicinal plants:

“Since 1981, 1,130 new therapeutic agents have been approved for use as pharmaceutical drugs, of which 593 are based on compounds from natural sources. Thirty-eight are derived from medicinal plants [40,41] . Fifteen of the 56 natural drugs registered for the treatment of cancer since 1980 are derived from medicinal plants with a long history of traditional use. For example drugs based on Paclitaxel have been isolated from the yew tree (Taxus spp.), Camptothecin from the happy tree, (Camptotheca acuminata) and Podophyllotoxin from the May apple (Podophyllum hexandrum and P. peltatum).”

In some sense, then, one can consider pharmaceutical medicine “plant-based,” with the difference that their patent-based model almost invariably amplifies the toxic side effects to the patient.

The report also points out that presently, of the 5 drugs developmental specifically to treat the symptoms of Alzheimer’s disease, two are derived from plants:

"Galantamine, from Galanthus (snowdrops), Leucojum (snowflakes) and Narcissus (daffodils), was the first natural product drug to treat dementia symptoms. The second was Rivastigmine, which is chemically derived from physostigmine, an alkaloid from Physostigma venenosum (calabar bean)."

Another study mentioned in the report found that there are a staggering 656 flowering plant species used traditionally for diabetes, representing 437 genera and 111 families. For instance, Metformin, probably the most well known drug for diabetes, was modeled after the anti-diabetic properties of Galega officinalis (goat’s rue). Unfortunately, even when a compound is isolated from a natural plant, it can lose its informational integrity, and may behave more like a chemical than a natural substance embedded within the synergistic context of the whole plant. 
Let's Grow the Evidence Supporting Plant-Based Medicine! 

As many of our readers already know, GreenMedInfo was founded to create a central repository for research on the medicinal benefits of natural substances, including the thousands of plants presently used in culinary and herbal medicine applications. Our Research dashboard contains over 30,000 abstracts accessible through 10,000 separate databases. Our mission is to help the public understand the profound value that plant medicine has in preventing and treating disease:

“One of the greatest if not the greatest triumph of biomedical science today is its role in validating ancient healing modalities that long before the advent of science, and even recorded history itself, were passed down "orally" from generation to generation in the vast body of folkloric medical knowledge that still forms the basis for the majority of the world's primary health care system.

These so-called "natural" or "alternative" modalities, which our species owes its present day survivorship to after eons of dependency on them, are increasingly gaining the attention of men and women in white lab coats intent on unlocking the mysteries of how they work, and in many cases, why they work better than patented, synthetic, chemical-based medications.” [Read full article]

Our goal at is to index 100,000 abstracts demonstrating the value of natural substances in the prevention and treatment of disease. We are an ad-free, user-supported platform. Please consider supporting our project by becoming a member today.

The war on cancer is largely and most a huge fraud and consists of profit motivated GREED. The real low cost or free solutions, such as plant based medicines, diet and lifestyle are denied, suppressed, ignored, or attacked, but the high profit chemo, drugs, and radiation are lifted up and treated as if they are holy and beyond reproach.

There are ZERO double blind studies on natural plant based, diet based, and/or lifestyle based cures for cancer by these organizations. Why is this? The medical industrial complex claims that it would be 'unethical' to do studies on natural anti cancer plants and other holistic Big C modalities, because they don't work. Really? 

How about proving that they don't work, with willing volunteers who agree to take this risk, in one or more studies headed up by natural healers who are experienced with reversing Big C using natural methods and without chemo, drugs or radiation? 

TRUE SCIENCE consists of looking at all potentials, and experimenting with all possible solutions, and not turning any of them down, just because a greed motivated bias or motivation. The medical industrial complex must be maintained to nurture greed at all costs, even if it means the suffering and deaths of millions of people each year.
