Rainforests are often referred to as the 'pharmacies of the future' because of the high biodiversity they contain. They hold many medicinal plants and potentially new molecules for drug development.
Rainforests are teeming with plants that have incredible medicinal properties, estimated to number in the tens of thousands of species potentially usable today or tomorrow. Many current treatments for serious diseases like cancer, malaria, or certain heart conditions come directly from plant substances discovered in these forests. The reason? These tropical environments create ideal, humid, and warm conditions for plants to naturally develop hyper-powerful molecules, often defensive, that can become valuable medical remedies. Vines, trees, or even fungi, almost every plant can conceal a future medicine. It’s like a vast natural pharmacy, still largely unexplored.
The biodiversity of tropical forests is a bit like a gigantic toolbox for creating new medicines: the more different plants, insects, or microorganisms you have, the greater your chances of stumbling upon an interesting molecule. Some species naturally produce unique chemical compounds to defend themselves against their enemies or to communicate—exactly the kind of substances that interest pharmaceutical researchers. For example, tropical fungi or certain frogs secrete molecules with antibiotic or anti-cancer properties. The less diversity there is, the fewer chances we have of finding these amazing molecules capable of treating today's complex diseases. Therefore, preserving biodiversity is not just nice for cute animals; it's also a matter of global public health.
Indigenous communities have long possessed valuable expertise on medicinal plants. Their knowledge, passed down from generation to generation, allows scientists to quickly identify plants with promising therapeutic properties. Thanks to this traditional knowledge, several medications currently used against cancer, pain, or infections have been developed. Working in collaboration with local people, while respecting their resources, is therefore essential for the discovery of future innovative treatments.
Rainforests are like a vast open-air lab: they are filled with plants rich in unique chemical compounds, ready to inspire new pharmaceutical molecules. Many current treatments for cancer, malaria, and certain infections come directly from substances derived from these plants. For example, cinchona bark gave us quinine, which was a major weapon against malaria for a long time. Researchers love to explore there because every weird plant may provide leads for creating completely innovative new drugs. Even better, the insects, fungi, and bacteria in these forests also hold incredible potential. In fact, today, more than a quarter of modern medicines already come directly or indirectly from species related to rainforests!
When we clear a rainforest, we erase a ton of potential medicinal molecules without ever having studied them. Protecting rainforests is therefore not just an ecological issue: it is a matter of global health, for today as well as for tomorrow. Without these ecosystems, research loses an incredible natural reservoir for uncovering the medicines of tomorrow against serious diseases, ranging from cancer to new drug-resistant infections. Preserving these forests becomes crucial if we want to avoid missing out on major discoveries for our future well-being.
About 25% of all modern medicines come from substances discovered in rainforests, although only 1% of the plant species that live there have been scientifically examined to date.
Quinine, which for a long time was the main treatment for malaria, is derived from the bark of the cinchona tree, native to the tropical forests of South America.
Indigenous peoples living in rainforests often possess detailed medical knowledge based on generations of experiences and empirical observations, which is still widely regarded as underutilized by modern science.
Every minute, several hectares of rainforest are destroyed, leading to the irrevocable loss of potentially useful plants for future medicine before they can even be studied.
To support conservation, we can consume products from fair trade and supply chains committed to sustainable practices, financially support serious environmental organizations, reduce our daily ecological footprint, and raise awareness among our loved ones about the crucial role of rainforests for our collective health and medical future.
High biodiversity means an abundance of unique plant and animal species. Each organism potentially possesses chemical compounds that are still unknown and could be used to develop new medications for medically complex diseases.
Indigenous peoples possess valuable knowledge about the medicinal properties of tropical plants, accumulated over generations. Researchers often collaborate with these communities, leveraging their ancestral knowledge to quickly identify plant resources that may have high therapeutic potential.
Among the iconic medications derived from tropical plants, we find quinine (derived from the bark of the Cinchona tree) used to combat malaria, vincristine and vinblastine (derived from the Madagascar periwinkle) used in cancer chemotherapy, as well as curare, which was initially used by indigenous peoples as a poison and later became an essential muscle relaxant in surgical anesthesia.
The rapid degradation of tropical forests threatens the survival of many plant and animal species yet to be discovered, which may harbor promising therapeutic molecules. Their gradual destruction leads to the irreversible loss of opportunities to develop future medications capable of treating difficult or currently incurable diseases.
It is estimated that nearly 25 to 50% of currently prescribed medications come directly or indirectly from the plants of tropical forests. These forests are therefore a key resource for present and future medical treatments.
