See stevia's history of varied uses, including as a treatment for burns and indigestion.

The Stepan Company works closely with Coca-Cola so that the soda giant can continue to use coca leaves for its beverages. Today, the cocaine from the coca leaves is removed before they are used to create Coca-Cola.

Silphion: cure-all, aphrodisiac, birth control, tasty seasoning. Nero allegedly ate the last of this miracle plant. This article details how a researcher may have found more. Seven centuries after the yellow-flowered plant was first documented growing in what's now Libya, it vanished. Historians proposed that the loss of Silphion may have been the first recorded extinction of any species.

Once used by the ancient Sumarians—extracted from willow bark—but now synthesized in the lab, the active ingredient of this popular medication has been used to treat headaches and pain for thousands of years.

After centuries of use by Mexican spiritual healers, Salvia divinorum is surging in popularity in the U.S. — and the government has taken notice.

Humanity's ancestors evolved to wring more calories from sugary fruits by storing excess sugar as fat, an adaption that's culminated in many peoples' palettes preferring calorie-rich sweet. Now, the desire for sugar has both contributed to a widespread health crisis and been at the center of atrocities around the world.

Experiments dating back to the 1940s eventually led to the creation and standardization of a mixture of sugar, salt, and clean water that is now widely used globally.

Long after humans developed the means to produce sufficient food to feed civilizations, scientific research focused on a wide variety of objectives, such as developing methods to preserve food quality (accomplished via frozen food), speeding up cooking (leading to the microwave), and lowering the cost of sweetening food, which high fructose corn syrup provides.

Love vanilla-flavored foods? Well, it was once made from castoreum - a yellowish exudate from the castor sacs of mature beavers. And the FDA regards castoreum as “natural flavoring."

There are a few reasons why American Coke turned away from sugar in the 1980s, but none of them are related to consumer health. This Reader's Digest article breaks down the history behind Coke's recipe change, explaining why the company continues using high-fructose cough syrup.

Scientists are trying to figure out if there are unique receptors that respond to the molecules that make up flavors we associate with calcium, blood, batteries, and other items that often escape dinner menus. Taste researcher Dr. Danielle Reed says the minimum evidence for a taste category typically involves identifying dedicated receptors and then removing them to show the taste vanishes.

Developed in 1912 by American pharmacist Wilbur Scoville, the scale is a subjective test in which testers determine the dilution at which capsaicinoids—the molecules that give peppers their heat—are no longer detectable. Modern chemical analyses can accurately quantify the amount of these molecules in peppers, which are diluted to varying degrees in sauces, thus affecting their net spiciness.

The colorful candy combines Indigenous traditions with European confectionery techniques. Its symbolization reminds celebrants that death can be “sweet.”

Religious or medical use of opium was present across Europe and Asia as early as 5000 BCE. By the 16th century, humanity had come to see opium as more than medicine: It was a marketable product. This perspective also defines today's relationship with opioids, highly addictive painkillers at the heart of an ongoing drug crisis.

Receptors for "bitter" tastes evolved to detect potentially harmful plant chemicals, such as nicotine. The receptors also trigger bacteria-fighting responses, including waving hairlike projections to bat away bacteria, ordering the release of bacteria-killing nitric oxide, and calling for antimicrobial protein reinforcements.

Memorial Sloan Kettering Cancer Center has created this searchable resource of herbal supplements to inform the public about the purported uses of herbal therapies, the existing evidence about them, their mechanism of action, and any concerns about potential herbal supplement and drug interactions.

Amid Napoleon's invasion of bitterly cold Russia, soldiers succumbed to frostbite by the thousands. Nineteenth century doctors recommended walking and rubbing snow around the affected area. Fast forward to recent years, and the FDA has approved its first ever drug to treat frostbite. Listen to this podcast to learn the history of this wintry affliction.

Rosemary is more than just an herb—it’s a powerful symbol intertwined with ancient Egypt, Christianity’s origins, Shakespeare, the culinary arts, and more. Native to the Mediterranean area, this plant has accompanied humanity for centuries, providing us with pleasant aroma, adornment, and even medicine. Explore this article for further insight into the significance of our long-standing relationship with rosemary.

The drugs were developed for use treating diabetes and, later, weight loss, but they have proven helpful with the heart, kidneys, and colon. On the flipside, it may slow digestion and lead to gastroparesis, or stomach blockages, and unexpected babies resulting from the slow effect of birth control pills.

Already used to treat type 2 diabetes, the novel medications are showing some early promise in experimental studies at reducing inflammation and treating autoimmune conditions including rheumatoid arthritis and inflammatory bowel conditions. But researchers caution that side effects are still under investigation—rarely the medication has caused lupus, an autoimmune disease.

Blood's importance to humanity is best summarized this way: without it, we die. This importance naturally begets assumptions about its medicinal properties, many of which appear accessible through drinking or eating the fluid connective tissue. This article details the history of blood drinking, from ancient Roman gladiators to modern-day sanguinarians.

Researchers are investigating GLP-1 applications for a variety of chronic conditions. One area of interest stems from how study participants using GLP-1 for diabetes and obesity reported describing less longing for wine and cigarettes while taking the medication—intriguing researchers about using the drugs for addiction applications. The drug, they theorize, could bind to receptors that mediate desire.

Archaeological evidence shows the use of the poppy plant for its pain-killing properties likely originated in the Mediterranean before making its way to the East and West via trade. It has since inspired two eponymous wars, and highly addictive derivatives of the naturally occurring substance have led to an ongoing overdose crisis.

Consumer Reports, which tests supplements for safety, urges consumers to avoid these four supplements due to safety warnings from researchers and public health authorities.

Diabetes treatment became truly effective after the advent of insulin injections in the early 1900s. Diabetes is becoming increasingly common. Current trends estimate one in three Americans will have diabetes by 2050. This overview explores two centuries of diabetes treatment—starting in 1812—and outline potential challenges to treatment and prevention.
