Commonly known as geranium, Pelargonium sidoides is part of a genus of flowering plants first cultivated in South Africa. Geraniums, which bloom in a variety of shapes and colors, are typically grown for their beauty; and some fragrant species of Pelargonium are used to create perfumes. But the P. sidoides species also offers medicinal benefits. It has a long history in tribal South Africa as being used to treat coughs, upper respiratory infections and gastrointestinal illnesses. P. sidoides is often marketed as EPs 7630 or Umckaloabo, meaning “heavy cough” in Zulu tribal language.
In the eighteenth century, seasoned sailors found that by sucking on lemons they could avoid scurvy, a debilitating disease that often developed during long voyages when fresh fruits and vegetables were scarce. When the lemon’s key nutrient was formally identified in 1928, it was named ascorbic acid for its anti-scurvy, or antiscorbutic, action. Today ascorbic acid is widely known as vitamin C.
This famed vision-enhancing nutrient was isolated in 1930, the first fat-soluble vitamin to be discovered. The body acquires some of its vitamin A through animal fats. The rest it synthesizes in the intestines from the beta-carotene and other carotenoids abundant in many fruits and vegetables.
What Is It? Famed as an energy tonic in China since ancient times, Siberian ginseng only gained recognition in the West in the 1950s, when a Russian scientist (I. I. Brekhman) reported its notable stress-repelling powers. Healthy men and women taking the herb were found to better endure physical strain, resist disease, and perform tests […]
An herb prized for its medicinal benefits and distinctive flavor, peppermint (Mentha piperata) is a naturally occurring hybrid of spearmint (M. spicata) and water mint (M. aquatica). Unlike other mints, however, peppermint contains in its healing volatile oil the powerful therapeutic ingredient menthol, as well as menthone, menthyl acetate and some 40 other compounds. The oil is made by steam-distilling the plant’s aromatic leaves and stems, which are gathered just before its light-purple flowers appear in the summer.
Along with the bold yet delicate taste that shiitake, maitake, and reishi mushrooms add to soups and other dishes, these gourmet delicacies are prized as herbal medicines. Traditional Asian healers have used them for centuries to strengthen the immune system and promote longevity. Recently, an extract from a different mushroom altogether–PSK (Coriolus versicolor)–was identified as a possible ally in the fight against cancer. While mushrooms other than these may well have specific health-promoting actions, they haven’t been as thoroughly researched for medicinal purposes.
Many North Americans probably don’t realize that the climbing ivy plant (Hedera helix), so often found in their gardens and yards, has a long history in folk healing. In its native Europe, the plant’s shiny, dark green leaves have traditionally been used for colds and congestion, for fighting fever (by inducing sweating), and for controlling parasites.
The Iroquois and Cherokee were among the first of the American tribes in the eastern United States to use this small perennial plant (Hydrastis canadensis) medicinally. They harvested its fleshy underground stems (rhizomes) and roots and used them to treat a variety of infections and other complaints, from insect bites and digestive upset to eye and skin ailments. By the nineteenth century, healers began to refer to this native wildflower (which resembles a buttercup) as goldenseal because the cuplike scars on its bright yellow rhizomes resembled the wax seals then used to close envelopes and certify documents. The plant’s colorful roots also provided dye for clothing.
Along with its well-earned reputation for discouraging friends and repelling potential lovers, this powerful herb has a storied culinary and medical history. Egyptian pyramid builders took it for strength and endurance. Medieval healers recommended it as protection against supernatural forces–vampires in particular. The French scientist Louis Pasteur investigated its antibacterial properties, and doctors in the two World Wars treated battle wounds with garlic juice when other drugs were unavailable. Most recently, garlic has been touted for heart health as well.
From cough cure to tension-reliever, the woody scented oil and leathery leaves of the stately eucalyptus tree have found myriad uses over the centuries. Australian aborigines relied on this native evergreen for soothing painful joints and healing skin lesions. And settlers to the continent dubbed eucalyptus the “fever tree” in recognition of its disease-fighting powers. While these early users ascribed its potency to the tree’s brisk aroma, it is now known that the thirsty roots were responsible: They kept the surrounding ground relatively dry and thus free of malaria-carrying mosquitoes.
One of the most popular herbal remedies in the world, echinacea contains active ingredients thought to fight colds, flu, and other infections. There are nine species of this herb, commonly called the purple coneflower, but just three (Echinacea angustifolia, E. pallida, and E. purpurea) are used medicinally. Various parts of the plant (flowers, leaves, stems, or roots) from a variety of species appear in literally hundreds of commercial preparations. Depending on the species and plant part used, the herb will stimulate the immune system and combat bacteria, viruses, and other disease-causing microbes.
Thought to have originated in Cayenne, French Guiana, cayenne is a spice derived from several varieties of dried hot peppers in the Capsicum species. Cayenne is a relative of the mild bell pepper used in salads and also of the fiery peppers found in chili powders and hot sauces, but it has no connection to black table pepper. Used for centuries by cooks around the world to add “heat” to traditional dishes, cayenne has gained a solid reputation both as a painkiller and digestive aid.
